Abstract: 598,398. Transponders. FERRANTI, Ltd., TAYLOR, M. K., and WILLIAMS, F. C. Nov. 5, 1945, No. 29285. Drawings to Specification. [Class 40 (v)] In a transponder, a pulse of relatively high power is fed to the transmitting valve over a cathode follower, the normal potential of the cathode being maintained positive with respect to the grid. The cathode follower may be arranged to be normally in a cut-off condition to prevent operation by spurious low-amplitude pulses, and the oscillator cathode biassed positively to prevent undesired oscillation by resistors connected between the supply and the respective cathodes.

Title: Method of processing waste paper
Inventor: ALTMANN NORMAN A
IPC: D21B1/32
Filed: 1959-08-27
Abstract: 904,279. Producing clean pulp from waste paper. BUTLER CO. Aug. 27, 1959, No. 29305/59. Class 96. In producing clean pulp from waste paper, the latter is coarsely pulped in cool or cold water, e.g. in a beater or hydropulper, and then refined for a few, e.g. 1 to 5, seconds between the opposed, closely set, serrated surfaces of the discs of a high-speed refiner, e.g. of the kind described in U.S.A. Specifications 1,744,226 and 2,568,783, to reduce impurities, such as ink, starch and clay, into particles. The relative speed of the discs may be 18,000 feet per minute. The refined pulp is fed through a pipe 16 and a chamber 12, Figs. 4 and 3, into a U-shaped scrubber comprising a lower limb having a bottom wall 6 and an upper wall 7, a semi-circular end 8 and an upper limb 13 having walls 32 and 33, which converge to form an outlet 34. The scrubber has side walls 10 and 11. Jets of clean wash water are fed, at high pressure, e.g. 150 to 250 p.s.i., through perforations in pipes 20, 21, 22 and 23, into the refined pulp to disperse the fibres and particles of impurities throughout the water and lower the consistency of the pulp, which passes through the outlet 34 and is guided by an apron 15 on to the downwardly-inclined screen 36 of a dewatering device 35. As the pulp passes down the screen, water containing the impurities drains away and is guided by a draining board 37 into a sump (not shown), e.g. a settling tank, to be clarified. The cleaned pulp passes from the screen into a pulp chest (not shown). This pulp may be diluted with clarified wash water and passed through a second scrubber and dewatering device.

Title: Improvements in or relating to connectors
IPC: H01R13/62
Filed: 1962-08-01
Abstract: 972,735. Stud and socket fastenings. PYLE-NATIONAL CO. Aug. 1, 1962 [May 10, 1962], No. 29608/62. Heading E2B. [Also in Division H2] A coupling sleeve for locking together engaged plug and socket parts is spring biased axially of the plug and socket towards a locking position in which a locking element mounted on the plug is urged against a shoulder on the socket, the locking element being releasable by retraction of the coupling sleeve which may then be held back by a detent member. Fig. 1 shows the coupling sleeve 11 overlying a plug 20 and socket 21, which are held together by the engagement of locking tines 13 in a recess 16 in a socket ring 17. To release socket 21 the sleeve 11 is retracted against a spring 19 when outwardly biased tines 13 spring out of recess 16, aided if necessary by a flange 52 on the forward part 18 of sleeve 11. Detent tines 12 then engage in slots 14 in tines 13 to hold sleeve 11 back until the plug and socket parts are again coupled, when the socket ring 17 lifts tines 12 out of slots 14 and the coupling sleeve 11 slides forward into its locking position. Polarisation of the plug 20 and socket 21 is obtained by means of a key of multiple construction including members 32 to 42. A ring 32 has sixteen openings 33 with any one of which a key 34 on socket 21 may be engaged and also three keyways 34a in which is engaged one to three splines on a further ring 35 having sixteen slots 37 with any of which a key 37 on plug 22 may be engaged during the initial assembly. The ring 35 has a hook 39 which engages a ring 40 in groove 41. Spline 42 on the plug engages a guideway 43 in socket 21. In the locked position, a rubber seal 44 is compressed between the end of plug 20 and a socket shoulder 45. The operation of the connector is described schematically (Figs. 5, 6, 8 and 9 not shown) and alternative forms of detent mechanism (Figs. 2, 9 not shown) and of key structure (Figs. 3, 4, not shown) are disclosed.

