Title: Improvements in or relating to regulating the rolling of malleable or plastic materials into sheets or strips
IPC: B21B37/18
Filed: 1954-12-28
Abstract: 794,506. Roller machines for sheeting plastic materials. SANDVIKENS JERNVERKS AKTIEBOLAG. Dec. 28, 1954 [Dec. 28, 1953], No. 37489/54. Class 87(2). [Also in Group XXII] In a method of rolling sheet or strip the roll pressure or the tension in the work is controlled to maintain a constant thickness of product, the control signal being obtained from a measurement of thickness after the work leaves the rolls combined with a signal derived from a measurement of the rate of any change of thickness before the work enters rolls. In one application the motor 16, Fig. 1, driving the screw-downs 15 is controlled indirectly from pneumatic valve devices 11, 12 such as are described in Specification 627,204 [Groups XIX and XXIX] and which have diaphragms 19, 25, Fig. 2, normally taking up positions between chambers 20, 26 as determined by pilot valves which are adjusted by feeler rods measuring the thickness of the work. For measuring the rate of change of thickness at entry the chambers 20 on each side of the diaphragm 19 are interconnected through closed tanks 23, 24 and an adjustable throttling valve 21. The signals are combined mechanically by interconnecting the diaphragms through levers 27, 28 carrying an electrical contact 29 which is movable between adjustable contacts 30, 31. A reversing motor 32 supplied from a source 34 and controlled from the contacts may act as the screw-down motor 16 or may be used to vary the strip tension. Over regulation is prevented by inserting a vibrating contact 33 or a rotary current chopper into the circuit to obtain intermittent regulation. In a modification the screw-downs may be replaced by hydraulic rams, or a pressure chamber as described in Specification 665,437 [Group XXII]. Alternatively the signal may control a braking stress of a pair of rollers through which the strip is led to vary the tension.

Title: Portable camera equipment
IPC: G03B17/56
Filed: 1975-09-16
Abstract: 1528032 Portable camera equipment G W BROWN 16 Sept 1975 [16 Sept 1974] 38107/75 Heading G2A A camera has means which enables its weight to be supported from the body of an operator, and which also has a remote viewfinding device extending from the camera to transmit an image to the eyepiece for viewing. As shown, the camera is supported from a handle 18 which can be held by the operator. The magazine 48 is situated rearwardly of the camera, and is connected thereto by a film guide 50. The upper end of the handle terminates in a socket and gimbal arrangement 38, 40 in which is mounted a strut 42. This carries a platform 46 on which the camera 12 rests, so that it is cantilevered forward of strut 42. The lower end of the handle is attached to the upper corner of a triangular frame 24, a battery 26 and motor 30 being attached to the lower two corners of the frame. Thus the camera, magazine, battery, and motor are mounted in generally rectangular configuration, and in the same vertical plane, so that the centre of inertia of these components lies approximately at the handle. This helps to keep the camera in a steady position independent of the movement of the operator. The gimbal system is connected by a yoke 120 to a support arm 58, which is joined to another support arm 56 by a block 60. The other end of arm 56 is attached to a bracket 86 attached in turn to a brace or carrying strap 132 which is shaped to rest on the shoulder of the operator, thus supporting the camera and other components. A belt 134 enables the brace to be more comfortably worn. Preloaded balancing springs such as 80, 104, 110 extend diagonally across arms 56, 58. The combination of the harness mounting, the spring-loaded support arms, and the gimbal mounting, has the effect of "floating" the camera so that its orientation is not dependent on changes in position or movement of the operator. Further, since most of the weight is taken by his body, his hands are left free. A remote viewfinding system 14 comprises a flexible fibre optic bundle 144, which is attached at one end to the camera viewer 146. The other end is attached to a prism 154 and viewed through eye-piece 148. These are carried by a brace 152 supported on the head of the operator, in such a manner that the eye-piece 148 is positioned conveniently to his eye. A level-  indicating device, showing also angular deviation, is provided at the camera end of the fibre optic bundle 144, so as to be visible in the view-finder. The flexible nature of this fibre optic device enables the operator to take shots from a variety of angles. The viewfinding arrangement may be replaced by a video monitor, secured by a strut to the frame 24, Fig. 7 (not shown).

Filed: 1960-11-07
Abstract: 919,740. Coating apparatus. ROWLAND, T., and MOLINS MACHINE CO. Ltd. Nov. 6, 1961 [Nov. 7, 1960], No. 38166/60. Class 140. Adhesive applying apparatus comprises an applying roller 2 arranged to engage the material 1 to be coated, a roller 3 running in adhesive-applying contact with the roller 2, an adhesive container 4 mounted above the rollers and having an outlet which is closed by the two rollers 2, 3, means for maintaining the rollers in a substantially fixed relative position and means for rotating the rollers so that their surfaces at the nip move outwards from the container whereby adhesive may only pass out from the container 4 at the nip of the rollers, and the applying roller becomes coated with adhesive which is thereupon transferred to the paper. The parts of the container 4 where the roller surfaces run inwards are spaced slightly from the roller surfaces so that any adhesive remaining on the rollers may pass back into the container. The roller 3 may be grooved or patterned and the rollers are forced into close contact so that the applying roller 2 only has adhesive on those areas corresponding to the desired pattern. Roller 3 is supported at each end by spindle 9 in a pair of rollers 10 mounted on the end of a bell-crank lever 11 pivoted at 12 and acted upon by a strong spring 13. The spring 13 is mounted by a toggle arrangement for ease of release. The rollers 2 and 3 are connected by gear-wheels having a large backlash so that they do not normally drive but are able to prevent slipping between the two rollers. Adhesive is supplied to container 4, via pipe 5 and valve 7, from a tank 6 which is open to atmosphere but has a lid preferably with a wet sponge to prevent skinning of the adhesive.

Abstract: 1,023,848. Rectifying. STANDARD TELEPHONES & CABLES Ltd. Sept. 25, 1964 [Oct. 1, 1963], No. 38622/63. Heading H2F. In a television EHT rectifier comprising series-connected stacks W1, W2, W3 ... of selenium rectifier elements, a capacitor C is connected, at the input end 3 of the rectifier, in shunt with a fraction of the total number of rectifier elements to ensure 'that the voltage distribution across the rectifier is substantially uniform. The value of this capacitor is greater than the stray and internal capacitances associated with the rectifier elements, which capacitances would otherwise cause most of the input voltage to be dropped across the first few elements at the input end of the rectifier. The rectifier is fed from a high voltage pulse transformer T1 connected to an EHT source such as the synchronization flyback circuit of a television receiver. Each rectifier stack comprises an assembly of selenium discs in an insulating tube provided with end terminals. The stacks and the capacitor C may be mounted in clips on a plastic panel screwed to the casing of the transformer T1 (Fig. 2, not shown).
