Title: Improvements in or relating to infra-red analysing apparatus
Inventor: MARTIN ALBERT EDWARD
IPC: G01N21/37
Filed: 1953-04-24
Abstract: 749,689. Infra-red gas analyser. PARSONS & CO., Ltd., C. A. April 13, 1954 [April 24, 1953], No. 11423/53. Class 40 (3). In apparatus for infra-red absorption analysis of gases, radiation is passed in a single path through an absorption tube, is periodically interrupted and is received by a detector containing a gas capable of being heated by the radiation absorption, the resulting pressure fluctuations causing a thin metal diaphragm to vibrate near a fixed electrode. As shown in an arrangement for detecting ethylene in a mixture of ethylene and ethane the sample gas is contained in a tube b having infra-red transparent windows o. The radiation then passes through a similar filter tube p<SP>1</SP> containing ethane, a tube q containing ethylene and is finally received in a detector chamber d containing ethylene which expands when radiation is received and deforms a diaphragm f which with a fixed perforated electrode g forms a condenser. So that the radiation shall be pulsating, tube q is connected to a chamber h, the effective volume of which is periodically varied by a motor-driven connecting rod l reciprocating a diaphragm j, thus the effective concentration of ethylene in the tube q is cyclically varied so that a pulsed output voltage may be derived from the condenser in detector d. In a modification (Fig. 2, not shown) a double cell is provided instead of tube q, this cell being reciprocated so that empty and gas-filled parts are inserted alternately in the radiation path. In a still further arrangement a rotating chopper may be interposed between the infra-red source and the sample tube. The blade of the chopper may be opaque or partly transparent, e.g. plastic material with suitable absorption characteristics.

Title: New and improved method and apparatus for drilling wells and the like
IPC: E21B6/00
Filed: 1924-05-09
Abstract: 215,778. Smith, E. May 9, 1923, [Convention date]. Bore-hole apparatus. - Wells &c. are drilled by imparting reciprocating motion to one member and converting such motion into rotary motion of another member carrying a cutting tool which cuts by rotation only, the torsional strength of the first member being utilized to overcome the resistance of the material, to the exclusion of means for engaging the walls of the well &c. As shown, a member 26 is guided in a casing 20 by a closure 24, a guide 27 and a plunger 28; the casing carries the cutter 18 and a conebarrel 19. Ratchet wheels 36, 37 have each a spiral rib engaging one of two opposed spiral grooves 31, 32 in the member 26 and engage pawls carried by the casing whereby, when the member 26 is reciprocated by a walking beam through a cable, rod or tube, the casing and cutting tool are continuously rotated. The grooves 31, 32 may differ in pitch or one of the grooves may be straight, rotation of the tool then occurring only during the upward movement of the member 26. During upward movennt of the member 26, the plunger 28 draws fluid through ports 43 and past a valve 44 into the casing 20, this fluid, during the downward stroke, being forced past a ball valve 47 and through the tool. Specifications 5359/06 and 118,636 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) states also that the reciprocating motion may be converted into rotary motion of the cutter by means of hydraulic pressure built up by such reciprocation, by the use of gears and chains, or by reaction between a lug on one member and a spiral groove in the other member. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to automatic weighing machines
IPC: G01G13/00
Filed: 1949-05-02
Abstract: 661,310. Automatic feed weighers; steelyards. AUTOPACK (LONDON), Ltd., LEE, G. A., SMITH, A. R., and HOPKINS, C. J. May 1, 1950 [May 2, 1949], No. 11612/49. Class 143 [Also in Group XXXII] In an automatic feed weigher, oscillatons of the weigh beam f are damped by a rapid succession of braking engagements between a shoe t and resilient member u, the arrangement being such that movement of the beam consists of a rapid succession of steps closely simulating continuous motion. The shoe t which is rigidly secured to the beam by a rod s has a curved profile cbncentric with the fulcrum h, and the member u is secured to a shaft w continuously oscillated by a follower 4 which is secured to the shaft by an arm x, and which is forced into engagement with a continuously rotating cam 6 by a spring 5. The cam shaft z is rotated through bevel gears 2 by a shaft m which also drives impeller blades n arranged to effect a rapid flow of material from a hopper a to the weighpan e. Cut-off and a series of throttled dribble feeds are effected by a step-by-step movement of a slide d across the feed channel c. Movement of this slide is controlled through a crank 8a, a shaft 9, a gear 15 rigidly secured to shaft 9 and a gear 11 frictionally driven by camshaft z, an escapement mechanism allowing the gears 11, 15 to rotate through a predetermined angle each time a contact 31 is engaged by a contact shoe 26 secured to the beam. The escapement mechanism, Fig. 3, consists of a number of electromagnets 21, 22, 23, 24 and 25 each adapted to move a pawl 17 against the action of a spring 20 into the path of a resilient abutment 19 or 19a carried by the gears. The spacing of these magnets is such that the slide d opens the channel c quickly at the commencement of the weighing operation and then slowly throttles it step-by-step until, when the predetermined weight has been discharged, it effect cut off. The topmost contact 31 is in circuit with an alarm bell which is operated if an overweight charge is delivered to the pan e. Discharge of the pan is effected by reciprocation of a rod 36 which, when moved to the left consequent upon electromagnet 38 being energized by engagement of a contact 42 on shaft 9, see also Fig. 3, with a fixed contact 42a, lifts a latch 35 and operates an arm 33 which opens the doors q; springs r, 41 being provided to return the mechanism to normal when magnet 38 is de-energized.

