Title: Improved device for measuring, or indicating, deviation of a surface from an arbitrary datum
Inventor: MERCHANT THOMAS HARRY
IPC: G01B11/00
Filed: 1955-11-26
Abstract: 822,710. Measuring dimensional irregularity. RUBERY OWEN & CO. Ltd. Jan. 7, 1957 [Nov. 26, 1955], No. 33961/55. Class 40 (1). [Also in Group XIX] A probe device for use in measuring or indicating the deviation of a surface from an arbitrary datum comprises a body 11 in which are mounted two telescoping parts 46, 47, movable relatively to each other and to the body 11, one of the parts 46 being connected to the head 45 of the probe and the other part 47 being acted on by the part 46 and being adapted to be held in any position it is made to assume by the part 46. A device for testing wheels has four such probes 11, 12, 13, 14, arranged to act on different portions of the rim, as shown in Fig. 8. A wheel 15 is placed on an electromagnetic block 16 and located by studs 19. Switches 20, 21 are operated when it is bedded down correctly and connect the electrical apparatus of the device to a current supply. Switch 38 is then depressed manually, and this operates an assembly 27, 28 to move the probes into contact with the wheel motor 38a (see Fig. 3), driving a screw 41 to move the probe assembly forward in the body 11, until a forward travel limit switch 61 (not shown) is operated. A second motor 18 is then operated to turn the block 16, and during the first revolution of the block 16, the probe 45 follows the undulations of the wheel 15. During this period a stop ring 52 fitted to the member 46 abuts the end of sleeve 47 and moves it inwardly against the resistance of a clamp 54. At the end of the first revolution therefore, the position of the sleeve 47 gives an indication of the maximum departure of the wheel rim from an arbitrary datum. During the next revolution, the clamp 54 holds the sleeve 47 in place and the probe 45 again follows the undulations of the wheel rim 15. If however, the probe 45 is displaced by spring 51 beyond a predetermined amount, a micro-switch contact 53a is operated by the other end of sleeve 47 and indicates that the maximum allowable deviation of the wheel rim has been exceeded. A circuit diagram (not shown) is provided. The micro-switch may be replaced by a potentiometer to give a measurement of the deviations of the wheel rim.

Abstract: 361,596. Semi-automatic exchange systems. COVENTRY AUTOMATIC TELEPHONES, Ltd., CARPENTER, O. I., and CHUBB, A. A., of General Electric Co., Stoke, Coventry. Nov. 14, 1930, No. 34312. [Class 40 (iv).] In a keysender in which markings by the keys on one or more of a number of wires are stored and transmitted as alternating current signals, each signal and interdigital pause is given a minimum duration to ensure correct operation of apparatus controlled thereby. The key-set P operates the register sets AW.. AZ, BW.. BZ, &c. in turn under the control of relays KA.. KD which operate in turn on re:.ease of each digit key. When KA operates, A pulls up over wipers fs3, fs6 of distributer switch FS which takes one step, releases A, and then takes a second step. It is assumed at present that leads 10, 11 and transformer RC are removed. During the combined operating and release times of A, ground from 9 is connected over fs5 and operated contacts of the first register set to one or more of wires 5 .. 8. If or when the second register has been set, KB operates B and FS takes two similar steps under the control of B during which markings are not transmitted. A then reoperates and markings corresponding to the setting of the second register are connected to wires 5 .. 8. The remaining digits are similarly transmitted, KA falls back, releases KB, KC, KD, and the register in turn, and FS goes home. Wires 5 .. 8 are connected to a source of A.C or to sources of different frequencies and primary windings of transformers are inserted in the wires at 12 .. 15. The secondaries are connected to ground at one end and four outgoing wires at the other end. If different frequencies are to be superposed on one circuit, leads 10, 11 and transformer RC are provided, lead 9 is removed, and wires 5 .. 8 are connected to the sources, the transformers in these wires being omitted. The voice-frequency markings for any digit are now combined over wiper fs5 and pass to line over transformer RC. In modifications, the switch FS is replaced by a relay distributer or by a switch driven at uniform speed, or storage may be completed before transmission commences.

