Abstract: 1,259,380. Hydraulic reciprocating pumps or motors; gaseous pressure engines. NUTRON CORP. May 14, 1969 [May 17, 1968], No. 24686/69. Headings F1A and F1M. A compressed gas or hydraulic motor or pump comprises a rotary cylinder block 42 mounted on a shaft 32 for rotation between end caps 10, 14, the caps being provided with inclined thrust rings 44, 46 each engaged by a plurality of ball pistons 66 slidable in axial cylinders in the block. Each cylinder contains two ball pistons 66, the space therebetween being connected by an inclined passage 88 to an individual axial bore 70, 72... 86 passing through the block 42. These bores communicate alternatively with arcuate manifolds 38, 40 in the surfaces of the caps 10, 14 confronting the ends of the rotary block 42. Reversible inlet 34 and outlet 36 extend through the cap 10 and connect with the manifolds 38, 40, respectively. The provision of the arcuate manifolds 38, 40 in the cap 14 balances the pressure forces acting on the block 42 due to the pressure in the manifolds 38, 40 in the cap 10. The inclination of the rings 44, 46 may be adjustable, The motor or pump may be made of nylon.

Abstract: 1290047 Radar NORTH AMERICAN ROCKWELL CORP 18 Sept 1970 [17 Nov 1969] 44683/70 Heading H4D To improve azimuth resolution in a scanning pulse ground mapping radar, using an antenna system having a lobe 12, Fig. 1, such that a target 11 gives rise to a plurality of range gated echoes I (t) , Fig. 5a, having an amplitude variation envelope W(T), Fig. 4, the response fed to a filter having an impulse response corresponding in shape and duration to said envelope. The responses (outputs) of the filter to the successive echoes I (t1) -I (t7)  are shown at 21-27 respectively in Figs. 5b-5h. A hold circuit summing all these outputs produces the curve 29, Fig. 5(i), which has a pronounced maximum 28 at time t 8  indicating the sweeping of the target by the trailing half power point of the lobe.

Abstract: 1304003 Sampling liquids IMPERIAL CHEMICAL INDUSTRIES Ltd 20 March 1970 [28 March 1969] 16455/69 Heading B8N [Also in Division B1] A liquid in pipe 10 (Fig. 3) is sampled by regulating the flow of a carrier liquid in line 9 at two points, one upstream and one downstream of the sample source, the rate of flow upstream of the source being regulated to be less than that at the point downstream of the source by an amount equal to the rate of sample inflow from line 10. The sample liquid is preferably degassed by tangential injection through entry part 2 of cylinder 1 (Fig. 1) when it falls in a thin continuous film down the inner surface of the cylinder to exit port 5 and thence to the sampling device. The pressure in the system is controlled by controlling the pressure at the gas exit port 3. The pumps 7, 8 may be diaphragm pumps, the diaphragms being driven by pulses from actuators 13, 14 under control of timer 15 so that the pulses are 180 degrees out of phase. There is reference to sampling an oxidation reaction mixture containing a catalyst which would precipitate in the absence of an oxygen atmosphere, and to sampling slurries.

Abstract: 1308426 Educational appliances; question and answer devices EPOCH CO Ltd 8 June 1971 19409/71 Heading G5G [Also in Division H1] An educational device comprises a board or card 24 bearing two sets of matchable indicia 26 and coded by notches with the way in which indicia are to be matched, a housing 12 for receiving said board and including a plurality of button operated switches 22 connected to an indicator such as a lamp 34 behind a window 16, the arrangement being such that the indicator is energized only when a pair of buttons corresponding to matching indicia are actuated. As shown, first contacts 36 of the left hand column of buttons are separately connected to segmented contacts 56 by conductors 58. Second contacts 42 of these buttons are connected in common to the lamp 34. First contacts 36<SP>1</SP> of the right hand column of buttons are separately connected to contact members 64 by conductors 70. Second contacts 42<SP>1</SP> of these buttons are connected in common to a battery 32. The leading edge of each board or card 24 is notched (Fig. 2, not shown) so that, as this edge is inserted into a slot 14 of the housing 12 (see Fig. 6), electrical contact between contacts 56 and 64 is selectively broken in such a way that energisation of the lamp 34 can only occur if buttons for matching indicia are actuated. Depression of a button 22 against resilience of a strip 44 (Fig. 7) causes a projection 48 to deflect the contact strip 42 through an aperture 40 in an insulator strip 38 so as to make contact with a contact 36. Several different boards 24 are provided, each with apertures (28) to fit over the buttons 22.