Title: Oxysalt Compositions and Processes of Making same.
Inventor: CATLETT CHARLES
IPC: C01F11/20
Filed: 1919-05-09
Abstract: 126,646. Catlett, C. May 9, 1918, [Convention date]. Cement, Portland, treating after manufacture; compositions containing lime and salts; concretes and mortars.-Calcium oxychlorides arc produced by combining calcium chloride and oxide in such proportions and under such conditions that the material sets and can be pulverized and stored, but on the addition of excess of water, dissociates into its constituents. In an example, to 100 parts of quick-lime are added 60 parts of commercial calcium chloride dissolved in 50 parts of water. The mixture sets to a substantially dry, friable mass which is ground and can be stored. The proportion of chloride may be varied, but preferably lies between 25 and 35 per cent of the mixture, although the percentage may be as low as about 2, and as high as will combine with all the lime. The presence of magnesium salts in the lime and chloride is not objectionable. The powder is added to Portland cement, or lime concretes, usually in the proportion of 1¢-5 per cent, but proportions up to 10 per cent may be added. The oxychloride may also be added to hydrated dolomitic lime in such proportions that the calcium chloride is about 1 per cent. of the whole, and the powder thus obtained can be stored until required. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of oxysalts in general. It also states that a hydrate and chloride may be added separately to cement, and that calcium chloride may be added to hydrated magnesian limes to produce a cement. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the manufacture of ply fabric for reinforced rubber articles
Inventor: WALDRON FELIX WALTER
IPC: B29D30/42
Filed: 1961-03-30
Abstract: In producing bias-cut ply material from a strip of rubberised ply fabric having warp cords of nylon or rayon the strip is wound helically upon a pair of rotatable drums to form a tubular length, the helical joints between adjacent helical turns being continuously consolidated by pressure rollers, and that length is then continuously cut to produce at least one continuous length of sheet material.  Lengths of cord are drawn from spools and led in parallel relationship into a bath containing a solution of latex and resorcinal-formaldehyde and then into a heated bed of fluidised solid material to dry the cords.  The latter are rubberised in a calender to form rubberised fabric strip which is then trimmed at the edges thereof and wound on to the drums.  The bias angle of the cords in the cut lengths of material is about 61 degrees.  In a similar manner, a tubular length is made from unvulcanised rubber strip and cut into tubular lengths for the manufacture of inner tubes. Specification 885,513 is referred to.
