Abstract: 1,265,026. Treating textiles with liquids. M. MASUDA. 28 May, 1969 [29 May, 1968], No. 27068/69. Heading D1L. An endless length of textile material is passed in sinuous form through a liquid containing U-shaped passage 3 which is wider on the outlet side 3b than on the inlet side 3a and which is formed by an outer container 1 and an inner member 2 having a plurality of liquid inlets 12, outlets 13 and supply channels 11 and a pump 14 for circulation of liquid through the passage 3. The width of the outlet side may be 1.5-2 times that of the inlet side. Folding may be effected by feeding from a reel 4 onto a reciprocating device 9, on a J- shaped device, Fig. 3 or 4, not shown, or by folding on the upper surface of the member 2, Fig. 5, not shown. Reel 4 may be oval, Fig. 6, not shown. For treatment with liquid at high temperature and pressure a closed apparatus may be employed, Fig. 7, not shown.

Abstract: 1,266,961. Recovering oils and/or fats. CAVSOL Ltd. 3 May, 1969, No. 22688/69. Heading C5C. [Also in Division C1] A process for recovering fats or oils from sewage comprises concentrating a raw sewage sludge or an activated sludge by reducing the water content thereof (e.g. by settling and centrifuging), subjecting the concentrated sludge to a counter-current extraction with a hydrophilic organic solvent(s) in successive stages and concentrating the solid material in a small proportion of solvent/water mixture at the conclusion of each stage (e.g. by centrifugal decanting) and passing the solids to the subsequent stage, and removing any solvent present from the solids from the final stage to yield dry nitrogenous material. Distillation of the solvent/water filtrate and centrifugation of the residue enables fats and oils to be recovered. Suitable organic solvents are acetone, methyl alcohol, ethyl alcohol, isopropyl alcohol and ethyl alcohol/ethyl acetate/isopropyl ether.

Abstract: 1290833 Gauging machines; photo-electric instrument reading BENDIX CORP 13 Feb 1970 [13 Feb 1969] 7130/70 Headings G1A and G1M A hemi-spherical workpiece 23, Fig.1, is contacted by internal and external measuring probes 18 both of which may be rotated in anti-friction bearings about a horizontal axis 15 and in a vertical plane. Each probe 18 moves axially in a housing and is provided with an actuating piston 52, Fig.4, having a face 55 which is acted upon by air under positive or negative pressure, taking atmospheric pressure as zero. This air is supplied from an apparatus or supply system 50 and provides a force counteracting the weight of each probe as it swings through its measuring arc in the vertical plane. The force so produced results from the generation of a fluid pressure signal which is a function of the sine of the included angle between the axis 51 and a reference plane, a horizontal plane in Fig.4, and is used to control and keep constant the contact force exerted on the workpiece by the probe. The apparatus 50 comprises several air-pressure sources, a vacuum source, and pressure regulators and valves controlling air lines 70, 75, 85 and 110 and through them the inward or outward gauging movements of the probes. In operation, the probes are swung in an arc as shown in Fig.4, by electric motors and gears, and the weights of the probes are counterbalanced by the positive or negative pressures respectively acting on the piston surfaces 55. These pressures are determined by rods 65, the axes of which are parallel to the axes of their respective probes, Fig. 3, and the rods are slidable in air bearings 83 against the action of springs 96, 97. Each rod as it moves with the varying sweep of its probe obturates the opening of a control air jet 64 which operates relays and valves in other pneumatic circuits supplying each of the cylinders 53 with air or vacuum. Thus, in Fig. 5 (not shown) the upper probe at its zenith position has its weight partly supported by air under pressure in the cylinder 53 below the piston 52, whilst the lower probe in a similar position is supported against the workpiece by vacuum above its piston 52, these positive and negative pressures being arranged to vary as the sine of the angle of probe inclination. The worktable and workpiece may be turned about their vertical axis by means of a motor 45 and gears 46, 47, or by hand. In Fig.4, electro-optical means are provided to measure the movements of the probes. For example, reflective surfaces 115 on pistons 52 and reflective surfaces 117 co-operate to reflect light from a source 122 which has been passed through a 50% reflective diagonal beamsplitting surface 120. These reflected and spaced rays 123, 124, produce an interference pattern which is detected by photo-electric cells 121, and these cells provide electric signals to a device 131 which converts them to output signals corresponding to dimensional measurements of the workpiece which are displayed on a device 132.

Abstract: 1303833 Thermoelectric devices UNITED KINGDOM ATOMIC ENERGY AUTHORITY 19 April 1971 [30 Jan 1970] 4729/70 Heading H1K A connection is applied to a thermoelectric unit by securing a conductive member to one side face of the unit with an interposed insulating layer, one end of the member being flush with an end face of the unit, and forming a conductive bridge from the end of the member to the end of one of the elements of the unit. As shown, Fig. 1, a thermoelectric generator for a cardiac pacemaker comprises a Pu 238 radioactive heat source 22 enclosed in a steel can 23 bonded to one face of a thermoelectric unit 15 the opposite end of which is adhesively secured to a metal disc 16 which forms a heat sink. The disc is secured in a stainless steel housing 12 which is closed by an alumina plug 21 through which extend leads 17, 18 connected to the thermoelectric unit 15. The other end of the housing 12 is provided with a bore so that the housing can be evacuated or filled with an inert gas and then sealed by welding a plug 13 into the bore. The thermoelectric unit is produced by forming blocks of N- and P-type Bi 2 Te 3  by powder pressing, slicing the blocks into rectangular plates, Fig. 2 (not shown), assembling alternate N- and P-type plates with interposed layers (28) of cellular material such as cigarette paper impregnated with epoxy resin and allowing the assembly to set under pressure so that the spacing of the plates is determined by the thickness of the cellular material, Fig. 4 (not shown). The resulting block is sliced transversely to the plates to form a set of further plates each containing a plurality of alternate N- and P-type columnar elements; alternate plates are reversed and the plates are then reassembled with interposed layers 36 of epoxyresin-impregnated cigarette paper to form a block having alternate P- and N-type squaresection columns in each of two perpendicular directions. As shown in the underside plan view of Fig. 7, strips 37, 38 of Ni are secured to one face of the block with interposed insulating layers, the ends of the blocks are lapped flat and are photo-masked and Au is vacuum-deposited to form bridges 39 between adjacent pairs of elements, two of the bridges extending on to the ends of the Ni strip to which the external loads are secured. The grain size of the Bi 2 Te 3  is selected to be significantly less than the crosssection of the elements.

A part 4, which may be part of a machine tool, is moved by a pneumatic piston and cylinder 1, 2. Coupled to the part 4 is the piston rod 20 of hydraulic piston 21 so that movement of the part 4 is controlled by regulating the flow of fluid from one end of the cylinder 22 to the other end via the external circuit 23. Excessive pressure difference across the piston 21 is prevented by the external circuit path 41, 45 that include two resiliently biased one-way valves 38, 39 and which connect with a reservoir supply means 36. During a fast initial movement of piston 21 the drop in pressure on one side of the piston allows fluid from reservoir 36 to overcome one-way valve 38 or 39 and enter the cylinder. During a normal slower movement the fluid is transferred through the external circuit via needle valve 30, 31, 32. Valves 13, 14, 24 and 25 are solenoid operated to close off part of path 23 and direct fluid through the needle valves 30, 31, 32 to produce a slow movement of part 4. A solenoid also controls a valve 33 to select series or parallel arrangements of the needle valves. The solenoids are energized by the part 4 actuating switches at the ends of its travel to first slow it down and then stop it. A manual override solenoid 40 is provided.
