Abstract: 824,475. Hose reels. ARO EQUIPMENT CORPORATION. Oct. 31, 1957 [Aug. 12, 1957], No. 33996/57. Class 99(2). A base reel lock comprises a cam lobe 50 rotatable with a hose reel, a locking cam 40 for cooperation with the cam lobe, the locking cam being oscillatably mounted and means biasing the locking cam to rotate to a locked position relative to the cam lobe when the wheel rotates in a hose retracting direction and to lock free position when the lobe is out of registry therewith. As shown, with the parts in the position of Fig. 2, if the reel is rotated in the direction of the arrow b (i.e. the hose retraction direction) the cam will bind against the cam lobe 50 and prevent reeling up of the hose when it is desired to permit the hose to retract it is first pulled outwardly for unlocking and as the pull on the hose continues the trailing edge of the cam lobe 50 will pass beyond the cam surface 56 and permit the cam 40 to be rotated counterclockwise under the action of the spring 44. Thereupon the hose may be released and the cam lobe will engage the cam 40 and swing the cam counter-clockwise whereupon the hose may be entirely reeled in without any locking interference by the cam 80. A supply connection 32 is shown for supplying the material to be dispensed through the hose 26. The shaft 17 may include a swivel connection for conveying the material from the source of supply to the hose.

Title: Improvements relating to hoisting apparatus
IPC: B63B27/22
Filed: 1922-12-13
Abstract: 212,639. Haiste, J. H. Dec. 13, 1922. Overhead travellers and transporters.-Apparatus for unloading trawlers berthed end on at a crowded quay, suitable also for discharging ships overside, removing spoil from excavations, and for like purposes, comprises an inclined runway 1 adjustable on vertical and horizontal pivots 10, 12 above the loading point. The load 17 is hoisted and traversed by a rope 18 passing over a travelling pulley 15 and guide-pulleys 19, 21, 22. The configuration of the runway is such that the load moves along a path such as A, B, C, D, overrunning the hauling rope after reaching the point B and swinging downwards and forwards on to the quay beyond the end of the runway. The pulley 15' returns to the loading position by gravity. For hauling by means of a winch on the quay, the bracket 20 carrying the guide pulley 19 is reversed as at 20<a>. An alternative position for a winch on the vessel is shown at 23. The slope of the lower part of the runway may be such that the pulley 15 remains over the hatch until the load has been raised to the position 17a, or the pulley may be held in position by a catch. The runway is built up of five lengths of n -section lattice structure, with interlocking lugs and ears. In a modification suitable both for discharging and for loading the runway is inclined downwards from the centre to each end, the rope 18 passes round a pulley at the centre instead of the outer end of the runway, and the travelling pulley moves from the centre to the end by gravity. In this form, the travelling pulley may be attached to an endless chain which follows the contour of the runway and passes to a winding drum in order to ensure the passage of the pulley over the summit of the beam. The load may be supported from the carriage of the travelling pulley by catches which engage a grooved block on the rope 18 and are released automatically by a trip-plate fixed at a suitable position on the runway. A number of runways 1, Fig. 9, may be operated from a winding engine 51 and shafting 53 for driving any of a series of winding drums 54 through independent clutches.

