Title: An improved air bearing especially suitable for use in machine-tools and grinding machines
IPC: F16C32/06
Filed: 1950-03-07
Abstract: 671,158. Fluid bearings. SCHOPPE & FAESER FEINMECHANIK GES. March 7, 1950 [March 7, 1949], No. 5736/50. Class 12 (i). An air bearing, particularly for grinding- machines, machine-tools, &c., comprises a rotating part 1 axially and radially bedded by the bearing shell 2, 4. The cylinder 2 is enclosed by a further cylinder 3, both being the boundaries of an air chamber 7 connected to a compressed air pipe 6. The cylinder 2 is provided with jets (not shown) distributed uniformly over its surface and penetrating radially through it. A foil closes the cylinder 2 on its outside, and in line with the jets are outlets in this foil of about <SP>1</SP>/ 100  th the jet cross-section. The compressed air prevents contact of the rotating part 1 both with the cylinder 2 and also with the discs 4, through the latter of which jets may also or alternatively be provided. The rotating part 1 may form the squirrel cage of an electric motor, and one or more of the devices can be combined with an air stream turbine, the turbine and air bearing being connected to the same source of compressed air. The compressed air in the bearing may be replaced by any gas or gaseous mixture, or by steam.

Title: Improvements in or relating to titanium dioxide pigments
IPC: C09C1/36
Filed: 1942-05-01
Abstract: 557,877. Titanium pigments. BRITISH TITAN PRODUCTS CO., Ltd. May 1, 1942, No. 5918. Convention date, May 2. 1941. [Class 95] Chalking-resistant titanium dioxide pigments are prepared by intimately associating, in moist condition, particles of a titanium dioxide pigment with small amounts of chromium oxide or silicate, and with a white silicate of another metal, and with alumina. The preferred amounts of the additions are:- 0.03 per cent. - 0.07 per cent. of the chromium compound (calculated as Cr), 1.0 per cent.-3.0 per cent. of the white metal silicate, and 0.75 per cent.- 1.25 per cent. of alumina (calculated as Al 2  O 3 ), based on the weight of the original titanium dioxide pigment. Specified white slicates are those of barium, calcium, magnesium, aluminium, thallium, zirconium, titanium and tin. The original pigment may be formed into a slurry, and the additions all formed in situ, by precipitation. Examples are given of the treatment of pigments consisting of pure titanium dioxide, of titanium dioxide pigments containing about 1 per cent. of antimony, and of a composite barium sulphate-titanium dioxide pigment.

A cardboard sleeve 62 surrounds the sampler and thermocouple. The end of the sleeve 24 may be closed by a wooden plug, or by a cap to prevent entry of slag before the probe is extended, or an inert gas may be introduced between the probe and the jacket. Since the sampler maybe retracted within the cooled jacket immediately, a liquidus arrest temperature is readily available.

Title: Improvements in and relating to frequency modulation system
IPC: H03C3/40
Filed: 1943-04-19
Abstract: 562,432. Phase modulation. BRITISH THOMSON-HOUSTON CO., Ltd. April 19, 1943, No. 6244. Convention date, April 23, 1942. [Class 40 (v)] A phase modulation circuit is designed to give a linear relation between signal voltage and carrier phase over a wide range of signal amplitude. Carrier from a source 10 is fed to a balanced circuit 17 shunted by a resistance 19 and condenser 20 of such values that. the carrier phase produced at the junction 22 is in quadrature with the opposed carrier phases at the opposite ends of the circuit 17. The three phases are applied to the control grids of three valves 11, 12, 13, the outputs of which combine in the circuit 39 and are fed through frequency multipliers &c. 15 to an aerial 16. The amplification of the valves 11, 13 is controlled by signal voltages from a microphone 14 fed in phase opposition to outer control grids. The amplification of the quadrature valve 12 is controlled by the voltage across a resistance 83 which is connected as a load resistance to the full-wave rectifier 116 fed from a potentiometer 110 across the microphone circuit. The effect is that as the signal voltage rises in either sense and so increases the amplitude difference of the carriers fed through valves 11, 13, the quadrature voltage fed through the valve 12 is reduced, thereby rendering the phase change more nearly proportional to the signal voltage. The amount of the reduction of quadrature voltage is regulated by the slider 112, and the point at which the rectifier begins to operate is adjusted by the bias potentiometer 122.

