Title: Calcination of kaolin in the presence of hydrochloric acid - gives increased whiteness esp. when rapidly heated
IPC: C04B33/10
Filed: 1973-12-04
Abstract: A calcined kaolin of high whiteness value is obtd. by calcining kaolin in the presence of HCl at 900-1200 degrees C (1050-1100 degrees C). The kaolin is mixed before calcining with liq. HCl or a chlorinated solid which releases gaseous HCl during calcination, e.g. an alkali(ne earth)chloride. The HCl is used in amt. 1-2 wt % of the wt. of dry kaolin being treated. The mixt. is pref. submitted to a sharp thermal shock to heat it rapidly to the calcination temp. and after treatment is cooled similarly. The kaolin is used as pigments in rubber, elastomers plastics and paints. The HCl removes ferric oxide normally occurring in the kaolin, by reaction forming volatile ferric chloride and moisture. The thermal shock causes the gas to be evolved rapidly at the calcination temp. The rapid heating minimises the dissociation of HCl.

Title: Mechanical calculator for decibel quantities - with hand operated slide rule for summation calculations
Inventor: BARBARA JEAN-JACQUES
IPC: G06G1/00
Filed: 1974-11-19
Abstract: The calculator consists of a flat rectangular plaque (15) on which two straight lines (A, B) and a curved line (C) are drawn. Two supports mounted on a base plate (10) allow the plaque (15) to be slid in only one direction. The line A is parallel to this direction. A ruler (20) with uniform graduations is mounted in the supports so that it can be slid along its length and in a direction perpendicular to the line A. To use the calculator to add two decibel quantities, the ruler (20) is slid across the plaque (5) until the ruler graduation corresponding to the value of the first quantity coincides with the line A. The plaque (5) is then slid until the ruler graduation corresponding to the second quantity coincides with the line B. The sum of the two quantities in decibels is then read from the ruler where it coincides with the line C.

Title: Piston shoe of a radial piston engine - has openings for improving flow, reducing losses and preventing overheating
IPC: F16C32/06
Filed: 1975-01-13
Abstract: The piston shoe of a radial piston engine is used for the reciprocating piston actuated by a rotor and this piston slides within a radial cylinder. The piston shoes have radial guiding surfaces, and are used in hydraulic or pneumatic compressor pumps, motors and drives. The performance of the engine is improved by correcting small errors in the hydrostatic support of the piston shoe, which ensures that efficiency is maintained at a very high level also at high power outputs, and losses are reduced so that the unit is not overheated. The sealing face of the pressurised fluid pockets (2) have openings in the bearing support faces of guides (6) of the piston shoes (7). These openings are arranged in the sliding faces and form openings in the piston shoe and parts.

Title: Automatic gear box for road vehicles - uses control pressure which is increased at low speed to achieve rapid gear change (SW111076)
IPC: F16H61/02
Filed: 1975-04-10
Abstract: The automatic gear box has a valve which controls the actuation of the clutches and brakes of the change speed gear. The gear engaged depends on the pressure of the oil supplied to this valve. This pressure is controlled by the pressure reducing valves (40 and 340). The pressure from these valves is controlled by the accelerator pedal whic actuates the cam (N). To provide a more rapid gear change at low engine speed, a second valve is fitted in the line (222) and connected to a pressure damper in such a way that the pressure rises more rapidly, when the accelerator pedal is depressed at low engine speed.
