Patent GB-521517-A (GB)
Abstract: 521,517. Musical toys. PAVELY, D. A., and WILLIAMS, L. E. Nov. 19, 1938, No. 33730. [Class 132 (iii)] [Also in Groups XXXVIII and VIII] In a toy or other musical instrument hammers, which are permitted to strike the sonorous parts when the hammers or associated parts pass through perforations in a moving tune band, are returned to their normal position by the cam action of the rear ends of the perforations. As shown in Fig. 1, a perforated tune strip 5 passes from a spool 5a to a spool 6 over a table 7 with a transverse opening 8. The hammers 3 are pivoted on an axle 9 and fall under gravity to strike sonorous metallic strips 1 when permitted by the perforations in the strip 5. The hammer is lifted out of the perforation by the edge 12 of the perforation which engages a cam surface 11 on the hammer. The hammers can be lifted together by an eccentric bar 18 to permit changing of the strip 5. Fig. 2, shows an arrangement in which the hammers 3 are formed as levers, the ends of which opposite to the hammer heads 4 pass upwards through perforations in the strip 5. The strip 5 moves between a table 7 and the cover of the casing. The hammer heads are held up by springs 19 when the tune band is absent. Fig. 4, shows an arrangement in which the instrument can be played by means of keys 28, which have depending elements 32 for marking or punching a tune strip passing from the spool 6 to an additional spool 31. The instrument may be made mainly from metal stampings or cardboard parts. It can be used in combination with a kinematograph toy as described in Specification 520,630, [Group XVIII], the pictures to be displayed and the soundcontrolling perforations being, if desired, on the same strip. Moving figures or objects may be associated with the instrument, Fig. 5 shows an arrangement in which the ends of the hammer levers 3 engage levers 35 connected by rods 34 to parts 33 such as the arms or legs of such figures.

Abstract: 1,200,733. Window grilles for vehicles. G. COURTNEY. 16 Nov., 1967 [19 Aug., 1966; 25 Nov., 1966], Nos. 37237/66 and 52993/66. Heading B7J. A vehicle window grille member 1 comprises a grille in the form of a mesh and means for securing it adjacent the frame 6, 9 of an opening window of a vehicle door or tailgate so that the window may be left open to allow the ingress of air with small risk of pilfering from the unattended vehicle, said securing means being releasable only from within the vehicle. As shown, the mesh 4 comprises woven metal wire and is enclosed by a frame 3 secured by clips 5 hooked over the window frame 6 and by clips 7 connected via springs 10 to brackets 11 on the door. One or two pairs of telescoping lockable struts 13, 14 (or strips) are adjusted by screws 15 so as to engage within the window frame channel or to rest on the inside edge of the window frame (as shown) to prevent removal of the grille 1. The base member of the grille frame 3 covers the door handle on the inside of the vehicle, and is padded. The ends of the struts 13, 14 may be bifurcated. The grille frame 3 may comprise L-shaped corner members relative to which the sides can slide and be fastened, and sections of the elements of the mesh are relatively slidable, so that the grille is adjustable in size. In another embodiment, a number of mesh rods are engaged at their ends by lazy-tong link members, and the grille may fit an inclined edge of a window opening. The upper and lower links may have lugs for engagement in the window channels, and the uppermost and lowermost rods be replaced by strips engaging the window channels. The rods may be telescopic.

Abstract: 1,202,399. Pneumatic remote control assembly. IDEAL TOY CORP. 22 Nov., 1967 [17 Feb., 1967], No. 53130/67. Heading A6S. [Also in Division F1] A pneumatically operated remote control assembly (Figs. 1, 3 and 4) includes (a) a control station 12 having a housing carrying an air bellows 66 contractable by a plunger 72 mounted on the housing, a portion of the plunger being exposed for contact by the hand of an operator, (b) a control switch 14 having a housing, a lever 116 mounted for movement between a first and a second position, and an air bulb 118 engaging the lever extension 146 and upon expansion moving the lever 116 to one of its positions, and (c) an air conduit 85 pneumatically connecting the bellows to the bulb, contraction of the bellows thus expanding the bulb and moving the lever to one of its positions. The lever 116 may be connected to control the switch member 36 of track switching mechanism 22 (fig. 1) contraction of the bellows 66 by plunger 72 causing expansion of the bulb 118, moving the lever about pivot 120 against the biasing coil spring 138, member 36 thus moving to rotate triangular member 24 anticlockwise about pivot 34 to the dotted line position in fig. I whereby a vehicle travelling in the direction A in the slotted guide 20 continue in the straight ahead direction B instead of in the direction C defined by member 24 before its actuation by switch member 36. An air vent 80 provided in the plunger 72, which vent is closed by the operators hand when the plunger is pressed, allows the system assembly to return to its initial state when the operators hand is removed, and the resiliency of the bellows' walls causes it to expand to its initial inoperative position. The capacity of the bellows is substantially larger than that of bulb 118 to allow complete expansion of the latter even when small leaks occur in the air system. Several control stations (12, 12' see fig. 1), the respective control switches of which actuate separate track switching mechanisms, may be combined to form a battery of stations by dipping the lugs 166 contained on the base extensions 160 of one control station into the co-operating apertures 162 contained in the respective opposite ends of the same base extensions of a neighbouring control station; each control switch being detachably connected via its base extensions 154 to the base 18 of the track switching unit.

