Title: Improvements in and relating to electrical systems for controlling the operation of apparatus and magnitudes of variable quantities
IPC: G05B19/12
Filed: 1943-10-05
Abstract: 571,983. Follow-up control systems. DAVIS, N. R., and SUN-VIC CONTROLS, Ltd. Oct. 5, 1943, No. 16332. [Class 40 (i)] [Also in Groups XIX and XXXV] Temperature &c.-Apparatus is automatically controlled, or a quantity automatically regulated, in dependence upon a controlling quantity which may be time or another quantity, by means of a surface moved by the controlling quantity and carrying a coating or deposit of different conductivity from the surface. The coating co-operates with an electrical control member, which may move in a different direction in accordance with a controlled quantity, to change the conditions in the grid or control circuit of an electronic relay or oscillating valve governing the controlled apparatus or quantity. The coating or deposit may be continuous or broken, e.g. a line drawn by a graphite pencil on a paper chart which may be carried or driven by the clockwork actuated drum of a recording apparatus of known type. The cooperating member may be a conducting stirrup attached to a recording pen so as to make contact with the surface at a point laterally displaced from the pen. It may be the pen itself and it may be periodically lifted upon contact with the surface, if suitable time delay operation of the relay be provided. It may also be constituted by a coil or by two coils adjacent to opposite faces of the chart, their mutual inductance being varied by proximity to the coating, or it may constitute with the coating a variable condenser. As shown, the coating 9 is maintained in contact with a bar 10 which, with the pen 4, is connected across a resistance 30 on a series circuit of a condenser 28, resistances 29, 30 and transformer windings 25, 31 whereby the phase of the voltage and the grid of a valve 20 is varied in relation to the A.C. potential in the anode circuit. The latter circuit comprises a relay winding 24 normally insufficiently energized to open normally closed contacts 23 in series with the heating winding 21 of a furnace. The recorder movement 6 responds to the temperature of the furnace so that when contact is made between the stirrup 11 and the coating 9 the relay 24 opens the contact 23. The chart or coating may be replaced to obtain any desired programme control of the furnace temperature. The recording apparatus may be provided with a pencil in a suitable mounting whereby it may be positioned at will in or out of contact with the surface in any lateral position ; so that for example the controlled quantity may be maintained constant. An electric heater may be associated with the chart, e.g. in the drum, to combat high humidity conditions. Local heating means, such as a pair of heated rollers, may be used with the chart if colloidal graphite be employed.

Title: Improved electric signal counting apparatus
Inventor: JONES FRANK WILLIAM
IPC: H03K23/74
Filed: 1956-06-01
Abstract: 841,051. Counting-apparatus. COMMUNICATIONS PATENTS Ltd. June 1, 1956, No. 17038/56. Class 106 (1). A binary relay pulse counter is adapted to register the difference in number of pulses appearing at " additive " and " subtractive " inputs. The relays used are of the kind shown in Fig. 4 in which initial energization causes a spring-biased armature 33 to be attracted, a pawl 37 being arranged to step on a ratchetwheel 38 when the relay is de-energized, thereby changing over contacts operated by a cam 39 driven in response to the movement of the ratchet-wheel 38. The next energization and de-energization returns the contacts to their original state. A counting-chain, Fig. 2, comprises relays RL5-RL8. Impulss to be added appear at a terminal X, the first impulse energizing the relay RL5 to close contacts 5f/g and open contacts 5a/b, the next impulse energizing the relays RL5 and RL6 to close contacts 6f/g, open contacts 6a/b, open contacts 5f/g and close contacts 5a/b so that the third impulse energizes the relay RL5 only. Pulses to be subtracted appear at a terminal Y and are effective to energize such of the relays RL5-RL8 as may be reached over closed contacts a/b, the count being indicated by the state of the a/b or f/g contacts. Contacts h/j closed when the contacts f/g are closed and additional relay windings such as 22 enable the counter to be reset to zero and windings 22 enable an arbitrary initial count to be preset. The count may be indicated by lamps, a lamp being provided for each order and the lamps being energized over additional relay contacts (Fig. 5, not shown). In a further arrangement, Fig. 6, a voltage analogue representation of the count is obtained by supplying relay contacts 1e, 2e, 3e, &c. with voltages of 1 v., 2 v., 4 v., &c., such voltages as are supplied to denominations representing a binary " 1 " feeding over contacts 1d, 2d, 3d, &c., a summation amplifier 51 via equal resistances 49. Alternatively, the resistances may be weighted, equal voltages being supplied. Arrangements are also described (Figs. 7, 8, not shown) for reading out a digital representation of the count in either serial or parallel form, for example to a digital computer.