A container closure comprises a capsule 6 with a skirt 8 adapted to fit the container neck 3, the capsule 6 having a base 12 with at least one eccentric orifice (13), Fig. 3 (not shown), and cap 7 with an internally threaded skirt 18 to engage threads on the container neck. The cap 7 has knives 19 on an annular sealing extension 16 which locate in the orifices. When the cap is initially removed the knives 19 cut out the base 12 around its weakened circumference. The centre annular skirt 17 prevents the cap 7 from being forced downward and the base 12 from being unintentionally fractured. The cap 7 also has a central bar 14 which passes through a central hole in the member 12 and forms a head so that, when fitted to the container the two parts 7 and 8 are joined. In this way the base 12 remains fixed to the bar 14 on opening. The skirt 18 has axial notches at its lower edge, the threads being formed on intermediate tongues (21), Fig. 2 (not shown).

Title: Improvements in or relating to apparatus for artificial respiration
IPC: A61M16/00
Filed: 1953-03-09
Abstract: 730,242. Artificial respiration. DRAGER, O. H. March 9, 1953 [March 7, 1952], No. 6496/53. Class 81 (2). Artificial respiration apparatus in which air is alternately forced and extracted from a pipe leading to the lung in dependence upon the pressure in the lung is characterised by the provision of an injector which on its suction and exhaust sides communicates with the outside air by way of an independent non-return valve in each case, the non-return valves being operated by a negative or positive pressure. Gas e.g. compressed air or oxygen is passed through an injector 1, the suction and exhaust sides of which communicate with a chamber 7 through valves 12, 3 respectively which are operated by a lever 8 connected to a diaphragm 11 in the wall of the chamber 7 so that when one valve is shut the other is open and vice versa. When the valve 3 on the exhaust side of the injector 1 is open, gas passes to. the chamber 7 and lungs 9 in communication with the chamber 7 to produce an inhalation. A non-return spring controlled valve 5 between the exhaust side of the injector 1 and the atmosphere closes and a similar valve 13 on the suction side of the injector 1 opens. This continues until a predetermined maximum pressure in the chamber 7 causes the diaphragm 11 in the wall of the chamber 7 to move outwardly to operate the lever 8 which closes the valve 3 and opens the valve 12 in communication with the suction side of the injector 1. The injector 1 then causes gas to be sucked out of the chamber 7 and the lungs 9 to produce an exhalation, the non-return valve 13 between the suction side of the injector 1 and the atmosphere to be closed and the non-return valve 5 between the exhaust side of the injector 1 and the atmosphere to be opened. This continues until a predetermined minimum pressure is obtained in the chamber 7 when the diaphragm 11 moves inwardly to operate the lever 8 so that the valve 12 is closed and valve 3 is opened to produce a further inhalation. The cycle of operations is repeated.

The plates 1, 2 embrace less than half of the roll 4 and each is provided with the usual flexible joints 6, the lower plate 2 moving away from the roll 4 under gravity and the upper plate 1 under the action of a counter-weight 7 when the hydraulic pressure is reduced. The chambers 8, 9 are separate and the pressures therein may differ. The cover 10 is hinged at 11 to facilitate changing the plates. In a modification, the hydraulic actuating means for each bed plate is located exterior of the roll chamber and comprises a diaphragm 11<1>, Fig. 2. in a chamber 12 and provided with cylindrical guides 13, 15 engaging sockets 14, 16. In a further modification, the plate box 18, Fig. 3, having a cylindrical guide 19 in a socket 20 is carried in a member 17 having supplementary guide surfaces 23, the diaphragm 21 and pressure chamber being arranged as shown.
