Title: Improvements relating to suction cleaners
IPC: A47L9/20
Filed: 1947-12-23
Abstract: 669,542. Filters for suction cleaners. HOOVER, Ltd. Dec. 23, 1947 [Dec. 28, 1946], No. 34016/47. Class 8 (ii) In an arrangement for shaking the filter of a suction cleaner to remove the accumulated dirt. the filter bag 33 is clamped at one end 36 and the other end is supported on each side by a pair of parallel links 42, 50 pivoted to a yoke 47. The bag is kept taut by a pair of torsioned springs surrounding the pivot 45 of the link 42 and a flexible member 62 is connected to the yoke 47 and to an anchored spring 65. A bell crank 67 is secured at 70 to the flexible member and carries a pin 71 that is engaged by a surface carried on a spring-loaded bell crank 79 provided with a pedal 61. When the cleaner is positioned for emptying, the pedal is depressed and the bell crank 67 is moved to collapse the bag until the pin 71 rides over the operating surface when the bag snaps taut. A similar operation occurs when the pedal is released. In a modification, the parts are arranged to pluck the flexible member transversely. Specifications 612,223, 643,083 and 654,107 are referred to.

IPC: B62J17/00
Filed: 1921-12-17
Abstract: 196,025. Owen, H. E. Lloyd-. Dec. 17, 1921. Weather-screens. - A weather-screen for use with motor-cycles comprises a flexible apron carried by a support mounted upon the frame or other fixed portion of the cycle, and pivoted to permit of adjustment in a longitudinal direction or to fold down over the saddle. In Fig. 3<a>, the support consists of two parallel members 8, pivoted at 8<a> to a clamp on the petrol tank, and provided with telescopic extensions 8b, and a telescopic strut 10. The extensions 8b carry a transparent screen 12, and a bar on to which is threaded the top of the flexible apron 16c, Fig. 1. The apron, which has lateral extensions 16d, is fixed at the bottom to rigid Jeg shields 4, Fig. 4, forming part of the engine cooling means 1, Fig. 1, below which a splash guard 5, Fig. 4, is fitted. In alternative constructions the support members 8 may be divergent or convergent, or a single post may be employed. The strut 10 may be fixed to the frame, steering column or handle-bar, or it may be replaced by a flexible guy, or dispensed with altogether. The rigid leg shields 4, Fig. 4, may be replaced by extensions of the flexible apron attached at 3 to engine cooling means 1, and when the cycle is provided with foot-rests instead of boards, the lower end of the splash-guard 5 may be attached to the underside of these rests, or to an adjacent brake. Various fixing details for the supports and strut are described.

IPC: B60G11/113
Filed: 1921-12-21
Abstract: 191,590. Woodhead, G. A. Dec. 21, 1921. Laminar springs.-In laminar springs in which the second plate is carried the full length of the main plate and is adapted to function as a main plate in the event of a fracture of the latter, the main plate 2 of the spring is formed at the side of each end with an integral lug 4 secured by means of bolts 6 to the axle flan 5 and so formed as to project above the plate 2 to act as a guide for the second plate 7. An extension of the second plate 7 is formed of reduced width to pass between the lugs 4, its end being turned down over the end of the main plate 2, or being hooked to engage beneath the axle flan. A transverse plate 11 connecting the lugs 4 and a clip 9 guide the second plate 7 and permit longitudinal movement relative to the main plate 2. When the plate 7 acts as a temporary main plate. this movement is limited by its end 8 and shoulders 12 which engage the lugs 4. The main plate mav have two lugs 14, Fig. 6, at each side, in which case the shoulders on the second plate are dispensed with and a slot 16 is cut therein to accommodate the head of a screw 15 which assists in securing the main plate to the axle. The third plate mav be bent upwards at its end 18 so that, if the main plate is fractured, movement of the second plate is limited bv the abutment of the end 18 against the transverse plate 11.

Abstract: 1,248,540. Steering directional acoustic beams. FRIED. KRUPP G.m.b.H. 10 July, 1969 [11 July, 1968], No. 34794/69. Heading H4D. In a system for steering a focused acoustic beam radiated from a plane array of i equidistant transucers 5, the transducers are energized at respective frequencies f n  = f 1  (n - 1)#f, where n = 1 to i and #f is a frequency increment, through respective band-pass filters 4 which are fed with ringing pulses from a transmitting device, said device comprising a generator 1 of pulses at a repetition frequency 0À5f 1  which trigger a cascade connection of monostables 2, each having an infinitely variable unstable state duration #t, the trailing edges of the monostable output pulses being used to trigger further monostables 3, each having a fixed unstable state duration of 0À5/f 1 . Start and stop signals trigger bi-stable 8 which in turn opens and closes gate 7 to determine the time for which an acoustic signal is radiated. The beam direction is a function of #f and hence of #t, and is steered by applying a control voltage from potentiometer 10 or from function generator 6 to monostables 2 to vary #t. A threshold device 9 may be used to terminate the acoustic transmission when the beam deflection reaches a predetermined limit.

Abstract: 602,922. Fishing-reels. FRENY, R. Dec. 27, 1945, Nos. 34981 and 34982. Convention dates, Jan. 10, and April 20. [Class 48] A stationary spool reel has a device comprising balls or rollers and a cain which precludes rotation of the flyer-drum in the direction of unwinding. The balls 62, Figs. 3 and 4, are housed between a ring 64 on the reel body and the cam 90 on the flyer-drum. A ring 65, Figs. 3 and 5, having restricted angular movement with respect to the drum has flanges 68 engaging the balls. The angular position of the ring is controlled by a lever 81 pivoted at 83 and connected by a spring-loaded sliding rod 27 to a plate 24 carrying a line guide 23. In the position of the mechanism shown in Fig. 5 the line guide and the balls are inoperative, the balls being pressed against shoulders 60 by the flanges. Rotation of the drum in the winding direction causes a pin 25 on the plate to engage with a spring 85 on the reel body thus setting the line guide and releasing the balls, In a modification the spring may be replaced by a projection on the reel body. The Specification as open to inspection under Sect. 91 describes also a fishing reel in which the flyer drum 4, Fig. 1 (Cancelled) may be prevented from rotation in the direction of unwinding by a pawl 19 co-operating with the toothed wheel 20 and controlled by a lever 16. The spool 3 is frictionally coupled to a non- rotary shaft 7 and means are provided to give audible warning of the spool rotation. The flyer drum is balanced by weighting a boss 21. This subject-matter does not appear in the Specification as accepted.
