Title: Improvements relating to prepayment mechanism
IPC: G07F15/08
Filed: 1943-10-21
Abstract: 571,302. Prepayment mechanism for meters. METERS, Ltd., BARNES, H. V., and MITCHELL, H. H. Oct. 21, 1943, No. 17362. [Class 27] Price-change mechanism for coin-freed meters of the kind in which one member of a differential gear is rotated by the metering mechanism to cut off the commodity supply, comprises a change-speed gear in the drive between the metering mechanism a and the shaft b driving the differential gear member (not shown), the change-speed gear being so controlled that in one part of its revolution it drives shaft b at a high speed and in another part at a low speed, the ratio of the said parts being adjustable to effect price changes of the commodity being metered. In the construction shown a frame e fixed on a shaft c carries a shaft f having fixed thereon a drum i, a star-wheel h normally locked by a lever s pivoted on a shaft p on the frame e, and a bevel gear g driven by the meter shaft a through bevel gears o, o<1> loose on the shaft c. The drum i is connected by a ratchet clutch j with a pinion k meshing with a fixed circular rack m, around the periphery of which is an adjustable price-change ring t normally locked by a detent z and carrying a cam u adapted to be engaged by a roller r on an arm q fixed on the shaft p. When a coin has been inserted and the meter drives the shaft a, the star-wheel h and shaft f being locked, the frame e rotates with the bevel gear o<1> and the shaft b is driven at a comparatively high speed until the roller r engages the cam u and the lever s is rocked by the arm q to release the star-wheel. The shaft p being now free to rotate drives the pinion k through the ratchet clutch j, and the frame e and shaft c now rotate at a low speed. When the roller r reaches a fixed cam v the lever s is depressed to lock the star-wheel again. This lever is kept in either of its end positions by a spring catch y. The relative proportions of the high and low speed drives are changed by adjusting the position of the ring t, a pointer t<1> indicating what the price is. According to the Provisional Specification the change of gear ratio is effected by axial movement of the shaft p, this shaft in one position having a pinion engaging the fixed rack m and in the other position being locked against rotation on its own axis.

Abstract: 1283176 Cooling towers BROWN BOVERI & CO Ltd 27 May 1971 [20 Aug 1970] 17398/71 Heading F4K A cooling tower packing element consists of a splash plate 1 to the lower end of which a lattice or grid-like structure of non-interwoven vertical and horizontal rods 3 and 4 is suitably connected. Water from a distribution channel 5 flows downwardly through an inclined pipe 6 to impinge against the splash plate and spread outwardly to produce a stable liquid film which flows down over the lattice structure. The rods can be made of metal, ceramic or plastic material and may be joined by soldering, welding, gluing or sintering. Circular or rectangular crosssection rods can be used. In a preferred arrangement the elements are arranged in the tower substantially radially between inner and outer concentric walls (see Fig. 3); the cooling air then flows radially inwardly towards the centre of the tower in cross-flow relation. Adjacent elements may be staggered with respect to one another (see Group B, Fig. 3) or be arranged in zig-zag fashion (see Group C, Fig. 3). Alternatively, the elements may be disposed in a volute-like arrangement (see Group D).

Title: Improvements in or relating to the feeding of sheets of material to machines
Inventor: THOMPSON JACK EVANS
IPC: B65H29/66
Filed: 1959-05-27
Abstract: 911,047. Feeding sheets. THOMPSON & CO. Ltd., R. D. H. Aug. 26, 1960 [May 27, 1959], No. 18116/59. Class 100 (1). Apparatus for feeding sheets of material to a machine comprises means for feeding the sheets 4 into a pile from underneath the pile, a plate 6 spaced above the pile, a back lay 8 transverse to and adjacent to one end of the plate, means for blowing gas streams on to the underside of the plate 6 so as to blow the topmost sheets of the pile against the back lay 3 and to hold them in a state of suspension, floating and separate from one another, and means for engaging the floating sheets and feeding them one at a time towards the machine. Feeding belts 2 run up an inclined ramp 1 at the upper end of which is a vertical wall 3. The pile of sheets is disposed between the wall 3 and the back lay 8. Rollers 10 are mounted at the lower end of the back lay. A drum 11 having rubber suckers 12 located around its periphery is mounted above the plate 6, the suckers 12 projecting through a hole 7 in the plate when the drum is rotated. As each sucker passes through the hole 7 it is connected, via a hollow shaft upon which the drum is mounted, with a source of suction. At the front end of the pile a horizontal pipe 18 having nozzles 19 is mounted. During operation, compressed-air is blown continuously through the nozzles 19 whereby the top sheets of the pile are separated from one another and are held suspended in the air streams. As the drum 11 rotates the suckers 12 engage the topmost floating sheet and move it horizontally into the nip of feed rollers 24. Feeding belts 2 are driven intermittently and are started by a change in a predetermined capacity between two capacity heads 21, 23, such capacity varying in accordance with the number of sheets disposed between the plate 6 and the ramp 1. The pile of sheets is thus replenished as it becomes depleted by fresh sheets fed to the bottom thereof by the belts 2.

Title: Improvements in radio receivers comprising means for suppressing aperiodic disturbances
IPC: H03G11/04
Filed: 1939-06-21
Abstract: 524,193. Wireless receiving systems. PHILIPS LAMPS, Ltd. June 21, 1939, No. 18142. Convention date, June 24, 1938. [Class 40 (v)] A receiver incorporating means for suppressing a periodic disturbance comprises a highfrequency mixing valve 12 which supplies intermediate-frequency oscillations through a band-pass filter 13 to an intermediate-frequency amplifying valve 14. This supplies a lowfrequency amplifying valve 29 which is connected by a switch 10 to a final amplifying valve 38 to which is connected a loud-speaker 6. The anode circuit of valve 14 includes an oscillating circuit 15 of an intermediate-frequency bandpass filter 17, which is connected through condensers 18, 23 and 24 to the diode-anode 19 and cathode 25 of valve 29. The D.C. voltage set up by detection across a resistance 20 is supplied to the control grids of valves 12 and 14 and serves for automatic volume control. The oscillating circuit 16 of filter 17 is connected to diode anode 26 of valve 29 through a circuit including a resistance 28 to the cathode 25. The low-frequency voltages set up by detection across resistance 28 are supplied through a slide contact 30 to control grid' 32 of valve 29. A cathode ray tuning indicator (not shown) is also supplied from resistance 28 through resistance 33 and condenser 34. The band-pass filter 13 is connected to a valve 41 essentially similar to valve 14 and the output voltage of which is substantially constant since that control grids of both valves are interco nnected. The anode of valve 41 is connected through a band stop filter 7 to the anode 51 of a duo-diode 53, the anode 49 of which is connected to the anode of valve 14. The anode 51 is connected to the control grid 60 of an amplifying valve 61 in the anode circuit of which is included the relay 9 controlling switch 10. Under normal conditions diode 51, 52 does not rectify and control grid 60 is at earth potential. An aperiodic disturbance whose amplitude exceeds that of the high side-band frequencies will surpass the threshold voltage across resistance 54 and be rectified by diode 51, 52. Thus anode 51 and hence grid 60 acquires a negative potential causing a decrease in the anode current through relay 9, to render the lowfrequency amplifier temporarily inoperative. An arrangement is also described Fig. 3 (not shown) in which a second duo-diode is interposed between valves 53 and 61 whereby the threshold value above which disturbance elimination takes place is dependent on the side-band frequencies which correspond to the high modulation frequencies and is limited by the carrier wave of the desired signal.
