Patent GB-147371-A (GB)
Title: Improvements in automatic or semi-automatic firearms
IPC: F41A5/36
Filed: 1919-09-09
Abstract: 147,371. Fairfax, H. W. Gabbett-. Sept. 9, 1919. Machine guns, gas-operated. Consists in locating the gas orifice D in the cartridge chamber itself, and in providing in connexion therewith means for (1) delaying the action of the breech mechanism, and (2) preventing the fouling of the gas orifice. The gas-piston F is attached to the rod H, which carries a trip collar L, and pistons J, K. The piston K works in a cylinder M which is fixed in the framing C, and the piston J works in a cylinder O which can run on slides P, attached to the framing C, and is attached to the breech-operating mechanism by a rod R. This mechanism may be of the kind described in Specifications 128,354, 138,135, 138,136 and 139,541. On discharging the firearm, the gas pressure blows a small hole in the cartridge case, and a portion of the gas escapes through the passage D, E, and drives the piston F forwards clear of the cylinder G, compressing the air in the cylinders O, M until the rod H becomes locked to the cylinder 0 by means of the trip lever T and collar L. The expansion of the air in the cylinder M causes the rod H to move backwards, thus opening the breech. An inclined edge Z thereupon tilts the lever T and separates the rod H from the cylinder O, allowing the air in the cylinder O to expand and draw the rod R forwards to close the breech. Springs mav be used instead of air to store the energy. The location of the gas orifice D in rear of the bullet prevents fouling of the orifice by the metal of the bullet.

Filed: 1926-09-08
Abstract: 259,195. Colombat, A. S. Sept. 30, 1925, [Convention date]. Drawings to Specification. Bodies.-A light body for a motor-vehicle is constructed by attaching to a wooden framework by glue or other adhesive sheets of aeroplane fabric or like material, or a number of superposed sheets previously jointed together by glueing and pressing. The warp and weft are arranged at a suitable angle to each other and to the longitudinal axis of the vehicle, or either the warp or weft may be parallel to this axis. When more than one laver is used the direction of the warp in different laminµ may be varied. To the sheets are then applied a coating of water. proofing varnish, which also serves to tension the sheets, and finally finishing coatings of paint and varnish or a covering of artificial leather or similar material. The frame members may be rounded at the parts where the fabric is secured in order to avoid cutting of the threads.

Patent GB-361891-A (GB)
Title: Improvements in electro-magnetic interrupters, impulsing devices or the like
IPC: H01H7/03
Filed: 1930-07-23
Abstract: 361,891. Electromagnetic interrupters. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., Caxton House, Tothill Street, RIDDLE, H. J. N. and CANDLER, J. E., Central House, Kingsway, both in London. July 23, 1930, No. 22227. [Class 38 (v).] Retarding devices.-An electromagnetic interrupter or impulsing device of the kind in which the armature is adapted to perform a series of successive movements and to actuate a retarding device for controlling the frequency of said movements is so arranged that the movement of the armature effects movement of a movable member associated with the retarding device to short-circuit the electromagnet and thereby initiate the next movement of the armature. As shown in Fig. 1, the armature 5 when attracted to the cone 1 of the electromagnet 2 the circuit of which is closed at contacts 24, 25, Fig. 2, stores energy in a spring 11 driving upwardly two separately pivoted contactcarrying members 12, 14 the latter of which move slowly under the action of a mercury dashpot 16. At the end of the retarded movement an upper contact 23 on the arm 14 engages a relatively fixed constant 18 short-circuiting the coil 2 through a resistance 29. The consequent release of the armature 5 allows the armature 5 together with the arm 12 to fall without retardation of the arm 14 following slowly under the action of the dashpot 16. At the end of the fall of the member 14 the contacts 24, 25 again come into engagement to complete the circuit of the electromagnet 2 so that a further cycle of operations is initiated. The tuning may be varied by altering the amount of travel of the arms 12, 14 for which purpose the arm 17 carrying the contact 18 is pivotally mounted on the shaft 13 and has an extension pressed by a spring 20 against the periphery of an adjustable cam 19 which may be adjusted by a knob 21. The connection between the armature 5 and the arm 12 consist of a rod 2 pivoted to the latter and surrounded by the spring 11 the lower end passing through an extension of the armature which is prevented from sliding off the latter by a stop 10. The movements of the armature may drive intermittently a rotary switch through ratchet-and-pawl mechanism 7, 8.
