IPC: H01R33/46
Filed: 1933-05-23
Abstract: 419,612. Electric - lamp holders. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and PAYNE, F. W., Witton Moulded Insulation Works, Witton, Birmingham. May 23, 1933, No. 14887. [Class 39 (ii).] In electric-lamp holders of the bayonet type having a body of moulded insulating material, the skirt or socket of the lamp holder, or a part thereof, is formed from a tubular paper member and a synthetic resin arranged in a mould and moulded together with the composition for forming other parts of the body. Preferably the tubular paper member is formed as a hollow roll of paper with a varnish of synthetic resin included between adjacent layers thereof, the other parts of the body consisting of a phenol-formaldehyde synthetic resin and a filler. After the rolling, and during the moulding of the holder, the varnish is cured under heat and pressure to bind the laminations together. Preferably the synthetic resin used as the varnish is such that the curing time is substantially the same as that of the material of which the body of the lamp holder is composed. The main part of the insulating- body may be moulded with axial holes for contact pins and terminals, and a bridge piece formed with laterally extending guards separating the terminals, in addition to a central domelike clamping projection.

Abstract: 729,926. Reciprocating. electric motors. SMITH & SONS (ENGLAND), Ltd., S. June 15, 1953 [June 13, 1952], No. 14950/52. Class 35. [Also in Croup XVIII] A device maintained in operation by a spring which is intermittently wound by a solenoid and armature energized by a source of electricity, the winding action being initiated when the extension of the spring reaches a predetermined value, comprises a member acted upon and displaced by the armature upon energization of the solenoid and means to maintain the solenoid in an open-circuited condition should said displacement fail to exceed a predetermined amount. The invention is described as applied to clock in which the mainspring 17, Fig. 1, pulls the lever clockwise and the pawl 19 steps-on the ratchet 20 in the train. A contact 5 carried by the member 6 meets a contact 4 to close the circuit from a battery (not shown) to the solenoid 1. The armature 2 is thereby moved clockwise about its pivot 3 against the pressure of a spring 22 to return the lever 6 to its initial position. The end 10 of an L-shaped spring 9 carried by the lever 6 normally wipes past a fluid member 12. If, however, the E.M.F. of the battery falls below a minimum value and the impulse given to the armature 2 is insufficient fully to return the lever 6 the end 10 of the spring member 9 engages in the notch 15 of the member 12 so that the lever 6 is held in such a position that the contacts 4, 5 are open, Fig. 4 (not shown).

Abstract: 820,392. Creping paper &c. WALTON, R. R. May 14, 1957 [May 28, 1956], No. 15264/57. Class 96. In creping a web of paper &c. longitudinally and transversely so as to condense it widthwise and lengthwise, a web 16 is pulled, by a driven roller 50, firstly under a tensioning bar 18, then partly around a smooth downwardly curved rod 24 and then between a series of intermeshing tapered rollers 30 and 32 freely and rotatably mounted, respectively, on downwardly curved axles 26 and 28. The rod 24 and the axles 26 and 28 have substantially the same centre of curvature. The bearings of the axle 26 are pressed towards those of the axle 28 by springs 42. The web passes over the driven roller 50, preferably made of rubber, which is provided with circumferential grooves and ribs receiving the creped longitudinal undulations made in the web by the rollers 30 and 32. The web is pressed against the roller 50 by a shoe 62 comprising fingers or ridges fitting the grooves in the roller. The latter may have a plain deformable periphery in which grooves are transiently impressed by the fingers or ridges on the shoe. The web is removed from the roller 50 and transversely creped by a take-off comb 76, which may comprise a series of fingers or rotating takeoff wheels and which may be swung towards or away from the discharge end of the shoe. The axle 26 and rollers 30 may be omitted and the web may be fed to the rollers 32 or through a stack of similarly mounted rollers so that it makes contact with about half of their circumference. When transverse creping only is required, the web is drawn under a straight smooth bar 24a and over a similar bar 24b without passing between the rollers 30 and 32. The roller 50 then has a plain surface and the shoe is smooth. A web may be stretched lengthwise by removing it from the roller 50 by means of a rotating take-off comb having a peripheral speed exceeding that of the said roller. A web may be stretched widthwise by being passed through the longitudinal creping part of the apparatus in the opposite direction.

