Title: Improvements in or relating to a window cleaner
IPC: A47L1/02
Filed: 1949-11-15
Abstract: 664,132. Window cleaners. TRICO PRODUCTS CORPORATION. Nov. 15, 1949 [Dec. 2, 1948], No. 29254/49. Class 138 (i) [Also in Group XXVIII] A cleaner for a slidably adjustable window 3 of a motor vehicle comprises a wiper 4 rockably mounted adjacent the window and means whereby the wiper is automatically urged against the surface of the window when the window is moved to and/or from a closed position. The wiping blade 4 is mounted in a channelled holder 5 in the window receiving well 2 of a vehicle door 1 so that as the window 3 is raised and/or lowered into the well 2 it is cleaned by the blade 4. The window is moved by means of a piston 14 connected to the window by cable flights 16. The piston 14 is moved one way or the other by the opposite ends of its cylinder 13 being connected to the induction-manifold 20 of the vehicle engine and to atmosphere alternately through two solenoid operated valves 18 controlled by push buttons 32. The blade holder 5 is rockably supported by trunnions 6 on the door frame and may be moved away from the window in one direction of its movement by means of a connection to an auxiliary spring loaded piston in a cylinder 21, which is connected to one end of the main cylinder 13. In an alternative construction the bladeholder shaft carries a rubber-tyred wheel which bears on the window surface and rotates the blade to or from the window as it is moved. Movement of the blade is limited by stops. A channel to remove moisture collected by the blade is provided on the blade-holder or on the window frame; this channel leads to a conduit 12.

The invention relates to a gas turbine engine of the kind having a rotary regenerative heat exchanger, the axis of rotation of the heat exchanger being disposed at an angle greater than 0‹ and less than 90‹ to the axis of the engine. The engine shown in Fig.1 comprises compressor 1, combustion chamber 9, compressor-drive turbine 3 and separate power turbine 4. The engine comprises also a rotary regenerative heat exchanger 10 the rotational axis 11 of which is inclined at angle # to the axis 12 of the engine. The combustion chamber 9 is located within the heat exchanger, the axis 9a of the chamber being parallel to the axis of the heat exchanger. The turbine exhaust gases pass to space 14 and then radially through the drum, finally discharging through an exhaust outlet. Air from the compressor passes to space 26 then radially inwardly through the drum being pre-heated thereby and then passing to the combustion chamber.

Title: Digital code translating system
IPC: G06F3/06
Filed: 1957-09-25
Abstract: 828,747. Optical recording and reproducing apparatus. ATELIERS DE CONSTRUCTION BEAUDOUIN. Sept. 25, 1957 [March 18, 1957], No. 30073/57. Class 40 (2). [Also in Group XIX] In a system for reading a digital code record of the type wherein code words are recorded in longitudinally displaced relation along a longitudinally displaceable medium, each word consisting of a number of code elements recorded transversely across the medium, scanning means are provided for serially scanning each word and producing a corresponding electric output from the elements scanned thereby, and means for controlling the electric output to emit an output pulse only while the scanner is at the mid-point of the corresponding code element. In the embodiment described, Fig. 1, an optical system is used employing a multi-track film 1, containing words each of which comprise a number of transverse elements distributed over eight separate tracks 13, as shown in Fig. 2. The film is fed over a supporting platen 3 having a slit 4 therein. A scanner unit 5 is mounted for transverse reciprocatory displacement and carries a light source 6, optical system 7 and photo-electric cell 8. An optical grating 9 is mounted on the unit 5 and is bodily displaceable with regard to a stationary light source 10, optical system 11 and photoelectric cell 12. Each elementary code position represents a binary digit 0 or 1, and the cells 8, 12 produce a voltage or not according to whether a transparent portion or not is being scanned. A track 14 contains start-of-word code elements, and track 15 contains end-of-word elements. The spacing between lines on grating 9 equals the width of a start element 14 and corresponds to one-third of the track spacing on the main record. The reciprocating movement of unit 5 is related to the longitudinal movement of the film by means not shown. The output pulses from photo-electric cell 12 are applied to an electronic switch gate 20 connected to a three-stage counter 23 which emits an output pulse at every third input pulse to control a nine-stage stepping register 24, the outputs of which are applied as first inputs to nine coincidence circuits. Each of these have second inputs in parallel connected to photo-cell 8, and when output pulses therefrom are emitted both inputs are energized, and as this occurs on every third pulse of the photo-cell 12, the pulses emitted from the coincidence circuits can be timed to correspond substantially with the midpoints of the successive bits of each word on the main record. The outputs are connected to a multi-position switch 26, from each position of which extends a separate line for connection to a suitable output unit such as a card punching machine or computer memory.
