Title: Lipstick casing
IPC: A45D40/06
Filed: 1958-02-10
Abstract: 852,033. Lipstick holders. WAHLE, A. Feb. 10, 1958 [May 7, 1957], No. 4248/58. Class 18. A lipstick casing comprises two sleeves 25, 30 which are coupled to a refill 10 so that relative rotation of the sleeves 25, 30 causes the lipstick 20 to be projected or retracted and relative longitudinal movement of the sleeves 25, 30 causes the refill 10 to be moved outwardly from the casing so that it may be replaced. The sleeves 25, 30 are telescopically arranged as shown in Fig. 1. A coil spring 35 urges a collar 28 formed on the sleeve 25 away from a collar 32 formed on the sleeve 30. The lipstick is projected by a pin 21 which rides in a slot 22 and slides in a helical groove 37 on the sleeve 25 so that the liptstick cup is propelled outwards. To remove the refill 10 the sleeve 25 is slid towards the base so that the collar 28 and the sleeve 25 are pressed against the action of the spring 35 to project the refill by the action of the lower edge 25a of the sleeve 25 against an edge 12a of the refill which may then be withdrawn by gripping parts 12, 13, 14. In an alternative embodiment, not shown, the helical groove is provided in an outer sleeve surrounding the refill. In a modification, Fig. 7, the inner sleeve 40 has a shoulder 70 seating a spring 71 which tends to displace the sleeve 40 downwards with respect to the outer sleeve 41 i.e. in the opposite direction to the spring 35 in Fig. 1. The force of the spring 71 is not sufficient to displace the sleeve 40 downwardly since it abuts against a shoulder 43a of the refill which is frictionally engaged by a rim 74 on the sleeve 41.

Title: Improvements in or relating to carrier wave communication systems employing frequency modulations
IPC: H04J3/00
Filed: 1948-02-13
Abstract: 638,336. Automatic frequency control systems. STANDARD TELEPHONES & CABLES, Ltd. Feb. 13, 1948, Nos. 4344 and 4345. Convention dates, March 20, 1947. [Class 38 (iv)] [Also in Group XL (c)] In an electric signalling system in which pulses generated by a source 51 are modulated by a signal source 59 and are then fed to a frequency modulator 53 which varies the frequency of a carrier generator 54, the unmodulated frequency of the generator 54 is stabilized by feeding its output through an amplifier 56 to a discriminator 57 which, provides a regulating voltage for the generator 54. The amplifier 56 is blocked by each pulse, so that the A.F.C. action is intermittent and only occurs during the gaps between pulses. When a multiplex system employs a number of separate carrier generators, each is stabilized in frequency by a similar method.

Abstract: 1,049,795. Fluid digital systems; selective signalling. CORNING GLASS WORKS. Feb. 5, 1964 [Feb. 12, 1963], No. 4908/64. Headings G4B and G4H. A logic network for controlling the relative motion between a machine tool and a workpiece includes three comparators which compare a position signal, e.g. a table position signal, with a desired position signal, the desired position signal plus a constant, and the desired position signal minus a constant, respectively. The comparators may be tri-legged fluid amplifiers as described in Specification 1,031,737. The high and low outputs of the comparators are applied through AND, OR and INVERT logic to drive the table forward or backwards at normal or high speed in accordance with the outputs of the comparators. The comparator which is supplied with the desired position signal unmodified, is a fine position comparator having a range equal to the constant, say 0À001 inch, and is only effective when the difference between the actual and desired position is so small that the other two comparators disagree as to whether the table is too high or not. The AND, OR and INVERT logic elements may be conventional fluid amplifiers having a preferred one of two outputs, i.e. monostable elements. The position signal may be determined from punched tape.

Abstract: 860,393. Automatic exchange systems. GENERAL ELECTRICAL CO. Ltd. Feb. 16, 1959 [Feb. 17, 1958], No. 5051/58. Class 40 (4). [Also in Group XXXVI] In a photo-conductive device intended to give outputs indicative of the location of holes in a punched card, a photo-conductive layer overlays a rectangular array of interdigitated pairs of electrodes on the surface of a transparent resin base through which light is directed from the other side. Fig. 2 shows the back of the device in which one electrode b of each pair is part of a copper strip 11 along the length of a column and the other electrode a is connected by a rivet 9 through the base to a copper strip 3 along the length of a row. In use the device may be mounted in a light-tight box, Fig. 4, and masked by a card 38 (Fig. 3) so that selected pairs only of electrodes are illuminated through holes 39. As part of a translator in an automatic telephone exchange, leads 4-8 could be connected to pulse sources and leads 12-21 to relays, the illuminated pairs of electrodes switching the pulses to the relays to be energized. By using low resistance pulse sources and relays the current through unilluminated and hence relatively high resistance pairs of electrodes is made too small to energize relays connected to unilluminated electrodes.

