Filed: 1972-06-02
Abstract: 1355152 Photographic processing S NEEDLEMAN 2 June 1972 [2 July 1971] 25920/72 Heading G2X Photographic sheet material is processed by supporting it above an inclined platen and flowing processing solution on to the platen so that a laminar downward flow is provided between the sheet material and the platen. An apparatus for effecting this processing comprises an oblong platen, means for supporting the platen so that it presents an inclined surface in use, a channel situated at the upper end of the inclined surface and having walls extended transverse to the platen, means for holding the sheet material over the platen in a position overlying the channel, a chamber for applying processing solution communicating with the channel, a pump for forcing processing into the chamber and from the chamber into the channel whereby a layer of processing solution flows from the channel over the platen, and flow modifying means in the path of the liquid from the chamber whereby the flow over the platen is substantially laminar. As shown, platen 17 is mounted on a frame having a rocker base 37 and containing liquid 36 which stabilizes the apparatus and may be heated and used for storing containers (50), 51 of processing liquid. One or two photographic sheets 58, (58b) are held over platen 17 by a bar 21, (21b) or taping to a clamp (67) or (67'). Processing solution is pumped from a trough 26 to chamber 40 and then out through channel 38 on to platen 17. Laminar flow is achieved by deflector plates 61, Venturi tubes 55 having flared ends (57) and optionally a porous material in channel 38 or between channel 38 and chamber 40. A choke bar 34 is provided which when depressed causes processing liquid to flow over both sides of sheet 58 on platen 17. A second liquid (e.g. wash water) may also be introduced into chamber 40 from an outside source via a valve (39). In a modification Fig. 11 (not shown) the platen is curved and not planar.

Title: Safety device for gas burners
IPC: F17D5/00
Filed: 1954-09-08
Abstract: 762,435. Lamp failure alarms. JUNEAU, A., and JUNEAU, E. Sept. 8, 1954, No. 26050/54. Class 118 (2). An electrical indicating system combined with one or more gas burners (not shown) comprises a gas pressure operated main switch 5, 6 controlling the supply of current to a first and a second signal circuit, the first signal circuit including a signal device such as a lamp 19 and being completed for a predetermined time at starting by a time switch 17, a series switch 15 closed by opening a gas burner supply valve 11  and a thermal switch 16 which is eventually opened by the heat of the gas burner, and the second signal circuit including a signal device such as a lamp 20 and being completed at starting and during running by a series switch 15 closed by opening a gas burner valve 11. There is one switch 15 and one thermal switch 16 associated with each burner. At starting of any one burner the movable arm 25 of the time switch 17 contacts the contact 27 to energize the lamp 19 and the switch 15 of that burner is closed by opening its gas valve 11. Afterapredetermined time the arm 25 breaks contact with the contact 27 and makes contact with a contact 26 connected to an alarm bell 18 which is therefore energized if the thermal switch 16 has not opened its contacts in consequence of the burner being ignited. The main switch 5, 6 is operated by a plunger 2 having two pistons 12, 12<SP>1</SP> slidable in a cylinder 1 having a gas inlet 7 and two lateral ports 8, 9 communicating with a pipe 10 leading to the burners. When the gas valves 11 of all the burners are closed the gas pressure in the pipe 10 holds the plunger in the position closing the inlet 7 but when a gas valve 11 is opened the pressure in the pipe 10 is reduced and the plunger moves to the right against the action of a spring 4 to connect the gas inlet 7 with port 8 and to close the main switch 5, 6. The alarm bell 18 may also be energized through the main switch 5, 6 and through contacts 21, 22 which are closed when all the burners are out of use, the main switch 5, 6 in this case closing if a gas leak occurs in the pipe 10. The contacts 21, 22 are opened by an electromagnet 14 when a gas valve 11 is opened.

Title: Optical beam splitting or combining systems
IPC: G02B5/28
Filed: 1951-11-13
Abstract: 716,332. Optical systems. TECHNICOLOR MOTION PICTURE CORPORATION. Nov. 13, 1951 [July 21, 1951], No. 26548/51. Class 97(1) An optical image-forming system is combined with a transparent body carrying a wedge-shaped interference coating disposed at a predetermined distance from the exit pupil of the system. The thickness gradient of the coating is so related to this distance from the exit pupil that for chief rays the shift of the reflection and transmission bands in one sense due to change in angle of incidence across the coating is substantially equal to the shift of such bands in the opposite sense due to change in thickness of the coating, whereby there is substantially no variation across the coating of the peak reflected and transmitted wavelengths. The transparent body may be an optical flat or cube 'and there may be more than one interference coating. In one form, Fig. 9, the optical system comprises a lens 04 and the transparent body is composed of four prisms P5 to P8 supporting crossed wedge-shaped interference coatings, the thickness gradients of which are related to the distance of the coatings from the exit pupil of the system. The coatings transmit green light while one coating Cw3 reflects blue light and coating Cw4 reflects red light. In another form, Fig. 11, light from three cathode ray tubes 41, 42. 43 passes through a Schmidt system and is combined by crossed coatings Cw8, Cw9 on a screen 51. In Fig. 10, light from a cathode ray tube 21 is modulated by a colour film 25 and split by coatings Cw6 and Cw7 so that blue, green and red light falls on phototubes 30b, 30g and 30r respectively. The wedgeshaped coatings are obtained by vaporization on a surface tilted at the required angle which is determined from known calibration data. The optical principles underlying the invention are fully explained in the Specification and Specifications 398,339, 666,160 and 711,814 are referred to.