Abstract: 417,882. Bobbin drag arrangements. FRASER, G., FRASER, N., and FRASER, J., Westburn Foundry, Arbroath, Angus. May 27, 1933, Nos. 15359 and 25006. [Class 120 (ii).] A bobbin drag arrangement comprises a plurality of concentric rings, including a fixed inner drag ring surrounded by supplementary rings axially movable independently of one another into and out of engagement with a surface or surfaces rotatable with the bobbin. The fixed drag ring may be constituted by a flange on the bobbin spindle socket. The undersides of the movable rings may be formed with inclined surfaces engageable by projections on an annular base plate whereby relative angular movement of the rings and the base plate causes the rings to move axially. The bobbin 18 is carried on a platform 13 having a disc of felt or the like 14 on its under surface for engagement with the concentric drag rings 1, 2, 3, of which the inner ring 1 is fixed, and the outer rings 2, 3 are axially displaceable into contact with the friction surface 14. A bar 8 is provided with a pin 9 in engagement with each outer ring 3, so that displacement of the bar 8 rotates the ring 3 ; the under surface of rings 2 and 3 have inclined surfaces 7 which ride over ridges 6 in the base plate 5, so that such rotation axially displaces the ring 3 and applies drag. The ring 2 also participates in the rotational movement by means of a pin and slot mechanism (not shown), so that the rings are independently axially movable. The friction surface 14 may comprise rings of material having different coefficients of friction. Instead of the ridges 6 in the base plate 5, studs or buttons may be fixed thereto.

Abstract: 1,044,726. Transistor multi-stable circuits, SPERRY RAND CORPORATION. April 15. 1964 [April 23, 1963], No. 15627/64. Heading H3T. [Also in Division G4-G6] A stage of a non-synchronous bi-stable or multi-stable counter comprises three AND- inverter gates A, B, C used respectively as input, output and control sections. All the A stages are cross-coupled, as are all the B stages, while the outputs of the C stages are fed back to the inputs of the A stages. Before counting begins a preclear positive pulse sets all the B stages except one to set condition. Application of - ve potential to lead 18, Fig. 1, unlocks the first stage so that A and B<SP>1</SP> go +ve while B and C<SP>1</SP> gove. When lead 18 goes + ve again C goes + ve and A - ve so that a count of 1 is registered. The next count signal completes the cycle as shown in Fig. 2. A number of circuits may be put together in cascade, Fig. 3. If the circuits are alike as shown in full lines then with contact 54 in upper position the code operates as if binary subtraction were being performed. If, however, all the later circuits are modified, as shown in dashed lines, and contact 54 is put in lower position then the code is pure binary. Ring and gated counters, Fig. 6 (and Figs. 8a, 8b, not shown). Fig. 6 shows a ternary counter in which only one of the B sections has a + ve output, such being made to represent 1, i.e. the reverse of the situation in the binary counter of Fig. 1. If like circuits are put together to effect carry the second denomination always indicates one in advance of the normal code. This may be corrected by additional inputs to some of the A and C sections in the higher denominations and taking the output from B<SP>1</SP> instead of B (Figs. 8a, 8b, not shown) when a pure ternary code results.

Abstract: 853,756. Tubular apparatus for heating or cooling gases. SVENSKA FLAKTFABRIKEN A. B. May 7, 1959 [May 8, 1958], No. 15693/59. Class 64(3) In gas heating or cooling apparatus in which a heating or cooling medium flows through series-connected tubes 1 extending at right angles to the direction of gas flow, one or more partitions 9 divide the gas to be heated or cooled, preferably air, into separate streams flowing in parallel paths and in each path the heat exchange surface area differs from that in the other path or paths. Hence, the streams leave the apparatus each at a different temperatures and each is directed as required e.g. to a different part of a building. In the form shown, the difference in the heat exchange surface area between paths B and C is effected by arranging some of the tubes 1 to extend only across path B. In a further form described, all the tubes extend across both gas paths B and C but fins provided on the tubes are either omitted from some of the tube surface in path B or are of less surface area than are the fins in path C. The general flow of the heat exchanging media is in countercurrent. It is stated that means may also be provided to cause the mean gas speed in the respective gas paths, e.g. B and C, to be different.
