Title: Improvements relating to electrically heated appliances having voltage indicator devices
Inventor: BENSTED-SMITH WILLIAM THOMSON
IPC: H05B1/02
Filed: 1963-01-17
Abstract: 1,077,021. Systems depending on two supply sources. MORPHY-RICHARDS Ltd. Jan. 13, 1964 [Jan. 17, 1963], No. 2136/63. Heading H2H. [Also in Divisions D1 and G1] The circuit connections of an electrical appliance can be switched to adapt it for operation on a relatively high or a relatively low voltage, and a voltage indicator is provided which indicates whether or not the switch setting is correct for the applied voltage. In Fig. 1 a domestic iron 9 has heating elements 7, 8 which may be connected either in series or in parallel by a switch K to the supply 1, 2. A neon or other discharge lamp 6 is connected with resistors across the supply so that it lights only on a high voltage supply. Alternatively the neon lamp may be connected across one heating element only (Fig. 2 not shown). The switch K is set to high voltage and the iron connected up. If the supply is high voltage the lamp lights; if the lamp does not light the voltage is low and the switch must be altered, when the lamp will light. Two lamps may be used, both connected through resistors across one of the heating elements and so arranged that if the switch setting is correct, so that the correct voltage appears across each element, one lamp lights and the other does not. With this arrangement both lamps light if the appliance is switched to low voltage but connected to a high voltage source, and neither lamp lights if the appliance is switched to high voltage but connected to low voltage. The lamp which is on may serve as a pilot light in a thermostatically controlled iron. In another arrangement (Fig. 4, not shown), one heating element X is always in circuit and has two lamps across it and the other element Y is connected in series with the first for high voltage operation, and again one lamp lights when the setting is correct. One element may be always across the supply and a second element connected in parallel with it for low voltage operation only. A travel iron (Figs. 5a, 5b and 5c, not shown) has the switch (K) mounted within the handle (22) at its rear, and the handle pivots about a horizontal axis (31). The member (24) fixed on the base is arranged so that when the handle is lowered for transport the switch lever (23) is moved to the high voltage position. The lamps are behind a translucent cover (30).

Abstract: 365,787. Automatic guns. WHITE, A. E., 5, Quality Court, Chancery Lane, London.-(Colt's Patent Fire Arms Manufacturing Co.; Hartford, Connecticut, U.S.A.) Jan. 22, 1931, No. 2165. [Class 92 (ii).] Relates to cartridge extracting, feeding, and ejecting mechanism for automatic guns, particularly those of the Colt type described in Specifications 133,329, 133,351, and 133,352, [all in Class 92 (ii), Ordnance &c.]. According to the present invention, the pivoted extractor 16 is adapted for guns having a reversible cartridge-feed mechanism by pivoting the extractor to the breech-bolt 6 in the same position whatever be the direction of cartridge feed. Further, the element 23, which serves to retain the live cartridge and to eject the empty case, is mounted on the extractor, preferably by a removable pin 25 and a transferable spring 26 as shown in Figs. 10 and 11, so as to position its effective portion to suit the direction of cartridge-feed. During the rearward movement of the breech-bolt a projection 18a on the extractor removes the cartridge from the belt and the extractor is lowered by engagement with a spring 19 and incline 19a on the cover 3 to position the cartridge in a guide groove 6a on the front of the breech-bolt. During forward movement of the breech-bolt, a spring-controlled pin 20 on the extractor engages a fixed incline 21b to align the cartridge with the chamber the element 23 meanwhile ejecting the case. The extractor is then returned by the engagement of the pin 20 with a fixed incline 22a.

Title: Improvements in or relating to electrical signalling systems
IPC: H04Q1/38
Filed: 1945-01-30
Abstract: 598,552. Automatic exchange systems. HADFIELD, B. M. Jan. 30, 1945, No. 2311. [Class 40 (iv)] A system for bothway direct current signalling over a two conductor line or junction is so arranged that the transmission of either a loop signal or an earth signal has no effect on the receiving equipment provided for earth signals or loop signals respectively. Upon seizure of the junction, line relay A, Fig. 11, connects up guard relay B and relay AA and the current in the loop is reversed to operate polarized relay AP at the distant end which connects up 1AA to complete the forward loop. Relay AP responds only to loop signals. Dialled impulses are repeated by AA as reversals. Relay D releases when battery is reversed upon reply and by connecting up 1DR replaces the earth connection to the loop at 1dr7 by battery to reverse the earth current and to operate polarized relay DP which through DR repeats the signal as a reversal and completes the talking circuit at the outgoing end. Relay I responds to busy flash or manual hold and disconnects the earth connection to release 1S which repeats the signal. In the case of manual hold, is1 is connected between ground and relays BB and DR so that operation of IS holds both. Alternative circuits for the transmission of loop signals by operation nf a contact or contacts a without affecting the earth current are shown in Figs. 2, 4, 6 and 7. By using a suitable battery or no battery at the receiving end of Fig. 2, signals can be made either by reversal or by cessation of current. In Figs. 4, 6 and 7, signals are sent as reversals as the contacts a are changed over. Single current loop signals can be sent by operation of contacts b1 or b2, but b2 also disturbs the earth current. The circuits shown in Figs. 6 and 7 are intended to avoid a change in earth current during the transit period of the contact a. Thermionic valves may replace relays for detecting loop or earth current signals, the valves being controlled by the voltage drops across resistances in the lines and relays being included in the anode circuits to give the necessary indications.

Filed: 1952-01-31
Abstract: 714,446. Looms. FOISY, R., VEZINA, J. A., and FORESTIER, L. Jan. 31, 1952. No. 2655/52. Class 142(2) A loom for pick-and-pick weaving has a drop box on either side, exhaustion of weft being detected at one side and the bobbin being changed at the other. During normal working the drop box B at the magazine side of the loom rises or falls during the forward stroke of the slay so as to be in position for the next pick, the movement being half completed at front centre. On a call for replenishment of weft the box B is raised rapidly by auxiliary means so that it is fully raised before front centre. When a detector indicates substantial exhaustion of weft in a shuttle about to be picked, a shaft 60 is rotated, thus bringing a latch 54 into the path of a prong 56 on a slay sword 2. As the slay moves forward latch 54 is displaced and acts through a system of levers on a roller cam 44, which actuates an arm 40 engaging one of a pair of cams 35 bearing on thrust wheels 34 mounted on guide rods 31 which are thereby lifted to raise the shuttle boxes, the movement being completed before front centre is reached. Roller cam 44 bears against a stop 47 to lock the drop box in this position. The rotation of shaft 60 brings a latch 63 into alignment with a prong 64 on the slay. On the forward movement of the slay latch 63 trips a known bobbin - transferring mechanism through links 65. The drop box B is given its normal reciprocating movement by means of a lever system having a collar 13 bearing on nuts 14 engaging a lifter rod 11.
