Title: Improvements in or relating to trawling gear
IPC: A01K73/02
Filed: 1947-09-18
Abstract: 633,028. Fishing. BURNEY, Sir C. D. Sept. 18, 1947, No. 25469. [Class 48] A trawl net or a set of side by side nets 3, 3 is towed from a vessel by a main cable 1 attached to the centre of the head rope 7 and branch cables 4, to which are attached sheering devices, and which run from a point on the main cable between the vessel and the net to the sides of the head rope. Cables 9, 13, provided with sinkers 14, connect the main and branch cables to the foot rope 8. Wheels having their planes of rotation parallel to the direction of motion of the net are interposed in the foot rope. Wire reinforcement of the cod ends 25 is connected to the towing points of the net. Floats counteract the weight of the reinforcement and allow the cod ends to stream at a height equal to half the depth of the net mouth. The sheering devices 16 are in accordance with Specification 632,877, and are connected to the cables 4 at or in front of their junction with the cables 13. In a modification the sheering devices are dispensed with and normal otters are inserted in the cables 13. In a further modification the nets 3, 3 are spaced apart. According to the Provisional Specification the belly of the net has an area consisting of resilient longitudinal members which permits escape of stones and debris caught up in the net.

Title: A filter assembly
IPC: B01D35/153
Filed: 1970-05-27
Abstract: 1283814 Filters EVERPURE Inc 27 May 1970 [6 June 1969] 25487/70 Heading BID Liquid, e.g. water in a beverage vending machine, is filtered by a filter assembly comprising a filter, e.g. a folded bag filter 74, in a pressure vessel 59 having a pair of diametrically-disposed protruding ridges 78 and a closure member 60, the vessel being normally clamped by a collar 42 to a head 10 which has an inlet 12 and an outlet 25. Ridges 78 are received in recesses formed in a pair of ledges 50 on the collar 42. The rim of the head has cam surfaces 34, 35 which are in sliding engagement with cam surfaces 46, 47 at the rim of the collar 42, and the arrangement is such that, when the collar is rotated to the clamping position, the inlet opening 64 and the outlet opening 65, in the upper closure member 60, communicate with the inlet 12 and outlet. 25 of the head, but when the collar is rotated in the opposite direction it moves axially away from the head so that the vessel 59 can be detached and the filter 74 can be replaced. The left hand part of Fig. 3 shows the collar, the head and the vessel 59 in the clamped position; and the right hand part shows the unclamped position. The liquid to be filtered, introduced through inlet 12, flows from inlet 64 to the exterior of filter bag 74 through tube 62a. The filtered liquid flows through opening 75 in member 76, which is integral with closure member 60, and leaves the assembly through outlets 65 and 25. The threaded portion 16a of a valve stem 16 is in threading engagement with the bore 15 in the upper part of head 10; and this feed-valve is operated by manual actuating lever 18 so as to close the inlet 12 before the collar 42 is rotated to the unclamped position. In order to prevent liquid under pressure from blowing the pressure vessel from the head in the event of the latter being attempted when the feedvalve is not entirely closed, the ridges 78 on the vessel and the stop surfaces 54 at the ends of the recesses on the collar limit rotation thereof towards the unclamping position. In order to release the pressure vessel 59 it can be further rotated to bring the ridges 78 in registry with the openings between the ends of the ledges and moved therethrough.

