[Class 19.] Apparatus for making cylindrical brushes having U-shaped bristle holders 1, Fig. 4, of helical form comprises a bristle conveyer 4 &c. and feeding means for continuously feeding bristles 2 from the conveyer and folding them into a holder 1 during movement for fixing purposes. Bristles 2 are placed on the conveyer belts 4 passing preferably under a pressure roller 5 to a conveyer belt 7 provided with pins 6. Superfluous bristles are caught by a device 8 with a pin conveyer 9 which carries the spare bristles to a table 2a. The main set of bristles passes to two conveyer belts 13 also provided with pins 14. Between the pins 14 rotates a wire feeding disc 15, Fig. 6, on a shaft 16 parallel with a shaft 17 carrying the belts 13. The disc 15 has one or more rings of pins 19. The bristles are folded against a U-shaped trough 20 by the disc 15, the entrance of the bristles to the trough being gradual so that they first travel nearly flat. As the bristles are folded a wire 3 is inserted in the fold from a drum 21 by the disc 15. In order to hold the bristles, two rollers 22 compress the walls of the holder 1 which is further pressed against a counter-roller 24 to ensure that the bristles are inserted right to the bottom of the holder by the disc 15. Cement is applied by a disc 25, Fig. 5, dipping into a trough 27 and carrying glue or putty to the holder 1. A cutting device 28 resembling a milling tool cuts off the ends of the bristles against a counterpiece. After the bristles have been inserted in the helical holder, the several spirals are pressed together to form a circular brush as in Fig. 3. The Specification as open to inspection under Sect. 91 comprises also the case of straight brush parts. Here the disc 15 is replaced by a movable straight edge, operating above and through a slotted table into the U-shaped holder below it. Wire is inserted by the straight edge or the wire may itself form this straight edge. The bristles can also be inserted into helical grooves of triangular cross section in a brush body. Each groove is flanked by subsidiary grooves to guide pressing rollers which squeeze the edges of the principal grooves towards the bristles to hold them. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electrical signalling systems
IPC: H02J13/00
Filed: 1947-06-14
Abstract: 631,836. Electrical signalling systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and WRIGHT, J. G. GORDON-. June 14, 1947, No. 15715. [Class 40 (i)] In a system of remote control by " cadencemodulated " A.F. superimposed on power circuits, check receivers similar to the remotelycontrolled receivers are associated with the transmitter to cause the signal to be repeated and to give visual-aural warning if the first signal fails to operate the check receiver. The system provides for the selection and initiation of signals by an operator and also for the initiation of predetermined signals by a time switch. Normal operation. Momentary actuation of a push-button KTS energizes relay A which locks up. Alternatively time switch TS energizes TA which locks up. In either case relay G is operated, starts timing cams controlling springs ST1 ... ST3, and a 3-phase VF generator VFMA and connects up the cadence controller SRC. In the latter, a number of galvanometer relays GA-GC are energized momentarily over their lower windings, which are cut off after an instant by a sluggish relay WG. On the relapse of the galvanometer relays, one of them, selected by a switch SA1 in the case of operator control and by relay TA in the case of time control, interacts over its upper winding with a relay XG to produce impulses, at a frequency determined by the constants of the selected relay, in the circuit of a relay H after a steadying period timed by springs ST2. These impulses are repeated to a contactor CA which normally shunts the output of generator VFMA. Impulses received by the local check receivers SR energize one of the relays ON, OFF, according to the cadence frequency, and so move relay S to one or other of its two stable positions. If the signal is correct, a circuit will now exist either through a switch SA2, which is ganged to SA1, or through a contact of TA for a relay B which locks up and keeps a " correct " lamp glowing until a pushbutton KGSR is operated. When springs ST3 close, the circuit (apart from relay B) is restored to normal by the operation of relay D. Incorrect operation. If relay B is not operated, contacts ST3 energize relay E which is followed by C which locks over button KCA, operates an alarm bell and energizes relay F whereby E drops out when ST3 opens. Since D is not energized, A. and G remain up and the signal is sent again. At the end of this signal, D is operated to release A and G, whether the local receiver operates correctly or not and no further signals are sent.

