Abstract: 1376442 Testing logic circuits MARCONI CO Ltd 20 Jan 1972 [15 April 1971] 9477/71 Heading G1U [Also in Division H3]  Test signals corresponding to desired logic 0 and 1 levels are generated at the output 10 of a summing amplifier 1 by applying to the input 4 a first voltage corresponding to the 0 level and, via a gate 5 a second voltage equal to the difference between 0 and 1 levels. As described, a programmed tape sets a bi-stable 21 to a desired one of the 0 and 1 states so that the input to amplifier 1 is either the 0 level or the sum of this level and the difference between 0 and 1 levels. This voltage is applied to output 10 to which is connected a logic circuit to be tested. Upon opening switches 9, terminal 10 receives a signal corresponding to the response of the logic circuit and this is compared in a comparator 16 with the desired response applied to terminal 14 by the magnetic tape. Erect and inverted outputs of the comparator are compared in a modulo 2 adder 20 with the data condition for bi-stable circuit 21 and a discrepency causes a bi-stable circuit 30 to operate an alarm.

Title: An improved circuit tester for testing the electrical circuits of motor vehicles and the like
IPC: G01R31/00
Filed: 1950-04-19
Abstract: 684,858. Electrically tripped switches. FLYNN, G. April 19, 1951 [April 19, 1950], No. 9581/50. Class 38 (v) [Also in Group XXXVI] An instrument for testing the circuits of power units including batteries and starters comprises an ammeter connected between two terminals in parallel with a manually-operated switch-controlled by-pass conductor, the two terminals being adapted to be connected between the positive side of the battery and earth. In the construction shown in Figs. 2 and 4 an aluminium casing 12 consists of an ammeter portion 12a and a switch portion 12b connected by channels 12c so as to form an enclosed space to accommodate the hand. In the portion 12b is mounted a test switch comprising a pair of resilient contacts 13 mounted on an insulating block 14. An overload coil 15 connected in series with the battery and dynamo is mounted on an insulating block 16, the blocks 14, 16 being fixed to the casing. Slidably passing through the block 16 is a brass rod 17 carrying a contactor 18. Loosely threaded over the rod 17 is an iron armature 19 which rocks between a pair of transverse parallel pins 20 so that in its inclined position the bore of the armature grips the spindle. The rod 17 is fastened at one end to a yoke 21 which slides in recesses in the blocks 14,16 and is operated by a knob 22. A compression spring 23 keeps the switch normally in the closed position, the contacts 13 being connected to the ammeter. When a test is to be made the knob 22 is pushed to the left, opening the switch. The armature 19 is rocked towards the vertical so that the rod 17 passes easily through it. On releasing the knob 22 the spring 23 tends to move the rod 17 to the right and so rocks the armature 19 so that its bore jams the rod 17 and holds the switch open. If the dynamo current exceeds a predetermined value the coil 15 attracts the armature 19 into a vertical position thereby releasing the rod 17 and closing the switch, which short-circuits the ammeter. In a modification, Fig. 7, the switch is housed in the casing 12a and is operated by a "pull" in the hand grip portion 12b. The contactor 24 of the switch is rigidly connected to a rod 25 slidable in a tube 26, which is slidable in the inner side of the portion 12a. One end of the tube 26 is ridigly connected to a grip 27 forming a main portion of the inner wall of the portion 12b, a spring 28 maintaining the switch normally closed. Mounted on the inside of the grip 27 is a hinged armature 29 carrying a detent 29a which normally engages a recess 25a in the rod 25 and locks it to the tube 26, so that the rod 25 and tube 26 move as one unit. To make a test the operator squeezes the grip 27 thereby opening the switch. If too high a current passes through the coil 15 the armature 29 is attracted into the position shown and withdraws the detent 29a from the recess 25a. The rod 25 is released and closes the switch under the pressure of the spring 28.

Abstract: 576,991. Bearings; lubricating. WILLYSOVERLAND MOTORS, Inc. May 19, 1944, No. 9699. Convention date, June 17, 1943. [Classes 12 (i) and 12 (iii)] A journal bearing is intermittently flushed of any foreign matter by periodically venting one of the lubricant channels. Fig. 3 shows in sectional view a crankshaft bearing for an internal-combustion engine the upper bearing portion 30 of which is formed in a web of the cylinder bloc 10 and the lower portion by a cap 31 bolted thereto. The cylinder bloc is formed with ducts 60, 62 communicating through a hole 63 in the upper liner of the bearing through which lubricant is supplied under pressure to a groove 66 on the inner surface of the liners the groove 67 in the lower liner of the bearing terminating short of a vent hole 70 as shown in enlarged plan view Fig. 4, which hole is open to the crank case 28 providing the oil sump. The hole 70 opens to an enlargement 73 formed in the bore for the capretaining bolt 32 and a discharge duct 71 opens from such enlargement. The crank shaft journal is formed with a duct 78 leading to the adjacent crank pin 75 so that oil is supplied thereto from the groove in the liner. As the end of the duct 78 passes the vent hole 70 during each revolution the foreign matter, which tends to collect in the end of such duct 78 by its passage over the end of the groove 67 of the lower liner, will be flushed out since the oil in the duct 78 will be relieved of pressure. The lubricant is drawn from the crankcase sump through a pivoted floating filter by a pump driven from the engine camshaft Fig. 2 (not shown). A further groove 85 in the liner supplies lubricant through a shaft duct 86 Fig. 1 (not shown) to a chain drive for the engine cam shaft.

[Class 118 (ii)] [See also Group XIX] A recorder for use in echo-sounding comprises a stylus driven round a circular path by a constant-speed motor through a variable speed device whereby records may be made either (e.g.) in feet or fathoms. Means are also described for varying the time when the initial sound is emitted in relation to the time when the recording point moves on to the record strip. The recording point 50 is carried by an arm 51 secured to a continuously-rotating disc 51A. The record may be made by electro-chemical means on a strip arranged as described in Specification 448,331. The point 50 is normally connected by a slip ring to the echo-sounding mechanism, but at predetermined intervals a cam closes a switch to connect the point to a commutator to make the dotted lines 64 forming a scale. The disc 51A is driven from a motor 54, Fig. 4. through variable-speed mechanism 53 which may also drive the record strip through a connection 81. The emission time is varied by turning a knob 68 on a shaft 69 carrying brushes 67 which are thus moved round a drum 66 having a conducting segment and being driven from the disc 51A, the brushes 67 being connected to the sound emitter. Another arrangement for obtaining this variation is shown in Fig. 5. A drum 71 rotates with the disc 51A and one emitter brush 77 bears on a conducting ring 75 on the drum, the ring being connected to a contact 74. Another contact 73 is connected to a series of six contacts 72 co-operating with the other emitter brush 76. The contacts 73, 74 are bridged once in each revolution by brushes on a normally stationary bar 79, the angular position of which is adjusted by a knob 80.
