Title: Improvements in or relating to reflectors for use in the production of artificial daylight
IPC: F21V9/02
Filed: 1920-08-12
Abstract: 170,707. Turing, H. D., and Shering- ham Daylight, Ltd. Aug. 12, 1920. Reflectors.-A reflector coloured with two or more separate colours for modifying the light from an artificial source so as to resemble daylight, as described in Specification 139,287, is constructed of a number of superposed layers or partial layers of material, each layer or partial layer being coloured with one of the several colours to be used and so superposed as to expose parts of the lower layer. In one form of the reflector, employing three or four colours, the inner surface of a conical or other shade 1 is covered with a uniform layer 2 of material coloured with one of the colours. Over this first layer is placed a second laver 3 of material coloured with another of the colours and perforated uniformly with circular or other holes 4. Upon this second layer are placed radial strips 5 coloured with the third colour, the three layers being secured to the shade 1 by means of bolts 6 passed through the radial strips, the heads or nuts 7 of the bolts being coloured with any of the colours previously used or with a fourth colour if desired. Preferably the reflector is made fireproof, the first layer being of asbestos whilst the other layers may be of zinc or other metal.

IPC: B66C13/00
Filed: 1920-08-17
Abstract: 170,715. Marks, E. C. R., (Pohlig Akt.- Ges., J.). Aug. 17, 1920.

Abstract: 1,003,604. Hydrostatic transmissions; valves. C. VAN DER LELY N.V. June 21, 1962 [July 18, 1961], No. 24000/62. Headings F2C and F2V. A valve, particularly for use as a relief valve in an hydrostatic vehicle-transmission of the type described in Specification 1,003,605, comprises an axial chamber communicating with a series of channels 11, 12, 13 and housing a series of plungers 19, 20, 21 which are normally biased by a spring 24 against a stop 32 where the end of the lower plunger 19 forms a wall portion for a compartment 6 communicating with channel 11 by ports 14, and similarly for the second plunger 20, channel 12 and ports 15, the arrangement being such that in this normal position the plungers seal the channels 11, 12 from each other, but in the event of the pressure difference in the channels overcoming the loading of spring 24 the plungers are raised to open communication between the channels through ports 14, 15. As shown the channels 11, 12 are connected to passages 33, 34 in communication with the high and low pressure circuits respectively of the hydrostatic transmission. The valve housing also incorporates a check valve of generally similar construction, with three plungers 38, 39, 40 and a loading piston 41, the valve having connections 54, 56 with the transmission system and being connected to the relief valve of ports 50, 51, 52.

Title: Improvements in or relating to pumping installations
IPC: F03B13/26
Filed: 1919-10-01
Abstract: 156,315. Banister, F. M. Oct. 1, 1919. Buoyancy motors; siphons; tidal energy, utilizing.-A float B rises and falls in a caisson &c. A and actuates a pump piston D. Water is supplied from the sea &c. to the caisson by a pipe H, the mouth of which is provided with a valve M actuated by a float P and is protected by a grating R. The caisson is emptied through a siphon pipe J provided with a valve Q which may be actuated by a float. In the case when the liquid level varies between K and L, the upper end of the caisson is closed. When the water in the caisson is at the level shown, the float P closes the valve M. Water is now admitted to the pipe J by the pipe S to displace any air in the siphon and the valve Q opened to allow the siphon to empty the caisson. When the caisson is empty the float P opens the valve M and the caisson is filled again.

Title: Arrangement for maintaining the speed of rotation of motors constant, or of synchronising them
IPC: H02P5/52
Filed: 1929-08-06
Abstract: 316,953. Siemens & Halske Akt.- Ges. Aug. 6, 1928, [Convention date]. Constant-speed control systems.-The motor M has a field resistance RZ intermittently shortcircuited by a vibratory relay contact 3 in parallel with a short rotary contact a and in series with a long rotary contact b. The vibratory contact is operated by an electromagnet energized by an alternating current of constant frequency, or of frequency depending upon the speed of a controlling apparatus with which the motor is required to synchronize. Both the rotary contacts are driven by the motor M, and are disposed so that increase of speed prolongs the period of short-circuiting and decrease of speed shortens it, the effect being to change the average value of the motor field strength in a compensatory direction. The invention may be used in connection with picture telegraphy and high-speed telegraphy.

