Title: Improvements in or relating to blind-riveting
Inventor: HENSHAW JAMES NORMAN

Abstract: 1279256 Riveting; making blind rivets; angular bending GEORGE TUCKER EYELET CO Ltd 19 Nov 1969 [20 Nov 1968] 54971/68 Headings B3A B3E and B3U In a blind riveting method, the mandrel stem S is pulled axially in a direction inclined at 15- 25 degrees to the rivet axis so that after setting of the rivet the mandrel breaks at a position where it emerges from the rivet head. In operation, the mandrel is inserted through a hole 40 of an abutment 36 and between jaws 30 and the rivet head is seated against a frustoconical face 38 of the abutment 36 having an axis of revolution inclined at 20 degrees to the hole 40. The rivet is frictionally held by a spring steel retainer 46. On retracting the mandrel gripping jaws 30 by an hydraulically operated piston-rod 12, the mandrel is pulled over a radiused edge bounding the hole 40 and eventually breaks at a position substantially flush with the rivet head. The nosepiece 16 to which the abutment 36 is secured, is adjustable about its axis. The disposition of the nosepiece 16 allows access of the tool to restricted spaces (Fig. 5, not shown). The rivet may be open or closed ended. The mandrel stems S are bent by feeding blind riveting assemblies down an inclined raceway comprising spaced bars 52, 54. The lowermost rivet assembly is arrested by a block 72 and the tubular portions of four assemblies are pushed over by a pneumatic piston and cylinder operated pusher 74 so that the mandrel stems are bent to an angle of 20 degrees with the rivet axes. The bent assemblies are then able to pass the block 72 to allow the next four assemblies to arrive at the bending station.

A liquor is concentrated by passing it via pump 5 through heat-exchanger 2 wherein it is heated and partially evaporated by hot liquid such as water (or the vapour thereof), the mixture of concentrated liquor and vapour enters separator 6 from which the concentrated liquor is withdrawn by pump 7; the separated vapour (or some of it) flows to heat-exchanger 3 where it is partly or wholly condensed by heatexchange with a liquid refrigerant (e.g. ammonia) which is vapourized thereby, the vaporized refrigerant is drawn into compressor 10, the compressed vapour is used to heat the liquid required for circulation by pump 4 through heat-exchanger 2, and the condensed refrigerant is returned via expansion valve 11 to heat-exchanger 3. The evaporation of the liquor may be effected under reduced pressure by means of ejector 8. Heat-exchanger I may be made of inexpensive carbon steel, and preferably has finned tubes. Heat-exchangers of the plate type may be used. Compressor 10 may be driven by a Diesel engine or a gas turbine, the waste heat of the engine or turbine being utilized for heating the liquid before and/or after it flows through heat-exchanger 1. An apparatus is described with Fig. 3 (not shown) wherein the liquor leaving heatexchanger 2 passes through a series of flash evaporation chambers, and the vapours withdrawn from these chambers (except the last two) are condensed by heat-exchange with the feed liquor flowing to heat-exchanger 2. The vapours withdrawn from the last two flash chambers are utilized to vaporize the liquid refrigerant in heat-exchanger 3 and in a further heat-exchanger. In another embodiment (Fig. 2-not shown) there is disposed, between heatexchangers 2 and 3, a series of heat-exchangers in which the liquor and separated vapour exchange heat, and further evaporation of liquor takes place.

Abstract: 1,176,290. Winch drives. UNITED AIRCRAFT CORP. 18 Dec., 1968 [11 Jan., 1968], No. 60065/68. Heading B8B. A cargo hoist system for a helicopter comprises a hoist drive shaft 54 driven from a main rotor drive shaft 10 during cargo lifting, through a first one-way clutch 38, the rotor shaft 10 being driven by the hoist drive shaft 54 through a second one-way clutch 78, to retard the free fall of cargo being lowered by the shaft 54. For cargo lifting, a shaft 32 driven through gearing 12, 34 from the shaft 10, drives a gear 44 on the engaged clutch 38, which is of the ball and cam type. Gear 44 drives shaft 54 through gear 50, shaft 52, gears 59, 64 and clutch B, shaft 52 being coupled to a gear 36 on the shaft 32 through a second path comprising the second one-way clutch 78 having a gear 76. The clutch 78, also of the cam and ball type, overruns during cargo raising since the gear ratios 44, 50 and 76, 36 are arranged such that the casing of clutch 78 rotates faster than the cam thereof on the shaft 52, whereupon the ball does not lock and cam and casing. For cargo lowering, the shaft 52 is driven in the same direction as for raising, by the shaft 54 through a clutch A and as the rotational speed of the shaft 52 exceeds that of the clutch casing 78 being driven by the rotor shaft 10, the clutch 78 engages and acts to retard the lowering velocity of the cargo. During this operation the clutch 38 overruns due to the aforesaid gear ratios. The hoist may be operated while the helicopter is on the ground, by an auxiliary power unit 72 through a clutch 74, the one-way clutch 78 having been locked into a free wheeling mode by lever 88, whereupon one way clutch 38 will overrun.