Filed: 1968-07-17
Abstract: 1,243,375. Surgical implants. C. H. SPARKS. 17 July, 1968 [25 July, 1967], No. 34049/68. Heading A5R. [Also in Division F2] A tissue die to be used to provide grafting material comprising body tissue encapsulating a support or reinforcing member, comprises a pair of spaced apart wall members defining a cavity, at least one of the wall members being perforate, there being a graft support or reinforcing member disposed within the die cavity. As in Figure 1, the die is arranged to provide a tubular graft implant and comprises an outer perforated steel tube 10 and an inner imperforate steel member (12) between which is positioned a synthetic mesh or fabric (15) to provide a reinforcement in the graft. In use, the die is secured to the patients' rib cage using tie members 25 and tissue grows through the perforations 11 into the die and forms a tubular graft encapsulating the reinforcement (15). The die is then removed from the patient, and the tubular graft is separated from the die so that it may be re-implanted into the patient or used for a second patient. An alternative die, Figures 4, 5 (not shown), comprises curved perforate and imperforate sheets (31, 30) containing a reinforcement mesh or fabric (36) and is used to provide a curved graft suitable for implantation into the cranium. The die is formed with holes (37) for securing the die into the patient. A third die, Figure 6, provides a heart valve and comprises perforate and imperf orate tri-cuspid (or bi-cuspid) members 40, (42) secured together about reinforcement material (51) and provides a heart valve graft or tri-cuspid (ir bi-cuspid) form. The valve, when open, provides a passage centrally between the cusps whose edges assume a sinuous form; when closed, the edges (62) of the cusps straighten and the cusps abut each other as in Figure 12 (not shown). For promoting suitable tissue growth in the die, the die may be seeded before implantation with blood or with periosteal or epithelial cells. It is stated that a graft structure comprising a tube with a valve at each end may be provided.

Title: Improvements relating to direct current tachometer generators
Inventor: ANGUS ERNEST THOMAS
IPC: G01P3/44
Filed: 1959-10-09
Abstract: 913,170. Commutation in tachogenerators. FERRANTI Ltd. Oct. 6, 1960 [Oct. 9, 1959], No. 34213/59. Class 38 (2). A D.C. tachogenerator has a permanently magnetized rotor 2 and polyphase stator windings W1, W2. .. W6 which are earthed at one end while their other ends are taken through series resistor combinations R1A, R1B, R2A, B2B ... R6A, R6B to a common output terminal. PNP transistors T1 . . . T6 are connected between earth and the junctions of the A and B resistors, and are controlled via amplifier (not shown) by photo-electric cells P1 ... P6 so that all transistors except that connected to the line from the winding having the highest instantaneous negative potential are conducting and prevent voltages from their respective windings from reacting the output terminal. The photo-electric cells are energized by separate lamps (not shown), shining through a 300 degree arcuate slot in a disc 5 on the rotor shaft so that at any one time five of the cells are energized and their corresponding transistors are conductive. Diodes D (D1 only is shown) may be connected between earth and the junction of the A and B resistors so that they prevent the collector potentials of their associated transistors from going positive during the positive half-cycle of their windings output. Reverse rotation of the rotor shaft would give no output when using the circuit shown, but in a modification, Fig. 3 (not shown), having both PNP and NPN transistors, with oppositely poled diodes in their collector leads and connected between earth and the resistor junctions, reverse rotation of the rotor shaft will merely alter the polarity of the output voltage. The invention is not restricted to six winding stators, and the rotor need not have only two poles. The photo-electric cells and their light sources may be replaced by other energy transducers, such as inductive pick-off coils whose magnetic reluctance is varied by the rotation of a magnetic disc, which are again used to actuate the switching circuits.

Abstract: 1,096,107. Measuring resistance. SMITHS INDUSTRIES, Ltd. Aug. 12, 1966 [Aug. 13, 1965], No. 34699/65. Heading G1U. In an apparatus for measuring a temperature variable resistance 2, the resistance is connected across a first constant current generator TR1, while a reference resistor R4 is connected across a second constant current generator TR2. A comparator arrangement constructed so that it does not significantly effect the currents through the resistors is arranged to measure the difference in potential across the resistors. The constant currents to the resistors are provided in the collector circuits of transistors TR1 TR2, by biasing their bases by a constant voltage from a Zener diode Z1. The comparator arrangement operates by applying the difference in the collector voltages of TR1 and TR2 to the base emitter junction of a high gain transistor TR3 and connecting the collector of this transistor to the emitter of TR2 through a meter 1. The base current drawn by the transistor TR3 is small, so that the currents through resistors 2 and R4 are not significantly affected by the presence of the comparator. Any increase in current through the meter 1 and resistor R5 is compensated by a fall in current through TR2.
