Title: Improvements in or relating to carrier wave signalling systems
IPC: H04B3/00
Filed: 1937-10-12
Abstract: 503,677. Multiplex signalling. STANDARD TELEPHONES & CABLES, Ltd., and JACOBSEN, B. B. Oct. 12, 1937, No. 27706. [Class 40 (iv)] In a multiplex carrier-wave system using separate conductors for the two directions of transmission, an additional signalling circuit which may be a low-frequency chan nel or a phantom cir cuit is transferred fron one two-wire line or one pair of two-wire lines to another at each repeater point or at intervals of twc or more repeaters. This reduces the interference on any one circuit and also increases the attenuation in the singing paths of the main repeaters. The transfer may be between lines carrying messages in the same direction as shown in Fig. 4 for a low-frequency channel, or between lines carrying messages in opposite directions as in Fig. 6, in which the two branches of a phantom circuit are separately led through inductance coils Z1, Z2 (which may serve to load the phantom circuit) from the inputs of the amplifiers of lines A1, A2 for one direction to the inputs of the amplifiers of the corresponding lines B1, B2 for the other direction. Transfers may be made between low-level points in both circuits as shown in Fig. 6, and between high-level points in both circuits alternately, and repeaters for the additional circuits are preferably only provided at transfers between high-level points. If two or more phantom circuits are provided in one system, they may be balanced by capacities connected between centre-tapped transformers bridging the side circuits. The additional circuits may be employed for the supervision of unattended repeaters.

Abstract: 776,792. Snap-action switches. SANTON, Ltd. Sept. 21, 1955 [Sept. 27, 1954], No. 27778/54. Class 38(5) A rotary switch in which a handle 7 drives a main hollow contactcarrying spindle 3 through an operating ' spring (not shown), a locking spring locking the spindle until the operating spring is sufficiently stressed, has an auxiliary spindle 4 rotatable within the spindle 3 and driven directly by the handle 7-through a rigid connection 5, 6.

Abstract: 380,268. Door latches. COOKLIN, L., 2, Lennox Avenue, New Brighton, Cheshire. Oct. 8, 1931, No. 27926. [Class 44.] A latch bolt 3 is slidably mounted in a guide 6 so as to engage a socket 4 in the ordinary way under action of a spring 7 when the door is closed, and the guide is pivotally mounted at 8 so that bolt and guide swing on the pivot to allow the door to be pulled open. A spring 14 acting on an arm 10 of the guide retains the guide in its normal position. The device thus acts as a yielding door catch. Means are provided to prevent pivotal movement of the guide when desired. The arm 10 normally moves along the longitudinal portion 12 of a bayonet slot formed in a rotatable sleeve 13, pivotal movement of the guide being prevented by rotating the sleeve to engage arm 10 in the circumferential portion 17 of the slot. The sleeve may be rotated by a removable key 16 or by a handle mounted on the door. A modi. fication, Fig. 4, comprises stamped casings 19, 20 secured to the door &c. and a catch 29 slidably mounted and biased by a spring 26 in a casing 27 pivotally carried by one arm of a spring 28 secured by a rivet 25.

Title: Improvements in windscreens for motor-driven vehicles
IPC: B60J1/00
Filed: 1924-11-24
Abstract: 237,781. Coward, C. Nov. 24, 1924. Windscreens.-Relates to windscreens, particularly for the rear seats of motor-vehicles, of the kind in which the screen is supported at each side of the vehicle by means of a self-locking linkage comprising two parallel arms 9, 11 pivoted to the back of the front seat or a similar support, and a third arm 10 pivoted to each of the arms 9, 11. According to the invention, the screen is mounted upon pillars 1 on a two-armed lever pivoted at 13 to the arm 10 and having one arm 15 pivoted to a link 18 connected to a second lever 16, which is in turn pivoted on the lower arm 11 and has a notch adapted to engage a stud 17 on the upper arm 9. In the erected position of the screen, the rear end of the lower arm 11 abuts against the under side of the upper arm 9, and the series of pivots 13, 15<1>, 16<1> and 9', 12, 8<1> are arranged in toggle formation. the toggles being broken and the notched lever 16 being disengaged from the stud 17 by folding the screen and pillars 1 forwardly as shown in Fig. 2, the screen finally assuming a substantially vertical folded position in advance of the folded linkage. In order to permit of lateral displacement of the screen, the latter is revolubly mounted on the pillars 1, and the arms 9, 11 are attached to lugs 7, 8 on a socket 3 revoluble on the main support 4. Sidescreens may also be pivoted on the pillars 1 and formed at their lower corners with segmental projections 21, which can be turned until they engage projections 22 on the arms 10 and thus lock the screen in its erected position so that the linkage cannot be folded until the side-screens have themselves been folded on to the main screen.

Abstract: 674,619. Rolling. LOEWY ENGINEERING CO., Ltd. Nov. 17, 1950, No. 28150/50. Class 83 (iv). [Also in Groups XXIV and XXXIV] A lubricating attachment for a rolling mill coupling-spindle 10, seated on the spindle itself, comprises rotating and non-rotating elements 26-28 in surface contact, a fluid-tight chamber 29 enclosed by said elements and situated at the end of a non-rotating element 27, passage ways 21, 31, 33, for feeding lubricant from an external line of supply to said chamber and from there into the spindle-head 13, and labyrinth seals extending along the surfaces of contact between the rotating and non- rotating elements. The elements 26-28 are formed along their contacting faces with complementary collars and grooves to form labyrinth seals preventing leakage from the chamber 29, channels 35 providing lubricant to all contact faces between the elements. The rotating elements 26, 28 are bolted to the spindle head 13 by bolts 43, while the intermediate element 27 is held against rotation by being pivotally attached to brackets 44, slidable by means of tubes 45 on a frame 46 common to both spindles 10 of a two-high mill, thus enabling the elements 27 of both spindles to follow freely angular displacement of the spindles 10 and align themselves with the associated members 26, 28 without jamming. Each element is made in at least two parts for assembly purposes, Fig. 3A, indicating the manner in which half rings making up the element 27 may be joined by bolts 39 estending through bores 38 along the split of the half rings, the bolts carrying nuts 40 which fit over bosses 41 on the half rings. The element 26 may be similarly assembled while the element 28 may be provided with flanges 42 through which bolts pass. The bore 32 is connected by a flexible connection to the external lubricant supply.
