Title: Improvements in or relating to sewing machines
IPC: D05B19/00
Filed: 1962-03-12
Abstract: 938,706. Sewing machines. G. M. PFAFF A.G. March 12, 1962 [March 14, 1961], No. 9339/62. Class 112. In a zig-zag sewing machine the needle bar oscillation is controlled by a pack of rotary cams co-operating with followers carried by a member pivoted on an axis concentric with the axis of rotation of the cams. A pack of six pattern cams 6 is fixed to a rotary shaft 6a journalled in a base-plate 1 and driven from the arm shaft of a zig-zag sewing machine. A ring 5, mounted for rotation in a groove formed in plate 1 concentric with shaft 6a, is provided with a radial arm 4 which is connected by a link 4<SP>1</SP> to the needle bar gate. Six pins 7, which are rotatable and axially slidable in plate 1 and a spaced ring 16 carried by brackets 15, have fixed thereto arms 9 the inner ends of which can serve as followers to the respective cams. A spring 8 acting on an arm 9 biases the latter clockwise to abut a rod 11 for separating the inner end from the cam, and also biases arm 9 upwards out of adjustment with the cam. A spring 3, acting on arm 4, then turns ring 5 anti-clockwise to position a series of six pins 10 carried thereby and of various heights partly under the outer ends of the arms 9 with which the pins are associated. A knob 12, pivoted on shaft 6a and rigid with a six-lobed cam 13, is formed with a cam lug 14 adapted to co-operate selectively with the pins 7 for depressing the latter. Simultaneously with the depression of a pin a pair of lobes on cam 13 rock a pair of levers 18 pivoted on ring 16, whereby the levers co-operate with a pair of pins 17 extending upwardly from ring 5 to turn the latter clockwise. The pin 10 associated with the depressed pin 7 is thereby moved clear of the latter, and on completion of the adjusting movement of knob 12 when lever 18 engages the trough of cam 13, spring 3 turns ring 5 to engage said pin 10 with the outer end of its associated arm 9 for engaging the inner end of the latter with its associated cam. Ring 5 may be divided into two or three segments, each connected to a link controlling a function of the sewing machine, e.g. needle swing, needle mean position and work feed.

Title: An injection moulding process
IPC: B29C45/46
Filed: 1961-03-14
Abstract: 960,616. Injection moulding processes. COMPAGNIE DE SAINT-GOBAIN. March 14, 1961 [March 14, 1960], No. 9362/61. Heading B5A. In an injection moulding process a pulsating injection pressure is used. The process is described with reference to the manufacture of fibre reinforced polyester resin articles. The fibre reinforcement, preferably as a preform containing a polyester base binder comprising 5-10% by weight of the reinforcement is placed in a female mould section and clamped therein. A male mould section is lowered into position and clamped either pneumatically or mechanically. The reinforcement may be dried by circulation of hot air in the mould. Uncured polyester resin is then injected from the base of the female mould section to fill the mould and expel air through vents provided in the top of the mould. The pulsating pressure employed during the injection stroke may be obtained by the use of pressure reducing valves. Alternatively a constant injection pressure is utilized on which is superimposed a pulsating pressure obtained by reciprocation, by use of a cam, of a piston in a cylinder connected with the injection passage and filled with resin. Frequencies of 0.2 to 5 pulsations per sec. and pressures of 0 to 10 kg/cm.<SP>2</SP> are suitable, but negative pressures may be obtained where a super. imposed pulsating pressure is employed. In suitable catalytic conditions greater injection speeds may be obtained by the use of higher temperatures to lower viscosity of the resin and to effect this the mould may be heated. Alternatively the mould may be left slightly open during injection of the resin, the mould then being progressively closed to compress the resin and the reinforcement. In another alternative arrangement part of the mould may be made to reciprocate during injection of the resin the pressures created by this reciprocation being in antiphase with those of the injection pressure. Depending on the mould used, delay of the injection pressure in reaching the reciprocating part of the mould may have to be allowed for. After filling the mould the resin is cured in an oven.

