Title: Improvements in or relating to resistance welding machines
IPC: B23K11/31
Filed: 1944-02-03
Abstract: 574,495. Welding. MALLORY METALLURGICAL PRODUCTS, Ltd., and TUCKER, N. A. Feb. 3, 1944, No. 1966. [Class 83 (iv)] A resistance welding machine of the kind incorporating means for showing the welding pressure is constructed so that a movement between parts in the line of pressure between the foot- or power-operated means and the abutment for such pressure and operative to vary the length of such line, is used to bring about operation of apparatus designed to indicate or record the welding pressure, the construction being such that the said apparatus indicates or records the constant welding pressure at any time during the operation of the machine. In a spot welding machine in which the holder 6 for the electrode 15 is mounted in a pivoted arm 5 operated by a pedal 7 through an adjustable spring 10, the electrode holder is provided with a screwed cap 21 which carries a pressure gauge 12 and which is formed as a cylinder 22 to receive a ,piston 23 which is engaged by a tappet head 24 screwed to the slidable inner member 14 which carries the electrode 15. The member 14 is provided with water cooling connections and is electrically connected to the holder by copper braid in the form of a sleeve or of helical strips. The welding current is initiated by a trip switch striker 11 or by a switch in the holder 6. When the electrode comes into contact with the work further pressure on the pedal moves the holder 6 over the member 14 and the piston 23 is thus raised relatively to the cylinder 22 and the pressure indicated on the pressure gauge. The pressure may be pneumatic, or hydraulic, such as oil, glycerine, or paraffin. The piston may be replaced by a flexible diaphragm or a bellows arrangement may be used. In another form the member 24 may be provided with a head 27 engaging preferably through a washer, a spring 26 and with a tappet 28 for operating the gauge 29. The gauge may be replaced by a recording means such as an indicator 31 moved over a sheet 33 on a drum 32 by fluid pressure through a pipe 30 connected to the end of the cylinder 22. The gauge may alternatively be carried by the fixed electrode 20 or mounted on the arms or on a stationary part of the machine.

Title: Improvements in or relating to loud-speaking telephone equipment
IPC: H04M9/08
Filed: 1947-01-23
Abstract: 628,008. Loudspeaker systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., ROSEBY, P. N., and RICKABY, A. Jan. 23, 1947, No. 2071. [Class 40 (iv)] The hand microphone M in a loud-speaking telephone equipment is arranged to be used as an alternative to the loudspeaker LS for the private reception of a message, the loudspeaker then acting as a transmitter. The microphone and loud-speaker are both of the " sound-powered " type. A call is answered or originated by the operation of key KS which by means not shown connects L.T. and H.T. to the amplifiers, lighting lamp LP. The outgoing amplifier including V1 and V2 and the incoming amplifier including V3 and V4 are connected to line via a hybrid transformer TRC, resistors YC and YD ensuring a substantially constant line impedance as seen from TRC in order to maintain the balance set up by the initial adjustment of resistor YE. The double-tetrode valve V4 operating in pushpull feeds either the loudspeaker LS via transformer TRF and switch hook contacts SH1, or the microphone (when used as a receiver) via the small secondary winding of TRF and contacts SH2; a variable inductance IC constitutes a volume control in the former case and a condenser QL reduces the base response in the latter case. The tendency to sing is minimized by the introduction across the primary of TRF of a thermistor CT having a resistance temperature characteristic such that above a predetermined energy level the loudspeaker response is lessened by a louder incoming signal, by designing TRB and TRE with low impedance primaries to attenuate low-frequency signals, and also by arranging the peak responses of the loudspeaker LS and microphone M at different frequencies.

Abstract: 827,006. Tyre moulding machines. McNEILL MACHINE & ENGINEERING CO. Jan. 22 1957 [June 12, 1956], No. 2268/57. Class 87(2). A press adapted for curing tyres without the use of a curing bag incorporates two mould sections 9, 10, which carry bead seats 8, 21 respectively ; each section being capable of movement towards the other with the uncured tyre therebetween. An upper set of four rollers 46 and lower set of two rollers 45, Fig. 6, are adapted to be moved into and out of a tyre T when enclosed by the sections and are operative to form and press the respective bead edges into the bead seats by a circumferential movement thereon while steam is applied to the tyre interior. After curing the rollers 46 may be displaced axially to crack the tyre from the mould are then further raised to spread the tyre and drain out the water, after which the tyre may be removed. The rollers 46 are rotatably mounted on arms 52 which are connected with limited pivotal movement to ears 54 on the plug 29 of a cylinder 28 which plug is extensible into the mould section axially of the tyre. Lower rollers 45 are similarly connected to a crosshead 49 by arms 47 ; the crosshead being attached to the upper end of a piston rod 30 which extends into the control bore of said cylinder and carries a non-rotating piston 38 on its lower end. Steam is applied to the interior of the tyre via conduit 35, Fig. 4, and its pressure acts on piston 38 which is forced down, arms 47 swing outwardly a limited amount and rollers 45 are then held against the lower bead portion. Simultaneously said cylinder 28 is raised axially into the tyre by the application of fluid pressure to connection 58B of cylinder 58, the piston of which is connected to the cylinder 28 by a linkage 62, 65, 67, and rollers 46 contact the upper bead portion and are maintained in contact under yieldable pressure during rolling. As the two sets of arms move into the tyre both the piston rod 30 and the cylinder 28 are rotated, one in effect being splined to the other. A cylindrical pinion 70 is driven via gear wheels by a motor 84, Fig. 4, and meshes with a ring gear 44 on cylinder 28. After the curing process has continued for some time the pressure on rollers 46 may be relaxed by the application of further pressure beneath the piston 38 and the rollers may be withdrawn. They are then reinserted and the tyre spread, drained and removed. Reference has been directed by the Comptroller to Specification 769,365.