Title: Polymeric high performance composites
IPC: C08L33/00
Filed: 1969-10-02
Abstract: 1313749 Polymer/mica composites CANADIAN PATENTS & DEVELOPMENT Ltd 1 Oct 1970 [2 Oct 1969] 48547/69 Headings C3P and C3R A composite comprises a solid polymer and a mica reinforcing material, the mica being in the form of platelets, substantially all of which have an aspect ratio of at least 30, and comprising 10-75% by volume of the composite, the polymer embedding each platelet and the platelets being substantially coplanar or parallel. The platelets preferably have a diameter of 1-1000 microns and a thickness of at least 0À001 microns. Before incorporation the platelets may be surface treated with nitric acid or aqua regia, and the composite may also contain a metal oxide thickener such as MgO, CaO, BaO and ZnO, and coupling agent, known in the art. The polymer/platelet cohesion is also enhanced by using a polymer containing groups having an affinity for the mica surface, such as free carboxylic acid groups. Preferred polymers are derived from vinyl compounds, but other polymers such as thermosetting polyesters and polycarbonates may be used. Polyamides and epoxy resins are also mentioned. The composites are obtained by (a) providing segregated mica platelets of aspect ratio at least 30, (b) embedding them, in some way in the polymer, (c) causing them to align in the same direction and (d) rigidifying the polymer. Several methods are described : (1) the platelets may be carefully mixed (to avoid breakdown) with a liquid resin precursor such as a liquid unsaturated polyester/ styrene mixture; (2) they may be mixed with a resin latex and the solids coprecipitated; (3) the monomers of the polymer may be polymerized in the presence of the platelets; (4) the platelets may be mixed with a solution of the polymer, and the solvent evaporated, and (5) the platelets may be mixed with a molten polymer. In all methods, especially the fifth, the platelets are preferably pre-coated with polymer (e.g. by polymerization on their surface), to increase their strength. Alignment of the platelets in all the methods, is achieved by moulding with shear. Rolling into sheet form also aids alignment. In the examples: (1) and (2) mica is mixed with a styrene/acrylic acid copolymer latex and the mixture precipitated and the dry product moulded with shear; (3) the mica is mixed with a solution in methylene chloride, of a polycarbonate resin, the solvent evaporated, and the product moulded as in (1); (4) styrene and dimethylaminoethyl methacrylate are copolymerized in water in the presence of the mica, and the resulting crumbs moulded as before, and (5) styrene is polymerized as in (4).

The apertures are notched to prevent cross member rotation, and reinforced by welded blocks. Welded to the upper flanges of the cross members 14 (Fig. 3) and to the casting plate 11 are further I-shaped members 24 and cross bracing is provided by angled diagonal members 34. Two casting tables may be joined by bolts extending through a skirt 27 depending from the plate 11. The table may be mounted on vibrators, or vibrators be attached to mounting plates 33 on the cross members 14. Hot air, gas or water vapour is passed through ducts (not shown) under the plate 11, and through the girder apertures. Tubes 36 (Fig. 5) bolted to the mounting plates 33 are pivoted by pins 43 on support brackets 45, and the table is raised to a vertical position by a hoist engaging a stirrup 50 on further tubes 36. A prop 51 secures the table when hoisted. Each tube 36 supports a spigot 41 and apertured plate 40, those of adjacent tables being interengageable for stacking purposes. Concrete slabs and beams are cast on the plate 11 using shuttering (not shown).
