Abstract: 711,734. Valve gating circuits. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 4, 1952 [April 4, 1951], No. 7835/51. Class 40 (6) In an electronic gating circuit the gating pulse is applied through each of two channels comprising a valve and a pulse lengthening circuit to the two sides of a differential output circuit and the signal to be gated is applied to only one channel so that the gated signal free from a gating pulse component is produced at the output. The Figure shows a gating circuit in which the gating pulse G is applied via the two channels V1, V2 and V3, V4, V5 respectively which have similar characteristics to a balanced differential output circuit B and the signal to be gated W is applied only to the channel V1, V2. The s'gnal W is gated in valve V1 and appears at the output O free from any gating signal component which is balanced out. The gating pulse is lengthened in each channel by the effect of the inter-stage stray capacities. The circuit B may comprise a cathode-coupled pair of valves. Specification 692,615, [Group XXXVI], is referred to.

Filed: 1947-03-25
Abstract: 636,007. Staples. FERNBERG, E. B., and FERNTOL PATENTS, Ltd. March 25, 1947, Nos. 8137 and 11177. [Class 89 (ii)] [Also in Group X] Relates to a combination of a fastener, a beading of channel C or like section and a panel, and consists in providing, in the combination, a fastener having an elongate body engaged behind the flanges of the beading and depending from the body, spaced pliable arms which protrude transversely of the beading from between the flanges, pass through an aperture in the panel and are bent to hold the fastener and beading to the panel. A staple 35, Fig. 6, is produced from a blank of the shape shown in Fig. 2 by bending up the legs 40 at the necks formed by the shoulders 38. These shoulders are inclined to centre the staples in the channel 30 which has a closed end 48 but the flanges 31 are cut away at 49 to permit the introduction of the staples as shown in Fig. 6. The head of the staple is bowed so that it is a friction fit in the channel for retention in the required position to pass through slots or a hole in the trim panel 34, Fig. 7, for clinching at 46. The taper at 42 causes the ends of the legs to tend to bend over at a point below the surface of the panel so securing a tight fixing. In modifications the legs are of uniformly reduced width but are weakened as by the provision of holes or notches at the points at which bending is desired. Various forms of head are illustrated in some of which longitudinal strengthening ribs are embossed. In one form the legs 92, Fig. 22, are formed at the sides of the head.

Abstract: 740,033. Control of several motors. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. March 22, 1954 [March 27, 19531, No. 8283/54. Class 38(3) [Also in Group XXXVIII] The speed of a main motor 1 is indicated by the position of a contact arm 24 movable over a potentiometer 17 to regulate the speed of an auxiliary motor 12 to equality with that of the main motor, the contact arm being driven in accordance with the difference of the motor speeds through a differential mechanism. The differential sun-wheels 7, 11 are driven by the respective motors 1, 12 through electromagnetic clutches 6, 13 and various controls are effected as a function of the speed of the main motor by de-energizing one or the other of these clutches. Thus, rocking a brake lever 9a de-energizes the winding 8 of clutch 6, and locks the sun-wheel 7, whereby the contact arm 24 is driven by the auxiliary motor at a continuously decreasing speed to the position a where it closes limit contacts 26 which may de-energize the main motor armature 3 and operate a brake 5 to stop the motor. The closure of contacts 26 may also act on the generator supplying the main motor or upon various safety or signalling devices to produce precise slowdown and stopping of the load 2, e.g., a mine hoist, driven by the main motor. The motor 1 may be reversible, in which case a reversing device 28 is provided for the auxiliary motor. Similarly, by using the brake 15a to disengage clutch 13 and lock the sun-wheel 11, the contact arm 24 is driven at a speed corresponding to that of the main motor to position e to close limit contacts 27. This closure may control various safety operations and initiate the slow-down of the main motor.

Filed: 1944-05-05
Abstract: 602,447. Delivery apparatus. STEVENS, A. H. (Miller Printing Machinery Co.). May 5, 1944, No. 8559. [Class 100(i)] Sheets are delivered from a printing or like press on to a pile 15 by means of a reciprocating carrier 2' carried by a chain 6 driven by an oscillating sprocket-wheel, and to ensure the complete delivery of each sheet before the subsequent sheet is delivered a flow of air or other fluid is delivered through an aperture 18 in a pipe 16 in a direction which is downward and also pointed towards the machine from which the sheets are delivered. The sheets are thus caused to hug the trailing edge of the carrier as it is retracted, and finally as the carriage reaches the fully retracted position shown by dotted lines in Fig. 4 the rear edge of the sheet is blown clear. It is stated that the air flow causes a suction effect' which assists in laying the sheets on the pile. The carrier 2 comprises tapes 8 which pass over pulleys 11, 7, the pulley 7 being driven from a fixed rack 12 by a freewheel device which drives the tapes 8 only when the carrier is retracting, and at a linear speed the same as that of the carrier but in the opposite direction, thus reducing friction owing to there being no relative movement between the sheets and the tapes 8 as the carrier retracts.

