Title: Improvements in mountings for ballasts on fluorescent lighting units
IPC: H05B41/00
Filed: 1962-12-04
Abstract: 1,023,035. Releasable fastenings. E. BOSTONIAN. Dec. 4, 1962 [Dec. 5, 1961], No. 45774/62. Headings E2A and E2B. [Also in Divisions F4 and H1] A ballast is secured to a fluorescent lighting system by supporting means, which may be a lip engaging a groove in the body of the fitting at or set of prongs on the ballast engaging mating holes in a block on the body of the fitting, the prongs and holes serving also for electrical connections between the ballast and the fitting, and toggle locking means for securing the ballast in place. Fig. 4 shows a locking means consisting of an arcuate element 28 and a handle 30 pivoted on a shaft 32. A resilient safety catch 38 for the handle may be provided. In another form, a toe on the ballast engages a spring clip, the opposite end of the ballast bearing a yoke in which an arcuate element carried by arms on the body of the fitting and operated by a handle so as to press the ballast into place, engages. The locking means may also be a cam carried by the body of the fitting. The handle of Fig. 4 may be truncated and a slot to receive a screwdriver for use as a handle formed in it. The slot may alternatively be shaped so that operation can only be effected by a special tool. In a further modification, the ballast slides on rails on the fitting and carries an upstanding pin, on which is a bracket carrying a shaft, the opposite end of which passes through a hole in a bracket on the fitting, a helical spring being mounted on the shaft. An arm extends between the pin and a handle mounted on the fitting so that movement of the handle carries the ballast through the position where the spring is compressed to one where it is extended, thereby either locking or unlocking the ballast.

Title: Error Correction Circuit For Digital Recording Systems
IPC: G11C29/00
Filed: 1966-10-14
Abstract: 1,155,858. Digital record reading circuits; error correction. INTERNATIONAL STANDARD ELECTRIC CORP. 14 Oct., 1966 [21 Oct., 1965], No. 45942/66. Heading G4C. The threshold with which reading voltages are compared in a multi-channel read-out circuit may be reduced in the event of bad parity being detected. Each channel (1, 2 ... n) of a magnetic tape, drum or disc apparatus includes in its reading circuit a pre-amplifier 10, 11 or 12 (Fig. 1) a peak holding circuit 13, 14 or 15 including a capacitor 39 (Fig. 2) whereby the peak voltage input may be held for a predetermined period, a voltage comparator 16, 17 or 18 in which the input peak voltage is compared with a threshold voltage whereby a binary 1 or 0 output is produced accordding to whether or not said input voltage exceeds the threshold voltage, an AND-gate 19, 20 or 21 and a flip-flop 23, 24 or 25 forming one stage of an output register 22. The gates 19-21 are opened by a signal from a flip-flop 32 which is set to the 1-state by a signal generated by the coincidence at an AND-gate 29 of a good-parity signal on line 30 from a parity checker 26 connected in parallel to the voltage comparators 16-18 and an output signal from a delay circuit 27 also receiving signals from the comparators 16-18, the delay circuit 27 being provided to compensate for skew errors. If, as a result of receiving a weak input signal on one of the input channels, a bad parity condition is detected at the parity checker 26, a signal is issued on the line 33 instead of line 30 and a flip-flop 35 is set to its 1-state (after a delay as before) in place of the flip-flop 32. The error signal thus generated by flip-flop 35 causes the voltages stored on the capacitors in the holding circuits 13-15 to be increased, the "release" potential at terminal 43 (Fig. 2) being higher than any possible data input potential at terminal 41. As soon as a further one of the voltage outputs from circuits 13-15 reaches the said threshold voltage, the priority checking circuit 26 issues a good parity signal which by way of AND-gate 36 sets the flip-flop 32 to is 1-state and resets the flip-flop 35. After a short delay provided by a circuit 37 the flip-flop 32 is reset and the holding circuits 13-15 cleared (terminal 46 which is normally held at a sufficient potential to cause diode 47 to be back biased is grounded). The effective shift of the threshold voltage may alternately be achieved by changing the bias voltage of the comparators 16-18. The peak holding circuits may be modified (Fig. 4, not shown) to receive bipolar input signals. In a further modification (Figs. 5 and 6, not shown) the comparator circuits 16-18 are able to operate at two threshold voltages, the lower one being used to detect the occurrence of a character and the higher one for reading the character-as previously described.