Title: Hydraulic motor control circuit
IPC: F15B11/16
Filed: 1971-04-19
Abstract: 1306886 Hydraulic motor control circuit BORG-WARNER CORP 19 April 1971 [6 April 1970] 25761/71 Heading F1P A hydraulic motor control circuit comprises a control valve 10 Fig. 2 having a pressure inlet port 13 Fig.1, a motor port 14, a return port 18 and a movable spool 11 which in a first position shown in Fig.1 isolates the inlet port 13 from the motor port 14 and in a second position e.g. moved to the right connects inlet port 13 to motor port 14 and the circuit also includes a by-pass valve 80 connected at 82 to inlet port 13 and to a pressure supply 100, connected at 83 to port 18 and to a return line 109 and connected at 81 by means of a line 115 via a logic system 50 e.g. a shuttle valve 51, 64 Fig.1A to said return port 18 and when spool 11 is in its second position to motor port 14 whereby by-pass valve 30 is operative to by-pass fluid from source 100 to sump 101 in response to a predetermined difference in the pressure at port 13 and pressure in logic system 50 when spool 11 is in either of its two positions; said by-pass valve 80 having means e.g. a piston 156, Fig.3, responsive to pressure in motor port 14 to increase said pressure difference at which the by-pass valve opens when spool 11 is in the second position. By-pass valve 80 comprises a hollow spring biased spool 124 with a passage 133 whereby pump pressure at 82 gains access to a first area 125. A second spool area 126 is open to control pressure in line 115 which with spool 11 in its first central position is at sump pressure so that by-pass valve opens fully. An increase in pressure in line 115 is transmitted through a bore 163 to behind piston 156 which is thus moved to the right thereby tending to close the by-pass valve. Spool 124 also encloses a poppet 146 which when unseated by pressure in line 115 transmitted through a bore 142 connects said line 115 through a passage 150 to the return line 109 and thereby acts as a relief valve. Control valve 10 has a second motor port 15 return port 19 and control port 17; ports 16, 17 being connected to inlets 57, 58 of shuttle valve 50 the outlet 56 of which is connected by a second shuttle valve 64 to line 115. A second control valve 10A similar to valve 10 controls a second motor and when both valves are open the higher of the two motor port pressures is transmitted through the line 115 to the by-pass valve 80.

Title: Improvements relating to the manufacture of moulded panels
IPC: B28B1/00
Filed: 1951-11-05
Abstract: 716,199. Moulding building panels. BROCKWORTH BUILDING CO., Ltd., and HAWKSLEY. Ltd., A. W., [trading as HAWKSLEY CONSTRUCTIONS], and JONES, E. H. Nov. 5, 1952 [Nov. 5, 1951], No. 25836/51. Class 87 (2) A method of making a building panel comprises the steps of casting on two separate tables the outer parts of the panel, bringing the tables into a vertical position wherein the faces of the parts previously uppermost on the tables are adjacent but spaced apart, applying bonding material between the panels, and moving the tables apart when the bonding material is set whereby the panel may be removed while in a substantially vertical position from one of the tables. The tables 10, 11, shown in their vertical positions, are each pivoted at 28 on supporting structures 12, 13 and each comprises a rectangular framework for a concrete slab which has a smooth surface 57 and is of double thickness at 58 for counterweighting. The structure 13 is stationary but the structure 12 is mounted on wheels 20, 22 which run on rails 23. There is an additional guide rail for rollers 42, to prevent sideways movement. With the tables horizontal and the structure 12 moved away from 13 the surfaces 57 are prepared by polishing, and coating with a parting liquid, e.g. oil, and wood on metal edgings of the size and shape of the required panel are clamped on the surfaces, on which also doors, window frames or picture rails may be positioned. Into the shallow moulds so formed good quality liquid plaster is poured, followed by poorer quality plaster into which fibrous reinforcement is inserted so that it partially projects. When the plaster has set sufficiently the tables are raised to the vertical position by winches 30 which, when turned by hand-wheels 36, through suitable gearing, apply tension to cables 31 anchored at both ends to semi-circular guide members 29 fixed to the table frames. The structure 12 is then wheeled up to the structure 13 till the two newly-cast surfaces are close together and spacing bolts 60 are placed in position to ensure a panel of constant width. Bars 51 project from the structure 12 and have holes for the hooked ends of bolts 52 whereby, when hand-wheels 54, screwed on the threaded ends of the bolts, are tightened the structures 12, 13 are held against movement apart. Bonding material, e.g. semiliquid grout, is then poured between the surfaces and allowed to set. The two tables are separated, leaving the complete panel on one table, and the panel is removed while still vertical by a hoist. Edging members are advantageously incorporated permanently, one being a metal channel to which attachments may be made for clinging and which further forms a damp course when the panel is in place.
