Abstract: 788,870. Knitting-machines. MONK (SUTTON IN ASHFIELD), Ltd., S. A. June 22, 1956 [June 23, 1955], No. 18136/55. Drawings to Specification. Class 74 (2). The locating plunger associated with each fashioning screw of a straight-bar machine operates a switch in the circuit of an electric lamp, the switch being opened when the plunger is in its operative position in which it registers with a recess in its associated disc, and closed to switch on the lamp when it is moved out of its recess. The switches for the plungers are arranged in parallel so that the lamp is switched on if any plunger is not registering correctly with its disc. A master switch may be included in the circuit which renders the switches inoperative during normal working of the machine and renders them operative only during the period in which the fashioning screws are being reset after finishing one garment and prior to the commencement of the next.

Title: A process for the production of organosiloxane polymers
IPC: C08G77/00
Filed: 1948-07-09
Abstract: Cyclic diorganosiloxanes are converted to higher polymers by reaction with an alkali metal salt of a triorganosilanol, prepared, for example, as in Specification 631,506.  The diorgano-siloxane is a dialkyl or an alkyl/arylaralkyl- or alkaryl-siloxane and the proportion of the metal salt of a triorganosilanol is preferably such as to give less than 1 atom of alkali metal per 25 atoms of silicon. The reaction temperature may extend from room temperatures up to 250 DEG  C.  A low proportion of alkali metal salt produces high polymers.  Polymerization may be terminated by adding a triorgano silicon halide, to give a halogen to alkali metal ratio of at least one so as to introduce chain terminating triorgano silyl groups, and removing the alkali metal halide.  In examples, the potassium salt of trimethyl silanol was reacted with (1), (2) and (3) octamethylcyclotetrasiloxane; (4) different cyclic dimethylsiloxanes; (5) the sodium salt of trimethylsilanol was reacted with hexamethylcyclotrisiloxane and with 1,2,3,4-tetramethyl, 1,2,3,4-tetraphenylcyclotetrasiloxane; (6) the sodium salts of (a) triphenylsilanol, (b) methyldiphenyl silanol, and (c) dimethylphenylsilanol were reacted with octamethylcyclotetrasiloxane; (7) the sodium salt of trimethyl silanol was reacted with a mixture of cyclic tetrasiloxanes.ALSO:In examples, the potassium and sodium salts of triorganosilanols are prepared by reacting (1), (2), (3), (4) potassium amide with hexamethyl-disiloxane; (5), (7) sodium amide with hexamethyldisiloxane; (6) NaOH with (a) triphenylsilanol; (b) dimethyltetraphenyl disiloxane; (c) diphenyltetramethyl disiloxane. Specification 631,506 is referred to.ALSO:In examples (1) to (5) potassium and sodium amides are prepared by the reaction of potassium and sodium with an excess of liquid ammonia in the presence of a trace of ferric nitrate nonahydrate.

Title: Fluid shock absorber
IPC: F16F9/26
Filed: 1935-06-29
Abstract: 458,809. Hydraulic shock absorbers. DEUTSCH, F. A., 1, Konstanzer Strasse, Berlin. June 29, 1935, No. 18703. [A Specification was laid open to inspection under Sect 91 of the Acts, Dec. 31, 1935.] [Class 108 (iii)] in an hydraulic shock-absorber of the reciprocating-piston type, the piston and cylinder form a self - contained shock - absorbing unit which is inserted into a housing forming a refill chamber communicating with the working chamber of the unit, one part, for example the piston, being fixed to the housing and carrying a device for regulating the escape of liquid from the working chamber. In the double-acting construction shown in Fig. 1, each piston 18 is fixed to a locknut 19 closing one end of the casing 1, and the sliding cylinder 11 is spring-pressed into contact with a pin 3 inserted in the operating shaft. A cup-leather 20 is pressed against the pistonface by a spring 21 which bears at its other end on. a radially and centrallybored de-aerating device 22 fixed on the piston-face and in communication with the other side of the piston through a conduit controlled by spring-separated ball-valves 23, 24, the main valve 24 being adjustably spring-pressed. The cylinder carries a. third spring-pressed relief valve 13. In operation, when the pin 3 moves anticlockwise into the position shown, the left-hand cylinder 11 slides to the right, fluid flowing through the valve 13 into the working chamber. On subsequent clockwise movement of the pin the fluid, together with any air, is forced by the cylinder through the radial bores 22a of the device 22, the central bore 22b, and past the valve 23, and when the pressure is sufficient, lifts the valve 24 and flows into the casing through a passage 31 and recess 32 in the piston. When the pressure ceases the ball 23 is first seated and the spring 23b silences the return movement of the ball 24 on the seat. Alternatively, the ball 23 may be dispensed with and the communicating channel leading to the valve 24 may be throttled or other means provided to silence the valve 24. A fluid-tight joint is formed where the end of the shaft 2 passes through the casing by means of an elastic ring deformed under spring-pressure to engage both the casing and a groove in the shaft. In a modification, Fig. 3, the ball-valve 24 is replaced by an adjustably spring-pressed, centrally-apertured, spherically-ended valve 33 with which cooperates a tapered pin 35, adjustable by a screw 36. Normally the fluid is throttled by the pin but on excessive pressure the valve 33 lifts and functions as a pressure-relief valve. A screen 37 may be inserted as shown to filter the fluid. Fig. 5 shows another construction of regulating valve in which the valve-carrier 25 is acted on bv weak and strong springs 26, 39 respectively, regulation of the spring 26 by a screw 27 enabling the valve 24 to be accurately adjusted. Shockabsorbers according to the invention when used on a vehicle may be interconnected in order to stabilize the vehicle. Specifications 364,308 and 392,202 are referred to.