Abstract: 1,141,375. Thermocouples. CORNELL AERONAUTICAL LABORATORY, Inc. 19 Oct., 1966, No. 46826/66. Heading H1K. [Also in Division G1] A probe for measuring the true temperature of a surface comprises a pair of thermocouples and a heater element. One of the couples is mounted next the surface while the other is so disposed that a temperature difference between the couples indicates heat flow into the probe from the surface. In operation any such difference causes the heater to be energized to eliminate it and hence reduce the heat flow to zero. In a typical case the couples and heater are of ribbon form and with intervening insulating films of resin or evaporated silicates form a laminar structure on the convex end of an insulating rod through which the leads to the ribbons extend. Suitable materials for the couples are iron-constantan, copper-constantan, and Chromel-Alumel (Trade Mark). Preferably the couples are connected through a 400c/s chopper to a temperature indicator and heater control circuit. On alternate half cycles the couples are connected in series opposition and on the intervening half cycles one of the couples is connected to the indicator. In a modified arrangement three couples are used, one continuously coupled to the indicator, and the others, detecting heat flow are connected in series opposition in the heater control circuit.

Abstract: 1435904 Alarm clocks; clocks combined with radios &c D A POLLINGTON 16 Jan 1974 [17 Oct 1972] 47841/72 Heading G3T [Also in Division H3] An adjustable electrical switch 5-8 including an electrically driven timing mechanism 4 is settable selectively to energize and de-energize a radio receiver 2 or to energize and de-energize a cassette tape replay device 3. As shown the arrangement is mains operated but it can be battery operated, the circuitry being transistorized. The radio 2 and/or device 3 can be turned on and off by switches 10, 11. A sleep control cam 7 can be adjusted to turn on a switch 8 and thus turn on the radio 2 and/or the tape device 3 as selected by the switches 10, 11 for a predetermined time while a listener is falling asleep. An alarm cam 5 can be adjusted to turn on the radio 2 and/or device 3 by closing switch 6 at a predetermined time to waken the user. A further alarm such as a buzzer may also he turned on in response to switch 6. The timing is obtained by an electrical clock which can be of digital type. The cassette unit may play a continuous loop of tape or alternatively a further tape unit can be provided for playing a continuous loop so as to provide a repeating wake-up message when the alarm operates. The cassette unit may be switched to record from the radio. A further timing and switching arrangement is disclosed in the drawing accompanying the complete specification (not shown) where "on" and "off" timing impulses are provided electronically or mechanically by means of cams. "On" impulses obtained by closing contacts (12 or 13) energize a relay (R1) which causes contacts (R1/1, R1/2) to close and supply via a selector switch (16) the radio 2 and/or tape device 3. "Off" impulses obtained by closing contacts (14 or 15) energize a relay (R2) which causes a normally closed contact (R2/1) to open so as to de-energize the relay (R1). The contacts (R1/1 and R1/2) of the relay (R1) then open and the supply is disconnected from the radio and/or tape device. With the radio 2 selected by the selector switch (16) and turned on by a timed impulse, the next turn-on impulse may be made to switch on the tape device 3 by momentarily depressing a pre-selector button (18). This energizes a relay (R3) which is held energized by operation of its contact (R3/1). Contact (R3/2) also closes to maintain power to the radio and contacts (R3/3) open. Now by moving the selector switch (16) to select the tape device, the radio remains on and when the "off" impulse occurs the relay (R3) is de-energized to open contacts (R3/1 and R3/2) to turn off the radio 2 and to close the contact (R3/3). The next "on" impulse then turns on the tape device 3. Similarly the radio can be selected to be turned on by the next impulse after the tape device has been turned on.

Closure of the switches is effected progressively owing to the trailer inertia so that at the commencement of retardation of the trailer the initial braking effect of the current applied at the input terminal is low, due to current reduction by the resistors and thereafter progressively increases the current to the brakes, to increase the braking effect as the inertia of the trailer causes the switches to be progressively closed. The brake operation is controlled by a pedal operated relay of the moving coil type. Each switch comprises a capsule into which one terminal of the respective resistor projects, the other terminal being connected to a bus-bar 21 common to all resistors. A resistor R 0  is provided by which the maximum value of the current is limited irrespective of the inclination of the switches I 1  to I 8 . The housing is formed of insulating material and has a V-shaped recess about which the housing may tilt, a U-profiled member 22 cooperating with the board 20 and engaging a rack 29 being provided to adjust the housing inclination.
