Abstract: 1,187,725. Sewing-machines. JAMES CASH MACHINE CO. 25 Sept., 1968 [2 Oct., 1967], No. 45620/68 Heading D1G. In a sewing machine a presser foot is adjustably driven to produce either a long stroke with high bottom elevation or a short stroke with low bottom elevation for thick or thin fabrics. The presser bar 6 is reciprocated by an arm 8 on a rock shaft 9 which is rotated by a rock arm lever 10 connected to a pitman 11 driven from an eccentric 12 on a shaft 2. The connection between the pitman 11 and rock arm lever 10 is adjustable by means of a screw 18. As the screw 18 is adjusted so the rock arm lever 10 is displaced to vary the bottom elevation of the presser foot and the position of the connection to the pitman alters the angular reciprocation of the rock arm lever and hence the stroke of the presser foot.

Title: Improvements in or relating to apparatus for and methods of false-twist-crimping of yarn
Inventor: MATTINGLY DENIS ALBERT EDWARD
IPC: D02G1/02
Filed: 1962-12-03
Abstract: In a multiple assembly of false-twist crimping units on a machine, vertical height is saved in the heat-setting zone by provision of oblique, e.g. V, zig-zag or straight, yarn paths across a narrow, elongated, convex, fluid-heated surface.  The paths are defined by grooves extending across the surface or by guides on each side of and below the surface (augmented, perhaps, by guides intermediate the longitudinal horizontal edges thereof) whereby the tension in the yarns maintains them in contact with the surface and the obliquity may be varied according to the choice of guides.  The yarns may pass twice across the same heating surface.

Title: Method and a device for coalescing the disperse phase of an emulsion
IPC: B01D17/04
Filed: 1973-10-01
Abstract: 1410694 Coalescing emulsions ALFA LAVAL AB 1 Oct 1973 [9 Oct 1972] 45800/73 Heading BID The disperse phase of an emulsion is coalesced by passing the emulsion vertically through a bed 8 of individual bodies which are more wettable by the disperse phase than by the continuous phase, the bed being located in a space 6 which is completely filled with flowing emulsion and which is greater than that required by the bed alone such as to permit relative movement between the individual bodies during flow of the emulsion and the emulsion being passed at a rate sufficient to maintain the bed close to the outlet due to the flow force of the emulsion. Suitably the specific gravity of the bodies is chosen such that they tend to move in a direction opposite to the flow direction. The bed is located between two perforated restraining walls 4, 5, e.g. nets. The bed both coalesces and collects sludge particles which may be flushed out after stopping emulsion flow by forward or reverse flow of water. The use of metal-cored plastics bodies for the coalescing of oil-in-water emulsion, e.g. from ships bilges, is described. The coalesced oil is subsequently separated from the water.

Title: Improvements to selection circuits for memory lines

Abstract: 1,129,025. Circuits employing bi-stable magnetic elements; superconductor circuits. OLIVETTI GENERAL ELECTRIC S.p.A. 3 Nov., 1966 [3 Nov., 1965], No. 49401/66. Heading H3B. Each end of a line of a memory is connected to a pair of oppositely poled diodes and is resistively connected to a voltage source so as to suppress stray current transients due to the capacity of non-selected lines when one of the lines is selected for sending pulses therethrough. A memory matrix comprises a plurality of lines 1,2 . . . 101, 102 each linking a plurality of magnetic cores, thin film storage elements or cryogenic memories and each line being connected at each end to unidirectional switches 7, 8, 107, 108 and 13, 14, 15, 16, as shown. When line 1 is selected for reading switches 7, 13 are closed and the read pulse from generator GI flows through switch 7, diodes 3, 9 and switch 13. Since line 2 is biased by generator +V diodes 5, 12 are reverse biased and diode 5 prevents the read pulse from entering line 2. Following the read pulse switches 7, 13 are opened and switches 14, 8 are closed and a write pulse from generator GS flows through switch 14, diodes 10, 4 and switch 8 to earth. Since non-selected line 101 is held at a voltage +V diodes 103, 110 are reverse biased and the write pulse is prevented from entering line 101 and unwanted transients caused by the capacity of the non-selected lines is suppressed. Fig. 3 shows an arrangement in accordance with the invention in which the number of unidirectional switches used is reduced, only one line being shown. Transistor 17 corresponds to switch 8 of Fig. 2 and transistor 18 to switch 13. To send a read pulse on line 1, transistors 18, 23 are made conductive and the reverse bias on diode 3 is removed. Then read pulse generator GI sends a pulse through the circuit comprising primary winding 21, diode 22, transistor 23 and earth so inducing a read pulse in secondary 20 line 1, diodes 3, 9 and transistor 18. Similarly a write pulse is sent along line 1 by first making transistors 7, 23 conductive to remove the reverse bias from diode 10 and passing a pulse from write generator GS through primary winding 26 to induce a write pulse in secondary 25. In the arrangement of Fig. 4 (not shown), a common read/write pulse generator is used using two separate transistor switches which are each connected to one end of a primary winding of Fig. 3.
