Patent GB-232967-A (GB)
Abstract: 232,967. National Cash Register Co., (Assignees of Shipley, B. M.). April 23, 1924, [Convention date]. Cash registers. - In machines for example that described in Specification 192,083 provided with means for printing consecutive numbers on vouchers &c., the consecutive number printer may be disabled for a single operation of the machine or for a series of operations by manipulation of an inderendent control device. As shown in Fig. 1, the number printer of usual construction is actuated by a link 47 pin-and-slot connected at 48 to an arm 50 fast on a shaft 51 rocked at each operation of the machine. In total-printing operations the rocking of a shaft 68 by the setting of the total lever effects through a notched sector 69 a displacement to the left of a guided pitman 71 supported by a bell-crank lever 72, and connected by a pin and slot at 75 to the link 47. This displacement swings the link to the left and breaks the driving connection at 48. In order to disable the actuation in any single operation, a key 86 is depressed to lower a slide 83 carrying a pin 82 co-operating with an inclined edge 81 of lever 72 so as to rock this lever clockwise and swing the link 47 to the left. The key is maintained depressed by a pawl 90 adapted to engage over a shoulder 94 on the slide and rocked for release towards the end of the operation by an arm 95 fast on a shaft 96. To disable the actuating mechanism for any length of time the key is depressed and turned, thus bringing a pin 100 on the key shank beneath a fixed lug 101. If the key should be depressed in error it may be released by turning it in the opposite sense, a pin 98 on the shank then bearing against a lug 99 on the pawl 90 so as to displace this pawl to free the key. In a modified construction, shown in Fig. 5, the key 111 is depressed, as before, to produce disablement for one operation and is latched and released by the pawl 119 and arm 122 respectively. If, however, the key is depressed and then rocked slightly to the left, a shoulder 128 comes below a flat surface 127 of the guide pin 126 and the key may thus be retained depressed.

Title: Compositions containing coal tar pitch
IPC: C08L95/00
Filed: 1965-06-01
Abstract: Thermoplastic compositions comprise a coal tar pitch and a phenoxy resin having the formula [-OROCH2CH(OH)CH2-]n where n is an integer of at least 80 and R is the divalent residue of a dihydric phenol after removal of the hydroxyl groups.  The compositions may be formed by adding an organic solvent solution of the resin to the molten pitch, stripping-off the solvent, adding any optional ingredients and milling at 125-200 DEG  C.  Optional ingredients specified are fillers, e.g. sand, granite, iron oxide, TiO2, talc, mica, or coal, rubbery diolefin-acrylonitrile copolymers which may be added in solution and liquid isoprene or butadiene polymers.  If the composition is pulverized an anti-blocking agent such as an aqueous elastomer latex which coats the particles with the elastomer may be added.  The compositions are useful in coating applications.

In a railway track cross-level or super-elevation sensing device, a gyrovertical is used as the datum and in the level condition light is either, as shown in Fig. 1, passed from a source 10 to a receiver 14, such as a photo-electric cell, by way of a mirror 12 carried by the gyrovertical, or, alternatively prevented from passing from the light source to the receiver by a shadow element on the gyrovertical. The device may be provided on a shadow board 19 of apparatus as described in Specification 1,014,324 (Division G1) wherein the grade rail is levelled longitudinally using the appropriate edge of shadow board 19, which is carried by a rail-engaging support 16, and crosslevelled by the levelling device on the board. The gyroscope is a vacuum driven gyrovertical with the mirror 12 attached to the gimbal 20, Fig.4, which would, in an aircraft, carry the horizon bar. A cover 21 carries the light source 10 and has a window 22 through which the reflected beam passes to the receiver 14, the cover being angularly adjustable by a worm and pinion to allow for gyroscope 17 settling in a reference datum which is not accurately horizontal.

