Filed: 1971-06-15
Abstract: 1350421 Electro-photographic element MINOLTA CAMERA K K 15 June 1971 [15 June 1970] 28042/71 Heading G2C An electro-photographic element comprises a conductive base, two photo-conductive layers of different sensitivities, one layer comprising a uniform layer and the other layer being coated on the uniform layer as a pattern of discrete areas, and a transparent organic layer overlying the two layers. The first photo-conductive layer forms a rectifying junction with the base. In an embodiment, a polyester film having an aluminium film thereon is oxidized to give a layer of Al 2  O 3  and then vacuum coated with amorphous selenium. A mesh screen of stainless steel is attached to the surface of the selenium and an alloy of Se-Te evaporated therethrough. The screen is removed and a solution of polyvinylcarbazole, diphenyl trichloride and monochlorobenzene is applied to the surface. In other embodiments the base-plate is glass coated with Al or an aluminium plate coated with Al 2 O 3 . The first photo-conductive layer may be As 2 S 3 , or alloys of S with As or Sb whilst the other photoconductive layer may be alloys of Se with As or Sb.The organic layer may be a polyimide resin, polyvinyl-naphthalene or polyvinyl-malachite green. A semi-conductive rectifying layer may be interposed between the base and the uniform photo-conductive layer.

Abstract: 1,214,023. Multiplex speech synthesizer. INTERNATIONAL BUSINESS MACHINES CORP. 14 June, 1968 [29 June, 1967], No. 28321/68. Heading H4R. In a speech synthesizer providing simultaneously a plurality of speech outputs from a computer DR, Fig. 1, spectrum signals are transmitted in T.D.M. over a path MSK and excitation signals are transmitted over separate paths EXC 1-m  firstly to be applied to a delay network producing a chain of N pulses spaced #t for routing to the appropriate speech channel through a distributer MDEX, and secondly to be applied through logic and repeater circuits to control the separation of the spectrum function signals for application to the respective group of modulators pertinent to the channel. This latter is achieved by pulses from a tapped delay line VXT 1 , Fig. 5, connected in the respective excitation pulse paths opening gates T5 11-1n  to pass the spectrum data from MSK via two stages of storage SP: digital to analogue converters DAW and smoothing circuits GL 0 . Repetition of the excitation function pulses to open in conjunction with repeated excitation pulses from MDEX the m gates Ti1-Tin, Fig. 3, leading to the modulator Mil-Min of modulator set MSI is effected by one of a number of repeaters REPI-K, Fig. 6, through an OR gate OT1 and an AND gate UTREP the repeated signals being transmitted to OR gates OT 2  via another set of AND gates UTA 11 - UTA 1m . An incoming pulse on EXC1 opens AND gate UT11 to actuate a bi-stable multivibrator MM11 which opens AND gate UTA11 to pass N pulses at #t intervals from repeater 1 which has been activated by the same input pulse through OR gate OT1.

A dialysis device, e.g. for purifying blood, consists of semipermeable diaphragms 10 and 11 arranged in flat parallel relationship or in spiral shape with spacer members 12 between every other pair of adjacent layers of diaphragm, the spacer members having elevations 4 and 15 which co-operate to bring the two layers of diaphragm between adjacent spacer members into mutual engagement at defined intervals and lesser elevations 18 and 19 maintaining the layers of diaphragm a definite distance apart at points between the points of mutual engagement. The elevations 18 and 19 have small end surfaces 20 and 21 compared with end surfaces 16 and 17 of elevations 14 and 15 such that while the space 23 containing blood has its volume appreciably reduced the area utilizable for diffusion is not greatly reduced. Purifying liquid, e.g. a salt solution, circulates in the spaces 22 between the elevations and the diaphragms with which the impurities diffusing through the diaphragms are removed. Inlet and outlet channels for the blood are provided at opposite sides of the device. Each channel is connected to a nozzle 6 (Fig. 1) at the exterior of the device and the channels have lens-shaped diversion member (26) (Fig. 4, not shown) provided between the spacing members and the diaphragms 10 and 11. These have narrow diversion tubes (27) through which blood passes to spaces 23. The salt solution is supplied and removed through nozzles 7 and 8 (Fig. 1). The elevations may be made so resilient that if the pressure in the salt solution decreases the entire device is compressed.

[Also in Group XXV] An upper arc of the outer skin 1 of an animal intestine is prised away from the internal layer 4 by diverging guides, e.g. spring wire loops 13 and 15, entered between the layers at the arc only and over which the intestine is then drawn. The upper arc-like part then comes against radial knives 11 which cut the arc into longitudinal strips 25 suitable for racket strings or surgical sutures. The lower part 27, Fig. 4 of the intestine passes out below as a complete tube of internal layers partly covered with the under arc of outer layer, which tube is suitable for sausage skins. During this process the intestine is held stretched by a third loop 17 of wire at right angles to the previous loops 13, 15. The device comprises a body part 3 from one end of which project the loops. The spaced radial knives 11 are secured on the body to which is attached a guide 7 at the other end through which the strips are pulled. The lower part 27 may thereafter also be cut into strips. Various dimensions and shapes for the loops are given.