Patent GB-465588-A (GB)
Title: An improved method of and means for controlling the load and/or output of power generating plant
IPC: H02P9/00
Filed: 1935-08-08
Abstract: 465,588. Fluid-pressure servomotorcontrol systems. ARMSTRONG, WHITWORTH, & CO. (ENGINEERS), Ltd., SIR W. G., and ORTON, A. Aug. 8, 1935, No. 22438. [Class 135] [Also in Group XXXV] Relates to means for varying the load or output or load and output of power generating plants as set forth in Specifications 380,448, 403,379, [both in Group XXVI], and 405,300 wherein governor-operated control means are adapted to operate the load-varying means, the underlying feature being that the total load on the plant is adjusted to be equal to the output by the reaction of the plant to increase or decrease of said load. According to the invention, the means for controlling the load-varying means is itself controlled by a combination of the movement of a controller for selecting a desired speed of the prime mover and the movement of the governor at its particular setting, the combination of the said movements adjusting the setting of the admission of power-producing substance appropriate to the new speed. As applied to an oil-electric transmission system, Fig. 1, the prime mover PM drives the generator G having a shunt field winding SF, a rheostat R serving to vary the strength of the field. The traction motors and ancillary apparatus forming the load is represented as a series-wound motor M. The manual speed-setting device is shown at C, and acts upon the loading spring 3 of the prime-mover governor PMG. To enable the engine to work at constant output, the generator field is controlled by the rheostat R actuated by an oil motor 1 having a control valve 2. A floating lever 9 is fulcrumed on the valve 2 and has one end connected to the governor sleeve, the other end being connected by a link 8 to a lever 6 fulcrumed at 7 and connected to the controller C. The governor sleeve is connected to the fuel-pump rack 4 by a link 5. With a change in external load, the governor moves the valve 2 thus causing actuation of the vane 10 and rheostat R until ouput and external load are again in balance, the governor simultaneously moving back and bringing the valve 2 to neutral position. The speed of the set can be varied by moving the controller C to change the setting of the loading spring 3 which, at the same time moves the valve 2 to increase or decrease the load. Maximum torque may be obtained before maximum speed is reached and maintained up to maximum speed by providing an adjustable stop to limit the movement of lever 9 towards maximum speed position and connecting the link 8 resiliently to lever 9. In a modification, Fig. 3, the oil motor is replaced by an electrical control comprising contacts C of controlling means comprising a pilot motor arranged in circuit with the generator field so that when the load increases, most of the excitation current is at first passed through the pilot motor which acts as an automatically increasing resistance as it speeds up thus gradually building up the generator field.

