Title: Methods for the manufacture of mica products
IPC: C04B14/20
Filed: 1952-11-12
Abstract: 755.504. Ornamenting. LICENTIA PATENT-VERWALTUNGS-GES. Nov. 12, 1952 [Nov. 12, 1951] No. 28508/52, Class 93 [Also in Group VIII] Mica products consisting of one or more layers of mica laminations bonded to a support surface are prepared by a method characterized in that the individual mica laminations are subjected to the effect of electrostatic forces on their way from a tray or feeding device to a glued surface of a plate, sheet, web, or the like to which the laminations are to be applied. In Fig. 2 mica flakes are fed along earthed band 5 and under effect of the counterelectrode 7, connected to a high potential source, impinge on moving glued surface 6, e.g. paper. In Fig. 3 mica flakes are fed along shaking earthed electrode 8 and are attached to glued band 10 secured round rotating drum 9 connected to a high potential source. Earthed discharge electrode 13 applies an electrical wind to secure the flakes flat on the surface. Further mica layers may be applied by mechanically spraying, or electrostatically atomizing, binding agent through nozzles 11, while discharge electrodes 13 apply the potential of the drum to the mica layer. In Fig. 4 mica flakes are fed along earthed electrode 14 and are attracted to endless band electrode 16, whence flakes butter down on to glued band 17, which may also be earthed. In Fig. 6 flakes are fed down earthed plate 26 and fall in a zig-zag path through the space between high potential counter electrode 22 and earthed plate 23. Discharge members 37, 35 may charge the flakes and the flakes flutter on to surface 28. Where discharge member 37 is used, feeding track 26 may be insulated. A charged atomized glue cloud may also be sprayed from 36 into the flakes where multi-layer products are required. In Fig. 7, mica is fed along electrode 30 and deposited on glued band 33 before it can reach counter-electrode 31. The counter-electrode may alternatively be immediately below the band. In other apparatus not shown (Figs. 1 and 5), mica on a tray is deposited on a glued backing by moving a counter electrode back and forth behind the backing or the electrode and counter-electrode are plates at a diverging angle with a glued backing positioned below. The application of high potential to the electrodes may be inturrupted periodically.

Title: Improvements in or relating to the manufacture of phenanthridine compounds
IPC: C07D221/12
Filed: 1948-11-03
Abstract: Quaternary salts of 3-amino-9-phenyl-phenanthridine containing a urethane group in p-position of the 9-phenyl radicle are obtained by reduction of a 3-nitro- or hydrolysis of a 3-acylamido compound of the corresponding formula.  The 3-nitro-9-phenyl-phenanthridine having a urethane substituent in the 9-phenyl ring is obtained by ring-closure of the nitrosubstituted diphenyl having a urethane-substituted benzoylamido-group in p-position, is converted to the quaternary phenanthridinium compound and reduced.  The urethane group may be hydrolysed and further reacted with an alkyl chloroformate to give a different urethane group.  The nitro-group may be reduced and acylated before or after quaternization.  Examples describe the preparation of 3-nitro-9-phenylphenanthridinium 10 methyl sulphate, methyl chloride and methyl ethane sulphonate and sulphate, substituted in 9-p-position by carbethoxyamino-, and carbo - butoxyamino groups, by the routes described, from the initial diphenyl compounds.  The Provisional Specification describes also compounds in which the carboalkoxy group is in positions other than the para position.  This subject-matter is not contained in the Specification as accepted.

