Title: Improvements in tea rolling machines
IPC: A23F3/12
Filed: 1928-05-08
Abstract: 312,473. Worthington, W. R. May 8, 1928. Tea, rolling. - In a tearolling machine of the kind in which the table is oscillated eccentrically in a horizontal plane and a tea receptacle arranged above. is adapted to maintain the tea in column form in contact with the table, from which the tea passes in rolled form, means are provided so that the pressure is applied to the tea under treatment automatically and periodically. As shown, the presser 3 which rests on the tea in the receptacle 2 is arranged to be periodically and automatically pressed down through a rocking-lever 37 and a push-rod 17 that is operable by a cam 16 loosely mounted on a shaft 14. This shaft carries a toothed segment 24 which gears with a toothed segment 26 on a wheel 11, and this worm wheel is driven from the main shaft 9 of the machine through worm-gearing. As the wheel 11 is rotated, the pinions 24, 26 periodically engage, the shaft 14 being rotated and, through the clutch 21, moving the cam 16 to raise the rod 17 and exert pressure on the tea through the lever 37, rod 43 and presser 3. A pawl 27 engages ratchet teeth on the boss 29 of the cam 16, which is thus maintained in the raised position after the segmental pinions 24, 26 have become disengaged by the continued rotation of the shaft 6. The pawl is disengaged by a lug 31 adjustably secured to the pinion 11, the lug moving into engagement with a projection 30 on the shaft 25 carrying the pawl; the cam 16 then drops to its lower position, and the pressure exerted on the presser 3 is interrupted until the pinions 24, 26 again move into engagement.

Patent GB-438961-A (GB)
Title: Improvements in ionic amplifier
IPC: H01J17/56
Filed: 1934-05-04
Abstract: 438,961. Thermionic valves. RUBEN, S., 265, Storer Avenue, New Rochelle, New York, U.S.A. May 4, 1934, No. 13545. Convention date, May 5, 1933. [Class 39 (i)] In an amplifier containing an ionizable medium, a control grid is arranged at a distance from the cathode not greater than the cathode fall space, a shielding electrode between the control grid and the anode is arranged close enough to the control grid to prevent ionization between the grids, and the anode is at a distance from the cathode greater than the cathode fall space. A controllable electron discharge is thus produced, the space charge being reduced by ionization, and a high output is obtained with a potential of 250 volts on the anode. The filling may be mercury to which may be added sodium or potassium, or a monatomic gas such as neon, argon or helium. As shown, an indirectly-heated cathode 2 is surrounded by a helical control grid 3, a helical shield grid 4, and a cylindrical anode, 5 which may be corrugated and tapered upwardly. The spacing of the turns of the control grid should be not greater than twice the cathode fall space length, so as to prevent the discharge through it of uncontrolled electron emission ; the shield grid may have the same spacing. Dimensions are given. The discharge is confined to the space between the cathode and the anode by mica plates 7. The envelope is coated. with carbon.

Abstract: 1,016,414. Double glazed units. J. P. KOBLENSKY. April 3, 1964, No. 13883/64. Heading E1R. In a double glazed unit the panes 12 are bonded by adhesive 14 to a flexible spacer gasket 13 which contains a one-way flipper valve 15, see Fig. 4 (not shown) to allow air to be squeezed out from the space when the panes are forced towards each other and to prevent air from entering when the panes are forced further apart by the resilience of the gasket, thus creating a partial vacuum. The unit may be clamped in a channel edging strip 11 by the panes pressing against the channel side walls which may be separated by a heat-insulator 16.

Title: Stick Masses for Pharmaceutical and Cosmetic Preparations
IPC: A61K9/02
Filed: 1968-03-22
Abstract: 1,189,237. Pharmaceutical and cosmetic bases. FARBWERKE HOECHST A.G. 22 March, 1968 [22 March, 1967], No. 14020/68. Heading A5B. [Also in Division C3] A base composition for pharmaceutical and cosmetic sticks comprises a mixture of a polyalkylene glycol ether of a C12-22 fatty alcohol and a polyalkylene glycol ester of a wax acid, the polyalkylene glycol components being synthesised from 2 to 100 molecules of ethylene oxide, propylene oxide or butylene oxide. Suitable fatty alcohols are lauryl, myristyl, palmityl, eicosyl, behenyl, oleyl, linoleyl and linolenic alcohols. The wax acid contains 22 to 36 carbon atoms and may be natural or synthetic. Examples are behenic, lignoceric, cerotic, montanic, triacontanic and mixtures such as those obtained by oxidising crude montan wax with chromic acid. The proportions of ether to ester may vary from about 9:1 to 1:9 by weight. The compositions are particularly useful when the active ingredient is acidic, e.g. boric, salicylic and linolenic acids and aluminium salts, particularly Al 2 (OH) 5 Cl. Other ingredients which may be present are mono- and polyhydric alcohols, water and polyethylene glycols.

Title: Improvements in or relating to voltage amplitude detection apparatus
Inventor: SHARP JOHN JOSHUA
IPC: G11B5/02
Filed: 1959-04-24
Abstract: 924,352. Pulse circuits. INTERNATIONAL COMPUTERS & TABULATORS Ltd. April 11, 1960 [April 24, 1959], No. 14035/59. Class 40 (6). [Also in Group XIX] Voltage amplitude detection apparatus comprises a first amplitude detection circuit producing a first output each time an input signal exceeds a reference level, peak detection means producing a second output on each occurrence of a peak in the input signal, an output being generated when the first and second outputs are concurrent. As shown, signals from the magnetic reproducing head 4 are amplified at 5 and fed as unidirectional voltages to the grid of a cathode follower 9. The diodes 7, 8 may be replaced by a pair of cut-off valves having a common load. The output from the cathode follower 9 is D.C. restored with respect to a positive reference voltage at terminal 16 by elements 12, 14, 15, and passed via diode 19 to the grid of valve 13. The positive parts of the waveform are clipped by diode 17 so that only the negative parts having an amplitude greater than that of the level of the reference voltage 16 are used to cut-off valve 13, providing positive pulses at the anode. These are fed via cathode follower 21 to diode 23 which forms part of an AND gate. The waveform at the cathode of valve 9 is differentiated by capacitor 25 and resistor 26 before being fed via an amplifier 24b to a multiar circuit 30. Amplifier 24b is provided with feed-back via a cathode follower 24a to improve the differentiation. Valve 30 is normally conductive so that diode 32 is normally cut-off by grid current in the resistor 35, hence the regenerative feed-back loop via transformer 31 is normally broken. When the anode of valve 24b goes negative, diode 32 becomes conductive so that valve 30 is rapidly regeneratively cut-off. The positive pulse so generated is fed to diode 36 of the AND gate, so that an output is obtained at lead 45 only if positive waveforms are concurrently fed to diodes 23, 36.
