Title: Improvements in or relating to the production of toothed thermoplastic articles
IPC: B29C48/12
Filed: 1963-06-21
Abstract: 1,041,664. Extruding plastic articles. A. STOEHR. June 21, 1963 [July 5, 1962], No. 24838/63. Heading B5A. A method of producing toothed thermoplastic articles, such as brushes or combs from polyethylene comprises continuously extruding the material through a die 5 to give a suitably ribbed profile, repeatedly cutting the ribs transverse to the extruded direction by a rotating blade 10 and simultaneously straining the extruded form by pulling with wheels 15, 16 in the extruding direction. The cut material is cooled in zone 20 by air or water, and cut into round brushes of desired length by a blade 22. Combs and flat brushes are similarly produced by cutting a flat extruded ribbed profile with a reciprocating blade (Fig. 7, not shown), and hollow brushes with the bristles directed inwards, by extruding an internallyribbed tube cut by a rotating blade within the extrusion die (Fig. 6, not shown).

Title: Improvements in constructional toys
IPC: A63H33/10
Filed: 1949-09-28
Abstract: 696,475. Constructional toys. HOMMADE, Ltd., and HARWOOD, C. D. Sept. 28, 1950. [Sept. 28, 1949] No. 24884/49. Class 132 (iii). [Also in Groups XXIV and XXXII] In a constructional toy, means are provided for securing a wheel or other part to a shaft or rod which passes through it. In Figs. 1, 2 the spring wire forming a helical coil securing device 3 of slightly smaller internal diameter than a rod 1 has one end removably received by a hole 2b in a pulley 2, and the other end formed as an adjusting loop 3a. A spring clip 5 and a washer 4 form a stop for the pulley on which a force tending to rotate the pulley relative to the rod in one direction (counterclockwise in Fig. 2) tightens the coil and the pulley is locked against rotation. An opposite force tends to unwind the coil, so that the pulley may rotate more or less freely. To lock the pulley in either direction a second securing device may be engaged at the other side of the pulley. Fig. 4 shows a U-shaped member 6 secured to a rod 1, the other end of member 6 being pivoted on a second rod 1<SP>1</SP>. Plates with lugs and having perforations adapted for engagement by a rod and securing device may be asembled to form a continuous surface on a framework built up from connected helical wire springs, Fig. 6 (not shown). The pulley 2 may be fitted with a rubber ring to simulate a tyred wheel or may have gear teeth. Specification 660,321 is referred to.

Title: Improvements in or relating to central heating systems
Inventor: WOLFENDEN HENRY CHARLES LEONAR
IPC: F24H9/20
Filed: 1961-07-11
Abstract: 1,025,925. Heating buildings; hot water supply systems. RADIATION Ltd. Oct. 11, 1962 [July 11, 1961], No. 25094/61. Heading F4A. A hot water central heating system in which a boiler 1 supplies a space heating circuit having radiators 2, and a calorifier 3 in a hot water storage tank 4, which latter feeds a draw-off supply 6, is fitted with means for controlling the heat output of the boiler, and a device for operating the means to permit maximum heat output when the space heating circuit requires heat input, and a reduced heat output adequate for the calorifier when the space heating circuit does not require heat input. As shown, a pump 7 passes hot water from the boiler 1, which may be gas or liquid fueled, through the radiators 2 and the calorifier 3. A thermostat 14 senses the temperature of the space being heated, and, when this temperature exceeds a predetermined value, opens a switch which cuts off the electric power to the pump 7 and to a solenoid operated two-position valve 12 in the boiler fuel supply line 11, thus stopping heat input to the radiators, and causing the valve 12 to move from a fully open position to a partly open position to reduce the heat output of the boiler 1. Flow of hot water to the calorifier then continues by convection through a by-pass line 8 having a non-return valve 9. Pump 7 is restarted, and the valve 12 fully opened again, when the temperature in the heated space falls below a predetermined value. A water thermostat 17 in the output pipe of the boiler controls an "on-off" valve 16 in the fuel line 11 to cut off the fuel supply if the water temperature exceeds a predetermined value. A time-switch may also be incorporated to control the valve 16.

Title: Improvements in ceramic objects and a method of manufacturing ceramic objects
Inventor: BENNISON PETER
IPC: C04B37/02
Filed: 1962-06-30
Abstract: A cermet in which the metal content varies gardually from a zero content in the core to a maximum at the surface is produced by hot pressing together layers of the powder mixture containing the required proportions of metal and ceramic.  The ceramic may be silicon nitride and the metal may be tantalum, tungsten, niobium, molybdenum, or rhenium, or their alloys, hot pressing being effected at 1600-1900 DEG C. The high metal content at the surface of the cermet helps in the joining of the cermet to metals by brazing.

Title: Improvements in and relating to multi-channel carrier wave transmission systems
IPC: H04J1/04
Filed: 1945-09-28
Abstract: 637,712. Multiplex systems. SUEUR, R. Sept. 28, 1945, No. 25233. Convention date, Oct. 10, 1944. Drawings to Specification. [Class 40 (iv)] In a multi-channel carrier wave system of the type employing a plurality of groups of channels the frequencies of the channel carrier waves in each group are chosen so that the second harmonic of the lowest carrier wave is higher than the frequency of the highest carrier wave. Both sidebands are transmitted and only one carrier-frequency filter is required for the formation of each group of channels. In a two-stage modulation system the same channel frequencies are employed for each group and a different group-modulation carrier is used for each group of channels, these frequencies being chosen so that only two carrierfrequency filters are required for the production of each group of group-modulated channels. The filters used are all low-pass filters.

Title: Wireless control and synchronisation of clocks

Filed: 1946-08-26
Abstract: 646,129. Electric selective signalling; lampfailure alarms. PANERAI, G. Aug. 26, 1946, Nos. 25438 and 25439. Convention dates, Aug. 30, 1945, and Jan. 14, 1946. [Classes 40 (i) and 118 (ii)] [Also in Groups XVIII and XL (c)] In a wireless clock system (see Group XVIII), each receiving clock is provided with an analysing device which ensures that only true synchronizing impulses effect synchronization of the receiving clocks. The device comprises, Fig. 8, a spur-wheel 85 rotated in step-by-step manner by a pawl 84 upon reception by a controlling electromagnet 82 of a starting impulse. The spurwheel 85 carries a brush 86 which moves over contacts 87, 88 ... 92 connected through electromagnets 93, 94 ... 98 to selecting discs 99, 100 ... 104. The synchronizing impulse is of a definite form and the arrangement is such that just prior to its reception the electromagnet 82 starts to step-on the wheel 85; if the impulse then received is of true form, respective discs 99 ... 104 are moved or not moved by their respective electromagnets 93 ... 98 to assume in all a predetermined relationship in which slots in the discs coincide to allow either one of two levers 105, 106 to fall and so operate the electromagnet which effects synchronization. Adventitious disturbances although received will not cause the discs 99, 100 ... 104 to take up the predetermined relationship and so no operation of the synchronizing electromagnet takes place. Lamp-failure alarm.-A lamp 10, Fig. 3, used in the transmitting station of the clock system in co-operation with a photo-cell, not shown, is fixed on a mounting 75 which is held in its normal position by an electromagnet 76 in series with the supply and to which is also fixed an auxiliary lamp 78. If the lamp 10 burns out, the supply is interrupted and a spring 77 rocks the mounting 75 counterclockwise, bring- ing the lamp 78 into the operative position with respect to the photo-cell. During movement the mounting 75 closes the circuit of an alarm signal 80. When the lamp 10 has been replaced, the mounting 75 is returned to its initial position.