Title: Improvements in or relating to antibiotics and the preparation thereof
IPC: C07G11/00
Filed: 1951-04-23
Abstract: An antibiotic thiolutin is produced by cultivating in a nutrient medium a strain of Streptomyces albus, the cultural characteristics of which are described, or a mutant thereof.  The antibiotic is effective against bacteria and fungi, neutral, slightly soluble in water, contains the elements carbon, hydrogen, oxygen, nitrogen and sulphur, and the mineral oil suspension shows characteristic absorption bands in the infra red region of the spectrum especially at 3295, 3220, 3110, 1680, 1645, 1607, 1551, 1439, 1322, 1239, 1138, 1091, 1060, 1039, 975, 875, 825, 800, 740, 729.  The ultra-violet absorption spectrum is characteristic.  It is soluble in organic solvents such as butanol, methanol, ethanol, acetone, methyl isobutyl ketone, glacial acetic acid, dimethylformamide, chloroform, pyridine and isopropanol; less so in petroleum ether, benzene and hexane.  The antibiotic is produced by growing the micro organism in a nutrient medium containing (a) carbohydrate, e.g. sugars, starch and glycerol, (b) organic nitrogen source, e.g. soybean meal, cotton seed meal, peanut meal, corn steep liquor and N-Z-Amine B (enzymatic digest of casein), (c) mineral salts, e.g. sodium chloride, sodium nitrate, magnesium sulphate and potassium phosphate, (d) buffer, e.g. calcium carbonate and potassium dihydrogen phosphate, (e) antifoaming agent, e.g. vegetable or animal oil.  The pH is adjusted to 6 to 7, the temperature is 23 DEG  to 32 DEG  C., and preferably 26 DEG  to 30 DEG  C., the duration of treatment 2 to 7 days with agitation and aeration at the rate of 1/2 to 2 volumes air per volume of broth per minute.  The antibiotic is recovered from the clarified broth by (a) solvent extraction with water-immiscible organic solvents at acid, neutral or basic pH, but preferably at acid or neutral pH.  Alcohols, esters, ketones, hydrocarbons, ethers and chlorinated solvents may be used, and in particular butanol, ethyl acetate, methyl isobutyl ketone, benzene and chloroform; (b) absorption on, e.g. activated carbon followed by elution with a solvent.  The broth is clarified by driect filtration with a filler aid, or after acidification to preferably pH2 and heating to 70-90 DEG  C. for 10 to 60 minutes. The antibiotic may be crystallized from solvents such as alcohols, e.g. methyl alcohol, ketones, dimethylformamide or mixtures thereof with water.  Suspensions of the antibiotic in peanut oil or sesame oil when injected into mice were less toxic than when the antibiotic was taken by mouth.

Title: Improvements relating to electric fuses
IPC: H01H85/046
Filed: 1949-04-07
Abstract: 670,926. Fusible cut-outs. STRONG, H. V., and EISLER, P. April 4, 1950 [April 7, 1949], No. 9493/49. Class 38 (i). [Also in Group XXXVII] Ina fuse assembly, the fuse link comprises metal foil at least partly coated with a thin film of a heat-sensitive explosive coating composition, thereby releasing a secondary rupturing effect when the link is subject to its rupturing current. In Fig. 2, the link 20 is coated with a thin band of explosive composition such as lead styphnate paint. The link is bent over a hump-shaped holder 12 having a space 15, so as to stress the link whereby when the composition explodes, the broken ends of the link fly apart. The outer ends of the link overlie tags 16, said ends and tags being soldered to the base terminals or contacts. Alternatively the link may be stressed by placing it under tension, in which case it may, be used on a flat holder. Fig. 5 shows another embodiment wherein three fuse links 26, 27, 28 comprising thin metal foil mounted on a backing of insulating material, for example by a printed circuit technique, are delta-connected. The space between the dotted lines is coated with explosive paint so that all the links will be ruptured on the rupturing of any one link. A temperaturesensitive coating may be applied to the link or links which changes colour on a substantial overload. The Provisional Specification describes a construction in which two fuse links are connected in series with a lead taken from their common connection to form a Y. A blob of explosive material is placed at the common connection to cause separation of the three branches when one link ruptures. It refers also to the use, instead of the explosive paint, of a foil of higher melting point overlying two arms and the junction, leaving the third arm uncovered. Specifications 639,111 and 639,658 are referred to.

