Patent GB-2095950-A (GB)
Title: Surveillance
IPC: G01C11/02
Filed: 1982-04-01
Abstract: In surveillance of the ground from an aircraft 3, an optical radiation sensitive line scanner, e.g. an I.R. scanner, is pivotably mounted in the aircraft and is so repetitively rocked in its mounting that each portion of the ground is scanned twice from different viewpoints, the resultant scanning signals can be used to obtain a stereoscopic display for example. Instead of rocking the scanner, just the look-direction defining optical system thereof can be moved or, particularly where the aircraft is a "drone", i.e. a remotely piloted vehicle (RPV) the entire craft can be rocked, i.e. flown along a kind of see- saw path (see Figure 7, not shown) or along a straight path but with its pitch changing repetitively. <IMAGE>

Title: A method of and device for retracting the loops and ends of hand towels to a cloth hand towel dispenser
Inventor: ARABIAN SANDRO
IPC: A47K10/28
Filed: 1984-06-04
Abstract: In known textile towel dispensers the clean towel is manually pulled out at the front, the used towel is automatically drawn in at the rear, and the end of the towel hangs down vertically when the roll of clean toweling has been used up. The inventive towel retracting or retraction apparatus contains a towel loop loaded with a weighted roller and concealed by a cover which can be part of an enclosure. The used toweling or towel section is thereby pulled behind the cover where it can neither be seen nor reached by the user. A delay mechanism ensures that the towel loop, which is partially pulled out from the towel dispenser and partially pulled out from behind the cover, remains stationary for a few seconds before it is retracted behind the cover.

Patent GB-2164300-A (GB)
Title: Bicycle frame and bicycle
Inventor: KIRK FRANCIS GEORGE
IPC: B62K19/12
Filed: 1984-09-14
Abstract: A cross bar 1, a lower bar 2, a bridge 31, a saddle stem 3, and rear forks 11 and 12 are cast in one piece from a magnesium-based alloy. An important feature of the frame is the additional stiffening of the frame against torsion by means of the structural bridge 31. The bridge is cast solid with the cross bar 1 and lower bar 2 and acts as a torsion arm so that any twisting of the frame due to deflection of the head 4 out of the plane of the frame is not resisted by the ends of the cross bar 1 and lower bar 2 remote from the saddle stem 3, but at locations considerably nearer the saddle stem 3. A further improvement is achieved by shifting the junction of the bottom bar 2 upwardly from the lower end of the saddle stem 3 as illustrated in Figure 1. By this means, the overall length of the bottom bar is reduced, thereby further reducing the length of the beam it forms, and also saving material and therefore weight. In addition, there is some reinforcement of the saddle stem 3 itself. <IMAGE>
Patent GB-846243-A (GB)
Abstract: 846,243. Variable-speed gear. GENERAL MOTORS CORPORATION. Sept. 18, 1958 [Oct. 7, 1957], No. 29904/58. Class 80 (2). A motor - vehicle variable - speed gear comprises a hydrodynamic torque transmitter having an input impeller 20 and two runners 22, 24 which latter exchange turbine-reactor functions for forward and reverse drive, together with a planet train comprising an output-mounted ring- gear 34, a planet-carrier 28 permanently connected to one runner 22 and carrying intermeshed short and long planets 32, 30 meshing respectively the ring 34 and two equal suns 38, 40, which, when rotating, always rotate at the same speed. For forward, one-way drive, application of a cone brake 60 prevents reverse rotation of the runner 24 and sun 40 through one-way detents 100, 46, respectively. In a first phase the runner 24 acts as a reactor, and the runner 22 as a turbine driving the planet-carrier 38, which, reacting on the sun 40, provides mechanical gear reduction. With speed increase, the runner 24 begins to rotate forwards, eventually reaching a coupling-phase, the gear train still reducing. A third phase (still one-way) is provided by engaging a clutch 44 for direct mechanical drive of the. sun 38, giving overall split-torque drive at near one-to-one, the sun 40 over-running its detent 46. A two-way reduced forward drive is provided by releasing the clutch 44 and bridging the sun detent 46 by a cone clutch 86 to give two-way reaction on the brake 60 for permanent geared reduction. For reverse the clutch 86 is engaged together with a cone brake 62 which latter holds the planet-carrier 28 and runner 22. The latter acts as a reactor to reverse the runner 24, which drives the sun 40 reversely through the detent 100 and clutch 86, the gear train providing further reduction. Input- and output-driven pumps 118, 120 provide pressure for the clutches and brakes.

Title: Multi-function data signal processing method and apparatus
Inventor: THOMSON DAVID JAMES
IPC: G11B20/14
Filed: 1984-05-10
Abstract: A data signal is processed to change its form and spectral content without introducing undesirable frequency and amplitude effects. Multiple data signal states, which determine the essential characteristics of the output signal wave configuration, are utilized in conjunction with clock signals at a rate substantially in excess of twice the largest frequency component of the data signal in order to construct the desired output signal wave configuration. In one embodiment, an input data signal (23, 26) is in an NRZ format and is processed for conversion to the biphase, or Manchester, format by a ROM table (10) look-up function addressed jointly by the input signal states and the clock (11) signals.

Title: Fastening means
Inventor: CHERITON ANTHONY
IPC: E05C3/14

Abstract: Fastening means for a closure member, for example a casement window, (13) comprises a carrier (10) to which is pivotally mounted a latch member (19) having an abutment surface (28) for engagement with a keeper (30). The arrangement of the fastening means with a latch axis (18) parallel to the surface of a closure member to which it is secured enables the design of a fastening means which engages a keeper to maintain the closure member in a closed position without the application of undue force thereby minimising distortion and damage to the fastening means and to the closure member itself. <IMAGE>

Title: A method of and apparatus for recording an image
Inventor: SAKAMOTO TAKASHI
IPC: H04N1/48
Filed: 1985-02-26
Abstract: A single light beam scans unit reading regions of an original image, each covering a predetermined number (e.g. 2) of picture elements and each occupying a plurality (e.g. 2) of scanning lines, the single light beam being arranged to cover the said plurality of scanning lines. A pick-up lens (2) and a beam splitter (3) divide light from the original image into three light paths. Light on one path (111) passes via a lens (41) to a series of dichroic mirrors (5,6,7); reflected light passing via respective colour filters (18R,G,B) to photoelectric converter (8, 91,10) produces three colour signals (RO, GO, BO) from which four colour separation signals are derived for a representative picture element in a region of picture elements. Light on a second path (112) reflected from a dichroic mirror 62 is passed via a filter 18G to a photoelectric converter (92) to enable signals representing green brightness of each of the other picture elements of the region to be derived. Light on a third path, not shown, may fall on a photo-electric converter to provide an unsharp signal, used in detail enhancement. <IMAGE>