Abstract: 1307298 Folding fins for missiles BOFORS AB 14 May 1970 [14 May 1969] 23506/70 Headings B7G and B7W [Also in Division F3] A foldable steering fin for a missile has a folded storage position (Fig. 3) and a normal extended position (Fig. 1) into which a foldable part 1 of the fin is biased for motion on three parallel axes 5, 6, 7 so that when it is pivoting, during the final part of its motion (from Fig. 7 to Fig. 1) the part 1 undergoes substantially linear motion towards its normal position. The foldable part pivots about pins 5a, 5b (on axis 5) which engage links 4a, 4b which in turn are rotatably mounted on the part 1 by a shaft on the axis 6. A rod 8 pivotally connected to the part 1 by a shaft 7 is connected to a piston 9 which is urged to move the part 1 to its normal position by a stack of disc springs 15. The part 1 is locked in its normal position by mating longitudinal ridges 16 and grooves 17. In Fig. 7, it is seen that the axis 6 pivots about the axis 5, the link being shown diagrammatically between the axes as being slightly larger than the perpendicular distance between the rod (shown diagrammatically between axes 6 and 7) and the axis 5. When the axis 6 moves to 6<SP>1</SP> (i.e. during the final part of motion of the part 1) its motion, and that of the part 1 is hence substantially linear.

Abstract: 1518416 Reinforced superalloy bodies WESTINGHOUSE CANADA Ltd 8 June 1976 [9 June 1975] 23588/76 Headings C7D and C7F A composite material comprises a matrix of Ni- or Co-based superalloy, and filaments coated with hafnium carbide, hafnium nitride, titanium nitride, zirconium carbide or zirconium nitride as a barrier layer to prevent diffusion at elevated temperatures. The filaments may be of graphite, SiC, Mo, W, or W alloyed with one of K, Si, Re, ThO 2  or hafnium carbide. The barrier layer is deposited by sputtering, electron beam evaporation, ion plating or preferably by chemical vapour deposition. Examples relate to coating wires of W-2% ThO 2  with hafnium carbide, hafnium nitride, and titanium nitride. In the figure a W filament 3 passes through chamber 4 sealed by Hg seals 5, 6, the filament being heated to 900-1300‹C by current supplied to electrodes 15,16. To deposit hafnium carbide, hafnium is held in chamber 10 and converted by HCL gas or CL2 to hafnium chloride which flows out into tube 12 and reacts with a CH 4 /H 2  mixture from tube 13. To deposit titanium nitride, titanium chloride is reacted with N2. In the Examples, coated filaments are placed in a container and surrounded with superalloy powder, the container being subjected to hot isostatic pressing in argon.

In a lathe, having one or more toolslides, a polygonal-shaped turret 6 is slidably mounted on a shaft 21, the axis of which is above the workspindle 7 carrying a chuck 9. The slides, which move transversely to the work-spindle, may be sliding as at 13, Fig. 3, or swivelling as at 14. During the machining-operation, the slides and the turret move along predefined relatively short paths and, on returning to the loading-position, move a relatively longer distance, corresponding to the size of the work, to allow automatic feeding and removal of the work. The shaft 21. is supported by an adjustable-bracket 5 in a pedestal 4, connected to the headstock by a cross-beam 3. The slides and turret are fed through Maltesecross arrangements 11, 12, respectively, both being mounted on the shaft 21. A cam-drum 15, controlling the movements of the turret, is located in the cross-beam 3, and a control-drum 16 operates at each working-cycle. In use, the workpieces are fed by a shoot 18 and ejected along a channel 19. The blank X, which is next in line for machining, and the piece Y, which has just been machined, are held clear of a circle D representing the swing of the tools. In a modification, large work-pieces are fed from a shoot adjacent the pedestal 4.

[Class 135] Two constructions of valves with electromagnetic locking devices preventing their opening (except by a special operation) in the event of failure or cutting-off of the electric current from any cause, are described, for use where the current is required for igniting gas passing through the valve, or where the electric circuit includes a fuse or other control device. In Fig. 1, rotation, to a slight extent from closed position, of a knob 5 carrying a switch detent 15 permits closing of contacts at 14. Should current then flow through the coil of a stationary electromagnet 8 a locking-plunger 9 is withdrawn from a slot 11 in the knob 5, and the knob 5 may be turned further to open the valve fully.
