Patent GB-801223-A (GB)
Abstract: 801,223. Recording-apparatus. ASKANIAWERKE A.G. April 29, 1955 [April 30, 1954], No. 12495/55. Class 106 (4). [Also in Group XX] A recording theodolite makes a record of the sighting mark and of the angular readings thereof and comprises angle indicating members and transmission means associated therewith which produce on a record strip separate indicia which by their magnitude position or intensity represent the separate digits of the recorded angle. The recorded indicia are intended to be scanned automatically by photoelectric, magnetic or electrical devices. Thus the indicating members may carry magnetized markings recorded magnetically or the movement of the indicating members may generate electrical pulses which are counted, the digits of the sum being recorded. Alternatively, the indicating members may carry marks, the indications of which are transmitted optically and recorded photographically or magnetically. Thus in the form shown the disc 1, of which the angular position is to be recorded, carries a spiral 6 embracing three quadrants, identical spirals 5 in each of the four quadrants and " tens " and " units " graduations 3, 2. The position of the portion of the spiral 6, as observed through a window 7 is recorded as a mark at a distance a from a datum line 12 on a film frame 11. The spiral 5 as observed through a window 8 is similarly recorded as a mark at a distance 6. The positions of tens and units graduations appearing in windows 9, 10 are recorded as marks at distances c, d. In a modification, each spiral is replaced by a group of concentric circular arcs of different lengths, the number of which appearing in the window is recorded.

Title: Pneumomechanical Braking Cylinder
IPC: B60T17/08
Filed: 1980-11-05
Abstract: In a pneumomechanical braking cylinder braking is releasable by disconnection of the hollow stem of a mechanical actuator from a related plunger or piston upon manual operation of a control rod. The release mechanism is provided by means of balls (20) housed in radial holes (19) presented by the hollow stem (9) of the mechanical actuator (B) of the cylinder, which balls engage either with a bush or sleeve (21) externally of the stem, integral with the actuator plunger or piston (6), or with an inner bush or sleeve (10) mounted on a control rod (11) operated by the operator. The release of the mechanical braking occurs by a slight rotation of the control rod against the action of a return spring (12). During this operation, said inner bush or sleeve is moved to such an angular position as to accommodate said balls (20), thus allowing the release of the stem from the outer bush or sleeve and hence from the plunger or piston. <IMAGE>

Title: Improvements in or relating to control apparatus
Inventor: SOMERVILLE MICHAEL JOHN
IPC: F23N5/00
Filed: 1982-12-08
Abstract: This invention relates to control apparatus, and a basic system according to the invention is illustrated in Figure 1. This Figure shows a system (1) having means (2 and 3) for adjusting operating variables X and Y. A measuring device (5) measures a characteristic (2) resulting after a time delay. A generator (6) produces an output Z' representing a desired value of Z. This generator is controlled in dependence on the value of X. The measured value of Z is compared with Z' in a comparator (7) to produce an error signal E. A storage system (8) stores control signals each representing a value of Y associated with a respective value of X. These control signals are continuously updated by means of the error signal E in the direction necessary to reduce the value of E towards zero. Once the control signals have been built up in all the storage locations, the control apparatus will respond substantially instantaneously to provide a value of Y which is very close to the value required at any value of X to maintain the actual value of Z close to Z'. The invention is particularly applicable to combustion control apparatus for burners, and one example of combustion control apparatus in accordance with the invention is shown in Figure 4. This Figure shows a burner (12) having a motor-controlled fuel valve (15), and a motor-controlled damper (16). Coarse control of the damper position is provided by a mechanical profiler (18). A system basically similar to that shown in Figure 1 is used to control a trim motor (19) which provides fine control of the damper (16). <IMAGE>