Title: Device for coating chips with glue
IPC: B29B7/34
Filed: 1965-05-26
Abstract: 1,099,941. Coating apparatus. BAHRE METALLWERK KOMM. GES. May 26, 1965 [July 28, 1964], No. 22453/65. Heading B2L. In mixing goods in particle form, e.g. wood clips with bonding agents, the particulate mat erial is fed from a bin 5 on to a conveyer bell 7 where it is spread and smoothed into a may by rake 17 and conveyed to a metering roll 19 It is thence conveyed in the form of a thick veil 21 into a chamber 2 where it meets a flow of air from a nozzle 27. The latter changes from circular or near square cross section at its inlet 29 to a slit at its exit 30 of the same area and the air discharged therefrom impinges on a concave reflectors 28 so as to be turned through 180 and caused to flow back on the outside of said nozzle. This flow of air grades the particles, heavier and larger particles dropping quickly to the coating drum 1 below whilst smaller and lighter particles are carried along by the air flow and fall into the coating drum nearer the exit therefrom. Thus the larger particles remain in the coating drum for a longer period than the smaller ones enabling all the particles to 'be coated to the same degree. In the coating drum the particles are sprayed and mixed with bonding agent from nozzles 50. The mixing is done by a number of side by side agitators consisting of bars 40 mounted on shafts 39 rotated by suitable means disposed outside the drum. The bars 40 of adjacent agitators interleave and are so arranged angularly on the shafts as to produce a conveying motion on the particles from right to left in Fig. 1. At the left hand end of the drum 1 are discharge openings 51 covered by slides 71 and flap covers, both of which can be adjusted to produce the desired discharge according to the through flow of the particles. The flow of particles can be adjusted to give the required degree of coating by adjusting the relative angular disposition of the bars 40 on adjacent agitator shafts 39. A baffle 60, adjustable in position is arranged at the end of drum 1 so that air which may be laden with small particles and bonding agent is caused to pass downwards and through the mass of coated particles before being withdrawn from the drum 1 by blower 31, thus causing the air to be filtered before being recirculated. Various forms of nozzles 27 and reflectors 28 are described (Figs. 13-16, not shown), and ease of access to them is provided for cleaning purposes. The shafts 39 and bars 40 are preferably hollow and a heating or cooling fluid (depending on ambient conditions) can be circulated through them. The drum 1 is so constructed that the ratio of the width of the surface of the particles exposed to the spray nozzles 50, to the depth of particles is at least 3:1 at the normal degree of filling of the drum and the ratio of the length of the agitator arms 40 to the diameter of the agitator shaft 39 is less than 5:1.

Title: Method for breaking and separating substrate material
Inventor: RICE WARREN
IPC: H01L21/304
Filed: 1968-05-14
Abstract: 1,211,638. Splitting. TEXAS INSTRUMENTS Inc. 14 May, 1968 [16 May, 1967], No. 22812/68. Heading B5E. [Also in Divisions B2 and H1] A semi-conductor wafer which has been scribed to define a plurality of segments, each of which may contain one or more semi-conductor devices or circuits, is encapsulated between two sheets of thermoplastics material and broken into individual segments which are then separated by stretching at least one of the sheets, thereby facilitating handling of individual segments. Fig. 1 shows an unbroken scribed wafer 6 of Si or Ge encapsulated between sheets 2, 4 of a thermoplastics material such as polyethylene backed by another plastics material having a higher softening point. The sheets 2, 4 are peripherally heat sealed together along a line 5, and the enclosure is evacuated through a needle 8. A second seal is made at 7 during withdrawal of the needle 8. The sheets 2, 4 may alternatively be sealed together in an evacuated chamber. An insert 3 of metal foil or high softening point plastics prevents adhesion of the wafer 6 to the upper sheet 4. The segments of the wafer 6 are broken apart by rolling, first in one direction and then at right angles thereto, while the encapsulated wafer 6 rests on a resilient support. Fig. 3 shows one apparatus for separating the segments 9 of the wafer 6. The sheets 2, 4 are clamped on to a support 14 by a ring 17 and a heated dome 15 is screwed up beneath the lower sheet 2 causing it to expand, thus spacing out the segments 9. Due to the heating the segments adhere to the sheet 2, but the insert 3, Fig. 1, prevents adhesion to the upper sheet 4. The heating also facilitates stretching. Finally the upper sheet 4 and insert 3 are removed and the segments 9 may be individually manipulated using tweezers or a suction probe. Fig. 6 shows alternative separating apparatus, in which stretching of the lower sheet 2 is effected by vacuum forming into a cavity in a mould 20 after initial removal of part 4a of the upper sheet 4 and the insert. The part of the sheet 2 carrying the wafer 6 is stretched across a disc at the base of the mould 20, which disc is provided with a pressure sensitive adhesive so that it retains the sheet 2 after vacuum forming. Thus the sheet 2 may be cut around a groove 28 in the mould 20, and the disc carrying the separated segments of the wafer 6 may be lifted out. Stretching of the sheet 2 may be facilitated during vacuum drawing by heating using radiation from above or heated gas in the mould cavity. In this method it is necessary to adhere the segments of the wafer 6 to the sheet 2 using a heated press prior to separation in the apparatus shown.
