Title: Improvements relating to switch blades and electric switches incorporating such blades
IPC: H01R9/16
Filed: 1963-12-23
Abstract: 1,008,352. Time switches; contact members for switches. CONTROLS CO. OF AMERICA. Dec. 23, 1963 [Jan. 14, 1963], No. 50645/63. Heading H2B. The number of contact blades that can be accommodated in a cam-operated switch for use, for example, as a washing machine timer is increased by arranging each blade to flex in the plane containing its edges. A plurality of blades such as 3 are given a serpentine shape by means of slots cut therein as shown, and are mounted by means of terminal lugs 5 and a hook portion 7 held in position by a sliding bar 8 to facilitate installation and removal. Each blade has a projection 4 co-operating with a groove C<SP>1</SP> in the edge of an associated cam C and its free end, which is bent perpendicular to the plane of the blade, carries contacts 10 co-operating with fixed contacts 11 and 14. In a modification (Fig. 3, not shown) the free end of the blade is divided by the slots so as to form two separate arms, each of which is bent to carry a contact co-operating respectively with one of the two fixed contacts.

Title: Process for manufacturing chlorinated hydrocarbons by oxychlorination
IPC: C07C17/15
Filed: 1970-10-26
Abstract: 1,271,776. Halogenated hydrocarbons. SOC. ITALIANA RESINE S.p.A. 26 Oct., 1970 [14 Nov., 1969], No. 50842/70. Heading C2C. Halogenated hydrocarbons, e.g. dichloroethane, are manufactured continuously by supplying (i) C 1-4  aliphatic hydrocarbons, or their partially chlorinated derivatives, (ii) O 2  or gases containing O 2 , and (iii) HCl gas to a fluid bed of catalytic particles consisting of copper (metal or salts decomposable thereto) and alkali metal salts (e.g. chlorides) supported on an inert granular support material (e.g. SiO 2 , Al 2 O 3 , or decolorizing earths), and the height of the catalytic bed being maintained constant by the addition of solid support material, copper in the form of metal or decomposable salts and alkali metals in the form of chlorides. The oxychlorination temperatures are typically 230- 500‹ C. at pressures 1-6 atmospheres absolute.

Title: Improvements relating to stations for gas-cushion vehicles

IPC: B60V1/00
Filed: 1966-11-14
Abstract: 1,203,417. Air cushion vehicle ground installation. HOVERCRAFT DEVELOPMENT Ltd. 1 Nov., 1967 [14 Nov., 1966], No. 50983/66. Heading B7K. A ground installation for air cushion vehicles is constructed to arrest a vehicle by dispersal of the cushion. An amphibious vehicle 2 in passing from water 9 to a ramp 8 may, through a mechanical fault, be unable to shut off power before reaching a terminal building 4. To provide an emergency stop the ramp is formed with a cavity 5 covered by a perforated platform 10 so that as the vehicle passes over the cavity the cushion disperses and the vehicle sinks. Provision is made for filling (and subsequently emptying) the cavity with water to enable the vehicle to lift-off when the fault has been rectified. The platform may be formed of two slidable overlapping perforated plates to enable the perforations to be blanked off except in emergency, or the cavity may be filled with large stones or open-wall hollow blocks. There may be a succession of cavities up the ramp. In Fig. 7 the cavity 3 is closed by a plurality of pairs of closable doors 15 hinged at 16 and held in the closing position shown by latches 17 remotely actuated through lines 18 from a control unit 19 in turn responsive to pressure switches 21. As a vehicle passes over the switches the control unit 19 releases the latches 17 thereby allowing doors 15 to swing downwardly about hinges 16.

Title: Method and circuit arrangement for controlling flashovers in electrical filters for gas purification
IPC: B03C3/68
Filed: 1968-10-31
Abstract: 1,216,260. Control systems for electrostatic precipitators. BROWN, BOVERI & CO. Ltd. 31 Oct., 1968 [2 Nov., 1967], No. 51687/68. Heading H2H. A D.C. supply circuit for an electrostatic precipitator F includes a differentiating transformer T, the primary of which is connected in series with the precipitator. When a flashover occurs, the current in the primary increases rapidly producing a voltage pulse in the secondary, and this pulse is applied to a control device Re which reduces the supply voltage. In the absence of a flash-over, the output voltage of the transformer T is substantially zero.

