Abstract: 1412442 Plate heat exchangers UNION CARBIDE CORP 13 Oct 1972 [15 Oct 1971] 47238/72 Heading F4S A heat exchanger has a heat transfer wall formed (e.g. by pressing, stamping or rolling) to provide on said wall a unidirectional plurality of bubble-like projections each having distributed around its periphery a plurality of load bearing areas d which an assembly are in abutment with (and may be bonded to) similar areas of an adjacent wall; the wall and projections having the following dimensional relationship: (a) Ratio H/D of between 0À05 and 0À2; (b) Ratio D/d of between 3 and 10. (c) Dimension D of between 0À2 and 2À5 inches.; (d) Wall thickness of between 0À003 and 0À25 inches, where the dimensions D, d and H are as indicated in Figs. 1 and 3A. A method of calculating the shape of the bubbles to provide isostress contours (defined in the Specification) is described. The heat exchanger preferably comprises a stack of hollow-plate members 30. These may be formed each from a folded sheet (as shown) or from two sheets with either marginal spacers or with their edges seamed together. The heat exchanging fluids may be in parallel-flow or in cross-flowing relation; and the projections may be disposed in a square, diamond, or triangular formation. Alternative materials suggested for the heat transfer wall are metals (e.g. aluminium, copper, steel and titanium), metal alloys (e.g. brass), clad metals, plastics and plasticcoated metals. The projections 31 which through the stack may be in alignment, or relatively staggered (Fig. 5C) may protrude either externally of the hollow members (Figs. 6, 6A, 6B) or internally of the hollow members (as shown) in which case external support members 34 may be provided. The hollow members preferably extend between headers (10, Fig. 5). Fig. 5D shows a modification in which the plate members extend beyond the edge seam to form external fins 16 which may have turbulence-promoting slots or dimples therein. A modification only briefly described comprises the wall folded to form a cylindrical or spirally extending heat exchange element.

Abstract: 1,164,993. Harvesting peas. NATIONAL RESEARCH DEVELOPMENT CORP. 8 Feb., 1967 [9 Nov., 1965], No. 47399/65. Heading AlF. A pea-picking apparatus, movable along a plant-row, comprises bine-lifting means 3 which raise the pea-bine into an upright position, gripping means 4 which engage temporarily with the bine below the peabearing portion thereof and carry this portion rearwardly as the apparatus advances, and picking means 19, 20 disposed above the bine-gripping means to contact, and cause separation from the bine of, pods situated at progressively higher portions of the upper portion of the bine as the latter is carried rearwardly through the gripping means. The apparatus is mounted on a frame 1 secured laterally to a tractor (not shown) by links la and 1b and carried on a single ground-wheel 2. The lifting means comprise dividers flanking a rearwardlytapering passage leading to a nip between endless belts 4 carried on pairs of vertical rollers 5, 6, 7, the front and rear pairs 5, 6 being spaced apart and the intermediate rollers being spring-pressed inwardly to cause the belts to grip the bines. The picking means comprises a pair of conical rollers 19, 20 rotating inwardly and upwardly to provide a nip which admits the bines but rejects the pods which fall off on to an inclined surface 27 down which they roll on to a conveyer-band 29 leading to a bagging shoot 30. The rollers 19, 20 are both supported and driven from their rear ends only, and slope upwardly and rearwardly and also laterally so that progressively higher and higher bine-portions are stripped as the bine travels rearwardly. The belts travel rearwardly at the same speed as the forward speed of the apparatus and the bines are cut at ground-level by a reciprocating mower-bar 13, 14 of which the upper, knife, bar 14 is longitudinally reciprocated by a crank and pitman from gearing driven by the groundwheel 2 which also drives the belts and picking rollers. In modifications (not illustrated) the drive may be derived from a motor on the machine or from the tractor.

Abstract: 1333446 Durometers A ERNST 13 Oct 1971 [24 Nov 1970] 47714/71 Heading G1S A hardness tester comprises an outer casing 1, a shearing member 3 and a pin 5 abutting a control bar 4 of known shear. The pin 5 is frictionally held in position by a spring pressed ball 7. When the head 9 of the member 3 is struck heavily the indentor 6 penetrates a test surface and the pin 4 is sheared to apply a known force to the indentor. The excess impact force causes the collar section 10 of the member 3 to wedge firmly in the flared casing section 2 and avoid rebound of the shearing member. In Fig. 2 (not shown) the member 3 is not collared nor is the casing flared, instead a resilient damping ring is provided beneath the head 9. In other figures not shown a resilient ring is provided either beneath the foot end of the casing 1 or the casing is not provided and the ring is situated at the foot of the shearing member 3.

Patent GB-1444318-A (GB)
Title: Matrix testing apparatus
IPC: G01R31/50
Filed: 1974-11-07
Abstract: 1444318 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 7 Nov 1974 [15 Nov 1973] 48142/74 Heading H4K The individual crosspoints of an end-marked, multi-stage (PNPN diode) switching matrix are tested from permanent open- or shortcircuit condition by marking known endpoints and successively applying inhibition potentials to a particular stage of the network such that at any one time only one of the possible paths through this stage can be enabled. Certain end points are utilized only for test purposes and these are used at the start of a test for ascertaining the condition of diodes which will subsequently form parts of the path between normal endpoints (e.g. line circuits and junctors). Faults are determined on a statistical basis i.e. in an on-line network some crosspoints are in use for valid connections so that these must be eliminated from the test results. This is done by noting whether apparent failures to complete a path between two end points undergoing test exceed a notional value. The number of tests a particular diode undergoes varies in dependence on its position in the network but varies from a few units up to several hundred. For an on-line network using on-line computers up to 12 hours is required to fully test the network although this is reduced to ¢ hour if the network is off-line. The network and its mode of operation is fully described in Specification 1,415,762. For convenience its basic outline is summarized with reference to Fig. 3. The inlets are grouped in batches of 160 on primary/secondary units LS which concentrate the inlets to 45 outlets. These are distributed over 45 tertiary matrices which are arranged into 5 sections TS each of 3 blocks TBD each of three 10 Î 10 matrices SW. Each section has 90 outlets linked to a particular quaternary section QS. The latter each consists of 6 blocks BLK containing five 3 x 9 matrices. Any inlet/outlet connection can thus extend over one of 9 possible paths, these paths passing through adjacent matrices of a single tertiary section. The inhibit markings from the test apparatus (Fig. 6, not shown) are applied to control apparatus (Fig. 5, not shown) of the tertiary stage such as to enable only one matrix in each section at a time. (Only one section will in fact respond since the QH end marking can only reach one TS section). By effecting every combination of PH/QH markings and checking the 9 possible paths per such marking every crosspoint is subjected to test. The Specification contains instructions on how the test procedure identifies particular faulty crosspoints. The test is effected by a duplicated computer which provides its end-marking and inhibit instructions to the test apparatus which serves as an interface for translating and relaying these instructions to the network and submitting test results and time out alarms to a print-out.

Alternatively a plurality of wire rings (13), Fig. 3 (not shown), may be used and each ring (13) is located in a groove (12) formed in the roller surface. Cores of different diameters may be accommodated in the groove 4 by varying the diameter of the wire 8 or of the rings (13). The roller may be hollow and the groove 4 connected to a vacuum source via the hollow, thereby speeding the entry of the cores into the groove and removing dirt from it. The cores are discharged from the groove by compressed air.
