Title: Improvements relating to centrifugal fans
Inventor: BAVERSTOCK PETER
IPC: F04D29/66
Filed: 1960-11-08
Abstract: 926,088. Measuring electrically. CARL SCHENCK MASCHINENFABRIK G.m.b.H. April 5, 1961 [May 21, 1960], No. 12244/61. Class 40 (1). In a load cell in which the sensitive elements are sealed inside a casing and the member to which the load is applied is sealed to the casing by, e.g., a diaphragm, the load-receiving member is sealed to the casing at a second point so that any load on the sensitive elements due to difference in pressure between the inside and the outside of the casing acting on the first sealing means is compensated by an equal but opposite force generated in the second sealing means. Fig. 1 shows a cell in which the deflections of a bar 1, due to a load applied to a member 4, are detected by strain gauges 2. The member 4 being sealed to the casing 3 and 5 by diaphragms 6 and 7, changes in differential pressure across these diaphragms imposing a stress on the member 4 but not stressing the bar 1. An alternative embodiment is shown in Fig. 2 in which the sensitive element, i.e. bar 11 having strain gauges 12 attached thereto has an annular sleeve 16 attached to its end 15, the sleeve being sealed to the casing by diaphragms 17 and 18 and to the sensitive element by diaphragm 19.

Inventor: WIGGINS HARRY ANTHONY RICHARD
IPC: H04N5/073
Filed: 1965-09-10
Abstract: 1,093,788. Television. RANK ORGANISATION Ltd. Aug. 12, 1966 [Sept. 10, 1965], No. 38797/65. Heading H4F. In a multi-camera television system, e.g. a closed circuit television system, synchronization between the cameras is obtained by feeding the line and field synchronizing pulses from the line and field drive circuits in one of the cameras (the master camera) to the synchronizing oscillators of the other cameras (slave cameras) via respective synchronizing feed lines and resistive splitters. The system is essentially a random interlace system and for accurate phasing the signal delay in each synchronizing feed circuit is arranged to be identical. The Specification states that if suitable circuits are chosen for the synchronizing oscillators in the cameras, it can be arranged for the multi-camera system to operate in a non-locked condition if the master oscillators or the synchronizing feed lines from the camera providing the master oscillators fails.

Filed: 1963-10-03
Abstract: 1,039,178. Ships' derricks. A. E. HALLEN. Oct. 3, 1963 [Nov. 9, 1962], No. 39047/63. Heading B8B. Arms 5, 6, Fig. 2, which carry topping-lift guide-pulleys are universally pivoted to an athwartships beam 4 of a ship's derrick and restrained in their pivotal movements by cables 8, 9 and 10, 11 respectively. The lengths of the arms and cables are such that the boom can always be swung back from a position over the side i.e. the arms do not swing further inwards than the position of arm 5 in Fig. 2. The topping lifts 13, 14 are wound on winches 15, 16, Fig. 1 (not shown), and a load fall 29 is wound on a winch 32. Alternatively, the topping lifts may pass from one winch to the other and be wound in the same way on one and opposite ways on the other so that one winch luffs and the other slews the boom. Fig. 5 shows an arrangement with a shorter athwartships beam in which arms 5, 6 are supported by two cables and two rigid arms 43, 44. These latter arms are attached to arms 5, 6 by sliders 45 to permit limited movement as before. The arms 43, 44 may be telescopic. Fig. 6 shows an arrangement for heavy loads in which each topping lift comprises two parts, e.g. three runs 14<SP>1</SP> between the boom head 12 and the arm 5, one of these passing to a winch, and two runs 14<SP>11</SP> between the boom head and the midpoint of a beam 4. During slewing the length of the parts 14<SP>1</SP> only is changed. For use with lighter loads operation can be speeded up by detaching the parts 13<SP>11</SP> (not shown) and 14<SP>11</SP> from the beam 4 and attaching them to the base of the boom. The swinging arms may be used with dual masts or attached directly to the ship's superstructure.
