Title: Improvements in or relating to telephone line-finder switches
IPC: H04Q3/00
Filed: 1954-01-05
Abstract: 746,290. Automatic exchange systems. WESTERN ELECTRIC CO., Inc. Jan. 5, 1954 [Jan. 12, 1953], No. 252/54. Class 40 (4). A bidirectional call-finder employs for testing and switching-through a fast-operating electropolar relay, that is, a relay which has a polarizing winding and an operating winding and which holds over the polarizing winding after the operating circuit is opened. Such a relay is described in Specification 272,872, [Class 40 (iii)]. A call-finder is described having two sets of wipers with two electropolar test relays 11, 12. When a call is made, line relay 2 marks the test terminal with battery through cut-off relay 3 and connects up group start relay 6 which marks the appropriate terminal in vertical bank 14 and grounds start wire 8 to operate stepping relay 9 in the first idle finder. The last relay interacts with vertical magnet 13 until change-over relay 10 energizes over vertical wiper 19 in series with 9, locks and connects up rotary magnet 17 to interact with 9. Relay 10 also provides an operating loop for the selector line relay 54, and guard relay 55 grounds wire 34. The upper polarizing windings of 11, 12 are now energized, while the lower windings are connected to test wipers 33, 23. When a calling line is found, 11 or 12 energizes in series with cut-off relay 3 and holds over its polarizing winding. If both wipers 33, 23 encounter calling lines, preference is given to relay 12 which opens the holding circuit of 11. The operated relay 11 or 12 cuts the drive, switches through and grounds the test wiper to energize 3. It also removes a shunt to allow operation of relay 15, which disconnects the operating windings of 11, 12, releases 9, 10 and extends start wire 8 to succeeding finders. Release by the calling party results in the removal of ground from wire 34, so that 11 or 12 falls back and connects up release magnet 26. Relay 15 goes back when the finder is normal unless start wire 8 is grounded, in which case it holds until the existing call has been dealt with. If the finder fails to find a calling line, relay 15 operates over 11th rotary step springs 25 and effects release. Relay 15 also operates if the calling party hangs up before his line is found, or if the finder is moved offnormal by a maintenance man. Specification 379,749 also is referred to.

Title: Improvements in electrically controlled door operating apparatus
IPC: E05F15/02
Filed: 1927-01-05
Abstract: 264,162. National Pneumatic Co., (Assignees of Forman, P. R.). Jan. 6, 1926, [Convention date]. Operating and controlling doors and barriers pneumatically, electrically, and by treadles and the like. - A vehicle door is opened by a pneumatic motor when the vehicle brakes aie applied and electrically-operated means controlling the door motor are simultaneously operated by the car-operator and by a passenger. The arrangement also provides means whereby the doors may be operated independently of the treadle device by the driver or an attendant from stations accessible from the inside or the outside of the vehicle. In the system shown in Fig. 4, the valve 111 of the pneumatically-operated doormotor 3 is controlled by a magnet valve 110, a push-button control switch 114 is provided for the motorman, a treadle 22 that is depressed by the passengers operates the contacts in a door control switch 97, and 124 is a switch device that is arranged to be operated from the outside of the car. Fig. 1 shows the arrangement from the outside of the door, and Fig. 6 shows the treadle switch mechanism in detail. Current from the main is supplied to the control system at 121 leading to the motorman's control, and at 127 leading to the collector's switch 124. When the. motorman applies the brakes the air line pressure is applied to the cylinder 145 to move its piston against a spring and close contacts 118, 120. The motorman then depresses push-button 135 and closes contacts 115, 116. Current from the mains 121 then flows through the wires 119, 113 to the treadle-operated switch contact 102. The depression of the treadle by a passenger causes the plunger 98 to close contacts 101, 102 through a contact disc 100. Current then passes through the wire 109 to the valve 110, and the valve 111 is moved to admit air to the engine 3 to open the doors 2. The step 9 is lowered through an arrangement of lever mechanism connected with the door motor. The rod 98 remains depressed and contacts 101, 102 remain closed through the action of a plunger 105 and lever 106 until the passenger has cleared the step, when a spring 13 turns the step into its upward position. The spring 131 then moves the rod 98 and treadle 22 and opens the contacts 101, 102, and the magnet valve 110 admits air to the other side of the engine piston to close the doors. By the motorman exhausting the air in the brake air line the piston of the cylinder 145 is permitted to return under the action of its spring to open the contacts 118, 120, and the apparatus is reset for the next operation. The motorman may open the doors directly by depressing the button 136 after the brakes are applied. Current then passes through the wire 119. contacts 117, 142, 123, and wires 122, 109 to the magnet valve 110. The doors may be opened from outside the vehicle by means of a key 156 carrying a contact plate 164 that closes the contacts 165, 166 and connects the valve 110 with the main 127.

