Title: A method of increasing the phototropic effect in phototropic glasses
IPC: C03C3/11
Filed: 1981-05-12
Abstract: The phototropic effect in a silver halide-containing phototropic glass is increased by producing metallic (e.g. Ag, Au, Hg, Cd or a mixture thereof) seeds or nuclei on the surface of silver halide-containing, crystalline or non- crystalline precipitates in the glass, whereby the transmission change from the colourless, unexposed phototropic state to the absorbing, exposed phototropic state is facilitated. These seeds or nuclei may be formed by reduction of the glass to effect self-seeding and/or by foreign seeding by addition of metal to the glass charge.

Title: Producing glass fibre reinforcing web
Inventor: GILDER ROGER JOHN
IPC: D04H3/11
Filed: 1981-08-20
Abstract: A reinforcing medium comprises a web, tissue or mat formed of continuous glass filament yarns entangled with glass fibre monofilaments. Threads of molten glass 1 fall on to a rotating drum 2 and solidify, the monofilaments so formed break away from the drum 2 assisted by a scraper 3 and are entrained in an air stream to be carried through a hood 5 on to a conveyor 7. The air stream may be formed by the rotation of the drum 2 within a shroud 4. Fed into the air stream from creels 8 are continuous glass filament yarns 9 to be carried through the hood 5 for deposition on the conveyor 7. During their progression the yarns 9 become entangled with the monofilaments, particularly within the hood 5, so that the deposited fibres are an entangled tissue on the conveyor. The tissue on the conveyor is coated with a resin bonding agent and cured to provide a substantially stable mat suitable for the reinforcement of plastics mouldings. <IMAGE>

Title: Process for producing an egg product
IPC: A23L15/00
Filed: 1981-09-07
Abstract: A chopped egg product is prepared by:   (a) separately heating egg yolks and egg whites at a temperature of from 165 DEG F to 210 DEG F (73.89 DEG C to 98.89 DEG C) to coagulate the yolks and whites;   (b) freezing the coagulated yolks and whites; and (c) chopping the frozen yolks and whites at a temperature of from 22 DEG F to 30 DEG F (-5.56 DEG C to -1.11 DEG C) to provide a chopped egg mixture.   This product may subsequently be refrozen and then thawed, as desired, for use. Optionally, the heating step is carried out in two stages, in the first of which the yolks and whites are separately dynamically preheated to a temperature not exceeding 183 DEG F (83.89 DEG C) for the egg yolks and to a temperature not exceeding 167 DEG F (75 DEG C) for egg whites, and in the second of which they are statically heated to a temperature within the aforementioned range of from 165 DEG F to 210 DEG F (73.89 DEG C to 98.89 DEG C). A water binding agent, e.g. starch, flour, alginate, carrageenan or xanthan gum, may be included to prevent syneresis, and a proteloytic enzyme may be added to the yolk portion.

Patent GB-2111236-A (GB)
Title: Lens system having bullseye filter
Inventor: KING RUSSELL
IPC: G02B5/00
Filed: 1981-12-04
Abstract: It is common practice for a pilot's Head Up Display (HUD) to be recorded, nowadays with a CCD video camera. Unfortunately, the spectral response of available CCD cameras- high at the red end of the spectrum- coupled with the fact that conventional HUDs employ a cathode ray tube having a high intensity "green" phosphor coating, causes problems. Placing in front of the camera a full field spectral filter of the green pass/red cut variety is an acceptable solution when ambient light levels are high, but not when they are low, for it causes the camera's low light sensitivity to be very much reduced. The present invention seeks to overcome the problem for lens (11, 12, 13) systems of the type having an iris diaphragm (14) by using not a filter covering the entire available aperture of the system but rather a "bullseye" or "spot" filter (15) of relatively small diameter so that when placed athwart the optic axis it is effective for only a small, centrally- located, portion of the system's full aperture. <IMAGE>

IPC: F16K31/40
Filed: 1982-12-02
Abstract: An electro-magnetic valve for controlling the flow of compressed air to a utilisation device in a vehicle system, comprises a pneumatic actuator B through which a main flow path extends and an electromagnetic actuator A that is energisable to actuate the pneumatic actuator. The electromagnetic actuator has a movable core (14) that directly actuates a first pneumatic, change-over, switching valve that connects the pneumatic actuator A with ambient at (35) in the rest condition or with a pressure inlet port (30) in the energised condition. The pneumatic actuator B is a spring biased piston (22) which is displaced upon actuation of the first switching valve.

Title: Regenerative air conditioning unit
Inventor: HRYNISZAK WALDEMAR
IPC: F24F12/00
Filed: 1984-07-06
Abstract: A heating and ventilating unit consists of a regenerative heat exchanger whereby its heat exchanger part, i.e. the matrix being contained in a rotating disc 1, is preferably made from a ceramic engineering material. This matrix is sub-divided into at least two circular sectors 2,3 each of which fulfils a different heat exchanging function. Furthermore, a combustion chamber 4, two blowers 5,6, one for the fresh air the other for the stale air as well as means for driving the disc and controlling the performance of the unit are included. A cooling capability is achieved by expanding the stale air in an expander (turbine) 10 thus reducing its temperature before passing through the matrix of the heat exchanger and raising the pressure of this stale air after leaving the matrix in a compressor before being expelled to the atmosphere. <IMAGE>