Abstract: 548,735. Electron beam-valves. FARNSWORTH TELEVISION & RADIO CORPORATION. April 22, 1941, No. 5188. Convention date, Feb. 23, 1940. [Classes 39 (i) and 40 (iii)] A beam from the electron gun 2, 4, 5 is deflected in two directions by plates 8, 9 and 10, 11 and falls alternately on two S-shaped collecting plates 12, 13 forming a cross and having at each end extensions 12E, 13E, Fig. 2, which overlaps when viewed from the gun. The output line 15, 16, tuned to a quarter wave length by slider 19 and connected to load 31, is regeneratively coupled to line 21, 22, terminated by a non- reflecting impedance 24 so that it carries progressive waves, and having two sliders 27 connected rigidly by insulation a quarter wave-length apart so as to deliver to the deflecting plates two voltages differing in phase by 90 degrees ; as a result the beam traverses the oval path A, Fig. 2. During the travel of the beam from X to Y the electrons from X travel to the far end of plate 12 and for these and all intermediate points the electrons of the beam fall simultaneously on the plate 12 which is specially shaped to this end. A similar action on plate 13 occurs during the second half of the cycle, so that two sharplypeaked impulses occur in each cycle, resulting in highly efficient Class C operation. In a modification, one deflecting voltage is applied by a separate source and the beam is intensity modulatedby electrode 4, the output being then a modulated carrier wave. Both deflecting voltages may be derived from independent sources if desired.

Filed: 1925-02-26
Abstract: 230,441. Pollain, L. F. March 6, 1924, [Convention date]. Vaporizing by heat or combustion.-In burning sulphur in a current of air with the introduction of additional preheated air, the combustion products are superheated by passage through a conduit surrounded by the combustion products. or immersed in the burning sulphur. In the Figure, sulphur charged through an orifice 14 burns on the floor la of a furnace, air being admitted by pipe 3 and the products of combustion Leaving by two vertical pipes 7 leading to pipes 8. Two partitions 4, 5 nearly completely separate the top of the furnace from the combustion zone so that additional air entering at 4<a> and passing between the partitions 4, 5, is heated before it mixes with the combustion gases. The mixture, of gases are further heated by the burning sulphur in passing through the pipes 7, 8 whereby the production of sulphur trioxide is facilitated and the deposition of sulphur prevented. The gases leaving the furnace pass through pipes 9 which are cooled by water entering the surrounding casing at 11 and leaving at 12. The gases may receive a preliminary cooling by being circulated in a chamber formed between the floor 1<a> and a second floor beneath it. Both the air used for the combustion and the additional air may be preheated before entering the furnace. The airmay be forced into the apparatus under pressure. or drawn through it by suction.

Abstract: 1,013,419. Grinding. SERVICE (ENGINEERS) Ltd. Feb. 12, 1962 [Feb. 14, 1961; Oct. 17, 1961], Nos. 5365/61 and 37107/61. Heading B3D. A machine for towing articles in the manufacture of ceramic ware, such as plates 14, Fig. 1, comprises a rotatable work support 10, a towing device 16 having a work-engaging portion 26 of flexible foam material with abrasive grains embedded therein, and means for bringing the towing device and the article on the support into engagement with one another. The work support 10 consists of a chuck mounted on a rotatable shaft 17 and having resilient cushions 12 for a plate which is held on the support by a vacuum chuck 13 and arms (not shown), such as described in Specification 652,966. The towing device consists of a narrow wooden base member 22, the lower contour of which is complementary to the plate 14 and on which is stuck a continuous strip or a number of pieces 26 of polyurethane foam embedded with abrasive grains of emery, ground talc or aluminium oxide. The towing device is mounted on a rod 18 which is vertically adjustable to bring the device into engagement with the plate as it is rotated. In another embodiment, the base 40, Fig. 5, is equal in length to just over the radius of the plate and clips 42 releasably secure the foam material 46 in the form of a strip or a number of separate pieces embedded with abrasive, to its under surface. The base is connected by a linkage 34 to a beam 30 and springs 48, 50 act on the beam so that the linkage abuts a pin 37. The beam is carried by a vertically-adjustable rod 60 and a spring 33 acts on the rod to urge a roller 74 into engagement with a cam 72 rotatable by a rod 70 driven by an electric motor, the cam being adjustable to vary its eccentricity and hence the movement of the beam. As the towing device 32 is lowered, the spring 48, which is stronger than the spring 50, urges the righthand end of the device into engagement with the centre of the plate first to assist the foam material in following the contour of the plate, the plate being rotated at the same time as the towing device is reciprocated by the cam 72.