Title: Radio range measuring systems
Inventor: MACKINTOSH JAMES EWEN
IPC: G01S1/02
Filed: 1952-01-04
Abstract: 715,347. Radar; radio signalling. MINISTER OF SUPPLY. Dec. 31, 1952 [Jan. 4, 1952], No. 390/52. Classes 40 (5) and 40 (7) A range measuring system comprises at a first station (Fig. 1) a modulation signal source 1 and frequency divider 2 intermittently connected by a switch S1a to a transmitter 3 connected to energize the aerial over ganged switch S1b. At a second, station an aerial 10 is coupled over switch S2a to receiver 11 which feeds the received modulation signal FR to phase discriminator 13. A second input to the discriminator is provided by the output of stable oscillator 15 which is fed through frequency divider 16 and switch S2b. The output of the discriminator is used to control reacter 14 which in turn controls the oscillator 15 to bring it into phase with the received signal. The reactor 14 is arranged to have a long time constant and maintains the output of the oscillator 15 constant after the opening of S1a and S1b at station 1. When this occurs the switches S2 at station 2 are also moved and the output of the divider 16 is fed through preset compensating phase shifter 17 to modulate transmitter 12 now coupled to aerial 10. Signals from the second station are received at station 1 and the modulation frequency output of receiver 4 compared with the output of divider 2 in phase meter 5 to give a distance indication The carrier frequency of transmitters 3 and 12 may conveniently be the same and a normal communication transmitter-receiver used for units 11 and 12 at the second station. The oscillator 15 may be replaced by two oscillators whose outputs are mixed to give the required frequency and the reactor control applied to one of them. This arrangement gives a greater range of phase shift control. Two separate modulation frequencies may be used in the system to provide a fine and coarse indication of range. Manual operation of the switches S2 may be carried out when the received modulation ceases or a relay system may be employed changing these switches over for a predetermined period. To select and determine the range to a given one of a number of stations the latter may be made to respond only when one or more of a number of different signalling tone modulations are radiated by the first station.

Title: Azomethine compounds and compositions comprising the same
IPC: C11B5/00
Filed: 1953-01-07
Abstract: The invention comprises the azomethines obtained by condensing equimolecular proportions of a cyclic hydrocarbon substituted by at least one carbonyl group and at least one hydroxyl group in ortho position to each other and an aliphatic primary monoamine the amino group of which is approximately in the middle of the carbon chain and which contains no hydroxyl group, and a process for the preparation thereof as above.  By approximately in the middle of the carbon chain is meant nearer to the middle of a chain containing at least 3 carbon atoms than to the end thereof, if not at the middle of the chain. The aliphatic monoamine may contain from 9 to 18 carbon atoms in the chain.  Ortho-hydroxy cyclic carbonyl compounds which may be used are o-hydroxy-, 2-hydroxy-3,5-dichloro-, 2-hydroxy-4-methyl-, 2 - hydroxy - 5 - (tert. - butyl) -, 2 - hydroxy - 3,5 - dimethyl -, 2 - hydroxy - 3,5 - diisobutyl - and 2,6 - dihydroxy - benzaldehyde, resorcinol - dialdehyde - 2,4, 2 - hydroxy - naphthaldehyde, 2 - hydroxy - acetophenone, o - hydroxy - propiophenone, 2 - hydroxy - 5 - (tert. - butyl) - acetophenone and 2,21 - dihydroxy - benzophenone.  In the examples azomethines are formed by reacting o-hydroxybenzaldehyde with a primary aliphatic amine having a carbon chain of about 14 carbon atoms, and by reacting 2 - hydroxy - 3,5 - dichlorobenzaldehyde, 2 - hydroxy - naphthaldehyde, 2 - hydroxy - 5 - (tert. - butyl) - benzaldehyde and 2 - hydroxy - acetophenone with a primary aliphatic amine containing about 10 carbon atoms in the chain.  The azomethines may be used as antioxidants.ALSO:Mineral oils and fats are stabilized by the addition of an azomethine obtained by condensing equimolecular proportions of a cyclic hydrocarbon substituted by at least one carbonyl group and at least one hydroxyl group in ortho position to each other and an aliphatic primary monoamine free from hydroxy groups, the amino group of which is at the middle of the carbon chain of said amine or is nearer to the middle of the carbon chain than to the end thereof, the said carbon chain containing at least 3 carbon atoms. A mixture of said azomethines may also be used.  A mineral oil lubricant may also contain an ester of phosphoric or phosphinic acid such as an ester of a lower aliphatic alcohol with a phosphinic acid containing an aromatic hydrocarbon radical.  A suitable quantity of additive is 0.2 to 0.5 per cent by weight based on the weight of oil or fat.  In the examples, an azomethine obtained by reacting o-hydroxy-benzaldehyde and a primary aliphatic amine containing about 14 carbon atoms is added to a paraffin oil with the butyl ester of bis-(p-chlorophenyl)-phosphinic acid, and an azomethine obtained by reacting 2-hydroxy-3,5-dichloro-benzaldehyde and a primary aliphatic amine containing about 10 carbon atoms is added to a mineral oil.

Abstract: 983,790. Targets. P. THEISSEN. Jan. 8, 1964 [Feb. 28, 1963], No. 937/64. Drawings to Specification. Heading F3X. A firing range installation has driving means for moving a target into and out of the target position, and radio transmitter situated remotely from the target and a radio receiver operatively connected with the target driving means. The transmitter normally emits a continuous locking signal and has a control device for interrupting the locking signal when movement of the target is desired and the receiver is responsive to the continuous locking signal to prevent operation of the target driving means by extraneous radio signals. Operation of the control device simultaneously interrupts the emission of the locking frequency and causes emission of a control signal which is picked up by the receiver to cause the driving means to raise the target to the target position or drop the target behind a cover. In one embodiment the target driving device can only be started while the locking signal is being emitted when shots hit the target.
