Abstract: 1,115,503. Bolt fastenings. B. LILLY & SONS Ltd. 20 July, 1966 [13 Aug., 1965], No. 34663/65. Heading E2A. An indicator bolt fastening device comprises a bolt and handle assembly adapted to be secured to the inside face of a door of an apartment, an indicator assembly adapted to be secured to the other side of the door to display an appropriate word such as "engaged" or "vacant" of a sign and coupling means to operatively connect these assemblies together so that operation of the handle to move the bolt will also change the word displayed the bolt and handle assembly comprising a casing 2 provided with fixing holes 3 which slidably carries a bolt 4 operatively connected with a bolt operating shaft 1 which shaft is rotatably secured in the casing, and a flanged cover plate 15 which is fitted to the casing to obscure the screw holes therein and which is provided with a captive but relatively rotatable handle 16 adapted to engage one end portion of the said shaft for rotative coupling therewith. In the construction shown the shaft 1 is mounted in a circular bearing hole in the front of the casing 2 and has a flange which prevents rearward axial movement; inside the casing a washer 13 is received on the shaft and a split pin 12 passes through the shaft to hold the washer in contact with the inside of the front wall of the casing. The split pin also holds a T-shaped member in a diametral slot in the shaft 1, the T-shaped member being part of a coupling means, as described in Specification 1115502, by which the bolt and handle assembly is coupled to the indicator assembly. The T shaped member also provides two arms 6 and 8, the arm 6 engaging in a notch 7 in the bolt to move a bolt and the arm 8 engaging the flanges of the casing to limit the rotation of the shaft 1 and the movement of the bolt. The bolt passes through slots 5 in the opposite side flanges of the casing 2 and through cut-outs in the cover plate 15. The handle 16 is mounted on a stub shaft 17 which rotatably engages in a bearing hole in the cover plate, its end portion being spun over washer 19 located against the rear face of the cover plate to maintain the handle in position. The inner end portion of the stub shaft has an axial recess 18 of square section which is engageable with a square end portion of the shaft 1 when the cover plate is forced into contact with the casing 2.

Title: Reduction of the surface resistances of ceramic bodies
Inventor: HOFMANN H
IPC: H01C17/26
Filed: 1972-07-26
Abstract: 1357072 Coated ceramic body SIEMENS AG 26 July 1972 [19 Oct 1971] 34913/72 Addition to 1344329 Heading B2E The surface electrical resistance of a ceramic body is reduced by providing the body after cleaning with a coating of aqueous solution of a metal compound which also contains lithium fluoride, a binder, and one or more refractory oxides dispersed therein, said oxide or oxides being in powder form and in an activated state produced by lattice disturbance and the amount of the oxide or oxides depending on the desired final resistance of the body, drying the body, and sintering the dried body in a dry, inert protective gas atmosphere. The ceramic may be an oxide ceramic, e.g. aluminium oxide. The coating may be applied by dipping or spraying. The oxide or oxides may be ground, thereby producing lattice disturbance resulting in a more intense solid-state reaction at the ceramic surface during sintering. The solution may be produced by dissolving 32 grams of lithium polymolybdate and 80 milligrams of lithium fluoride in 100 moles of deionised water, mixed with 4-6 moles of 10% aqueous tylose solution, and one or more refactory oxides dispersed in the solution. The refactory oxide may be aluminium oxide, beryllium oxide and magnesium oxide. The oxide may be present as a spinel. A particularly suitable aluminium oxide is one prepared by annealing hydrolysed aluminium ethylate so that through γ-Al 2 O 3  and #-Al 2 O 3 , the corundum form corresponding to α-Al 2 O 3  is produced. The ceramic body may be used for manufacture of resistors.

Title: Improvements in braking systems for vehicles
Inventor: HAMBLING STEWART KEVERN
IPC: B60T8/26
Filed: 1963-09-05
Abstract: 1,004,797. Fluid-pressure brakes. GIRLING Ltd. Aug. 20, 1964 [Sept. 5, 1963], No. 35064/ 63. Heading F2F. A device adapted to be inserted between a master cylinder and slave cylinders of one or more pairs of wheels of a vehicle for intensifying hydraulic pressure in the slave cylinders relative to master cylinder pressure is controlled by an inertia-operated valve which closes a by-pass at a predetermined rate of deceleration, whereby below this rate master cylinder pressure prevails in the slave cylinders and above this rate the pressure in the slave cylinders is intensified. The predetermined rate of deceleration is low, i.e. of the order of 0À1 g. to 0À3 g., so that the device acts to cause a quick take-up of clearance when the brakes are applied, since a relatively large diameter master cylinder piston can be used, resulting in short pedal travel. The device is preferably associated with the front brakes only, but may act on all the brakes of the vehicle, in which case it may be formed integrally with the master cylinder. As shown, the device is a separate unit. In the Fig. 1 embodiment fluid from the master cylinder enters at port 15 and initially can pass via a passage 17 to an outlet port 21, since tilting valve 16 is normally held open by the weight of a ball 26 bearing on a stem 25 of the valve. When deceleration rises above the predetermined value the ball 26 runs forwardly up sloping surface 13 to the position shown so that valve 16 is closed by spring 27, after which the fluid entering the port 15 acts on differential piston 22 which produces an intensified pressure in outlet chamber 18. A spring 23 returns the piston 22 on brake release. Ball 26 may also be acted on by a light spring if the predetermined rate of deceleration as determined by the slope of surface 13 is so low that the ball 26 would run forwardly when the vehicle is descending an incline. Alternatively, the device may be maintained level by mounting it on a pendulum. In the Fig. 2 embodiment, ball 31 itself closes a valve opening formed by a, resilient seating 35, so closing off by-pass 36 43 between inlet port 37 and outlet port 45 and enabling spring-loaded differential piston 40 to to intensify the pressure at the outlet relative to that at the inlet.

Abstract: 959, 785. Photoelastic stress gauges. BUDD CO. Oct. 13, 1960 [Oct. 20, 1959], No. 35143/60. Heading G1W. In a method of photoelastic stress gauging a testpiece of transparent bi-refringent material, having Poissons ratio is known relationship to that of the workpiece, is bonded to the workpiece surface, so as to be strained correspondingly therewith, and polarized light is passed through the testpiece in a direction parallel with the workpiece surface and normal to the unknown stress the magnitude of which is related to the bi-refringence fringe pattern observed when the light leaving the testpiece is passed through an analyser As shown in cross-section in Fig.4 the testpiece forming the stress gauge is in the form of a washer having conical inner and outer edges provided with reflecting coatings 33, 34 between which light passes parallel to the work piece surface to which the washer is bonded. A semi-transparent mirror (not shown) reflects downwards a beam of polarized light 37 and transmits the upwardly returning beam which then passes through an analyzer. An alternative washer-shaped testpiece is shown in Fig. 6. As shown in Fig. 7 the testpiece is in the form of a bar 80. The material of bar 80 is so formed as to have several regions (81-87) of permanent bi-refringence. Bi-refringence fringes will be observed in the unloaded state of the workpiece 89 and on loading the shift of these fringes, measured on a scale 88 carried by the bar, gives the stress distribution. The fringe displacement may be plotted for various positions along the bar. Alternatively, the bar may be formed with a longitudinal permanent birefringent region to give a single fringe in the unstressed state (Fig. 8) which is distorted on loading (Fig. 9) according to the magnitude of stress. Preferably the strain gauges of Figs. 7 to 9 have reflecting surfaces normal to the plane of an associated workpiece and the opposite surface may have a lamina of polarizing material to take the place of an external polariscope. Specification 912,760 is referred to.