Patent GB-651996-A (GB)
Title: Improved method of bonding aluminium or aluminium alloys to ferrous metals
IPC: C23C6/00
Filed: 1948-04-28
Abstract: 651,996. Casting composite articles. GENERAL MOTORS CORPORATION. April 28, 1948, No. 11639. Convention date, June 19, 1947. [Class 83 (i)] [Also in Group II] Composite articles are formed by acidetching a ferrous-metal member, coating the etched member by immersing it in a bath of molten zinc-base alloy containing small amounts of tin and aluminium until it reaches a temperature at least equal to the melting temperature of the alloy, placing the member in a mould while the alloy is still molten, and then casting molten aluminium or aluminium alloy around the member. A gear blank of aluminium alloy is formed with a steel hub 10 by washing or sand-blasting the hub before immersing it for a time ranging between five and ten minutes in concentrated hydrochloric acid (22‹ BaumÚ) which is at a temperature between 90‹ and 100‹ F. The hub 10 is then washed in a bath of hot water for a minimum time of two minutes after which it may be immersed in a bath of flux comprising 10 per cent zinc ammonium chloride at a temperature of 150‹ F. before being dried by an air stream and coated with the bonding alloy which is at a temperature of between 1300‹ and 1420‹ F. Any excess of coating alloy is removed from the hub 10 by scraping or shaping it before placing it in a mould or die made of metal, green or dry sand, or plaster. The hub 10 is then located on a part 32 of the mould which has a part 28 thereof pre-heated to a temperature between 400‹ and 500‹ F. Molten aluminium alloy at a temperature of about 1380‹ to 1420‹ F. is fed from a container 36 in the top part 34 of the mould, through passages 38 into a space 40 between the parts 28 and 34 of the mould where it is bonded to the hub 10 to form the gear blank. A steel for the hub 10 containing 1.0 to 1.3 per cent manganese, and 0.08 to 0.13 per cent sulphur satisfactorily bonds to an aluminium alloy comprising 3.5 to 45 per cent copper, 1.7 to 2.3 per cent nickel, 1.2 to 1.8 per cent magnesium, and a balance of aluminium, with the bonding alloy comprising 10 per cent tin, 0.4 per cent aluminium, and the balance zinc.

IPC: D03D51/00
Filed: 1929-04-15
Abstract: 309,917. Lenzkes, K. April 17, 1928, [Convention date]. Stop-motions, weft; reversing and stopping arrangements.-when the weft fails, a weft guard, or centre weft fork, causes a three-position switch controlling an electric motor for driving the loom to be moved rapidly by spring action from forward to reverse position, spring-controlled devices then causing the switch to rebound into position for interrupting the current and holding it locked in that position. When the welt fails, the weft guard b, Fig. 1, falls and causes a projection e to be moved into position to engage and turn an arm f on a shaft g having a second arm h in engagement with a rod i connected to a lever m, Fig. 3, which is thereby turned to cause the starting handle p to be moved out of its retainining notch and to move in a slot n by spring action into the position shown in Fig. 4. The handle p then rebounds by spring action. and a spring u causes the lever m to turn into the position shown in Fig. 3, so that a projection X thereon blocks the handle from again moving into the position shown in Fig. 4. The handle is linked to the three-position switch which is in the forward driving position when the handle is in the position shown in Fig. 3. When the handle moves into the position shown in Fig. 4, the switch is in position for reversing the motor and, after the rebound of the handle, the switch is moved into the central position for interrupting the current. When it is desired to run the loom backwards, the lever m is held by hand against the action of the spring u and the handle p is held in the position shown in Fig. 4.

Filed: 1951-05-18
Abstract: 705,290. Machines for moulding hollow blocks of concrete &c. SVENSKA AKTIEBOLAGET TELL. May 18, 1951 [May 26, 1950], No. 11690/51. Class 87 (2) Material is filled into a mould 1, which may be provided with cores, mounted in a frame 2 fixedly supported on guides 3. A box is provided on the frame 2 to facilitate the filling of the mould. The mould is then vibrated, e.g. by out of balance rotary discs 22, to compact the material. A shaft 14 is then rotated to cause pinions 13 to draw bars 8 downwards. Plates 4 fixed to a sliding beam 6 are moved down with the bars 8, and when the lower edges 27 of the plates 4 engage. the top of the material adjustable stops 26 on the bars 8 engage lobes 24 on a lower sliding beam 7 which carries the mould bottom 5. Further movement of the bars 8 now causes the bottom 5 to be lowered against springs 12 while the plates 4 press the moulded block out of the mould. As the block leaves the mould, an arm on the shaft 14 engages a loop' 19 on the beam 7 to pull the beam down and separate the top of the block from the plates 4. An abutment on an adjustable member 25 trips a switch to cut off the motor driving the'shaft 14. The moulded block is then removed on transverse rails. Additional stops on the bars 8 may control the vibrating mechanism.