Abstract: <PICT:0367341/III/1> <PICT:0367341/III/2> Liquids contained in trays in an evacuated porcelain chamber having a glass cover are concentrated by the absorption of aqueous vapour therefrom by sulphuric acid supplied through a valved-tube 13 having a filter 14 and a portion 15 of fine bore and flowing over the surface 2 of the false bottom of the chamber.  The chamber is evacuated by the pump 21 and the spent acid flows through an acid seal 25 to a water jet-pump 6, the water operating the pump being previously used to cool the underside of the surface 2.  In a modification, the chamber is connected to a quartz or acid-proof metal unit comprising coaxial tubes 2a, 26, Fig. 2, the space between which is supplied with acid through a pipe 13a and forms the absorption space, the jet pump 6, and the mercury vapour pump 30.

Abstract: 690,428. Printing. JOHNSON, J. A. Nov. 23, 1950 [Nov. 24, 1949], No. 30114/49. Class 100(ii) Bronzing and the like.-In a machine for applying colour to printed sheets such as ceramic transfers, wherein the colour in powder form is fed on to a sheet which is being carried forward on a moving support such as a rotary drum, after which the sheet is carried beneath reciprocating rubbing pads which cause the colour powder to adhere to the sheet in the pattern areas, which are coated with adhesive, the pads are mounted on bars which carry rubber or the like resilient inserts, through the medium of which the reciprocating motion is communicated to the bars. An electric motor drives the drum 10, Fig. 1A, through belt 37 and gear 41, while a second motor drives a fan to collect surplus powder, and a third motor drives eccentric rollers 12 to brush surplus powder from the sheet, and delivery rollers 60. The rubbing pads are carried on square-section bars 20, Figs. 1A and 3, reciprocated by means of rollers 28 engaging a cam ring mounted on the gear 41. Each bar 20 is hollow at one end and contains a rubber or like resilient insert 31. Mounted on a holder 30 is a spindle 29 carrying the roller 28, and a compressor stalk 27 engaging the insert 31 to convey the reciprocatory motion of the roller to the bar, the holder being slidable over the bar bearing 21 to an extent limited by a slot 30b and screw 30a. The other end of the bar is spring-loaded by being located in a housing containing a spring, a tension-adjusting screw enabling the amount of sliding movement of the bar to be controlled. Alternatively, the other end of the bar may be rubber-cushioned.

Title: Improved paper roll brake for rotary printing machines
IPC: B65H23/08
Filed: 1934-10-22
Abstract: 429,330. Feeding webs. MASCHINENFABRIK WINKLER, FALLERT, & CO. AKT.- GES., 36, Wylerringstrasse, Berne, Switzerland. Oct. 22, 1934, No. 30226. Convention date, Nov. 27, 1933. [Class 100 (i)] In web roll brakes for rotary printing machines, of the kind in which belts running at a slightly lower speed than the web are pressed against the roll and controlled automatically by the web tension, the pressure of the belts is adjusted by positively moving both ends thereof. The arrangement provides for rapid control of the web tension when the usual roll supporting frame, carrying the active roll and a reserve roll, is rotated to effect the web renewing operation. The belt pulleys 6, 7 are slidably mounted in the machine frame and moved by separate reversible electric motors 10, 11 acting through worm and screw gear. The motors are arranged in parallel and their circuits are controlled by relays 25, 26, the circuits of which contain contacts 17 between which moves a contact carried by a floating roller 19 resting on the web. As the roller 19 rises or falls due to variation of the web tension, a circuit is closed through one of the contacts 17 and one of the relays 25, 26 to drive the motors 9, 10 in the direction to restore the web tension to normal. To prevent excessive pressure of the belts on the roll, a number of switch levers 21 arranged at different heights are adapted, upon a certain pressure being exceeded to open one of a number of contacts 22 in series with the upper contact 17 and thus cause the stoppage of the motors. Contacts 23, in circuit with the lower contact 17, and also controlled by the levers 21 may be caused to open to stop the motors when the belt pressure is reduced beyond a predetermined minimum. The motors 9, 10 may be mechanically connected, e.g. by chain gearing.
