Filed: 1925-04-08
Abstract: 249,330. Smetzer, E. A. April 8, 1925. Road-traffic signals on vehicles. - In road vehicles provided with a rear stop signal lamp and a tell-tale lamp on the dash, the lamps are arranged on two circuits, one including both lamps in series and the second having only the stop lamp, and a switch preferably connected to the brake-operating gear is arranged so that the first movement operates both lamps and the succeeding movement breaks the circuit including the tell-tale lamp and closes that having the stop lamp alone. In Fig. 1, a clockwise movement of the switch arm V<3> causes the contacts T<3>, T<4> to be bridged by contact V<4>, so closing circuit z<2> and lighting stop lamp E and tell-tale lamp x. Continued movement of the switch arm V<3> opens the circuit z<2> and closes, by means of contacts T<2>, circuit z<6> having lamp E only. Fig. 14 shows the arrangement in which a tail lamp G is added with its appropriate contacts T<1> on the switch. A plug z' closes the circuit z for the tail lamp when the switch engages the contacts T<1>. Movement of the brake lever W breaks the tail-lamp circuit, lights the stop lamp E and tell-tale lamp x, while further movement of the brake lever W causes the lamp E only to be lighted. Figs. 7 and 10 show the parts of the switch. V<2> is a rotary member having switch arms V<1>, V<3> and a spring contact V<4>, V<6> being the lever connected to the brake lever.

Title: Improvements in and relating to electric discharge lamps
IPC: H01R33/08
Filed: 1942-07-07
Abstract: 558,565. Lamp-holders two-part couplings. BRITISH THOMSON-HOUSTON CO., Ltd. July 7, 1942, No. 9393. Convention date, July 11, 1941. [Class 38 (i)] [Also in Group XL] A holder for a tubular discharge lamp having a socket to receive a starter switch device, has the socket contacts and connections so arranged that starter switch devices of different types can be inserted. The socket has four concentric curved slots to receive the pin contacts of the switch device, two of the slots being of keyhole type to receive and lock two headed pins which are provided on each type of switch device. The plain slots receive pins which are present on one type and not on another, and the contacts associated with these slots are normally shortcircuited, the short circuit being opened when pins engage the contacts. The lamp-holder contacts are connected through leads or the screws 32, 41 to terminal plates 30, 39 to which are attached blade contacts 25, 35 associated with two of the curved slots 22, 23 of the socket. Similar contacts 24, 34 associated with the other slots are attached to supply terminals 27, 36. The contacts 35, 34 are normally bridged by a conductive strip 43. When a glow starter switch such as described in Specification 541,925, [Group XXXVII], is used, its two contact pins enter the keyhole slots 22 and engage the contacts 24, 25, leaving the contacts 34, 35 bridged By the strip 43, the connections being as shown in Fig. 11. The bimetallic strip 75 of the switch is deflected when the glow discharge from it to the plate 76 operates and closes the circuit through the filaments 67, 70 and immediately opens it again leaving the filament 67 connected through the contacts 35, 34 to one line 64 of the supply, the other filament being directly connected to the other line 71. With a switch having a bimetallic strip and a heating coil, the switch base has four pins, the two which enter the slots 23 engaging the contacts 34; 35 and moving them away from the bridging strip 43, to establish the circuit shown in Fig. 8. The contacts 59, 60 on the bimetallic strip 56 and the rigid blade 61 of the switch are normally closed, the current passing initially through these contacts, the filaments 67, 70 and the heating coil 50. When the contacts 59, 60 separate the discharge through the lamp is established, but the current still flows in the heating coil 50 preventing, closure of the contacts 59, 60 while the lamp is in operation. Specification 556,536 also is referred to.
Patent GB-1045681-A (GB)
Title: Improved method of operating a brine supply system for electrolysis
IPC: C25B15/08
Filed: 1963-03-11
Abstract: In a mercury cathode electrolytic cell system producing sodium amalgam and chlorine, a portion of the total aqueous sodium chloride brine content of the system is electrolyzed continuously; water vapour is continuously removed from the weakened brine cell effluent to reduce the total volume of aqueous brine periodically to about 1/4 to 3/4 of the original volume; the weakened brine is continuously cycled through a salt-dissolving zone containing solid sodium chloride and calcium sulphate to resaturate the brine which is then passed to the electrolytic cell; and when the total volume of brine has been reduced to between 1/4 and 3/4 of its original volume, adding make-up water to the salt dissolving zone in an amount sufficient to restore the original volume of brine saturated with sodium chloride while leaving the calcium sulphate content of the solid salt undissolved. The total volume of brine may be maintained substantially constant for a time and then the volume reduced by adding no make-up water or the make-up water may be continuously added at a rate less than the evaporation loss, or a combination of these procedures may be employed.

Title: Improvements in or relating to thermoinic valve receiving circuits
IPC: H03G3/26
Filed: 1942-07-09
Abstract: 558,598. Wireless receiving apparatus. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and SCULLY, C. T. July 9, 1942, No. 9543. [Class 40 (v)] A valve in a wireless receiver is blocked except when signals exceeding a predetermined level are received by an indirectly heated thermistor, or thermally sensitive resistance element, the resistance element of which is associated with the cathode of the valve. Fig. 1 shows a thermistor T forming with resistance R3 a potential divider and in the no signal condition applying a positive bias to the cathode of the diode detector D. Received signals are amplified by an amplifier V and part of the output used to heat the thermistor to unblock the diode D. Fig. 2 shows a modification in which muting of the signal diode is effected by a thermistor T controlled by the anode current of the amplifier V. The amplifier V amplifies both the signal from the signal diode and also the voltage from the A.V.C. diode fed through condenser C9 which amplified voltage controls the thermistor T. In the arrangements described negative temperature co-efficient thermistors are used. Positive temperature co-efficient thermistors may be used by interchanging the thermistor with the resistance with which it forms a potentiometer.

Abstract: 929,848. Washing-machines. JAMES ARMSTRONG & CO. Ltd. April 17, 1962 [March 16, 1961], No. 9626/61. Class 138 (2). A horizontal-axis rotary drum washing- machine has an access door 2, 3 in a fluid-tight casing 1 opposite each end of the perforated rotary drum, two vents 10, 11 connecting the drum to atmosphere and independently closable by valve means 14, 15, respectively, and two liquid drains 12, 13 for the drum, also independently closable by valve means 16, 17, respectively. The machine is described for cleaning and sterilizing infected linen, and is shown positioned through a wall 7, the door 3, vent 11 and drain 13 opening into a sterile chamber on one side of the wall 7, and the other door, vent and drain opening on the other side. The materials are loaded through door 2, given a preliminary wash after which the temperature is raised to sterilize the materials, then rinsed and removed through door 3. Before the sterilizing period drain 12 and vent 10 are used and after it drain 13 and vent 11, thereby avoiding re-contamination of the materials or the sterile chamber. The valves 14... 17 may be controlled manually or automatically. In the latter case, once the sterilizing period has been manually initiated, the vent 11 and drain 13 are closed, the vent 10 is opened, and the drain 12 can be opened by pressing a switch manually. When the temperature has increased sufficiently, a thermostat breaks a circuit to close vent 10 and drain 12, open vent 11 and allow drain 13 to be opened by pressing a switch manually. A safety switch closes all valves and stops the motor of the machine if either door 2, 3 is opened. A rinse outlet may be provided on each side of the wall 7, connected to the side of the casing 1 so that the drum is only partially emptied when an outlet is opened; each outlet being closable by a valve controlled in the same way as the drain valves.
