Title: Chocks
Inventor: PENTINGA KORNELIS JURRIEN
IPC: B60P3/077
Filed: 1968-10-25
Abstract: 1,215,759. Chocks. K. J. PENTINGA. 25 Oct., 1968 [27 Oct., 1967], No. 50845/68. Heading F2E. In a chock a base-plate 11 is provided with anchoring ridges 2, 12 beneath the base-plate and upright plates 3, provided at two of the corners of the base-plate, are inclined towards each other at an angle of 25 degrees to merge with a supporting plate 6 inclined at an angle of 80 degrees to the base-plate substantially mid-way between the ends of the base-plate. The chock may be used in two positions; the first position where the chock is placed with the plates 3 under a wheel of a vehicle so that during transportation of the vehicle a retarding or accelerating force of the transported vehicle is absorbed on the top edges 4 and together with part of the vehicle's own weight a component of such a force presses the ridges 2 and 12 firmly into the platform of the supporting surface; a second position wherein the chock is placed at the side of the wheel so that the supporting plate 6 abuts the side of the wheel and the vehicle's own weight presses the ridges into the supporting surface to keep the chock firm. The ridges 2 provided beneath the base-plate and beneath the surfaces 4 and 6 are closer together than the ridges 12 beneath the remainder of the base-plate. Additional ridges 13 are provided at right angles to the ridges 2, 12 and are shorter in length to provide additional gripping between the base-plate and the supporting surface.

Title: Method of moulding an article having a foamed body and a bonded overlay
IPC: B29C35/08
Filed: 1977-12-09
Abstract: A closed-cell, thermoplastic foam is first used to form a blank. The latter is heated until its surface fuses and its core zone is plastically deformable and is then, together with a flat structure to be laminated on, introduced into a hollow mould. During the closing movement of the hollow mould and subsequently thereto, the blank adheres on its surface to the flat structure, the latter being pressed against the inner wall of the hollow mould to form the final shape of the workpiece. The process permits short cycle times and is flexible by the fact that the nature and relative size of the laminated-on flat structure can be to a large extent freely chosen.

Title: Process and an apparatus for the continuous production of flat or longitudinally profiled sheets from synthetic resin
IPC: B29C53/26
Filed: 1968-10-29
Abstract: 1,216,259. Forming elongated articles. MUANYAGIPARI KUTATO INTEZET. 29 Oct., 1968 [3 Nov., 1967], No. 51299/68. Heading B5A. In a method of making elongated articles by drawing a soft sheet through a passage in which it is shaped and hardened, friction is greatly reduced by introducing a gaseous medium between the walls of the passage and the sheet. Thermoplastic and thermosetting resins with or without reinforcing fleeces or covering foils, may be shaped in this manner the gaseous medium being cooled to effect the hardening in the former case and hot to effect setting in the latter case. Where a resin impregnated fleece is being used a tough layer of resin is formed on the outer surfaces of the furnished article which layer precludes deterioration of the fibres of the fleece by the atmosphere. In the embodiment illustrated in the Figure, a corrugated sheet 1 is formed in a slightly oversized passage defined by upper and lower elements 3 and 2, the layers of gas 6 being formed by air introduced through bores in the element walls and leaving via the edges of the passage. The spacing of the bores may be arranged so that the air pressure is greater at the troughs than at the ridges, this concentrating any slight flow under gravity of the resin from the ridges to the troughs and thus maintaining a product of uniform thickness.

Title: Process for regenerating absorbing solution used for exhaust gas purification
IPC: B01D53/60
Filed: 1975-12-15
Abstract: 1491386 Exhaust gas purification; regeneration of absorption liquor CHISSO CORP and CHISSO ENG CO Ltd 15 Dec 1975 [28 Dec 1974 (2)] 51304/75 Heading ClA In a process of removing SO2 and NO 4  from exhaust gases by absorption in a solution containing an iron chelate complex salt and a sulphate, the spent absorption solution is removed from the absorption zone, heated to at least 80‹ C. at pH 3À0 or less, and the regenerated solution is recirculated to the absorption zone. The heat treatment, e.g. 1-10 hours at 120-140‹ C., decomposes dithionate to form SO2, which is redissolved in the solution, and sulphate which is removed. The pH may be maintained at 0-10 by adding H 2 SO 4 , and the solution may be concentrated before regeneration. In one embodiment, the solution is cooled to 0‹ C. at pH 2À2 to precipitate chelate complex, then the pH is further reduced to 0À8 (at 0‹ C.) to precipitate chelating agent, before regeneration.
Patent GB-513823-A (GB)
Abstract: 513,823. Calculating-apparatus. PIOVANO, G. Dec. 20, 1937, No. 35257. Void. Convention date, Dec. 19, 1936. [Class 106 (i)] The Specification, which is not clear, broadly describes a machine for multiplying by repeated addition. For each denomination a key H on depression separates a pair of toothed arcs S', S<SP>2</SP> by the amount of the key, a spring p pulls a rack when released by a key P to position the carriage V with the differentially set arcs to appropriate position opposite the product register B, each partial product being formed by turning' the crank m the required number of times, thus building up the multiplier on the register b. Each denomination in B is thus operated through an amount .9 + number set at each turn of the crank, the extra 9 teeth ensuring the action of the transfer. When a 9 is passed a lever y is thrown over to bring a higher gear into reach of the appropriate one of a set of staggered pins K on a shaft G. The keyboard action is obscure.

