Abstract: 918,765. Tyre bead breakers. DUNLOP RUBBER CO. Ltd. Sept. 12, 1959, No. 31141/59. Addition to 918,764. Class 144 (1) The tyre bead breaker of the parent Specification is modified by the provision of one or more studs 35 in the gripping surface 33 of each upper jaw member 18 of the clamp, the or each stud having a tapering pointed extremity 37 to bite into the radially outer surface of the wheel rim flange without producing any elongated sharp edges therein. The stud may be welded to, or integral with, the surface 33, or, as shown, may have a cylindrical body part 36 which is a push fit into a recess 38 in the surface 33. The recess opens via a hole 39 to the opposite face of the jaw member 18 to avoid entrapment of air and to provide for ejection of the stud when worn.

Title: Improvements relating to apparatus for observing the sole surface of a foot
IPC: A43D1/02
Filed: 1928-10-26
Abstract: 315,165. May, J. Oct. 26, 1928. Optical instruments; anthropometrical appliances.-In apparatus for observing changes in the surface of the sole of a foot when resting on a plate b and subjected to a load and unloaded, a casing a below the plate accommodates a mirror c which is adapted to be withdrawn partly from the casing through an open end thereof, and it is then at such an angle to the plate that the desired observation can be made by looking into the projecting portion of the mirror. As shown, the open end of the casing is fitted with a hinged door to which the outer end of the mirror is pivoted, and in this way when the door is opened the mirror is brought out and brought to the correct angular position for the observation to be made. A projection n screens the mirror from light from the lamp c which is arranged in front of a platform g and covered by a frosted glass plate l. By the provision of an abutment o on the mirror and a spring contact-carrying arm k projecting up through a slot in the platform, the lamp circuit is automatically made and broken as the mirror is withdrawn from, and retired into, the casing. The sides of the mirror may be provided with hooks which, by engagement with guide-bars m, limit the forward movement of the mirror.

Abstract: 1395621 Ignition systems R C A CORPORATION 6 July 1972 [8 July 1971] 31590/72 Heading F1B With the ignition points 135 closed base current is provided to the transistor 125. Since no current is flowing initially in the circuit the potential across resistor 130 is zero and base current is also provided to the transistor 115 via the detection circuit 160. Accordingly both transistors are switched into saturation and current beings to flow through the series circuit comprising the D.C. source 111 transistor 115 winding 119 transistor 125 and resistor 130. As the current through the coil builds up the potential across the resistor 130 increases and when it attains a predetermined level the detection circuit 160 responds by cutting off the supply of base current to the transistor 115 causing it to turn off. With the transistor 115 off and the transistor 125 on (i.e. the ignition points still closed) the energy stored in the primary winding 119 sustains current flow through the series circuit including winding 119, transistor 125, resistor 130 and diode 150 when the current decreases sufficiently the drop in potential across the resistor 130 is detected by the detection circuit 160 which responds by providing base current to the transistor 115 causing it to turn on and recharge the coil to its desired energy level. When the ignition points 135 open base current is removed from the transistor 125 causing it to turn off at which point the energy stored in the winding 119 induces a high voltage in the secondary winding 121 which in turn provides the necessary ignition spark to the sparking plugs via the distributor.

Abstract: 1,163,049. Bi-stable circuits. SYLVANIA ELECTRIC PRODUCTS Inc. 11 July, 1967 [11 July, 1966], No. 31904/67. Heading H3T. A bi-stable circuit of the type comprising two cross-coupled elements has two switching circuits connected to one of the elements, one being responsive to concurrent signals at two input terminals to set the circuit and one responsive to a signal at one only of the terminals to reset it. Concurrent application of positive clock and data pulses to the emitters of transistor Q 4  diverts base current from the emitters to the collector rendering Q 5  conducting. This both renders an output transistor Q 7  conducting and also changes the cross-coupled bistable circuit Q 6 , Q 8  to the state in which Q 8  is non-conductive and Q 6  conductive. Switch-on of Q 6  is assisted by current flow to its base via Q 3  from the positive data pulse since Q 3  is rendered conductive by the clock pulse applied to its base via diode Q 1  and transistor Q 2 . At the termination of clock or data pulse the output transistor Q 7  is held conductive by transistor Q 6  of the bi-stable circuit. If a clock pulse now occurs in the absence of a positive data pulse, Q 4  remains non-conductive at its collector but Q 3  becomes conductive connecting the base of Q 6  to a low potential and thus switching the bi-stable circuit to the state in which Q 8  conducts. The output transistor Q 7  accordingly becomes non-conductive. Q 8  is connected to an output amplifier Q 9 -Q 11  or to a gate responsive to enable pulse and the output of a number of the circuits may feed a common OR gate.
