Title: Improvements in or relating to methods of producing blocks of electrically connected thermo-electric elements
IPC: H01L35/34
Filed: 1962-08-16
Abstract: <PICT:0957855/C3/1> In making a block of electrically connected thermo-electric elements held in an insulating material and having their "hot" junctions located on one side of a median plane of the block and their "cold" junctions on the opposite side, the predetermined junctions at one or both sides of the median plane of the block are formed of electrically conductive bridges, preferably less than 1 mm. thick, by vapour coating of metal, e.g. at least one of Mo, Ni, Fe, Co, Cr, Cu, Al, and Ag.  As shown in Fig. 1, the block may comprise p- and n-conducting elements 1 and 2 embedded in an organic or inorganic insulating material 5.  The forming of bridges 6 by vapour coating may be performed on one or both sides with the aid of a metal foil mask 3 from an evaporator 4. For example, Mo, Fe, Ni, Co and/or Cr may be first vapour deposited, the bridges being subsequently thickened by vapour coating with Cu, Al or Ag. The thickening may be performed by electro-deposition, e.g. of Cu or Ni. An insulating layer of SiO, B2O3 or glass may be applied to the finished bridges. If the outer layer is Al, it may be subjected to anodic oxidation. Adhesion of the vapour deposited metal may be increased by tempering and diffusion.

Title: Improvements in or relating to means for indicating faults on electrically driven belt conveyor systems
Inventor: DENHOLM GEORGE
IPC: B65G23/00
Filed: 1952-12-17
Abstract: 743,258. Endless belt conveyers. WOOD & CO., Ltd., H. Dec. 17, 1953 [Dec. 17, 1952], No. 31964/52. Class 78 (1). A belt conveyer includes various faultindicating devices, responsive e.g. to belt slip, excessive temperature, a torn belt, and to material on the underbelt, each of these devices, except that for belt slip, operating a switch 2, 3 or 4 as a result of a fault to close the circuit of an indicator A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP>, and each switch in its non-operative position closing contacts in series with one another and with a common relay E, whereby when any device other than that responsive to belt slip operates, the relay is de-energized and prevents operation of the belt slip indicator. As shown, the belt slip indicator comprises a switch BP<SP>1</SP> electromagnetically closed by the voltage from a generator driven from a belt idler and adapted to open whenever the speed falls below a predetermined value. The motor circuit MC is broken if either relay E is de-energized through contacts E<SP>3</SP>, or relay H is de-energized by the opening of switch BP<SP>1</SP> through contacts H<SP>2</SP>, contacts G normally being open. If switch BP<SP>1</SP> is opened owing to belt slip without previous operation of the other fault indicating devices, the motor circuit MC will be broken and, as the belt comes to rest, a motionresponsive switch K will close, energizing a lock-off relay J through contacts H<SP>1</SP> and G<SP>1</SP> (the latter being normally closed) and opening contacts J<SP>3</SP> in circuit MC and holding itself in over contacts J<SP>1</SP>. Contacts J<SP>2</SP> also open in the circuit of a delay starter switch DS. Belt slip indicator D<SP>1</SP> is illuminated through normally closed contacts E<SP>1</SP> of relay E. If any of the other fault-indicating devices is operated before the belt slip indicator, contacts E<SP>1</SP> open preventing indicator D<SP>1</SP> from being illuminated when the belt slows down owing to opening of contacts E<SP>3</SP> in circuit MC. The closure of contacts E<SP>2</SP> of relay E ensures relay J being energized in case switch BP<SP>1</SP> does not open when the belt stops. To restart the conveyer after the fault has been rectified, relay E being reenergized, relay J must be de-energized by a re-set switch 9, contacts 9a of which open whilst the contacts 8 close, energizing a test relay F. The latter closes contacts F<SP>1</SP>-F<SP>4</SP> in all indicating circuits to check that the indicators are working. Switch DS is now pressed, this having a delayed opening of twenty seconds, whereby relay G remains energized until the belt has run up to speed. The closing of contact G<SP>2</SP> re-energizes motor circuit MC while the opening of contacts G<SP>1</SP> prevents re-energizing of relay J so that switch 9 may be released. Before contacts G<SP>2</SP> re-open owing to contacts DS opening, switch BP<SP>1</SP> is closed so that contacts H<SP>2</SP> maintain the circuit MC closed.

Abstract: 1,058,526. Arcing preventing in switches. SINGER CO. July 29, 1965, No. 32389/65. Heading H2B. [Also in Division G3] To prevent arcing at the contacts of a switch controlling a load, e.g. a portable electric tool, supplied from an A.C. source through the anodecathode circuit of a controlled rectifier, the switch has two pairs of contacts which are operated sequentially to apply the voltage of the source to the anode-cathode circuit of the rectifier in series with the load before applying it to the gate of the rectifier and to remove the voltage from the gate before its removal from the load circuit. The switch has an inherent delay time between the operation of the two pairs of contacts of at least one half-cycle of the A.C. supply so that the load current is always interrupted by the controlled rectifier becoming non-conducting and not by the opening of the switch contacts. Several embodiments are described including one in which the load is a motor having its speed controlled by a centrifugal switch driven by the motor and with its contacts in series with the gate of the rectifier.