Title: Method and apparatus for curing elongated articles
Inventor: FOLKES HUGH LORAIN
IPC: B29C35/00
Filed: 1967-11-25
Abstract: 1,213,006. Curing elongated articles. DUNLOP CO. Ltd. 15 Nov., 1968 [25 Nov., 1967], No. 53716/67. Addition to 1,175,521. Heading B5A. In a process for curing an elongated article in which successive portions of the article are engaged by heated press units and passed intermittently through a press (Specification 1,175,521) each portion is pressed in two stages, pressure being applied to the leading end of each portion during the first stage, and progressively from the front to the rear of the remainder of the portion during the second stage. In the embodiment illustrated in the figures, which embodiment relates to that shown in Fig. 13 of the abovementioned Specification, two parallel belts moving in opposite directions are engaged by constantly circulating press units 3 and are each passed through a pressing station comprising upper heads 27 and 28 and a common base member 26. The head 27 comprises an upper thrust member 29 having a front portion 43 of constant thickness and a tapered rear protion 42 from which are pivotally suspended first and second pressing plates 31, 30, the front edge of plate 31 being pivoted to the rear of head 28. In operation, the heads are lowered to the position shown in Fig. 7 in which head 28, plate 31 and plate 30 just engage successive press units A, B and C. Further lowering of the heads causes head 28 to act upon unit A and thrust member 29 to act upon the rear edge of plate 31 to cause it to pivot and apply the desired pressure to the rear portion of unit B and to act upon plate 30 to cause it to apply the desired pressure to the front portion of unit C (see Fig. 8). As the units are indexed through the station it can be seen that the portion of the belt between each unit is first compressed at its front portion by flat 30, progressively compressed at its remaining portion by plate 31, and finally evenly compressed over its whole area by head 28. The material between the units is maintained under pressure after leaving the press by clamps 46.

Abstract: 1469590 Variable Venturi carburetters HITACHI Ltd 18 Dec 1974 [19 Dec 1973] 54652/74 Heading F1H A variable Venturi carburetter comprises a vane 6 to vary the flow cross-sectional area of the Venturi portion and mechanically inter-connected with a throttle valve 4 in an air intake passage 2, fuel metering means 15 including a jet or nozzle 11 which co-operates with a needle 10 mounted on the vane, a further passage 24 communicating a chamber 13 of the fuel metering means to atmosphere, the further passage 24 containing means 19, 25 to control the air flow-rate therethrough. When the throttle valve 4 and vane 6 are in their flow restricting positions, the reduced pressure below the throttle valve causes diaphragm 17 to raise needle 19 allowing more air to flow to the chamber 13 so raising the pressure therein which both increases the air flow-rate and reduces the fuel flow-rate past needle 10 so weakening the mixture. When throttle 4 and vane 6 are opened further, the needle 19 descends to constrict air-flow to the chamber 13 lowering the pressure therein so increasing fuel flow past the needle 10 enriching the mixture. In Fig. 2 (not shown) a subsidiary passage (241) is controlled by a solenoid (26) which moves a needle (28) by an amount determined by a controller (29) responsive to the degree of opening of the vane 6 to provide additional control over the air/fuel ratio.

Abstract: 1,185,909. Transistor circuits; radio signalling. PYE Ltd. 21 Nov., 1968 [30 Nov., 1967], No. 54685/67. Headings H3T and H4L. [Also in Division G3] An arrangement for reducing the power taken from the battery supply to a radio receiver in the absence of a signal and including a semiconductor switch device for rendering the D.C. path to the receiver alternately conductive and non-conductive, the device being maintained in the ON position on receipt of a signal, is characterized in that the semi-conductor switch device also acts as a series stabilizing element of a constant voltage supply forming the power supply to the receiver. The arrangement comprises a Schmitt trigger pair TR1, TR2, a multivibrator TR3, TR4 controlling switching transistors TR6, TR7 and an auxiliary control transistor TR5. In the multivibrator transistors TR3, TR4 are coupled by means of resistor R11 and back-coupled via emitter reactors R10, R12 and capacitor C, R10 being made small to obtain a short ON period. Transistor TR3 is given a stabilized bias by means of resistors R8, R9 which are equal to resistors R11, R10 respectively, and diode D1 which is of like material to transistor TR3. The collector load of transistor TR4 comprises diodes D2, D3 the constant voltage drop across which in the ON position biases transistor TR6 conductive. The resulting constant current supplied to Zener diode D5 provides a bias for transistor TR7 which renders it conductive, this transistor and the Zener diode then forming a constant voltage supply to terminal D to which the radio receiver is connected. In the OFF position of the multivibrator transistor TR4 is non- conductive, transistor TR6 biased non-conductive so no current passes to Zener diode D5 and transistor TR7 is biased non-conductive. The arrangement may be held in ON position upon receipt of a signal, which is caused to lower the potential of point E and so render transistor TR3 permanently non-conductive. Alternatively a positive potential may be applied to the point F to render transistor TR5-which derives a positive emitter bias from potentiometer R15, R16-conductive and draw current through diodes D2, D3 independently of the position of the multivibrator. If, in this arrangement a short-circuit should occur between output terminal D and earth, diode D4 becomes conductive, clamping to earth the base potential of transistor TR5, which becomes non-conductive. The circuit then reverts to multivibrator operation whereby excessive continuous current through transistor TR7 is prevented. The positive potential at point F may be derived from the collector of transistor TR1, lowering of the base potential of which causes switching to continuous operation. This hold voltage may be arranged to persist, to cover pauses in a signal by connecting a capacitor between terminal F and earth and including a diode in the connection between terminal F and collector of transistor TR1. Capacitor CD is provided to prevent unwanted RF effects
