Title: Improvements in or relating to magnetic drum registers
Inventor: ROBINS JOHN MONTGOMERY
IPC: H04M15/04
Filed: 1958-05-02
Abstract: 866,272. Electronic counting apparatus. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. April 10, 1959 [May 2, 1958], No. 14109/58. Class 106 (1). A counter for telephone subscribers accounts records the accumulated received total of metering pulses on a magnetic drum in a code having a number of lower significance bits (the left-hand four in Fig. 1) in pure binary code, and other equi-weighted bits representing a higher value, so that a fault is less likely to cause a large error in the charge made. The value to be ascribed to each bit in the lower row is shown in the corresponding position in the upper row of the Figure. Fig. 3 shows the logical circuitry needed; an input pulse P sets a flip-flop MAN to give an output enabling clock pulses TA(1-4) in the first four digit positions to record a 0 (output SA) when a 1 is read to give a signal at SL, until a 0 is read to give a signal at SL when a 1 is written (output SB) and MAN is reset. After the first four bit positions 1's read are not altered. A bill for the subscriber may be calculated from the equi-weighted bits only, leaving the lower-significance bits as residue in the counter. A modification in which this residue consists of binary coded units and tens, and the equi-weighted bits are hundreds, is described, and the logical circuitry for the counter is illustrated.

Title: Method of improving or testing p-n junction characteristics in a semiconductor device
Inventor: MANKARIOUS RAMZY GUINDY
IPC: H01L21/288
Filed: 1969-03-18
Abstract: 1,248,124. Semiconductor devices. HUGHES AIRCRAFT CO. 18 March, 1969 [18 March, 1968], No. 14179/69. Heading H1K. [Also in Division C7] A conductive film is selectively removed from the N-type side of a PN junction in a semiconductor body by immersing at least the junction-containing part of the body in a deplating solution, reverse-biasing the junction and applying a deplating current which tends to pass preferentially between the solution and the N-type region. In the embodiment shown Si mesa diodes are formed by epitaxial deposition of relatively weakly N-type material on an N+ type Si wafer 10 and diffusion or ion implantation of B into the deposited layer to form a P + type region 12. An Au electrode is applied to the P+-type region 12 and an Ag heat sink pad 13 is electroplated thereon. The wafer is then etched to form a plurality of mesas, and this tends to cause the redeposition of Ag across the junction. The detrimental effect of this Ag is removed by selectively deplating from the N- type region as described above in a solution of potassium cyanide, potassium carbonate, " Sel Rex " (Registered Trade Mark) silver salts and water. This process also indicates diodes in which the junction is not satisfactorily formed, since such devices tend to deplate badly and may be discarded. The wafer is then diced. The invention is equally applicable to transistors, S.C.R.'s &c.

Title: Improvements in linkages for force transmission
IPC: F16H21/10
Filed: 1924-06-16
Abstract: 241,253. Lloyd, G. E. June 16, 1924. Link-work; Bowden mechanism. - For the transmission of force at one or more intermediate points in the length of a linkage, as in the simultaneous application of brakes on a number of coupled vehicles, a bell crank at each intermediate point has its fulcrum constrained only in the direction of the intermediate applied force, being free to move in the direction of the continued transmission of force through the linkage. As shown in Fig. 1, the force is transmitted through links A, T coupled by a double bell crank B capable of translational movement in the general direction of the linkage and of turning movement to exert intermediate lateral forces upon the parallel links Dr, Dl which, with a link L are coupled by T-shaped bars Sl, Su mounted on fixed pivots Pl, Pu. In Fig. 2 an arrangement is shown for simultaneously applying brakes on a number of coupled vehicles V1, V2, V3, means being provided whereby the brakes are applied with greater force on the rear vehicle for the time being. The bell cranks B1, B2, B3, through which the brakes are actuated, are coupled to the actuating means through Bowden cables or equivalent means C1, C2, C3 and are connected to the brake arms G by parallel links H so that they are capable both of translational and turning movement, only the latter being effective in applying the brakes. To the fixed pivot P of each parallelogram is pivoted a strut J which, under the influence of a spring K, is adapted to make the parallelogram rigid. The transmitting cable, such as C2, C3, being connected to the end of this strut, it is however normally drawn back against the floating fulcrum M of the bell crank thus allowing collapse of the parallelogram whilst clearance is being taken up, after which the bell crank turns about the fulcrum M to apply the brake. In the case of the rear vehicle V3, the strut J being free, is drawn into engagement with the parallelogram to render this rigid and in one with the bell crank B whereby a greater leverage is obtained in applying the rear brakes. A modification is described wherein the linkage is employed to free brakes applied by springs. In this case the bell crank on the rear vehicle acts with reduced leverage.
