Title: Improvements in and relating to splices for multiple-ply fabrics
IPC: F16G1/04
Filed: 1936-01-23
Abstract: 459,331. Driving - belts; compound fabrics. CRUICKSHANK, R. F., and CRUICKSHANK, R. A., 540, Hastings Street East, Vancouver, British Columbia. Jan. 23, 1936, No. 2206. [Class 80 (i)] [See also Group VIII] The free end of a multiple-ply fabric is secured by removing the transverse fibres from the free end of a ply and cementing the remaining fibres to an adjoining ply. As shown, the invention is applied to securing the ends of a single length of fabric wound on itself to form a multiple-ply endless belt. The invention may also be applied to a splice for a multiple-ply belt, in which the ends of the plies are cut so that the joints between complementary ends of each ply are staggered in respect to the joints of adjoining plies. The weft threads are removed from the ends of the plies and the warp threads are teased out and cemented to each other and to an adjoining ply with rubber cement, which is then vulcanized.

Abstract: 765,568. Transistors. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 29, 1954 [Feb. 2, 1953], No. 2769/54. Class 37. [Also in Group XL (c)] A transistor element comprises a flat semiconductor element of one conductivity type in which zones of the opposite type exist, two of said zones being a short distance apart and each extending to one of two opposing surfaces of the element and a third thin zone extending between these surfaces. In Fig. 1, an N-type element has zones 1, 2 and 3 of P-type conductivity, each having an electrode e<SP>2</SP>, c<SP>2</SP> and b<SP>1</SP> respectively. The arrangement effectively provides a first transistor having emitting base and collector electrodes e<SP>1</SP>, b<SP>1</SP> and c<SP>1</SP> and a second transistor having electrodes e<SP>2</SP>, b<SP>2</SP> and c<SP>2</SP>. Electrode c<SP>1</SP> is the same as electrode b<SP>2</SP>. The distance between zones 1 and 2, and the thickness of zone 3 is small to provide transistor operation. Preferably the N-type material associated with electrode e<SP>1</SP> is of low resistivity, and that associated with c<SP>1</SP> is of high resistivity, but the functions and resistivities of these electrodes may be interchanged. A second electrode b 1 <SP>1</SP> may be provided on zone 3 for highfrequency operation. The element may be manufactured by seed growing the crystal to form zone 3 in an N-type element, and then diffusing indium to form zones 1 and 2. Fig. 3 shows an amplifying circuit employing the device described in Fig. 1, shown schematically as two transistors. Voltage supply source 8 connected between e<SP>1</SP> and e<SP>2</SP> supplies the biasing potentials and the signal 7 is applied to base electrode b<SP>1</SP>. An amplified output appears across resistance 10 in the circuit of collector c<SP>2</SP>. Fig. 4 shows an alternative circuit in which e<SP>1</SP> and c<SP>1</SP> are interchanged operationally, the first transistor being connected in " earthedcollector fashion, while the second operates as " earthed-emitter," so that high input and output impedances are provided.