Title: Arrangements for the connection of electronic computers to an automatic teleprinter network
IPC: H04L12/00
Filed: 1965-12-07
Abstract: 1,127,788. Telegraphy. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 7 Dec., 1965 [7 Dec., 1964], No. 51820/65. Heading H4P. A computer communicates with a subscriber by way of an automatic telegraph switching network. A circuit associated with the computer translates signals from the computer into switching and telegraph signals, and vice versa. When the computer R wishes to communicate with a subscriber connected to a network connected to lines a, b, a signal is passed via ZS1 to unit SW which actuates relay A, shorting resistor R and increasing the loop current. Timing circuit ZG is operated for a time t. If no dialling signal from the exchange is detected within t, SW returns the computer to quiescent via ZS2. If the dialling signal (no loop current) is received SW requests a dialling digit from the computer R. The dialling digits pass to dial pulse generator NG to operate line contacts SS. A ringing signal (loop current reversal) is then awaited for a time T. If there is no reversal the computer causes the line to be opened, the loop current reversed, and the system returned to quiescent. If reversal occurs ZG operates for t. If a busy signal is received the computer returns to quiescent; if no busy signal the loop current is reduced to normal by de-energizing relay A and the computer is set to transmit data, preceded by a WRU signal. A terminating signal received from the subscriber would set the computer to quiescent at this stage; in its absence transmission takes place, the computer signals being converted to teleprinter characters to operate relay S. The computer terminates the connection by opening SS for a time t. If a subscriber wishes to call the computer, the loop current is reversed and SW sets the computer to receive data.

[Also in Division G4] In a modification of the alarm system described in Specification 1,228,449 which gives an alarm when a car door is opened while the steering column is not locked, an additional switch 11 is provided to prevent the alarm being sounded, when the door is opened, merely because the bolt 32 has not engaged the steering column due to this not being in its central position. This switch is normally held in its closed position by a slider 33, Figs. 4a and 5a, but when the ignition/steering-lock key is withdrawn, spring 35 forces it down to allow this switch to open, Fig. 4b, thus opening the alarm circuit and rendering it inoperative even though the bolt has not yet engaged the slot 29a in the steering column.

[Also in Division F2] A ratchet hoist comprises brake means including a one-way clutch 39 arranged between a fixed brake ring 17 and a rotatable brake ring 11 so mounted as to be axially frictionally engaged, when the brake is operative, between friction rings 10a, associated with a pressure ring 9 keyed to a shaft 8 and further rings 10b associated with a drive element 12. The drive element 12 is threaded on to a brake nut 15, which is in turn threaded on to the shaft 8. A non-corrosive slip ring 14 is pressed by a predetermined amount into a tapered cavity between the brake nut 15 and a ratchet wheel 13, by the element 12 which is then fixed relative to the brake nut 15 by a pin 28. The ratchetwheel 13 is operated by a reversible spring pawl 24 mounted in a casing 4 into which an operating lever 6, 5 is inserted. Movement of the lever 5, 6 in the load lifting direction causes nut 15 and ring 12 to screw up on shaft 8 to lock the brake ring 11 thereto whereupon the load is lifted via toothed wheel 7 coupled to a load hook chain pulley 3. Any tendency for the load to reverse the direction of the shaft 8 is prevented by the one-way clutch member 39. For lowering the load, the ratchet wheel 13 is reversed which unscrews the brake nut 15 and the friction coupling to the one-way clutch 39 is broken until the shaft 8 has now rotated sufficient for the re-application thereof. A catch 16 on the free end of the shaft 8 has an arcuate recess 48 in which a pin 31 secured in the brake nut engages to set the limits of relative rotation between the nut and shaft, and a recess 50 in which a spring ball 29 registers to locate the brake nut in the brake disengaged position in the no load condition.