Title: Memory circuit using storage capacitance
Inventor: BOOHER ROBERT KENNETH
IPC: G11C11/402
Filed: 1969-10-20
Abstract: 1,243,589. Digital memory circuits. NORTH AMERICAN ROCKWELL CORP. 20 Oct., 1969 [7 Jan., 1969], No. 51407/69. Heading H3T. A storage capacitor 4 stores a binary digit such as a negative level from F.E.T. 3 during a first time period, and during a subsequent period it controls a device, such as a F.E.T. 9 which receives a negative read signal from 19 and which is connected, for example through a capacitor 5 and impedance 8, to supply a boosting charge to the storage capacitor 4. This boost is to compensate for leakage. When an information line 2 is selected by an address circuit (20-25, Fig. 3, not shown) to receive from a data input (34) a binary signal, a write circuit 51 turns on F.E.T. 3 to charge capacitor 4 to a negative level or to earth. If a negative voltage is stored, then F.E.T. 9 is conductive and when a negative read pulse appeats from 19, this pulse is applied to capacitor 5 which transmits it through F.E.T. 8 to the storage capacitor 4. A further F.E.T. 7 may be controlled by the voltage on C4 so that the upper electrode of C5 is already charged negatively from -V, and so that when the read, pulse appears from 19 an enhanced charging of capacitor 4 is achieved to turn on F.E.T. 9 even more. The voltage drop across F.E.T. 9 is thus reduced. The negative read pulse passing through F.E.T. 9 also passes through a read/ reset F.E.T. 6 to the output line 2. Prior to the read pulse at 19, however, the charge on inherent line capacitance 16 due to the previous negative data input must be discharged. This is done by F.E.T. 6 being turned on while the read output 19 is still at earth and is non- nected through the now conductive F.E.T. 9 to the F.E.T. 6. If a zero voltage is stored, then capacitance 16 is at earth potential, and remains so through the read cycle since F.E.T 9 does not conduct. A reset F.E.T.(44) discharges the output line of the system (Fig. 3) using a plurality of the Fig. 1 circuits (27, 28, 29, 30).

Abstract: 1,118,918. Processing fish. NORDISCHER MASCHINENBAU RUD. BAADER. 3 Dec, 1965, No. 51414/65. Heading A2U. In a method and apparatus for processing fish, such as cod, pollock, whiting and Norwegian haddock (redfish or rosefish), each fish 6, e.g. supported belly upwards and horizontally on a table 8, is impaled on a spear 1, between the rearmost of its gill arches 14 and its collar-bones 12, and below its gullet 10. The fish, e.g. after having been removed from the table and swivelled into a vertical, suspended position, is moved along the spear by a transverse member 3 of an endless, travelling chain conveyer (shown in chain-dotted outline in Fig. 1) to meet a knife 4, which passes transversely through the fish, just above the spear. The knife 4 is then moved away from the gullet, e.g. swung upwardly about a pivot, to cut through the skin 16, between the rearmost gill arch and the collar-bones 12, and sever the lower maxilla 13 from the collar-bones. The knife 4 emerges from the fish at the isthmus 17. The fish is then moved to a rotating disc cutter 5, which passes through the cut already made and makes a cut through the gullet 10 towards the spinal column 11. The fish is finally removed from the spear by the conveyer. A guide 2 may contact the end of the fish during its movement towards and past the knife 4.

Abstract: 1324499 Digital weighing apparatus METTLER INSTRUMENTE AG 15 Nov 1971 [26 April 1971 30 Aug 1971] 52885/71 Heading G4H In a digital weighing apparatus the weight on a scale pan 9 moves a magnet 3, supported by springs 8 inside a coil 6. Annular capacitors 11 provide via units 12 and 13 a magnet-position signal which is compared with a sawtooth waveform in modulator circuit 14. For each cycle of the sawtooth, modulator 14 generates a pulse whose duration is proportional to the position signal and which (a) gates a current from supply 10 via switch 17 to the coil to momentarily restore the magnet to its zero position and (b) opens gates 19 to feed clock pulses from oscillator 15 to a counter 20. Counter 20 thereby receives for each cycle of the sawtooth a number of pulses proportional to the weight to be measured. A counter controller 26, fed by oscillator 15 via dividers 16 and 25, reads out counter 20 to a store 21 every so many cycles of the sawtooth, thereby providing an average measurement of the weight for printing at 23 or display at 22. The weight of an initially weighed tare may be stored in store 27 and means to preset the counter negatively at the beginning of each of its counting cycles, only the true weight or anything added to the tare being displayed or printed. The tare facility, which is brought into operation by switch 26a, may be used to weigh a succession of items added to the scale pan, with indication of each net excess. The resolution of the apparatus may be varied by choosing one of a number of frequencies of the oscillator 15 in conjunction with different counting ranges of counter 20 (Fig. 2, not shown). The apparatus may be calibrated by adjustment of the value of current from the constant current supply generator 10, the frequency of oscillator 15, or the reduction ratios of the frequency dividers 16 and 25. Rapid fluctuations of the display are avoided by not displaying the least significant digit from the counter 20.