Title: Phonic motor drive for telegraph machines
IPC: H04L7/00
Filed: 1919-11-18
Abstract: 158,413. Murray, D. Nov. 18, 1919. Type-printing telegraphs; synchronous movements. - In a printing telegraph of the Baudot type driven by a uniformspeed motor such as a phonic motor, step-by-step means are provided for altering the phase relation between the type-wheel mechanism and the phonic wheel. An adjustable coupling between the phonic wheel 1 and the shaft 2 carrying the type-wheel comprises a sleeve 6 secured to the shaft by a set-screw 7 carrying pivoted at 8 on it a sickle-shaped lever 9, the top end of which has a pivoted pawl 10 engaging an internal ratchet-wheel 12 screwed to the phonic wheel. The coupling is rendered elastic by a spring 13 which pulls the lever against the wedgeshaped piece 14, which serves as a stop. A pin 15 is pushed into the path of the end 16 of the lever 9 by means of an electromagnet, the circuit of which is completed when a. rotary cam on the shaft 2 makes a contact at the same instant as a brush contact is made by the distributor. This pin holds up the lever 9 and causes the pawl 10 to move back over one tooth of the ratchet-wheel 12. A wedge-shaped piece 14 carried on the spindle 2 restores the pin 16 to its zero position. The coupling may be so adapted that the pawl jumps forward through a space of a tooth instead of slipping back. The device may be used with a distributor of the Baudot or other type driven by a phonic or other uniform-speed motor, the teeth of the ratchet-wheel in this case being more numerous and the corresponding phase correction smaller. Two pawls may be used, one shorter than the other by half a tooth, thus halving the number of teeth required. In multiplex working, in order to effect synchronism between the printer and the distributor at the station from which the distributor synchronizing-impulses are sent out, there must either be two separate vibrators, one driving the printer slightly faster than the other drives the distributor, or, using a single vibrator, the contact cam must be shaped to open its circuit momentarily once in a. revolution instead of closing it.

Abstract: 948,125. Measuring specific gravity. F. F. RIDLEY. Feb. 9,1960 [Nov. 9,1958], No. 28820/58. Heading G1S. A suspension of solids in liquid, for instance a suspension of a heavy mineral in water for use in a float and sink process wherein the lighter coal 6 is separated from the heavier stone and other foreign matter 8, has a tube 9 positioned in the suspension 2, or in a separate chamber through which the suspension is passed to isolate a quiescent column of water or other liquid which is in equilibrium with the remainder of the suspension and is free of the solids which separate out, the height of the column above the level of the suspension being a measure of the specific gravity of the suspension. The level may be measured by a direct scale, a pressure capsule or a float, or by measuring the pressure necessary to force air bubbles through the quiescent column from the bottom of a dip tube. A small supply of liquid may be continuously introduced into the quiescent column to maintain a slight downward flow which prevents suspension solids from entering the column. Specifications 563,754, 563,779 and 581,569 are referred to.

Title: Resuscitator
IPC: A61M16/00
Filed: 1951-12-10
Abstract: 710,724. Respiratory appliances. SEELER. H. Dec. 10, 1951, No. 28858/51. Class 81(2) In a resuscitator device comprising a casing, the interior of which is in communication with a jet pump actuated by compressed gas and a diaphragm-controlled valve is associated therewith which determines the flow of gas to or from a face mask, adjustable biasing means are provided for the diaphragm which determines the degree of pressure and vacuum at which the valve opens and closes respectively. Air or gas entering through connection 26, Fig. 3, passes an adjustable needle valve 44 and enters a nozzle 30 to produce a stream flowing through a venturi tube 28 to atmosphere through a screen 39. The tube 28 has ports 32 and a butterfly valve 33 so that pressure or suction can be produced in the main body 1 acording to the position of the valve. The interior of the body communicates, through a connection 36, with a face mask and, assuming the valve 33 to be initially closed, the pressure built up therein is communicated through ports 9, Fig. 2, to a diaphragm 5 which is thereby urged towards the left until the rod 12, carried by it, snaps over the valve crank 34 by a toggle spring 35, thus opening the valve. Suction through the ports 32 now reduces the pressure in the body 1 and face mask until the diaphragm is drawn back and the valve again closed. Loading springs 14, 15 adjustable by individual knobs 19, are used to determine the suction or pressure necessary before changeover of the valve occurs. It is suggested that for normal purposes an air supply should be obtained from a turbine driven blower operated by suction from a water supply arid that an oxygen supply, through a reducing valve, should be conected into the supply pipe immediately upstream of the resuscitator body. The pneumatic pad around the face piece communicates through a one-way inlet valve with the interior of the mask so that the maximum pressure in the mask is maintained in the pad.
