Abstract: A one piece wheel rim for a pneumatic tyre in which one tyre retaining flange has a reduced height portion (9) having a length of .25 to .5 times the bead seat circumference and the reduced height being such that the flange height, measured from the heel point (HP) is in the range of 0.15 to 0.6 times the height of the remainder of the flange to allow tyre fitting removal 
     The assembly provides a wheel rim having much increased brake space inside the wheel rim because it is not ncessary to have the conventional tyre fitting well and a fitting well of very much reduced, or indeed in some cases zero depth, may be used.

Abstract: A slurry stirrer, e.g. for use with agricultural waste slurry, comprises a rotatable shaft, which is preferably tubular, having a first end adapted for linkage to a source of rotary power and a second end adapted for attachment of an impeller, the shaft being rotatably mounted only towards the first end thereof in a fixed housing. With this arrangement, the second end of the shaft with impeller attached may be lowered and raised into and out of the slurry whilst avoiding bringing any bearings into contact with the slurry. Impellers are provided with two or more sets of impeller blades which tends to decrease the occurrence of cavitation in the stirred slurry.

Abstract: Provided is a modulator having two amplifying stages for supplying high-voltage pulses to the primary winding of a transformer connected to a microwave transmitter tube. The first stage uses field-effect transistors connected in a common source ccnfiguration to amplify input pulses to drive the second stage, which uses field-effect transistors connected in a common gate configuration to drive the transformer. The circuit configuration provides a large voltage swing across the transformer primary and a short transistor switching time.

Abstract: Aromatic hydrocarbons present in a hydrocarbon feed stream containing a mixture of aromatic hydrocarbons and non-aromatic saturated organic components are separated from said hydrocarbon feed stream by selective permeation of the aromatic hydrocarbon through a regenerated cellulose or cellulose acetate membrane which has been impregnated with polyethylene glycol. The thus treated membrane possesses high selectivity for aromatic hydrocarbons at a high flux. The amount and type of polyethylene glycol impregnated into the membrane is carefully controlled in order to achieve high aromatic selectivity and high flux.

Date Oct. 6, 1988.A process and arrangement for evaluating a measurable analog electronic quantity based on the principle of the timekeeping mechanism, in which the measurable analog quantity is digitalized by counting integration processes. To exploit the simplicity and precision of the timekeeping mechanism principle also far fast and precise digital data conversion units, a deviation coding phase (AV) is inserted between the timekeeping mechanism periods (T), in which post-adjustment of the timekeeping mechanism timing ratio is possible with rapid digital circuits even in the event of abrupt fluctuations of the quantity to be measured. The invention is generally applicable for highly precise and rapid digital data conversion of analog quantities, and is especially advantageous in high-precision measuring instruments with measuring sensors in bridge circuits, for example in weighing cells based on the DMS principle in electronic balances.

Title: Exterior antimigration refinements for self-cleaning indwelling therapeutic articles.
Inventor: GREENFELD ALBERT R
IPC: A61M27/00

Abstract: External grooving on a catheter traps microorganisms nurtured by mucus in a patient's body. The grooving also traps contaminating debris, originating outside the body, that migrates into the body along the catheter exterior. Energy, which may be a propagating vibration or electrical energy or a radioactive material, is carried to the groove (or grooves), from a source outside the body. This function is performed by a fiber embedded or held in the catheter, or by a liquid column (e.g., in an annular lumen) in the catheter, or in other ways. The energy disables microorganisms and disintegrates debris trapped at the groove. The groove depth, interface geometry, and in the case of vibrational energy the vibration frequency too, are selected to minimize projection of energy into the patient's tissues. Suction may be applied as through an auxiliary lumen (or, in some drain catheters, intermittently through the primary drain lumen itself), to remove resulting detritus at the grooving. Circumferential grooves may be used to impede migration longitudinally, longitudinal grooves to deter formation of continuous circumferential sheets of contaminants, or spiral grooves to lengthen the migration path along the catheter-or combinations of these forms.

Abstract: Disclosed is a gas injection technique of injecting an inert gas (e.g., nitrogen gas) into a molten resin in a cavity, wherein the strokes of reciprocation of a piston (2) in the compression cylinder (1) are used in a series mode, to perform a two-­stage compression within the same cylinder, thereby providing a high-pressure gas. Also disclosed is a method wherein during gas injection a relationship or pattern of the amount of movement of the piston with the speed of movement of the piston is established to provide optimum control of the relationship between the pressure generated and piston stroke, and quantity of gas injected. The injecting gas pressure can be detected, to control a hold pressure, or the relationship between a piston stroke and generated pressure, so as to obtain optimal injecting pressure during the injection molding operation. 
     Also disclosed is a novel gas injection apparatus. The apparatus comprises a compression cylinder (1) with a piston (2) wherein the volumes of the two chambers (4, 5) on both sides of the piston are of such a compression ratio to provide the first compression, pipe lines (10, 11) communicating the two chambers with each other through a check valve (7), a gas supplying conduit pipe (12) connected upstream of the check valve (7), and a conduit pipe (13) connecting the chamber located downstream of the check valve to the cavity, wherein the piston (2) is reciprocated to perform two-stage compression to provide a high pressure gas as required. The piston can be driven by an electric motor, and the torque of the electric motor transmitted through a power transmitting device comprising feed nuts and screws.
