Title: Improvements relating to artificial silk
IPC: D06M13/148
Filed: 1934-05-11
Abstract: Artificial silk yarn or fabric is loaded by impregnating with synthetic resin components and with one or more water soluble organic compounds of high boiling point and high specific gravity, the material being heated to insolubilize the resin and fix the loading agent.  Preferred resins are of the formaldehyde-urea type; suitable loading agents are polyhydric alcohols, their polymers or water-soluble derivatives, or mixtures thereof, e.g. glycerol, diethylene glycol, mono-chlorhydrin, mono-, di- and triacetin.  The material is treated with the loading agent together with formaldehyde and urea or thiourea, or an early intermediate condensation product, and a catalyst; the material is subsequently heated to 180--210 DEG C. for 30--60 seconds.  In an example, a viscose cr<\>zepe thread is impregnated with its own weight of a mixture of a urea-formaldehyde condensate, lactic acid and diethylene glycol, dried, heated to 200 DEG  C. for 50 seconds and washed in slightly alkaline water; after drying, the fabric has gained in weight by 20 per cent.

Title: Suspension railway
IPC: B61B12/02
Filed: 1959-04-27
Abstract: 918,203. Locomotives. SAFEGE-TRANSPORT. April 27, 1959 [March 10, 1959], No. 14331/59. Classes 79(1) and 79(3). [Also in Group XXXII] A railway vehicle body 23, Figs. 2 and 3, is suspended by hangers 51 from a pair of bogie-trucks, running within an overhead box-section girder 20, so that the body is rotatable, under the action of transverse forces, about an axis extending parallel to the girder 20 and situated above the trucks. Each truck comprises a frame 42 carrying a pair of axles 44 for wheels 35 and driven from electric motors 47 through reduction gears 45, the wheels 35 engaging tracks 33, 34 in the girder which is slotted. The motors are supplied with electricity from rails 50 carried by the roof 27 of the girder, through current collectors 49 urged by springs 46 against the rails 50. Guide wheels 40 mounted on the frame 42 engage with the sides 25, 26 of the girder. The hanger 51 is mounted in the manner of a pendulum on a pair of pneumatic springs 102, 103, carried by the frame 42, and projects downwardly through the slot between the tracks 33, 34. Pivoted to the hanger 51 on a pin 104 is a transverse fork member 105, Fig. 5, each end of which carries an inclined stub shaft 106 (see also Fig. 3) carrying an arm 107 connected at its other end to a stub shaft 101 parallel to the shaft 106 and carried by the top of the body 23. The arrangement is such that the plane containing the longitudinal axes of the shaft 106 meets the vertical axis of the device 51 above the truck. At one or both sides of the body 23 the arms 107 are formed integral with cranks 111 connected by rods 108, in each of which is interposed a piston 109 movable in a cylinder 110 secured to the body 23 and filled with hydraulic liquid. By controlling movement of the piston in the cylinder the transverse equilibrium of the body may likewise be controlled. The air supply for the springs 102, 103 may be controlled at will or automatically. In another embodiment described with reference to Figs. 6 and 7 (not shown) the fork member is connected to the roof of the vehicle body through Watt parallel motion linkages. Specification 741,830 is referred to.

Title: Improvements in or relating to valves particularly steam distribution valves
Inventor: THOMPSON CHARLES CLINTON
IPC: F01L15/10
Filed: 1952-06-09
Abstract: 710,744. Engine distributing valves. SPENCE ENGINEERING CO., Inc. June 9, 1952, No. 14460/52. Class 122(2) The exhaust period of a steam engine having an inside steam pistou distributing valve 5 is prolonged by means of a radial port or ports located in the valve packing distance ring 16 between the valve inlet and exhaust edges and controlled by a sleeve valve 22 axially slidable with respect to the piston valve, the sleeve valve being resiliently urged to open the ports and acted upon by the cylinder compression to close the ports. The distance ring 16 surrounds the valve spider 15 and carries at each of its ends packing rings 17, 18 respectively controlling steam inlet and exhaust through the main cylinder steam port 9. The distance ring 16 and spider 15 have a plurality of aligned radial ports 19, 2Q respectively controlled by the sleeve valve 22 which is slidable in ari annular groove in the ring 16 and urged in a direction to open the ports by a plurality of springs 25. The end of the sleeve valve adjacent to the inlet packing ring 17 communicates with the outside of the distance ring through a series of radial ports 23. After main exhaust has been cut off by the exhaust packing ring 18 when the piston valve is moving to the right, exhaust still occurs through the ports 19, 20 and continues until port 19 passes the main cylinder port 9. Compression then begins in the main cylinder and just prior to admission is sufficient to overcome the springs 25 to thereby move the sleeve valve 22 and close the ports 19, 20; the valve 22 being maintained in the closed position during the working stroke by the steam pressure in the cylinder. When the port 9 is-again opened to exhaust by the exhaust packing ring clearing the edge of port 9 the pressure behind the sleeve valve is relieved and the valve moved by the springs 25 to open the ports 19, 20. For a double acting engine the other end of the piston valve is similarly arranged.

Abstract: 908,489. Electric selective signalling systems. STANDARD TELEPHONE & CABLES Ltd. (Nippon Electric Co. Ltd.). April 26, 1960, No. 14527/60. Class 40 (1). [Also in Group XL (c)] Pulses which are coded in a reflected binary code are supplied to terminal 1 and converted at 2 into a wave train consisting of positive pulses for binary " 1 " and negative pulses for binary "0." The resulting pulse train is supplied via an adding circuit 3 to an output gate 6 and to an amplifier 5, which doubles the pulse amplitude. The output of the amplifier 5 which is a pulse of positive or negative polarity is fed back via a one-digit delay line 4 and is added at 3 with the next digit pulse of positive or negative value. This operation is repeated n times where n is the number of binary digits and the gate 6 is opened to coincide with the nth digit to provide the decoded output at 7. The amplifier 5 may be replaced by an attenuator reducing the pulse amplitude by one half. Specification 663,872 is referred to.

Abstract: 672,927. Phase measurements. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 1, 1950 [June 2, 1949], No. 14796/49. Class 37. [Also in Group XL (c)] The phase of a signal voltage 8 is compared with that of a reference voltage 6, 7 by applying the signal voltage to the grid of a linear amplifier valve 1 which has as its anode load a parallel pair of valves 2, 3 each in series with a resistor 4, 5. The reference voltage is applied in pushpull at 6, 7 to the grids of the back-biased valves 2, 3 so that they are alternately unblocked for equal periods. The mean current passing through the valves 2, 3 is dependent on the phase of the signal voltage applied at 8, and the D.C. voltage across the terminals 9, 10 represents in magnitude and polarity the relative phase of the signal and reference voltages. The D.C. output voltage is also proportional to the amplitude of the signal voltage, and changes sign when the phase of the signal voltage is reversed. The terminals 9, 10 may be connected to a capacity-shunted meter, or to a push-pull D.C. amplifier, or to a cathodefollower. The voltages compared may be of frequency up to 1 mc/s.
