Abstract: 554,951. Abrasive tools containing diamond grains &c. SVENSKA DIAMANTBERGBORRNINGS AKTIEBOLAGET. March 2, 1942, Nos. 2750 and 2751. Convention dates, March 21, 1941, and July 26,1941. [Class 70] Diamond grains &c. for abrasive tools are entirely embedded in a powder of such small particle size, e.g. 0.002 mm. that irregularities in the diamond surfaces are substantially filled, whereupon the interstices between particles of powder are filled with a molten metal or an alloy of lower melting point than that of the powder. As powder may be used tungsten carbide, cobalt, nickel, or iron, and there may also be included powder not wetted by the casting metal or alloy e.g. silicon carbide, to enable resistance to abrasion to be adjusted. The casting metal may be copper, or hard solder and may be applied with the aid of a flux e.g. borax. Casting and cooling may occur in a reducing atmosphere, and the grains and powder may be previously packed under pressure, and the grains may be moistened with e.g. a light mineral lubricating oil before the powder is added.

Abstract: 665,297. Coating webs. CULLEN, CARVER & WILSHAW, Ltd., GENT, S., ORTON, Ltd., E. J., and CULLEN, P. C. Feb. 2, 1950 [Feb. 2, 1949], No. 2888/49. Class 140. In a machine for making paper bags wherein a web 1, of paper has a line of paste applied to it by a disc 2 rotating in a trough of paste 6, an alarm device or device for stopping the machine is incorporated to operate when the supply of paste to the web is interrupted. The alarm device may be a signal lamp or a buzzer. A wire 5 provided to sever the web 4, of paste between the disc, and web 1 of paper and insulated from the machine frame. arid the disc 2, naturally connected with the frame through its spindle and bearings, form part of an electric circuit including the alarm device. A suitable circuit is shown in Fig. 3, the wire 5 being connected to the grid of a thermionic amplifier 7, the anode circuit of which is fed from the mains 8 through a transformer 9. The cathode circuit includes a bias resistance 10 and relay 11 both bridged by a condenser 12. A leak resistance 13 connects the grid to the cathode. The earth terminal 14 is joined to the machine frame. While current is flowing through the wire 5 and disc 2 the grid is maintained at negative potential relatively to the cathode, and the current flowing through the valve is insufficient to excite the relay 11. Should the supply of paste be interrupted the flow of current is not maintained and the grid of the valve comes to cathode potential and the current through the valve increases to an extent which operates the relay 11 to close contact 15 to operate the alarm signal or stop device 16. The circuit containing the alarm or stop device may be supplied from the mains 8 or from a secondary winding on the transformer.

Title: Improvement in airship mooring masts and controls therefor
IPC: B64F1/14
Filed: 1929-01-28
Abstract: 305,629. Waterbury Tool Co., (Assignees of Crain, J. J.). Feb. 8, 1928, [Convention date]. Hydraulic transmission of power; speed - varying mechanism. - Relates to means for winding-in the cable of an airship moored to the top of a tower, in which a cable drum is located at the base of the tower, the cable thereof extending to the top of the tower, and consists in a hydraulic speed gear for driving the drum, a fluid pressure pump and motor and means for varying the speed of the operation. The pump has an adjustable control operated from a hand wheel at the base and at the top of the tower, indicating means being provided for showing the lineal speed of travel of the cable. A spring- pressed locking device indicates the neutral position. An automatic spooling device is used for the drum of the mooring cable. As shown, the winding drum 12, Figs. 1 and 2, with an automatic spooling device 51, for the cable 50 is driven through a reduction gear 16 from the shaft 19 of a motor 20, itself being driven from a pump 23 rotated by a prime mover 26 of constant speed. The lay-out of the successive machines as in Fig. 2 provides a compact arrangement. The pump 23 and hydraulic motor 20 are similar in construction and are of the swash plate type shown in Fig. 5, but whereas the inclination of the swash plate of the motor is fixed, that of the pump is variable by means of a hand-wheel 44, and shaft 38, the latter having an internally-threaded enlargement 37, engaging a screw-threaded part 39 of a shaft 36. The latter shaft is secured by a connection 35 to the tilting box 32 of the pump. The tilting box is provided with a race for the rotation of a swash plate 31 connected to rods 30 attached to pistons 29 working in cylinders 28 in a block 27 secured to the main driving shaft 24. Arcuate shaped ports in the pump casing 34 alternately connect to ports 33 connected to the cylinders 28, and are in communication by pipes 22, 21 with similar arcuate ports in the motor casing. Corresponding to the hand wheel 44 at the base of the tower is another hand wheel 63, Fig. 6, at the top of the tower, both wheels having corresponding flanged drums 43, 57 over which passes the same cable 55 to ensure synchronization and to enable control of the pump to be effected from either of the two positions. Corresponding indicating dials 45, 65 for the rate of winding, and gauges 66, 70 for the fluid pressure are also provided at the two stations. A notched disc 71 with a spring pressed stop 73 serves to enable the operator to feel the neutral position of drive.