Abstract: 1457698 Firing and trigger mechanism IZHEV MEKHANICHE ZAVOD 7 Aug 1974 34725/74 Heading F3C A firing and trigger mechanism for a selfloading match pistol comprises a hammer 9, Figs. 1 and 2, which is pivotally-mounted at 10 on frame 1 of the pistol, a plunger 12 which is connected to the hammer 9, a firing-spring 15 carried by the plunger 12, a bell-crank 18 which is pivotally-mounted at 17 on the frame 1, a hammer-catch 21 which is pivotally-mounted at 22 on the frame 1, the bell-crank 18 in a cocked position of the hammer 9 having one arm thereof engaging the hammer and having the other end thereof engaging the hammer-catch 21, a spring 31 having one end thereof engaging the bellcrank 18 and the other end thereof engaging the hammer-catch 21, a trigger 28 which is secured by a screw 29 on a base 25 pivotally-mounted at 27 to the frame 1, and a triggering-rod 24 having one end thereof connected by a pivot 26 to the base 25 and having the other end thereof connected with the hammer-catch 21, Fig. 5, the triggering-rod 24 being urged to the hammercatch 21 by a spring 30. The spring 31, Fig. 2, urges the bell-crank 18 to the hammer 9 and urges the hammer-catch 21 to the bell-crank 18 when the hammer is cocked whereby, upon disengagement of the hammer-catch 21 and the bell-crank 18, the latter loads the spring 31 with an additional effort compensating for the loss of the force of friction between the bell-crank and the hammer-catch at the moment of disengagement of the hammer-catch and the bell-crank. In operation, when the hammer is cocked the bell-crank 18 has one end engaging a notch 19 of the hammer 9 and has the other end engaging a notch 20 of the hammer-catch 21. The firing-spring 15 is compressed by the plunger 12 and biases the hammer away from the bell-crank 18. As the trigger 28 is being pulled, the base 25 pivots about the pin 27 to move the triggering-rod 24 which exerts an action upon a lug 23, Fig. 6, of the hammercatch 21. The latter pivots about the pin 22 and the notch 20 of the hammer-catch 21 moves to the position shown in Fig. 4, the hammer 9, Fig. 1, is actuated by the spring 15, via the plunger 12, is disengaged from the bell-crank 18 and hits a firing-pin 11 carried in a breech 4. The bell-crank 18 is rotated by engagement with a cam surface 16, Fig. 4, of the hammer 9, thus applying effort to the spring 31. This effort is transmitted through the hammer catch 21, the triggering-rod 24 and the base 25 to the trigger 28 so as to compensate for the reduction in resistance of the trigger 28 upon disengagement of the hammer catch 21 from the bellcrank 18.

Title: An improved process for producing a moulded article from interbonded glass fibres
IPC: B29C70/34
Filed: 1954-12-02
Abstract: 765,899. Moulding glass-fibre-resin articles. OWENS-CORNING FIBERGLAS CORPORATION. Dec. 2, 1954 [Dec. 3, 1953], No. 34943/54. Class 87(2). [Also in Group XXXII] In producing a porous moulded article of interbonded glass fibres, the fibres are assembled with heat-curable or fusible resin material in a mould and compressed as a porous mass of generally light density while being heated to cure or fuse the resin and to cause the fibres to assume an interbonded relation. The glass fibres are packed into a mould cavity in different thicknesses to result in different fibre densities on compression, the differences being conveniently achieved by laying in fibrous mats pre-cut to the required shapes. The fibre densities are thus adjusted to the character of the article to be moulded, e.g. a crash pad for an automobile, Fig. 2, to be placed over the instrument panel where itwill cushion the jar on passengers accidently thrown forward, should have a higher fibre density at its trailing edge 17 than at its leading edge 16 which should be soft and resilient. Resinous binder material is sprayed as liquid or powder on the glass fibres 14 in the mould cavity, in a proportion of 20-30 per cent by weight of the fibres. Suitable resins are phenol formaldehyde, polyvinyl acetate and polystyrene. A platen 11, which fits the mould cavity 12, is swung on arms 13 and pressed into the cavity with a force sufficient only to compress the material to the shape of the cavity. The mould is then heated according to the curing temperature of the resin. In addition to controlling the density of the fibres, resiliency may be imparted by applying pressure to the surface of the moulded article to break the resin bonds between the fibres to a suitable depth, a convenient method being to pass a roller 20 over the area to be softened. Other methods are to manipulate the article while still in the open mould, using the mould surface as a working surface, or to apply high frequency vibration. Surface resilience may be enhanced by applying a coating of resilient material, e.g. by spraying on neoprene latex, which also retains individual fibres and gives an improved surface appearance. To prevent excessive absorption of the latex by the fibrous body a powdery material, e.g. talc or starch, is added, a suitable mix being 1 1b. starch with 1 gallon latex. After spraying, the material is heat cured on the surface. Surface appearance may be further improved by subsequently spraying rayon flocking on a film of adhesive. The resilient coating may alternatively be applied while the article is being moulded, in which case the material is a plasticised vinyl polymer. The mould surface is first sprayed with a packing agent, e.g. silicone, and the plastisol sprayed on that, after which the fibres and binder are packed in the mould cavity and the process completed. Surface effects such as simulated leather may be produced by embossments in the mould.