Title: Improvements in or relating to electromagnetic relays
IPC: H01H51/06
Filed: 1924-04-16
Abstract: 231,676. Richter, M. B. April 16, 1924. Relays, contact-making. - The magnetic circuit of an electromagnetic relay comprises an iron core for the energizing coil, an L-shaped yoke connected to one end of the core and projecting over the other end, and an armature pivoted on the projecting end of the yoke to turn about an axis parallel to the core, one of its arms cooperating with the end of the core and the other arm with the contact springs. Figs. 1 and 3 show a double or step-by-step relay in which two such units are structurally united while maintaining their magnetic circuits independent. The vertical portion of each yoke. 1 is formed with a slot in which the core 4 is secured, and the horizontal portion is formed with an obliquely-cut slot 5 parallel to the axis of the core. The armature 6 passes through the slot 5 'and is provided with knife edges 8 bearing on the upper surface of the yoke Its upper arm 9 is staggered as shown in Fig. 3 and its lower portion is formed with a hole through which extends a non- magnetic bolt 11 secured to the core 4 and provided with a head 12 constituting a stop. To prevent sticking the armature carries small stops or the core is provided with a thin non- magnetic covering. In the double relay the vertical portions of the two yokes are secured to a brass plate 13, and the other ends of the yokes are connected by a similar plate 14 provided with slots through which the cores 4 extend. An oval hole 31 is provided in the plate 14 to admit an expanding tool for pressing the edges of the slots against the cores. The contacts are carried by springs supported from turned-up portions 2, Fig. 1, of the yokes, and in the double relay shown those on the left are opened and those on the right are closed by the operation of the corresponding armatures. The left-hand armature 6 bears on an insulator 28 carried by the spring 20 and passing freely through the springs 19 and 21, and the spring 19 carries an insulator 29 bearing against the armature and thus acts to return the armature to normal position, Fig. 3. The right-hand armature 6 bears on an insulator 27 carried by the spring 25 and passing freely through the spring 24, and the springs 22 and 24 carry respectively insulators 30 and 35, Fig. 10, bearing against the armature, and thus act like the sprring 19 to return the armature to normal position. For ensuring sensitiveness. however, the insulators 30, 35 are arranged to be slightly removed from the armature when the latter is fully operated.

Title: Improvements in and relating to apparatus for the analysis of substances by absorption of infra-red radiation
Inventor: MARTIN ALBERT EDWARD
IPC: G01J3/12
Filed: 1961-03-16
Abstract: 930,698. Infra-red fluid analysis. Sir HOWARD GRUBB PARSONS & CO. Ltd. April 16, 1962 [March 16, 1961], No. 9677/61. Class 40 (3). The invention relates to apparatus for the analysis of substances by absorption of infrared radiation and comprises an infra-red source 1, a cell 2 for containing a sample under test, an infra-red detector 3, for example a thermocouple or an indium antimonide cell, which receives the radiation from the source 1 via the cell 2, an optical filter 5 in the radiation path for passing a desired wavelength region in which the sample has appreciable absorption and a rotatable disc of material 6 transparent to at least a portion of the radiation transmitted by the filter, the disc being coated or covered over a portion of its area (Figs. 1a and 1b, not shown) such that the said portion has absorption bands or interference fringes overlapping the region of absorption of the sample so that when the disc is rotated an alternating signal is produced by the detector which is related to the absorption characteristics of the sample. With the cell empty, Fig. 2a shows by curve A the spectral distribution received by the detector 3 when the radiation is passing through a transparent sector of the disc and by-curve B the spectral distribution received by the detector when the radiation is passing through a coated sector of the disc. Fig. 2b shows the curve c obtained with a sample in the cell when the sample has an absorption band nearly coincident with that of the coated sector D. With the disc rotating the difference in the absorption of the sample and the coated sector of the disc as shown by curves C and D produces an alternating signal at the detector which is amplified by an amplifier 8 and fed to an output meter 9 or pen recorder which gives an indication of the concentration of the particular substance under investigation in the sample. The apparatus may be used for the investigation of substances having a substantially uniformly-spaced set of vibrationrotation absorption bands in which case the diso is made of material e.g. mica which produces regularly-spaced interference fringes with transmission troughs between the fringes coinciding with the rotation bands of the substance under investigation and the coated sectors of the disc are coated on one or both sides with material e.g. zinc sulphide of higher refractive index than the material of the disc.

