Title: Magnetic a/d encoder
IPC: H03M1/00
Filed: 1965-11-29
Abstract: 1,079,084. A/D converters. GENERAL PRECISION Inc. Nov. 29, 1965 [Jan. 6, 1965], No. 50603/65. Heading G4H. A shaft position encoder comprises a disc 20 of grain oriented anisotropic barium ferrite having code tracks 26, 28, 30 formed by magnetizing with the same polarity discrete portions near each face of disc 20. Each track is sensed by a magnetic core 54 having an interrogating winding 56 and an output winding 58. When a core 54 is adjacent a magnetized portion of a track, the magnetic flux emanating from the track saturates the core and no output is obtained from winding 58. Additional concentric continuous tracks 53 prevent flux from one track wandering towards an adjacent track. The least significant track may be formed by alternately oppositely polarized segments with narrow non-magnetized areas between them, Figs. 9-11 (not shown). The output of the sensing core varies continuously as the track moves past, and a squared output is obtained from a threshold device.

Abstract: 1,185,350. Sampling circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 6 Nov., 1968 [9 Nov., 1967], No. 51098/67. Heading H3T. [Also in Division G1] A sampling gate is enabled by a control pulse derived from the peak of the signal to be sampled is opened by the next timing pulse and closed and disabled by a succeeding timing pulse. In Fig. 3 the control pulse at the base of T9 opens a gate D1, D2 and changes the state of a bistable circuit T5, T6 to hold the gate open. The next timing pulse at D1 changes over a bistable circuit T7, T8 and this opens the sampling gate, not shown. The following timing pulse restores T7, T8 and this closes the sampling gate and restores T5, T6 so that gate D1, D2 is closed. The control pulse is derived from the peak of the signal to be sampled by differentiating the signal and detecting zero crossings by means of a Schmitt trigger. The circuit is used to sample signals modulated on a carrier. These are detected by a diode D, Fig. 2, and the resulting output is filtered by means of a capacitor C1 and a capacitive feedback amplifier T3, T4.

Abstract: 1369482 Alarm systems HONEYWELL Inc 3 Nov 1971 [28 Dec 1970] 51208/71 Heading G4H An alarm system for indicating abnormal operation of a control network having a central station and a plurality of remote stations comprises a logic circuit 48 in which delayed signals from keyboard or programme apparatus 15 denoting a command are processed with signals from a remote station denoting the effect on the remote equipment of the command message to operate indication or alarm apparatus 21 according to the response of the remote equipment to the command message. Signals of the form shown in Fig. 2A are respectively sent via transceivers 13, 14 from the central station to the remote station, and from the remote station to the central station. The first signal causes interface apparatus 22 to operate equipment such as a relay-operated fan motor 24 whose subsequent operation is detected by a sensor (switch) 25; the second signal informs the central station of the subsequent operational state of the equipment. The data 53 from the remote station is combined with time-delayed signals 50 from the keyboard 15 in the logic circuit 48 shown in Fig. 3: this comprises BCD to decimal converters 70-74 which are selectively energized by the input signals 50, 53 to yield one of possible outputs 62-65. When the second signal (input 53) is first compared with the time-delayed signal (input 50) the "new command" input thereof is set to 1 and if the motor 24 is incorrectly on or off, this is indicated by new alarm apparatus 62; in subsequent comparisons of the two signals both the inputs 50 are set to 0 and old alarm apparatus 63 operates instead of apparatus 62. Correct functioning of the system is indicated by apparatus 65 in either case.

Abstract: 1534524 Battery testing EASTMAN KODAK CO 19 Dec 1975 [24 Dec 1974] 52070/75 Heading G1U The voltage across a battery 3 under test is monitored 10, 11, 12, by depressing a key A and a timing circuit 2, 13, 4, ensures that a load 5, 6, 14, which is applied across the battery when the key A is depressed, is removed a fixed (but adjustable 13) time after the key is depressed unless the key is released before this time expires. When the key A is depressed a Schmitt trigger 4 immediately assumes its off state and renders a transistor 5 conductive, thereby applying a load 6, 14 - which simulates a real load - across the battery. The on-load battery voltage is then compared 11 with a Zener 10 reference voltage, and if the battery voltage is sufficiently high a lamp 12 is not lit. If the battery voltage is too low however, the lamp 12 is lit. While the key A is held depressed a capacitor 2 charges, via a resistor 13, and eventually the Schmitt trigger 4 will turn on and remove the load 6, 14 whereupon the lamp 12 will light. A non-electric timer (e.g. pneumatic) could be used, and the circuit is said to be particularly useful in the field of photography.

A primary cell comprises (a) a consumable metal anode; (b) a cathode comprising a gas chamber or labyrinth having an inlet and an outlet and formed from a sheet of material cut out and covered on at least one side with a microporous sheet material lined with a catalyst layer and a conductive layer; and (c) an electrolyte container. In a particular embodiment, Fig. 1, the cathode comprises frame 10 having the sheet material 11 folded over it. The microporous material may be PVC. The conductor may be silver. The gas, air or O 2  under pressure, is fed in via duct 21 and out via the corresponding duct on the opposite side. The frame 10 may be made of metal or metal coated or current may be withdrawn from nickel grids backing each side of the microporous sheet.

A deep fat frying apparatus has a main tank 1 divided into one or more compartments 6 by removable partitions 5. The compartments are of generally semicircular base section and a rotational flow is induced by, for instance, tangential oil jets 7. Oil is drained from within the partition 5 which it enters by means of sieve-like holes 28, by pipes 8, at a rate approximately equal to the discharge from the jets 7. An overall flow is promoted by the additional jets 24 and drain pipe 25 and is helped by the conveyer 16. The fat is heated in an external circuit before discharging from the jets and the extra jets 19 are for heat control purposes. The conveyer 14 removes the products and additionally scrapes clean the outlet sieve plate 26 and ejects the scraped matter. An overall cover 2 collects steam from the product and builds up a slight excess pressure due to the baffle plates 20a and 20b and the exhaust valves 22 and 23, thus preventing the ingress of air which would allow oxidation.