Title: Improvements in or relating to Recording Apparatus.
IPC: H04N1/08
Filed: 1968-01-19
Abstract: 1,177,474. Facsimile recorders. ROBERT BOSCH G.m.b.H. 19 Jan., 1968 [20 Jan., 1967], No. 2954/68. Heading H4F. In a facsimile recorder employing a rotatable recording drum 10, instead of using separate sheets of recording carrier, the recording carrier is in the form of a continuous web 11, 12 stored within the drum on a rotatable sleeve 14, and the required length of the carrier is unrolled from the sleeve through an axial slot 13 in the periphery of the. drum and secured to the surface thereof for recording. Sleeve 14 is prevented from rotating independently of the drum by means of a multiple disc brake 17, secured within the sleeve on a spindle 16, and a torsion spring 19 secured between the body 17a of the brake and the end face 14a of the sleeve. The braking force of the brake is determined by the initial tension of a compression spring 18. In operation after the storage roll 12 has been inserted in the drum (by removing flange 23) the carrier 11 is drawn manually out of slot 13 which stresses spring 19 due to the rotation of sleeve 14. With spring 19 tensioned, the braking force of the brake is exceeded and the recording carrier may be unrolled and laid around the drum and its end 11a clamped by means of lift-up clamp 20 which is held down by permanent magnets 21. Clamp 20 has a cutting edge 20a. Return of the sleeve 14 is prevented by an eccentrically mounted pressure roller 24. When the drum 10 is rotated, roller 24 is lifted from sleeve 14 by centrifugal force and spring 19 becomes operative to tension the carrier on the drum and apply the brake to sleeve 14 so that the drum and sleeve rotate with shaft 16. The carrier may have an evaporated metal coating which is inscribed by electrically burning out the metal coating by a recording electrode, clamp 20 serving as an earthing electrode..

Title: Improvements in stamping or embossing machines
IPC: A43D95/14
Filed: 1943-02-25
Abstract: 560,744. Embossing machines ; tripping arrangements. POCHIN, H. W., and DOVE, G. H. Feb. 25, 1943, No. 3127. [Class 100 (ii)] In an embossing or stamping machine which is described for the stamping of soles, the pressureapplying device acts upon levers h<1>, il pivoted to the frame a of the machine and serving to actuate the die-plunger c and the plunger a' which supports the work anvil b. The lever i<1> is pressed upwards by an adjustable spring k, and the pressure is applied by toggle links h, i actuated by a primary toggle device g<1>, g<2> actuated by an electrical thruster d, which may be of the kind disclosed in Specification 363,137, [Group XXIX]. This is energized by a switch d<1> operated by a pedal d<2>, and it raises a crosshead e slidable on guides e<1>, and serving to transmit motion via springs e<2> to a second crosshead e<3> which is raised against the action of a spring e<4>. Links f serve to straighten the primary toggle which thereupon straightens the toggle h, i and causes the die c<1> to act upon the work. The pressure upon the work is dependent upon the extent of lowering of the pivot i<3> and the levers h<1>, i<1> are arranged so that the straightening of the toggle h, i causes only a small amount of lowering so that the working pressure may be substantially constant for different thicknesses of work. Should the levers be set wrongly so that the thruster is unable to straighten the toggles, an additional movement will be given to the cross-head e and a switch will be tripped to break the electrical circuit, whereupon the spring e<4> will return the thruster. The toggle h, i may be operated by a crank and connecting rod, and a dashpot used to control the return of the pressure spring. An adjustable stop collar m limits the movement of the work plunger.

Title: Improvements in or relating to fluid pressure servo mechanism for operating brakes, clutches or the like
IPC: B60T13/24
Filed: 1934-01-30
Abstract: 420,858. Operating clutches. CLAYTON DEWANDRE CO., Ltd., Titanic Works, and FAGARD, J., 24, Eastgate, both in Lincoln. Jan. 30, 1934, No. 3160. [Class 80 (ii)] [See also Group XXXIV] Combined fluid-pressure and manual brake or clutch operating mechanism for motor vehicles having automatic follow-up action to reclose the control valve comprises a spring 7 through which the effort communicated to the pedal 1 is transmitted to the brake transmission 2 and a control valve 9 connected to the pedal and transmission so that the manipulation of the valve depends on the strain on the spring, the spring and the valve connecting the pedal and transmission through separate links. The spring 7 and the valve 9 are connected by rods to the opposite ends of levers 4, 5 mounted on pedal shaft 3 and transmission shaft 2 respectively. When the pedal is operated the link 6a, 6b is elongated and the spring 7 is compressed and the rods 8<a>, 8<b> slide relatively to operate the valve which controls a brake cylinder connected to the brake transmission. In a modified form the link 6<a>, 6b is arranged so that it is shortened on brake operation. In a further modification the spring and the valve are connected to lever arms on the same side of the shafts 2, 3. In these modifications the valve 9 is constructed so that as the link 8<a>, 8<b> is altered in length the ports gradually open or close. In further modifications the ratio of the lever arms is different so that the tension of the spring 7 at each stage of braking is increased as the braking effort is increased. In a further modification the lever 5 is cranked so that the rate of increase of tension of the spring 7 decreases as the braking effort increases. These two modifications are provided with a valve having a simple opening and closing action and comprising a tube 8<b>, Fig. 5, and a casing 10 connected to the rod 8<a>. Port 14 is connected to a source of fluid pressure and port 15 to the brake cylinder. Relative movement of parts 8<a>, 8<b> on brake application is adapted to seat the tube 8<b> on a valve 13 to close the atmospheric port 12 from the port 15 and to raise the valve 13 from a seating in the casing 10 to connect ports 14, 15.

