Title: Improvements in or relating to telemetering arrangements
IPC: G08C19/16
Filed: 1941-11-20
Abstract: 553,503. Electric signalling systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., RAYNER, T. R., and BURNS, G. A. Nov. 20, 1941, No. 14918. [Class 40 (i)] [Also in Group XIX] In a 'system wherein meter indications are given in accordance with the rate of impulsing from a substation, the impulses received within a predetermined time period are counted by a chain of relays which utilizes all the possible combinations and in effect converts the number into the binary scale. As shown, energy meters associated with the export and import power circuits at the substation control contacts me, mi the intermittent closure of either of which gives rise to a stream of long and short impulses in the line circuit 10, 11. The relay chain to which the impulses are repeated by relay R comprises seven pairs of relays 1A ... 7A, 1B ... 7B, A operating at the beginning of an impulse and B at the end, capable of counting up to 127 impulses, the combinations for the first 8 impulses being 1 2 3 4 5 6 7 8 1A 2A 2A,1A 3A 3A,1A 3A,2A3A, 2A,1A 4A. Long impulses are distinguished by slowoperating relay E which connects up relay CO of the magnetically-locking type disclosed in Specification 515,529, [Group XXVII]. Relays HMP, TP energize at the end of each time period, whereupon the setting of the relay chain is transferred to a storage relay group 1X ... 7X which connects appropriate ones of a set of graded resistances YA ... YG in series with an ammeter MTR, the chain being restored to normal. Relay CO controls the direction of current through the ammeter so that export power and import power are indicated on either side of the central zero. A change in the condition of relay CO immediately restores the relay chain and zeroizes the ammeter.

Title: Improvements in or relating to locking means for the gear casing doors or the like of textile drawing frames
IPC: D01H1/16
Filed: 1944-08-11
Abstract: 590,180. Textile drawing frames. GIBSON, W. Aug. 11, 1944, No. 15307. [Class 120 (ii)] [Also. in Group XXIV] In a textile drawing frame, particularly of the Eves double crank push bar kind, having a gear casing at each side with a pair of sliding doors, movable to an overlapping open position, and a stopping and starting arrangement, e.g., a beltshifter, an arrangement of locking means is provided for the doors so that no door can be opened when the machine is being driven and the machine cannot be started while a door is open. The sliding doors 4, 5, at the side of the frame where the operating handle of the starting and stopping gear is situated, are locked closed by a bolt 8, under the control of the operator, and when the machine is to be stopped, the shaft 6 is turned so allowing the rod 10 to be depressed against the spring 12 and past a curved plate 14. Once the doors 4, 5 have been slidden open, the bolt 8 is locked by the upper edges of the doors which engage against a shoulder 16 of the bolt to prevent the machine from being restarted until the doors are slidden to the closed position again. A similar mechanism for the doors situated at the side of the frame where the belt-shifting fork is positioned, is also included. The back of the frame is furnished with a hinged flap 23 and a top plate 24. Upon breakage of a sliver, an automatic stop motion comes into action leaving the broken sliver on the top edge of the top plate for easy piecing. The hinged flap 23 is maintained closed, when the machine is running, by the co-operation of a pin 28 with a notched disc 26, the pin being carried by a pivoted lever 29. The tail 31 of the lever 29 co-operates with a recessed locking bar 32, slidable by the operation of the stop mechanism, so that while the machine is running, the flap 23 cannot be opened and when the flap 23 is open the machine cannot be restarted. Attached to the bar 32 is a latch plate 33 which, in the " door-closed " position, co-operates with a keeper 34 on the flap 23.

Title: Improvements in electric pulse signal translating circuits

Filed: 1962-04-24
Abstract: 1,003,752. Automatic gain control circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 24, 1962 [June 29, 1961], No. 15433/62. Heading H4R. In an A.G.C. circuit for a pulse amplifier handling pulses of substantially constant repetition frequency but having gaps between trains of pulses due to the information content, the output of the amplifier is rectified and charges a capacitor which is discharged through one of two discharge paths having different discharge times, the potential across the capacitor being compared with a reference potential to provide a control signal to control the gain of the amplifier. The alternative discharge times are employed to give a comparatively short time constant for the A.G.C. circuit whilst the pulse signal train is being amplified and a long time constant in the gaps between signal trains so that the gain of the amplifier is held sunstantially constant over the gaps. Alternatively or in addition the short time constant may be employed during periods of disturbance, e.g. when the data processing system is being switched or in abrupt on-track/off-track reproduction in locating the transducer on the recorded track in a data storage equipment. Fig. 2 shows a pulse amplifier 18 preceded by a variable gain amplifier 14 which comprises common emitter connected transistors 42 and 43 whose collector loads include diodes 52 and 53. The gain of the amplifier is controlled by varying the current through diodes 52 and 53 thus varying the impedance they present to transistors 42 and 43. The gain control current is derived by rectifying the output of the amplifier 18 in fullwave rectifier 22, the output from which charges capacitor 72 through charging resistor 71. Capacitor 72 is normally discharged through high resistor 74 with a time constant equal to a multiple of the periodic time of the pulses, the time constant may be reduced, e.g. during switching of the data processing system, by turning on the normally cutoff transistor 90, e.g. by operating switch 94. The voltage appearing across capacitor 72 is applied, via emitter follower 78, to a voltage comparison circuit where the capacitor voltage is compared with a reference voltage in transistor 82, the collector current of the transistor being fed to the diodes 52 and 53 in the variable gain amplifier 14. An alternative form of the invention is shown in Fig. 3 in which the rectified output of amplifier 18 charges capacitor 72 through emitter follower 104 and is also applied to hold transistor 112 cut off, this holds transistor 116 cut off and allows transistor 118 to conduct and provide a relatively short discharge time for capacitor 72. During gaps between pulse trains however, transistor 112 conducts switching on transistor 116 which in turn cuts off transistor 118, thus increasing the discharge time constant of capacitor 72 so that the gain of-the variable gain amplifier 14 is held substantially constant until the following pulse train arrives.
