Title: Improvements relating to cast-off buckles for belts for personal wear
IPC: A44B11/00
Filed: 1946-01-12
Abstract: 606,311. Hook fastenings. WALKER, Ltd., T., WALKER, T., and WOOD, H. H. Jan. 12, 1946, No. 1124. [Class 44]' [Also in Group VII] In a cast-off buckle of the type which is detachably connected to the inner end of the belt by a hook, stud or the like engaging a bar, slot or the like, and which can therefore be disconnected without having to detach the outer end of the belt from the buckle, inadvertent release of the hook is prevented by a spring blade or tongue. A buckle 1 has hingedly attached to it a plate 2 provided with a transverse slot 3 leaving at the outer edge of the plate a cross-bar 4 at the ends of which are integral extensions 5 forming lugs which support a keeper bar 6; the slotted part and cross-bar are bent back slightly relatively to the inner part of the plate 2. The cross-bar 4 is detachably engaged by a hook 8 on a plate 9 to which the inner end 10 of the belt is attached; this hook 8 is formed by folding back an extension of the plate 9, the extension having a rectangular aperture 12 so that the hook is U-shaped, comprising a bar 8a carried by two side arms. A spring tongue 13, cut out from and bent to lie in front of the plate 2 beneath the keeper bar 6, extends across the slot 3 and bar 4 and is cranked at its outer end so that it is close to the bar 4. When the hook 8 is engaged with the bar 4 the end of the tongue 13 wipes over and engages behind the inner edge of the bar 8a of the hook, which is thus securely held. Instead of using a hook, a stud may engage a keyhole slot in the plate attached to the buckle and be retained in the narrower part of the slot by a spring tongue.

Abstract: 1507621 Centrifugal blowers MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 13 Jan 1976 [4 Feb 1975 6 Feb 1975 (2) 27 Feb 1975] 01201/76 Heading F1C A suction cleaner blower impeller 4, Figs. 1, 2 and 5 discharges to a number of volute passages 9 each having a spiral wall 11 which diverges from the impeller periphery in the direction of impeller rotation. Each volute passage 9 leads via a downwardly directed channel 10, see also Fig. 8, to a corresponding passage 12 leading radially inwardly to an opening 2a leading into the casing of the driving motor 2. After passing around and cooling the motor, the air is discharged via one or more outlets 2b. Noise arising from the passage of the impeller blades past the exit ends of the volute passages 9 is reduced by partially covering each exit end by a sloping extension 11a of the wall 11 of the following volute passage, whereby the transition between each volute passage and the next is made less abrupt. The length of each extension 11a is greater than the distance between successive impeller blades. In a modification, Fig. 18, each extension is made considerably longer and comprises a sloping portion 111c and a portion 111d of constant height, short transition portions 111b and 111b' being provided. The blower may have two stages.

Title: Improvements in or relating to flexible couplings for shafts and the like
IPC: F16D3/77
Filed: 1945-01-16
Abstract: 594,550. Universal joints. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., McLEOD, R. C., and FIELDEN, G. B. R. Jan. 16, 1945, No. 1356. [Class 80(ii)] [Also in Group XXV] In a flexible shaft coupling adapted to sustain axial load through an element adjustable to maintain a predetermined spacing between the shaft ends, adjustment of the element in one sense to vary its axial loading effects automatic extraction of one or both shafts from the coupling. As shown, two disc-like flexible radius members 5, 6, Fig. 2, bolted together at their peripheries, drivingly interconnect hollow compressor and turbine shafts 1, 3 respectively, being splined thereon and held axially against removal by screwed ferrules 31, 32 themselves secured by circlips 33, 34. A bolt 11, whose head 35 bears internally on the ferrule 32, is screwed into the ferrule 31 on rotation by a suitable tool inserted into the hollow shaft 3, and acts to draw the coupling together and to tension itself, being held in the correctly adjusted position by a locking ring 36 which screws into the ferrule 32 and is axially grooved internally to co-act with radially spring-pressed balls 37 in the head 35. Unlocking the ring 36 and screwing the ferrule 32 towards the coupling forces the shaft 3 out of the member 6, and, if the two threads on the ferrule 31 are oppositely handed, similar rotation of the rod 11 then forces the shaft 1 out of the member 5. In a modification automatic extraction of shaft 3 alone is provided. One radius member 6, Fig. 1, is secured to a ferrule 9, the other 5 being bolted in position on its splines. The head 12 of the bolt 11 is anchored in the shaft 1, and the bolt passes through the ferrule whose f r e end is clamped between a shoulder on the bolt and a nut 27, shims being inserted so that the shaft 3 abuts the member 6 when the coupling is correctly tensioned. Tension is applied by a nut 15 bearing on an internal shoulder in the shaft 3 and rotated by an extension member 18, Fig. 1A, passing right through the shaft 3 and splined at its outer end to take a suitable tool. Vernier locking of the nut 15 is provided by an axially inserted ring 21 having a slightly differing number of internal and external splines co-acting with the splined end of the member 18 and with a dog (not shown) on the shaft 3 respectively. The ring 21 is retained by a nut 22 secured by a tab washer. A flange 19 on the member 18 having enough axial play in the shaft 3 to allow tensioning of the coupling is brought against an internal shoulder in the shaft upon sufficiently unscrewing the nut 15 and withdraws the shaft, the ferrule 9 preventing the member 6 from following. Passages 30 supply lubrication to the rubbing faces of the nut 15 and flange 29, the latter being also ported to allow cooling air drawn in at openings 29 to pass to the turbine rotor.

Filed: 1973-01-11
Abstract: 1420643 Projection printing MINNESOTA MINING & Mfg CO 11 Jan 1973 [12 Jan 1972] 1600/73 Heading G2A A card feeding mechanism for feeding aperture cards 14 in turn from a stack 52 to a scan projection area includes a feeding mechanism, and a movable platen 76, to which the cards are fed and then held by clamping plate 108, wherein the plate 108 is biased to the clamping position but is moved to the release position when a card 14 is fed to the platen 76 and the clamping plate can be manually moved to the release position to permit manual substitution of a card 14 on the platen 76. Feeding of a card 14 to the platen and simultaneous ejection of any card 14 from the platen is controlled by cam 162, Fig. 6, and follower 168. The motor 140 is initially energized by closing a switch (not shown). This rotates shaft 160 and causes follower 184 to lift out of detent 190 thereby turning shaft 128 to close switch 188 and keep the motor 140 energized. This movement of shaft 128 also moves arm 126, Fig. 3, to release clamping plate 108 by means of its end 124 engaging arm 120 extending from the plate. The spring- bias of the plate 108 is provided by springs 118. Finger 132 extending from the plate 108 permits its manual movement. Completing the revolution of shaft 160 closes switch 188 to stop the motor 140 and clamps the plate 108. While the plate 108 is released, cam 162 also rotates to open the gate 114 and engages drive to roller 66 sufficiently long to feed one card 14 from the stack 52 on to the platen 76. Rollers 110, 112 remove any card already on the platen when the plate 108 is released and gate 114 opened. Drive for the scan exposure movement of the platen 76 is derived from shaft 90 driving a belt 96 carrying a bar attached to the carriage 80 carrying the platen 76. The carriage is driven in one direction only and returned by spring cord 106.