Title: Ram type press
Inventor: WILLIAMSON FLOYD MITCHELL
IPC: B21D22/02
Filed: 1964-03-07
Abstract: 1,049,115. Stamping. DI-DRO ENGINEERING CO. March 7, 1964, No. 9757/64. Heading B3Q. A press for forming operations in sequence on a workpiece 108 during the working stroke of the press-ram 14 comprises opposed dies 16, 18, 30, 32, hydraulic cushions 40, 48 for the dies 18, 32 connected to a tank 52 containing hydraulic fluid under pressure for extending the dies, and pressure relief valves 92, 102 in the supply lines between the tank and the cushions, valve 92 for cushion 48 being set to open at a lower pressure than valve 102. The top die assembly comprises an outer shearing die 28 fixed to a bolster 12, the peripheral die 32 and a central die 30, the dies 30, 32 being biased away from the bolster by pistons 44, 48 in cylinders 46, 50. The lower die assembly comprises a central die 16, a stripping plate 126 spring-urged to eject the margin trimmed from the work by the die 28, and a lower peripheral die 18 which is biased away from the lower bolster 10 by pistons 40 in cylinders 42. Hydraulic fluid, under pressure by compressedair, is supplied to the cylinders 46, 50 along lines 56, 70 and past a check valve 64. A similar supply to cylinders 42 along lines 74, 80, 88, 90 passes a check valve 82. In the starting positions of the press the dies 18, 30, 32 are extended by the cushioning pistons 40, 44, 48. The work is clamped between the dies 18, 32 as the ram descends for trimming the margin of the work. The top bolster 12 approaches the die 32 which is prevented from moving by the lower die 18. Further movement of the ram forms the work between the dies 16, 30. The die 32 now bearing against the bolster 12, is moved by continued descent of the ram, causing an upwardly formed lip on the work to curl downwardly forming a rolled edge 108. In this last movement, the pistons 40, 44 retract as the dies 18, 30 come to bear against the bolsters. During retraction of the die 18, fluid passing from the cylinders 42 back to the tank along line 98 and past valve 102, enters a passage 110 in a valve block 76. This passage is connected by passages 116, 118 to a space behind a spool valve 114 which is moved by the pressure fluid to close off line 80. Thus, when the ram is raised, the pistons 40 will not raise the die 18 and the work until a spring 122 has returned the valve 114, the pressure fluid behind the valve being exhausted past an adjustable valve 124. The delaying device may be associated with the other cushion pistons, and each hydraulic cushion may have its own pressure relief valve.

Title: Improvements in or relating to percussion fuzes
IPC: F42C15/20
Filed: 1938-03-31
Abstract: 513,725. Projectile fuzes. SAGEB SOC. ANON. DE GESTION ET D'EXPLOITATION DE BREVETS. March 31, 1938, No, 9814. Convention date, April 2, 1937. [Class 9 (i)] The firing pin 4 of a percussion fuze for an aerial bomb or the like, is screwed on to the lower end of the spindle 8 of a clockwork mechanism, and is held at safe by a cross-pin 19, at the lower end of a tube 20, which engages in a slot 21 in the upper portion of the spindle 8, the tube 20 being locked against balls 26, Fig. 6, or the like, by a spring 22 encircling a rod 25 furnished with a necked portion 28, which the spring tends to bring opposite the balls to allow upward movement of the tube 20 to effect arming of the fuze, displacement of the rod 25 being prevented, until release of the bomb, by a member 31 detachably secured to the upper end of the rod 25. The member 31 comprises two spaced limbs 32, Fig. 11, the ends of which are provided with members 44 which grip fiats 33 formed near the upper end of the rod 25. The member 31 is disengaged from the bomb by a cable 36, and the rod 25 then moves downwardly under the action of the spring 22 to bring the neck 28 into line with the balls 26, which latter move inwardly and thus allow the spring 22 to raise the tube 20 and withdraw the cross pin 19 from the spindle 8. The spindle 8 is then rotated by the clockwork spring 12, against a helical spring 6, to disengage the striker pin 4 from the spindle and thus arm the fuze. The end of the outer tube 20a is closed by means of a screwed cover 30a furnished with a packing ring 30b. During transport, the member.31 is rotated into alignment with the rod 25 and secured by means of a safety-pin or the like, and in this position the rod 25 is raised by the members 44 of the member 31 to bring a flange 30 on the rod 25 into contact with the packing ring 30b.
