Title: Improvements in electrostatic printing
IPC: G03G15/10
Filed: 1964-11-18
Abstract: 1,076,625. Printing apparatus. RESEARCH LABORATORIES OF AUSTRALIA PTY. Ltd. Nov. 18, 1964 [Nov. 19, 1963], No. 47033/64. Heading B6C. In an electrostatic printing machine using liquid developer containing toner particles, the latter is retained on the master such that at the transfer or printing station the receiving web or copy material is not in direct contact with the master, transfer of the image thereon being effected by an electric field acting through the developer liquid. In the apparatus shown, a cylinder mounted master 2 of photo-conductive material imaged with electrical insulating material and electrostatically charged at the transfer station is subjected to a light source 19 to de-energize the non-image areas prior to passing over a developer bath 11 in which three driven earthed rollers 7, 8, 9 apply liquid developer to the imaged areas. The rollers 7 and 8 do not touch the master 2 but are spaced therefrom leaving gaps 13 and 14 respectively. The transfer station comprising a spring-loaded web receiving roller 4 is located adjacent the developer bath 11 such that the master is still covered with liquid developer to a thickness sufficient to bridge the gap 17 between the roller 4 and the master cylinder 1. A voltage is applied across this gap to simultaneously transfer the image from the master on to the web 6 and re-charge the master prior to its subsequent use. A small electrical bias is applied at the developer station to prevent particles in the developer liquid from contacting the non-image areas. The roller 4 may be placed near the cylinder 1 within the 60 degree arc shown in Fig. 1. Both the cylinder 1 and roller 4 are belt-driven from a common source, the belts driving the cylinder being at each end and contacting the roller 4 such that the space 17 is in effect ordained by the thickness of the belts.

Title: Semiconductor device
IPC: H01L29/06
Filed: 1965-11-08
Abstract: 1,116,384. Transistors. MOTOROLA, Inc. 8 Nov., 1965 [30 Nov., 1964], No. 47275/65. Heading H1K. In a junction transistor suitable for use at high frequencies a lock region of the same conductivity type as the base zone is embedded in the collector zone. It is spaced from the collector junction so that with increasing collector voltage the depletion layer reaches it before it reaches the emitter zone. Its effect is to prevent further expansion of the depletion layer into the part of the base zone in front of it with further increase in collector voltage. As shown in Fig. 2 the lock layer 20 is of greater lateral extent than the emitter zone 11. This embodiment is made by first forming layer 20 by diffusion into one face of an N-type wafer, or by epitaxial deposition in an etched aperture therein. This is then buried beneath a further epitaxial layer of P-type. Finally the base region is formed by epitaxial deposition and the emitter produced by diffusion into this. In an alternative embodiment the lock region has an extension to the surface and is provided with an electrode. In this arrangement the gain of the transistor, which is substantially independent of the collector voltage once the depletion layer has reached the lock layer, may be varied by a signal applied to the lock layer, or the input signal may be applied to the lock layer using a fixed emitter bias.

Abstract: 1,255,753. Curing epoxy resins. CIBAGEIGY A.G. 26 Sept., 1969 [8 Oct., 1968], No. 47615/69. Heading C3B. Epoxy resins are cured by means of acylureas of formula in which R<SP>1</SP> and R<SP>2</SP> are C 1-3  alkyl groups and n = 1 or 2. From 0.2-0.7 equivalents of acylurea may be used per epoxide equivalent of the epoxy resin. The mixture of resin and curing agent is stable at room temperature. It may be advanced to the partially cured fusible "B- stage" by controlled heating. In curing the temperature is raised slowly in the range 120- 150 C. to avoid overcure. A typical curing programme is 3 hours at 120 C., 1 hour 130 C., 1 hour 140 C. 12 hours 150 C. and 34 hours 170 C. Examples relate to the curing of diglycidyl ethers of bisphenol A with N-monoacetylurea, N,N1-diacetylurea and N,N<SP>1</SP>-dipropionylurea.

Abstract: 1468280 Refrigerating BORG-WARNER CORP 12 Nov 1974 [5 Dec 1973] 48979/74 Heading F4H In a continuous cycle absorption refrigerator substantially similar to that described in Specification 1,300,704 which utilizes lithium bromide solution as absorbent and wherein the absorption cycle may be suspended and the absorber 40 operates as a condenser to liquefy the refrigerant vaporized in the evaporator 34, an exterior auxiliary receiver is replaced by a pan 150 within the evaporator-absorber shell 26 to act as a sump for storing the flow of absorbent solution during cessation of normal operation. The pan has a trough 154, Fig. 2, thereabout to intercept refrigerant and deliver it to the refrigerant circulation system. In normal operation, the flow of solution from the absorber 36 to the pan overflows the trough to pass into the lower portion of the shell for circulation by the solution pump 72 to the absorber sprays 38 and generator 24 but during cessation of normal operation the trough intercepts the refrigerant which is carried by lines 158, 160 and an ejector 164 to the refrigerant pump 92 for introduction into the evaporator sprays 30. A valve 170 controls operation of the ejector by preventing flow of motive fluid from the refrigerant pump 92 during abnormal operation.

Title: An Amplifier with Two Separate Channels
IPC: H04M9/00
Filed: 1966-11-04
Abstract: 1,169,906. Directional switching. GYLLING & CO. A.B. 4 Nov., 1966 [16 Dec., 1965], No. 49567/66. Heading H4R. In a loud-speaking telephone set having separate receive and transmit amplifiers, the receive amplifier is normally (i.e. when no signals are incoming to or outgoing from the set) almost fully operative while at the same time the transmit amplifier is almost fully blocked. If an incoming signal appears, a portion of it is derived at point P2 in the amplified chain and after further amplification at Fst2 is applied to a voltage comparator RA. A negative-going control signal is thence obtained on lead RL for increasing the gain of the receive amplifier DP, DS to its maximum value and for simultaneously reducing the gain of the transmit amplifier FP, FS but without actually cutting the latter off. A signal from the microphone M causes a positivegoing control signal to be obtained on RL with opposite effects to those just mentioned. The comparator uses a rectifier/resistor network (Fig. 2, not shown), for deriving the control signals. The transmit amplifier (Fig. 3, not shown), utilizes two stages of R-C coupled transistors each of which includes an individual control (switching) transistor in its emitter circuit. The receive amplifier (Fig. 4, not shown) comprises two stages of transistors with a # filter located between them. Each leg of the # incorporates a control transistor. The control lead RL is connected to each of the four just-mentioned control transistors and one transistor of each control pair is biased so as to be never cut-off whereby the required result, of minimizing amplifier gain without actually fully blocking it, is obtained.