Title: Improvements in or relating to a method of applying ceramic colour, and compositionstherefor
IPC: C04B41/86
Filed: 1951-02-09
Abstract: 722.801. Enamels and enamelling. DRAKENFIELD & CO., Inc., B. F. Feb. 9, 1951 [Feb. 10, 1950], No. 3190/51. Addition to 648,209. Class 56 A composition for applying ceramic colour to a ceramic receiving surface comprises a dispersion of enamel frit carrying a ceramic colour in a vehicle comprising a thermoplastic resin, a solvent for the resin, and a wax present in an amount in excess of its solubility in the composition at normal room temperatures, the composition being solid at normal room temperatures and meltable for application to the surface where it promptly solidifies, and the vehicle being volatilizable without leaving objectionable residue when the composition is heated to fuse the frit. When using more than one colour, no intermediate drying stages are necessary. The ceramic colour may be any known inorganic colouring agent, and is added as a mill addition or is initially fused into the frit. A resinous wood product thermoplastic resin is preferably used, particularly hydrogenated wood rosin. Wood rosin and limed wood rosin are useful because they also wet glass. Other suitable materials are polymerized normal butyl methacrylate, resinous chlorinated diphenyls, alkyd resin, and ethyl cellulose, preferably of high viscosity, several specific examples being given. Examples of suitable solvents for the resin are given, but normal butyl methacrylate requires a high boiling petroleum solvent. The compositions suitably have' a melting range of 140-200‹ F. Suitable waxes for obtaining a prompt solidification of the composition are specified synthetic waxes, stearic and palmitic acids, which also lower the melting point of the resins, carbowax and its stearates and oleates, and waxes made by reaction of such solid acids as stearic, adipic and phthalic with fatty amines. Mixtures of waxes may also be used. If neither wood rosin nor limed rosin is present, carbowax 4000 is used as a wetting agent. The viscosity of the composition may be adjusted by adding, for example 1-10 per cent of a bodying agent such as ethyl cellulose. For many purposes the ratio colour:frit varies from 1:1 to 6:1 by weight. A suitable general vehicle contains equal parts by weight of hydrogenated wood rosin, hydrogenated methyl ester of rosin, and stearic acid amide, and 4 per cent. N200 ethyl cellulose and 6 per cent. of carbowax 4000 may be added. Several other examples are given. The coloured frit is stirred into the molten composition, and the resultant mixture is suitably applied by the squeegee or silk screen process. Heat, as from infra red lamps, is commonly applied to the stencil screen to prevent solidification on the screen.

Title: Improvements in or relating to liquid pressure remote control systems
IPC: F15B7/10
Filed: 1936-02-05
Abstract: 468,975. Hydraulic transmission of power. CLENCH, E. C. S., and AUTOMOTIVE PRODUCTS CO., Ltd. Feb. 5, 1936, No. 3527. Addition to 443,839. [Class 69 (ii)] The invention described in the parent Specification is modified, in that means are provided for positively preventing the byepass valve device from being automatically opened, due to the operator letting go of the handle while the latter is disposed within a predetermined part of its range of movement. The operating handle 11 is mounted on a shaft 12 which carries a crank 34, and on this is a pin 35 carrying a roller 36 which moves within a slot 37 in the connecting piece 17 of the two piston elements 16, 16a. This connecting piece carries also a projection having a notch 70 into which a spring-pressed detent can enter when the pistons are in mid-position. A flange on the shaft 12 carries a sleeve having a flange 41, and upon this are mounted a masking cam member 44 and an outer sleeve 45 all spring-pressed together so as to be frictionally operated through rings 42, 43 from the flange 41. The member 34 has an upstanding part 44 with a detent opening into which the nose of a lever 55 can move when the pistons are in the central or nearly central position. The levers are connected to a lever 32 which acts upon a ball valve for the cylinder to be coupled to a make-up reservoir. The detent member 55 is wider than the cam plate and overlaps the disc 46 which is provided with an upstanding flange 82 over a portion of its circumference, and acts as a masking plate to prevent the detent 55 entering the slot 44 and so preventing the final lever 32 from acting on the byepass valve to put the apparatus into communication with the reservoir. The casing 10 serves as a reservoir and is adapted to be filled through a stopper 20. This stopper is utilized to carry a spring-restrained button 21 which button, when pressed inwardly, acts upon a lever 59 and so ultimately upon the lever 32 to positively open the system to the relevant reservoir.