Abstract: 838,492. Venting apparatus. DUVAL, B., and WADDINGTON, R. S. May 24, 1956 [June 1, 1955], No. 15782/55. Class 21. [Also in Groups XVIII and XXIX] A device for withdrawing liquid from a container comprises a tubular member 1 e.g. of polythene slidable in a sleeve 22 or other sealing member mounted in an aperture in the container within limits determined by spaced abutments 2, 3, a liquid outlet port 14 in the longitudinal wall of the tubular member, an air reservoir 5 located within the member 1 and provided with air inlet and outlet ports 6, 8<SP>1</SP> respectively, and a manually-operable valve 10 controlling a liquid inlet port to the tubular member. The liquid outlet and air inlet ports 6, 14 are obscured by the rubber or other sleeve 22 when the member 1 is pushed inwardly up to the abutment 3 so that liquid cannot leave the container and air cannot enter it. On withdrawing the tubular member, any liquid within it passes out through the port 14. As shown in Fig. 1, the valve 10 controls a liquid inlet port defined by the valve seat 9 and is operated by a spring-loaded stem 18 of polythene carrying a rubber sealing collar 19 and a push button 21. The valve carries guide segments 11, 12. The air outlet port 8<SP>1</SP> is smaller than the air inlet port 6 and the reservoir 5 is of inverted V-shape. Additional liquid inlet ports 15, 17 which are open to the inside of the container when the tubular member is pressed home are also provided. A fixed volume of liquid is discharged each time the tubular member is moved in and out. To obtain a continuous discharge, the valve 10 is held open by the push button 21 when the tubular member is in its outer position. In a further modification by which a metered quantity or a continuous stream may be dispensed, the tubular member comprises two coaxial metal tubes sealed at their ends to form an annular air reservoir. An air outlet aperture is provided at the inner ends of the tubes adjacent a seat for a manually operable valve such as 10, Fig. 1. The liquid outlet and air inlet ports are arranged coaxially in the side walls of the respective tubes. Specification 718,897 is referred to.

Title: Improvements in or relating to telephone instruments
IPC: H04M1/04
Filed: 1936-06-05
Abstract: 476,492. Supporting telephone transmitters; volume controlling. TELEPHONE MANUFACTURING CO., Ltd., FLINT, J. G., and RYALL, L. E. June 5, 1936, No. 15802. [Class 40 (iv)] In a telephone instrument for use in a loudspeaking telephone system, the microphone is adjustable with respect to the casing which supports the microphone so that the distance between the microphone and user can be varied and means are provided to compensate automatically for the change in magnitude of the speech currents generated. The microphone 1 is normally positioned in a hole 2 of a casing 3, which preferably contains the loud-speaker, and is adjustably mounted on a lazy-tongs device 4. One arm 5 of the device is pivoted at 6, whilst another arm 7, guided by a member 8, carries a slider 9 which moves over a resistance 10 connected in the microphone circuit. In a modified arrangement, Fig. 2 (not shown), the microphone is carried on a stand, the base of which is normally positioned over a spring- pressed plunger to open a pair of contacts in the circuit of a resistance. When the microphone and stand are moved from their normal position, the plunger rises and the closure of the contacts introduces the resistance into the microphone circuit. The resistance may be connected in parallel with the microphone. The compensation may be effected by altering the amplification of a valve in the transmission circuit. When the system is used in a position exposed to a disturbing noise of low-frequency, the microphone such as that described in Specification 449,950, and/or the amplifiers may have a characteristic such that the response to low-frequency signals is less than that for high - frequencies. Specifications 415,767, 416,372,430,158, and 430,567 also are referred to.