Abstract: 785,542. Moulding fibre resin articles. DEEMING, A. G. March 24, 1955 [March 25, 1954], No. 8680/54. Class 87(2). [Also in. Group XXIX] Lids, bowls, tanks and other articles are made by winding fibre, in the form of roving, upon itself between the walls of a former or mould to form a predetermined shape of body or a portion of a body of the article to be made, and impregnating the fibre with liquid solid-setting epoxy or polyester resin before or after winding on the former. As shown in Fig. 1, roving 1 of wool, cotton, or glass fibre, passes from a cheese 2 through guide tube 3 and under a pivoted guide 4 which can be turned on pivot 5 to lie under a bath of liquid polyester. The impregnated roving passes between two squeegee rollers 6 and on to a former 7. The former shown in Fig. 2 is adapted to mould a dome-shaped lid by winding the impregnated roving in a shaped annular space 8 between two plates 9 mounted on a centre spindle 10. A number of plates 9 are mounted on the spindle so that a number of lids can be simultaneously moulded, each mould receiving a separate roving. The former shown in Fig. 3 is constructed to form a hollow member having a cylindrical wall 11 and a dome-shaped end 12 and comprises two dome-shaped, spacedapart plates 13 and 14 mounted on a centre tube 16, the inner plate 14 having a cylindrical extension 15. The impregnated roving is wound on the former between the plates and along the cylindrical extension. Two of the shapes may be assembled together to form a closed hollow body as shown in Fig. 4 by arranging the shapes on a centre spindle passing through the two tubes, and winding further roving on the cylindrical walls to cover the join. Longitudinal roving may be applied to give increased strength. Rectangular or squaresectioned bodies may be made using rectangular or square plates and rectangular- or squaresectioned extensions 15. Metal plates for strengthening or rivet-holding may be inserted between the formers so as to form part of the article. In addition to the coiled roving, roving may be arranged to run radially across the coils at one or both sides, and, if desired. between adjacent coils. The end portions of the radial rovings may extend into a cylindrical extension. By reciprocating a carrier for the radial rovings back and forth relatively to the mould, the radial rovings lie in zig-zag formation between the coils. The spindle holes may be plugged with metal or synthetic resin or may be used to accommodate pipe fittings. Impregnated glass cloth may be wound on to the completed article or incorporated in the final winding on the former, for strengthening purposes. Catalysed synthetic resin may be sprayed on to the roving as it is being wound in the mould.

[Class 34 (i)] [Also in Group XXI] Shell cartridge cases to be used for practice, and other hollow bodies, are reinforced internally to prevent denting or similar damage, by expanding internal slats or blocks outwardly against the inner wall of the cartridge case or body. The cartridge case 15 may have a central rod 10 screwed into a plug 13 in the base and secured by screws 14 threaded into a plate 11 welded to the rod. A sleeve 16 on the rod 10 carries a plate 17 with collar 18 to position the lower ends of a set of inner slats 23 which engage a set of outer slats 22 bearing against the inner wall of the cartridge case. The upper ends of the slats are positioned by a hard-wood ring 21 with a coned seating 28, axial movement of the ring being restrained by a ring 24 soldered to the cartridge case after assembly. The inner and outer sets of slats are disposed as shown in Fig. 2 so that there are no continuous radial lines where slats meet. Axial movement of the sleeve 16 to expand the slats.against the inner wall of the cartridge case is effected by a nut 19 on the sleeve, engaging a threaded part of the rod 10. Hot glue may be poured into the cartridge case and excess removed before expanding the slats against the wall of the case. A closure 25 is finally fitted. The'slats may be tapered longitudinally where the reinforcement of a cylindrical body is necessary. In a modification a single set of slats, with non-radial meeting faces, is employed. In a further modification a central tubular member serves to locate the slats and to guide a pressure member which is actuated by a screw through the base of the cartridge case to expand the slats against the inner wall.
