Title: Welding machine with fixed upper jaw - for heat sealing polyethylene bags and sachets
IPC: B65B51/14
Filed: 1973-04-05
Abstract: Welding machine, particularly for heat-sealing polythene bags and sachets, of the known type having two horizontal superimposed jaws at least one of which is provided with a heating element and which can be clamped or spaced apart, the novel feature of the machine being that the upper jaw is fixed and the lower mobile jaw is normally maintained in contact with the fixed upper jaw by means of a spring and is integral with an parallel to a bar permitting the operator to space it from the fixed upper jaw while extending the sachet to be welded. The machine is designed to be operated on a table or bench without fixing and does not require a foot pedal, so that it is more compact and easier to use than those currently in use.

Title: Selectively separating esp drying gas mixts - selected constituents permeate from higher side of membrane
IPC: C02F1/44
Filed: 1973-05-29
Abstract: Gas mixts. or other fluid mixts. are selectively separated, in particular gas or air is dried, by passing the mixture through a number of generally parallel tubes of semi-permeable, esp. polymer material, through the walls of which the selected constituents, esp. water, permeate; the bundle of tubes is contained in an outer sleeve through which there passes, in contraflow to the mixture, a dry or reflux fluid, esp. a bled proportion of the discharge from the downstream end of the tube bundle; this reflux mixture is pref. at a considerably lower pressure than the feed mixture thus promoting the permeation of the constituents through the membrane walls. Pref., the downstream end of the appts. (relative to the flow in the tube bundle) is cooled by an external jacket.

Title: Determining drug-induced bilirubin release - by differential spectrometric determination of free or protein-bound bilirubin
IPC: G01N21/77
Filed: 1974-01-16
Abstract: A procedure for determining the relative ability of chemical agents (e.g. drugs) to release protein-bound bilirubin (I) comprises (a) measurement of the max absorption of (I) and/or free bilirubin in a plasma sample contg. a known proportion of bilirubin and protein; (b) addn. of various known amts of the chemical agents to aliquots of the same plasma sample (c) measurement of the decrease in the max absorption of (I) and/or the increase in the max. absorption of free bilirubin after each addn; (d) plotting of the inverse of the molar concn. of each chemical agent against the inverse of the increase or decrease in max. absorption or plotting the molar concn. of the chemical agent directly against the max. absorption increase or decrease; and (e) comparing the curves obtd. for each chemical agent. The method can be used to assess the bilirubin-release capability of various drugs in a particular patient's plasma so that a drug can be chosen which will give least bilirubin release and will therefore be less likely to give rise to potentially harmful hyperbilirubinaemia.
Patent FR-2259994-A1 (FR)
Title: Fuel economiser for vehicle engine - has water vessel with immersed vent coil projecting water into heater
IPC: F02M25/022
Filed: 1974-02-01
Abstract: A jet of air emulsified with water is heated in order to accelerate the combustible gas by partly releasing hydrogen and oxygen while retaining the ability to moisten the mixture, thus combining fuel economy with improved efficiency and reduction of atmospheric pollution. A vessel is connected directly to the inlet pipe and contains water in which a coil connected to atmosphere is immersed. This projects the emulsified water into a heater vaporising the mixture with partial decomposition into oxygen and hydrogen in the intake pipe. The sealed vessel can have a cover on which is mounted the nozzle connecting the coil to atmosphere, this nozzle being in the form of a needle valve controlling the air flow.

Title: Heating tapes incorporating wires individually covered - with organo-silicone insulation to inhibit permeation by moisture
Inventor: FONAREV Z I
IPC: F16L53/38
Filed: 1974-07-05
Abstract: Heating tape contg. heating elements comprises an array of electrical resistance mixes each surrounded by individual layers of insulation material and braided sheating, within the layers of insulation and sheating material used to hold the individual elements together. The insulating material on the individual elements is a heat stable material such as an organo-silicone rubber or resin.

Title: Agricultural machine for harvesting fruit - has contact belts moving at speed related to machine speed, and vibrator
Inventor: RAYNAUD PAUL
IPC: A01D46/26
Filed: 1974-08-09
Abstract: The machine is hinged on a self-propelled straddling vehicle by means of supports equidistant from the vehicle frame. The harvesting part of the machine consists of a horizontal cross member and two vertical arms each bearing at the lower part a belt assembly which together form large jaws. The contact belts run on rollers and are driven by hydraulic motors in a direction opposite to that in which the machine moves and at a speed related to the speed of the tractor. A vibrator bears a component on which is fitted a slide. As the machine moves along straddling the rows of fruit trees, the belts pass through the contact belts, which transmit the vibration from the vibrators to the plant, shaking the fruit off the tree.

Title: Deposition of hetero-epitaxial layers from liq. phase - rough surface on substrate bridges difference in lattice spacings
IPC: H01L21/208
Filed: 1974-08-20
Abstract: The deposition of an epitaxial layer (I) on the surface of a monocrystalline substrate of different compsn. to (I), where, prior to deposition, the substrate is subjected to a surface roughening treatment consisting pref. of lapping or etching. The roughening treatment pref. results in an average surface roughness of 0.3-2 mu, esp. 0.5-1 mu. This technique is advantageous where there is a difference in lattice constant (spacing) on gallium arsenide, or of gallium arsenide or gallium aluminium-arsenide onto gallium phosphide; the rough surface helps to bridge the distance in lattice spacing so a good epitaxial layer can be produced at low temp. with a small grain size.

Title: Prestressed concrete pipe end anchorage - has asymmetric T-section formed by three parts
IPC: F16L9/08
Filed: 1974-12-05
Abstract: The end anchorage of a prestressed concrete pipe has a steel ferrule (1) and a flange (2) which react the tensile load in a reinforcing rod (4). An extension (3) is welded to the ferrule and has internal corrugations which assist in transferring the prestressing loads into concrete shells. The ferrule projects radially outside the extension so that, during casting, it bears on the mould shell (M) via a flexible abutment (B). To construct the pipe the mould is fitted with the pipe ends, abutments and reinforcement rods and the latter are tensioned by an attachment (A) and nuts (5). When loaded, the concrete is cast and, when set, the abutments are removed, removal being assisted by their tapered form. Removal of the abutments puts the concrete in compression.