Patent GB-1307778-A (GB)
Title: Digitally pulsed dielectirc line scan recorder
IPC: G03G15/32
Filed: 1971-04-19
Abstract: 1307778 Facsimile recorder EG & G Inc 19 April 1971 [11 March 1970] 24068/71 Heading H4F In a facsimile recorder three styli 36 mounted at approximately equal intervals on a driven belt loop 24 sequentially traverse successive lines in contact with the dielectric surface of a recording web 12 which has a conductive base and is stepped a line at a time by a metal roll 20 at earth potential, and brushes (104) connected to each stylus run along a metal strip (112) on an insulating bar 110 so that a facsimile signal fed to the strip causes the operative stylus to lay down a corresponding electrostatic pattern on the web 12. As described the facsimile signal consists of 1800 bits/line and clock pulses at that rate are also derived from the belt drive motor 38. The receiver stores the incoming signal, and when a complete line is available, provides a "line ready" pulse which sets a bi-stable. An AND gate receives the output of the bi-stable and the output of a light source-light fibrephoto-cell combination which detects when an oncoming stylus passes a predetermined position adjacent one edge of the web 12, and the resulting pulse, after being delayed to allow the stylus to cross the margin of the web, resets the bi-stable and enables the stored line to be clocked out of the receiver to the metal strip (112). Such an arrangement avoids the need for accurate spacing of the styli on the belt loop, and variations in the belt speed do not affect reproduction. A cam arrangement lifts each stylus as it crosses the edge of the web 12, Fig. 4 (not shown). The end of the web 12 is held by rolls 53 and 54 and forms a festoon 51 while an image is being recorded. An "end of picture'' signal causes a shearing blade 50 to be rotated through a small angle to cut the web on a blade 52, and the rolls 53 and 54 rapidly feed the festoon through a toner unit 60 and thence to a heated roll 154 to fix the image. When a photo-cell 58 senses the trailing edge of the festoon, a bar 70 is pivoted to position 74 to guide the next leading edge of web 12 between rolls 53 and 54 at a slow rate determined by the speed of roll 20 (rolls 53 and 54 are provided with a slip clutch). The cell 58 then detects the leading edge and stops the rolls 53 and 54 to form another festoon. The toner unit described uses a magnetic brush roller 152 and a mixture of toner and iron filings. The roller is formed of corrugated, alternately magnetic and non- magnetic washers and the toner-filing mixture is picked up thereby. Only the toner is held by the web 12 and is continuously replaced during recording.

Patent GB-242401-A (GB)
Abstract: 242,401. Baker (Leicester), Ltd., W., and Baker, W. Sept. 30, 1924. Stop-motions.-The yarns in passing across the forked ends of fixed guides 5 hold up droppers 1 each fixed to plates 2 pivoted at 3 and normally held out of contact with studs 14. When contact is made an electrical circuit is established. The elements 2, 3, 14 are enclosed in a box mounted above the bobbin stand. Leads 15, 15a, 44 and 45 electrically connect the pivots and studs 3, 14 to trip &c. devices in a casing 18 mounted above the machine bed. An electromagnetic device 23 of known form is thus energized and the hammer 37 depresses a trip arm 34. A catch 22 is then released and in its turn releases a spring plunger 21. The movement of the catch is limited by a shoulder 48. As the plunger 21 moves it breaks the circuit by lifting a contact 38 away from a terminal 42. The plunger is connected to the clutch or other driving gear by means such as a hooked wire, a flexible connection and toggle links. The plunger may be released by an intermediate relay device with a weaker spring and may actuate a needle detector of known form. The plunger may be operated from the droppers by mechanical means.
