Title: Application of frequency dividers to the reception of signal modulated electric carrier waves
IPC: H03D3/00
Filed: 1942-06-02
Abstract: 554,914. Wireless receiving systems. STANDARD TELEPHONES & CABLES, Ltd. June 2, 1942, No. 7456. Convention date, April 24, 1941. Drawings to Specification. [Class 40 (v)] A signal-modulated carrier wave is subdivided in frequency by a regenerative modulator circuit before passing to the signal detector. If the carrier is modulated in amplitude, the side-bands maintain their frequency separation from the carrier. If the carrier is frequency modulated, the frequency deviation is reduced to the same extent as the carrier frequency, so that the discriminator operates over a reduced frequency range and distortion is reduced. The Specification states that a weak interfering wave of frequency adjacent to the desired carrier can be regarded as an amplitude modulation on that carrier. When the combination is reduced in frequency, the undesired wave maintains the same frequency separation from the desired carrier, and may be more readily separated by filters. A suitable form of frequency-dividing circuit is described in U.S.A. Specification 2,159,595.

Filed: 1942-06-02
Abstract: 555,627. Hooks. SIGNALNESS, A. June 2, 1942, No. 7505. [Class 89 (ii)] Cargo sling hooks have means to prevent them from sliding down the sling during application to the load. One end of a sling 14 has an eye for engaging the hoisting hook and the sling passes through an eye 18 in a flat base 19 having a hook in the same plane as the base for engaging the eye at the other end of the sling. A projection 20 offset from the eye 18 has an inturned end to engage the sling and the eye 18 is flared at 20. When the sling engages the projection as shown in Fig. 2 the resulting distortion of the rope holds the hook in place. When it is desired to adjust the position of the hook on the sling, the rope is disengaged from the projection 20 and allowed to pass freely on the other side thereof. In a modification the base of the hook 17 is extended to form a socket flared at each end and through which the rope passes in the plane of the hook, a further extension at one side carrying the projection 20, and in a further modification the hook 40, Fig. 9, is pivoted in a bail having two sides 42 extending from a cross piece 43 and the projection 48 is formed on the back of the hook.

Title: Improvements in electrical resistor devices or thermistors
IPC: H01C7/04
Filed: 1946-03-13
Abstract: 615,988. Temperature-variable resistances; non-metal resistances; cooling resistances. TOMLINS, F. C. (Western Electric Co., Inc.). March 13, 1946; No. 7834. [Class 37] A thermistor is surrounded by material having high thermal capacity and conductivity in order that it should be able to more closely follow changes in applied power. In the thermistor assembly shown in Fig. 1, a receptacle 16, such as a glass vial, contains a thinwalled insulating tube 14 and mercury 22 as a filling material which therefore surrounds a thermistor bead 10 inserted within,the tube 14. The thermistor lead 11 may be extended for connection to the external circuit or may be welded within the tube 14 to an outgoing lead 13 made of material having a thermal expansion coefficient equal as far as possible to that of the tube 14, for example the tube 14 may be of glass and the lead 13 an alloy of copper, nickel and iron; the mercury 22 acts as a conductor connecting the other thermistor lead 12 to the other outgoing lead 17. Alcohol, glycerine, oil or amixture of oil and sand may be used instead of the mercury 22, in which case the tube 14 is omitted and leads 11, 12 extended. The surrounding material may be a block of copper 30 in which the tube 14 is inserted-Fig. 2-and secured by means of metallic binding 32 such as Wood's metal or dental amalgam; in this construction the tube 14 is externally coated with a material of high thermal conductivity such as silver adjacent the bead 10 as shown at 18, Fig. 3. A modification to Fig. 2 may be made similarly to Fig. 1, in that insulating material such as aluminium oxide may supersede the copper 30. The thermistor lead assembly may be modified to include three or more leads from the bead 10, Figs. 4 and 5 (not shown). The Specification includes typical characteristic curves, Fig. 6 (not shown), for a negative temperaturacoefficient thermistor and points out that if the latter is constructed according to the invention the existence of surrounding material (as described above) does mean a shorter heating and cooling cycle in comparison with a thermistor enclosed in an evacuated envelope.

Abstract: 121,903. Milde, G. S., and Textilite Engineering Co. May 22, 1913. Roller heads stopmotions; moistening paper strips in spinning &c. machines. In a machine of the type in which a paper strip is passed over a moistening-roller and between drawing-rollers to a flyer or spindle, the moistening - roller is positively driven at an adjustable speed and the strip is lifted from it automatically when the ribbon breaks or when the machine is stopped, or by an arrangement under the control of the operative. The drawing- rollers c<5>, c<6> are carried in a pivoted frame c and are driven by a roller d<1> mounted in a fixed bracket. The moistening-roller g<1> is driven from the shaft of the roller d<1> through change-gearing. The frame e is held in an upright position by a lug p<2> on a lever p engaging behind a lug e<7> on the frame. The paper strip passes through a guide w on the lever p over a wire guide h<1> carried on the frame e, over the moistening-roller and the drawing-rollers, and through a guide m<1> on a pivoted lever m to the flyers, &c. When the strip breaks, the lever m, which is weighted, moves on its pivot m<2> and carries a pawl m<6> on an arm m<4> into the path of an oscillating finger s<1>. This drags down a second arm m<5> into engagement with a projection p<3> on the lever p and releases the frame e which falls forward and lifts' the wire guide h<1> to lift the strip from the moistening- roller. The frame e by its movement operates the ordinary stop-motion through the link t. The wire guides h' can be raised by flaps on a shaft running along the front edge of the water trough f. This shaft carries a wheel 4 which has connected to it a weighted chain 6 and a chain 5 attached to a pulley 5<a>.

Abstract: 585,992. Magnetic induction accelerators. BRITISH THOMSON-HOUSTON CO., Ltd. June 2, 1943, No. 8879. Convention date, June 2, 1942. [Class 39 (i)] The orbit-expanding coils of a magnetic induction accelerator comprise two sets of coils 92, 93 and 94, 95. Each set of coils is oppositely energized so as to produce a neutral point in the orbital plane, and pairs of coils 93, 95 and 92, 94 are differentially connected so as to be non-inductive in relation to the main field. A circuit for energizing the coils at the appropriate time in the cycle may comprise a gas discharge relay controlled, through a phase shifter, by a pick-up coil in inductive relation to the main field. The expanded beam may strike an X-ray target, such as a portion of the injector cathode 86, or may pass into a deflecting magnet 100 which straightens the beam and permits it to pass out of the evacuated chamber 80 through a thin window. The magnet 100, Fig. 8, has two polepieces 102, 103 energized by coil 104 and bridged by a conductive shield 110 which serves to screen the magnet from the main alternating field and prevent distortion of the main field. The lead to cathode 86 is provided with a conductive screen 89.
