Title: Improved skin grafting knife
Inventor: CLARK BERNARD
IPC: A61B17/322
Filed: 1970-02-09
Abstract: 1275371 Skin grafting knife CHAS F THACKRAY Ltd 19 April 1971 [9 Feb 1970] 6086/70 Heading A5R A skin grafting knife with a handle comprises a holder composed of two parts 2 and 3, which are hinged together, for a removable blade, means for retaining the parts in a closed position, a carrier-bar extending from the handle parallel with the holder, a guide member carried by said bar in a parallel relationship so that the bar can rotate and turn the guide member in an arc about the bar. The two parts 2 and 3 of the holder are hinged together at the front edge about end-lugs 4 and 5, and the rear edge 8 of the upper part is curled around a bar 7 for which it provides a bearing so that the bar may rotate within the curled part. The guide rod 26 is rigidly attached to the bar by means of cross pieces. The blade is fitted to the upper part 2 by means of locating means 23, and retaining means 16-17, serve to secure the two parts 2 and 3 in a closed position. The retaining means are formed integrally with a thin bar 15 which is inserted between the bar 7 and the rear edge 8 of the upper part 2. The bar 15 is spring-loaded and can be moved longitudinally by a trigger 20 in order that the projections 17 be locked in corresponding slots in the lower part 3. A lug 40 attached to bar 7 is threadedly located around a screw 39 from which a projection 37 on a resilient pad 38 abuts a cam surface 36, rotation of which thus imparts a moment to the bar 7 through the lug 40 and causes the bar to rotate. The cam surface is rotated around a pin 41 by a lever 31, which is spring-loaded to turn at right angles to the plane of rotation of the cam and lock the cam in position by engaging grooves 43 on an attachment 11 of the handle.

Title: Improvements in pie or like filling machines
IPC: A21C15/00
Filed: 1935-02-26
Abstract: 452,514. Filling pies &c. CHRISTIANSEN, E., and ERICSSON, C. O., Food Machinery Works, Lifford Lane, Kings Norton, Birmingham. Feb. 26, 1935, No. 6098. [Class 28 (i)] A pie or like filling-machine comprises a discharge reservoir 5 to which liquid filling material is intermittently supplied from a main reservoir 6 and from which the liquid is released to fill a pie casing or the like by an intermittently operated valve 11. The pie casings may be in moulds 2 on an intermittently rotating table 1 and may be moulded by a tool 3 and then brought under the reservoir 5. The filling liquid is discharged from the main reservoir 6 to an upwardly-inclined conduit 4 entering the reservoir 5 below an outlet formed by a central tube 9. The valve 11 comprises a horizontal sleeve having a valve opening 13 and a stem 14 and is operated by a lever 15. The liquid is discharged through a neck 10a to a nozzle 20 which may comprise a cluster of tubes 21. A space 22 may be provided to allow the liquid to be equally distributed among the tubes 21. The lever 15 carries a pin engaging a slot in one end of a weighted lever 16 pivoted at its other end on the conduit 4. The lever 16 is raised by a bent arm 18 mounted on a reciprocating slide of the tool 3. The arrangement is such that the valve is opened while the tool 3 is descending and remains open for a limited period. The feeding of liquid is thus accurately timed and splash and drip are avoided.

Abstract: 1357250 Knitting machines EDOUARD DUBIED & CIE SA 9 Feb 1972 [10 March 1971] 6134/72 Heading D1C [Also in Division G3] A carriage position measuring device of a programme controlled flatbed knitting machine comprises reading systems 1, 2 cooperating with, and mutually spaced by a quarter of the pitch of, grooves 3 in the auxiliary needle bed 4 guiding the jacks cooperating with the needles each reading system comprising a pair 5, 6 of reading combs mutually offset by half the pitch of grooves 3, forming, along with fixed capacitor (12) and variable capacitor (13), Fig. 4 (not shown) a capacitance bridge fed by oscillator 14, the output being a modulated waveform (U9), Fig. 5 (not shown), whose amplitude varies periodically as a function of carriage position. The waveform from each reading system is processed in respective multipliers and phase discriminators 18 demodulators 20, and square wave generators 23 to provide to coincidence memory 29, also receiving programme information from unit 27, a pair 26 of square waves in quadrature, the memory controlling the machine 28 to obtain coincidence between position and programme command signals. A needle counting and carriage direction detection system 30 is also provided. The oscillator frequency is substantially higher than the greatest moulding frequency attained in practice. By using a multiplicity of elements 7, 8, whose pitch equals that of grooves 3, in each reading system, greater accuracy is attained. Allowance may be made in the programme for any delay in machine response due to inertia. The circuitry of Fig. 1 is detailed in Fig. 3 (not shown).

Abstract: 622,047. Automatic couplings. A.B.C. COUPLER & ENGINEERING CO., Ltd., COSSEY, J. C. G., and SMITH, G. H. March 6, 1947, No. 6355. [Class 103 (v)] An automatic coupling of the type described in Specification 595,968 comprises coupler heads b<SP>1</SP> and b<SP>2</SP> on the vehicles, a single connecting pin a, and locking pins d, the inverted U. shaped lower parts of which engage each end of the connecting pin a. When two vehicles are to be coupled, the locking pin d on the coupler head not fitted with the connecting pin a, is raised manually so that the projection e<SP>1</SP> of its pivoted latch e is seated upon the ledges f<SP>2</SP> formed at each side of the opening in the top of the coupler head, as shown dotted in Fig. 4. When the enlarged end a<SP>1</SP> of the connecting pin a enters the coupler head, it bears against the lower end of the latch, so that the projection e<SP>1</SP> is moved off the ledges f<SP>2</SP> and comes over the enlarged part of the opening f<SP>1</SP> and thus enables the locking pin to drop and engage the recessed part a<SP>4</SP> of the connecting pin a with the top of inverted U-shape recess. To unlock the coupling, the locking pin d is raised by its handle d<SP>2</SP> so that the projection e' seats again on the ledges J<SP>2</SP> and the pin a may be withdrawn through the inverted U-shape recess. Lock members g pivoted on the coupler heads may be used both to hold the locking pins d in the ready for coupling position and to retain them in position when the vehicle is emptied by being inverted around the axis of the coupling pin without decoupling.

Title: Process for the preparation of cumene hydroperoxide
IPC: C07C409/10
Filed: 1952-03-12
Abstract: Cumene hydroperoxide is prepared by oxidizing cumene with molecular oxygen or a gas containing molecular oxygen in the presence of benzoic acid.  Suitably the reaction is carried out by oxidizing with air in the presence of about 0.5 gm. of benzoic acid per kilogram of cumene, the reaction being initiated by the addition of a small proportion of cumene hydroperoxide.  The benzoic acid may conveniently be added in portions during the course of the reaction. Examples describe the oxidation of cumene to cumene hydroperoxide at 110 DEG  C. in the presence of benzoic acid by means of air and oxygen.
