Abstract: 827,985. Gearing for stopping machinery. MITCHELL CO., A. J. Sept. 18, 1956 [Sept. 22, 1955], No. 28474/56. Class 80 (2). [Also in Group VII] In apparatus for feeding a succession of buttons to a button sewing machine and for controlling the operation of the latter a gear 90 is journalled on a cam-shaft 80 and meshes with a gear 88 fast with a driving-shaft 84. A hub 94, fixed to shaft 80, slidably carries a driving- pin 96 spring-biased into driving engagement with one of a series of holes in gear 90. A lever 100, biased towards shaft 80 by a spring 102, carries a cam 106 adapted to co-operate with the head of pin 92 to draw the latter out of engagement with gear 90, the head then engaging a stop 108 on lever 100. A lever 110 carries a similar cam 112 and stop 114 which are displaced 90 degrees from cam 106 and stop 108. Lever 110 is held by a latch 116, against the bias of a spring 118, in a position to engage the stud head. At the commencement of a cycle of operations, when lever 110 is in the unlatched position, lever 100 is drawn downwardly by a treadle and a rod 104 to release pin 96 for driving shaft 80. A cam 160 on shaft 80 then coacts with a roller 162 on a lever 120 to raise a rod 164 to engage the driving clutch of the sewing-machine, and a cam lug 166 on shaft 80 acts on an extension 168 of lever 110 to move the latter to the latched position. Shaft 80 is stopped by cam 112 after rotating through 90 degrees, roller 162 and extension 168 then being clear of cam 160 and lug 166 respectively. Upon completion of the sewing operation rod 164 is drawn downwards automatically, whereby a stud 124 on lever 120 is engaged with latch 116 to trip the latter for freeing pin 96 to drive shaft 80. If lever 100 has been released, shaft 80 will be stopped in its initial position by cam 106. If, however, lever 100 is held depressed, shaft 80 will be stopped once in each revolution by cam 112, and a succession of buttons will be fed and sewn on automatically.

Abstract: 1517235 Printed circuits SIEMENS AG 9 July 1976 [16 Sept 1975] 28606/76 Heading H1R In a printed circuit board (Fig. 3) an insulant substrate 1 covered on each side with copper foil 2 having througholes 3. A copper layer 4 is then electrolessly deposited over the foils and the bore walls and electrolytically reinforced, and the sides of the board are coated with positive photolacquer 5 removed at areas 50 by exposure and development. The remaining photolacquer serves as a mask through which areas 50 are coated electrolytically with a copper layer 6 and a solderable etch resistant, e.g. tin or lead/tin metal layer 7. Thereafter the photolacquer layer 5 is again exposed and developed to leave areas on the plate to provide a mask, protecting the portions of foils 2 required to form conductor paths after etching (Fig. 4, not shown) by e.g. ammoniacal sodium chlorite not attacking layer 7, so that conductor paths 20 and solderable areas 21 remain (Fig. 5, not shown). The conductor paths 20 are passivated by immersion in a solution of liver of sulphur to provide a surface solder stop layer of copper sulphide leaving layer 7 uneffected, so that when components are soldered to the board (Fig. 6) only connecting wires 8, the metallic layer 7 of holes 4, and soldering areas 21 are wetted with solder at 9. Passivation may alternatively be effected by copper colouring solutions depositing copper or copper alloys with solder stop properties.

Abstract: 796,676. Electric analogue calculating systems. WESTERN ELECTRIC CO., Inc. Oct. 7, 1955 [Oct. 20, 1954], No. 28633/55. Class 37. [Also in Group XXXIX] In a circuit for obtaining a voltage V8 proportional to the quotient V1/V2, the voltages V1, V2 are applied via resistors R respectively to diodes 56, 57 which have exponential current/ voltage characteristics so that the voltages V3 and V4 at the grids of valves 51, 52 are proportional to the logarithms of V1, V2, respectively. By the cathode follower action these voltages are repeated as V5, V6 on the cathodes of the valves, and this voltage difference is applied to the exponential diode 58 to produce a current i7 proportional to the ratio V1/V2. The output is derived as a voltage V8 developed over a small anode resistor R1. The Specification contains detailed mathematical analysis of the circuit which is used in a speech current analyser (see Group XXXIX).

Title: Improvements in wheatstone bridges for the measurement of electrical capacity
IPC: G01R17/00
Filed: 1925-11-14
Abstract: 252,990. Campbell, A. Nov. 14, 1925. Addition to 244,596. Capacities and power-factors, measuring.-The variable mutual inductance claimed in the parent Specification is employed in an alternating-current wheatstone bridge for the measurement of the capacity and powerfactor of a condenser. In two arms of the bridge are placed similar inductive coils H, K, one or both of which are secondary coils of the mutual inductance. In series with the coils H, K are equal non-inductive resistances P, Q, which may be fixed or simultaneously variable. Equal ratio resistances R, S are connected as usual, and between their junction F and the slider of a potentiometer rheostat B is connected a source A of alternating current and the primary windings T, U of the mutual inductance. The condenser C to be tested is connected in parallel with the resistance Q and balance is restored by adjusting the mutual inductance until a null indication is obtained in the telephone of vibration galvanometer G. Then approximately the value of the capacity C = L/Q<2>, where L is twice the value of the mutual inductance. The values of P, Q may be inversely proportional to the square roots of the desired multiplying factors, for example #1000, 10, #10, 1 so as to give multiplying factors of 0.001, 0.01, 0.1, and 1 respectively. The potentiometer resistance B provides a fine adjustment of the resistance balance, and may be provided with a scale from the readings of which the power-factor may be deduced. In order to compensate for the slight increase of inductance in one arm and decrease in the other due to adjustment of the slider of the resistance B, a compensating variable inductance or a coil in the primary circuit of the mutual inductance may be mechanically coupled with the slider. Alternatively the potentiometer resistance B mav be replaced by a constant inductance rheostat in one arm of the bridge. When two condensers are to be compared, one is placed across each of the resistances P, Q, the difference of their capacities being measured. The ratio arms R, S may be unequal, the ratios of the resistances P, Q being correspondingly altered.
