Title: Improvements in artificial hands
IPC: A61F2/58
Filed: 1929-02-26
Abstract: 326,970. Levasseur, J. W. Feb. 26, 1929. Limbs, artificial.-An artificial hand is characterized by fixed fingers and a pivoted thumb, the latter being normally held in the closed position by means of elastic bands which also serve as flexible gripping surfaces between 1st finger and thumb. The base of the thumb is connected by a strip of leather or like material to the smaller rim of a double-diameter pulley situated transversely within the hand-frame, and a further leather strip, operating on the rim of the larger pulley is attached to the opposite arm of the wearer. Elastic bands are stretched along the inner side of each finger and the thumb in order that a better grip may be obtained on hard objects. Referring to Fig. 6, 45 is the pulley, 47 and 49 the leather operating strip, and 39 the elastic band which normally urges the thumb 33 to the closed gripping position. Another elastic band 40 is stretched between the tip of the first finger 26, over a pin in the bearing-frame 30, and back to the thumb at 34. A block 42 holds the inner elastic surfaces of the first finger and the thumb in contact so that small articles such as writing implements and the like may be held. The hand is rigidly attached to an arm-engaging section 16 which embraces the forearm as is shown in Fig. 5. The lower extremity of an upper-arm socket 15 is connected by means of the flexible strips 24 to the wrist end of the forearm socket 16. The whole is supported by a strap 53 which passes round the opposite shoulder of the wearer and is secured to the upper-arm section 15 by means of a clip 54.

Title: Improvements in heat-insulating material
IPC: C04B35/16
Filed: 1944-04-05
Abstract: A heat-insulating material of cellular structure is formed by the thermal reaction of an aqueous mixture of calcium oxide, silica and inorganic fibres together with a hydrophilic colloid which absorbs a large amount of water which on expulsion leaves cells or voids, and which is rendered substantially inert to reabsorption of water by reacting with calcium oxide.  In an example, a slurry is formed with 4 parts by weight of lime and 6 1/2 of silica, both preferably ground to pass a 140 mesh inch screen, together with 2 1/4 of uncalcined bentonite and 2 1/4 of graded asbestos in 85 of water and the mixture cooked at a temperature below 212 DEG F. till it attains a viscous consistency.  The mixture is then poured, extruded, or otherwise deposited into moulds and subjected to heat, and preferably to steam treatment in an autoclave and finally dried to give a product which may be used up to 1,000 DEG F.

Patent GB-645871-A (GB)
Title: Telecommunication exchange and system
IPC: H04Q11/04
Filed: 1947-03-07
Abstract: 645,871. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. March 7, 1947, No. 6463. Convention date, March 14, 1946. [Class 40 (iv)] In an electronic exchange system of the type described in Specification 644,571, two distributer tubes are used, one for transinission and one for reception of the speech signals, outgoing signals being applied to the grid of one, and incoming signals being used to modulate pulses produced on the anode of the other. In the speech transmission path moreover, two storage devices are provided one each for the calling and called subscriber's speech signals. Electronically controlled ringing is also provided. The subscriber's set is connected via hybrid 3 to electrodes in the transmitting and receiving distributers 5, 6 and when the subscriber lifts his hand-set both tubes are biassed to cause secondary emission current to flow when the electrodes are traversed by the beam. Tube 5 produces pulses 13 at time positions appropriate to the calling line and a line-finder, Fig. 2, is seized as described in Specification 644,571. Gate 44 passes pulses modulated by dialling impulses to the impulse receiving circuit, Fig. 4, the dial gate 65 of which passes the impulses to the registering chain 72 ... 77. The chain 84 ... 91 counts the electrodes passed by the distributer beams, opening whichever of the gates 78 ... 80 is prepared by the register at the time position of the called line, thereby applying a pulse to valve 49 which opens the input and output gates 45, 47 at this instant. Valves 67, 68, which change over at the beginning of the impulse train, restore at the end to change over valves 102, 103 to open the ringing gate 104 which passes ringing current to the output gate 47. Valve 67 also changes over 69, 70 which closes the dial gate 65 and opens the speech transmission gate 108. When the called subscriber answers, pulses are produced on wire 113 coincident with those derived from the appropriate one of the gates 78 ... 80, this coincidence causing ring trip valve 114 to conduct, the resulting pulse restoring 102, 103 to close the ringing gate 104. With gates 44, 46 being opened by pulses from the line-finder at the calling subscriber's time position and gates 45 and 47 being opened by pulses from the register circuit at the called subscriber's time position, pulses modulated by the calling and called subscriber's speech pass from the anode of the receiving distributer to the grid of the transmitting distributer via storage filters 117, 118 respectively. When the calling subscriber hangs up a restoring pulse for the register and valves 69, 70 is derived from the line-finder over wire 124.

The twisted tubes may be inserted into a sleeve 6, which may also be of extruded thermoformable plastics material, such as polyvinyl chloride, before forming the coil. Alternatively, the sleeve may longitudinally slit to receive tubes and wires. The tube ends are provided with unions 4 and nylon collars 5. The retracted coil form may be of any desired shape, such as cylindrical, tapered, double-tapered, or flat.
