Patent GB-1298599-A (GB)
Title: Improvements in or relating to a slide valve
Inventor: ANDERSEN ODD
IPC: F16K3/12
Filed: 1970-03-16
Abstract: 1298599 Valves O ANDERSEN 16 March 1970 [14 March 1969] 12618/70 Heading F2V In a sluice valve having a through-flow passage 11, the wedge type valve member 13 has formed therein a blind bore 17, a portion 18 of which is screw-threaded for co-operation with the screw-threads on an actuating spindle 19. A venting passage 28, having a diameter of the order of 1 mm., permits a restricted degree of communication between the blind bore 17 and the recess 12 within which the valve member moves. Alternatively the venting passage may extend along, or axially through, the valve spindle. The provision of such restricted communication is said to inhibit turbulence within the blind bore and hence premature failing of either the valve member or of the spindle.

Title: A method and a machine for lining the inside of tins with pastry
IPC: A21B5/00
Filed: 1943-08-09
Abstract: 569,176. Pie - moulding machines. RICHTER, E. W. Aug. 9, 1943, No. 12810. [Class 87 (ii)] A piece of pastry which is to line a pie tin is placed on a block C, which, shaped to fit a pie tin with “-inch clearance all around and is secured to a steel band A, a greased tin is placed on the pastry, and the bamd moves forward until the block is under a punch D and then stops. The punch descends and presses the tin on tc the pastry, the pastry being thus giver the shape of the tin and the edge of the tin being pressed through the pastry on to the steel band to trim the edges of the lining. The punch then rises, the band moves forward another step, and the operation is repeated on another block. The pastry trimmings are carried to the end of the band and fall off into a trough. The blocks may be electrically heated, to facilitate release of pastry therefrom.

Title: Rotary regenerative heat exchanger
Inventor: DRUMMOND WILLIAM ALEXANDER
IPC: F23L15/02
Filed: 1960-04-11
Abstract: 941,318. Rotary regenerative heat exchangers. JAMES HOWDEN & CO. Ltd. March 23, 1961 [April 11, 1960], No. 12827/60. Heading F4K. A regenerative heat exchanger comprises a rotor 1 mounted to rotate about a vertical axis and closed at the bottom, with an intermediate circular partition 18 dividing it into inner and outer flow paths 23, 24 which communicate at their lower ends, and radial partitions 17, Fig. 2, which divide the passages into sectors containing heat exchange matrices. The hot gas inlet and outlet passages 7, 8 and the cold gas inlet and outlet 9, 10 are arranged in a structure 4 adjustably suspended independently of the rotor 1. The lower part of the inner flow paths 23 contains checker brickwork 49, which forms part of the partition wall 18, and provides passages between the inner and outer flow paths 23, 24. In each sector 23 of the inner flow path, refractory rods are laid in layers, the rods of each layer being parallel to one another and transverse to the rods of adjacent layers, Fig. 3, to form a matrix according to Specification 941,319. The radial partitions are slotted to receive the ends of the rods, which rest on the checker brickwork, and may be shaped to give T-shaped flow paths. The rotor 1 is supported on a ring bearing 3 and driven by chain engaging a toothed ring surrounding the bearing, which rests on a triangular framework 2. The framework 2 is mounted on supporting screws, each associated with an hydraulic jack. In order to allow for thermal expansion and yet maintain the seals between the stationary duct structure and the rotor, the framework 2 is lowered by the jacks to its lowest position, the clearance between the rotor and ducts is measured, and the difference between this clearance and the calculated axial expansion is set off between the upper surface of the framework 2 and the retaining nuts on the supporting bolts, the framework is raised against the nuts by the jacks, and the lower supporting nuts on the bolts tightened. The supporting structure for the framework 2 is arranged so that a trolley may be run under the framework which can be lowered on to it by the jacks and removed with the rotor for repair or replacement. The labyrinth seals, Fig. 7, between the radial partitions of the rotor and duct structure are kept clear of dust and gases by cold air blown up the hub of the rotor to nozzles 27 lying in the seals. In a modification, Fig. 8, not shown, the rotor is supported at its upper end by a steel tube within the rotor hub which is secured to it. The inner tube is rotatably supported on the ring bearing. The inner tube is cooled by air blown through it so that axial thermal expansion of the rotor is downwards only.

Filed: 1923-05-15
Abstract: 197,938. Ravel, L. R. May 19, 1922, [Convention date]. Brakes; setting and controlling device for controlling-apparatus.-The Specification as open to inspection under Sect. 91 (3) (a) comprises brake operating mechanism by means of which the 'brake pedal applies both the transmission brake and the front wheel brakes. The brake-operating pedal 8, Figs. 2 (Cancelled), and 3 (Cancelled), is mounted on a transverse shaft 9 carried in bearings in the casing 1. The shaft carries the planetary members 20 of a differential gear, having driven members 21, 22 connected respectively to the transmission brake and to the front wheel brakes. The member 21 is keyed to the end of a sleeve 10, the other end of which is connected by skew gearing 11, 12 to the spindle 13 which passes through the gear-box and carries at its rear end the operating member 14 for the transmission brake. The lower anchoring member 18 of the brake is carried on an extension outside the gear-box of the shaft on which the reverse gears are mounted. A gear-operating sleeve 15 is slidable on the spindle 13 and can be held in position by spring members 17 engaging grooves 16. The driven member 22 of the differential gear is connected to a lever 23 by means of which the front wheel brakes are applied. The brake operating shaft 9 may also carry the clutch pedal and sleeve for operating the clutch. The brake pedal 8 may be adjusted angularly relatively to the shaft 9 to take up wear. For this purpose, the pedal is loose on the shaft and is pressed by a spring 28 so that a ratchet face on its boss engages a ratchet member 24 fixed to the shaft. The ratchet is normally inoperative, but, when it is desired to take up slack, the pedal and shaft are turned until stops 25, 26 prevent further movement of the shaft. The pedal is then lifted further and turned relatively to the shaft, the ratchet gear allowing it to assume the new position and retaining it therein. This subject-matter does not appear in the Specification as accepted.

A continuous bulk polymerization process for polymers insoluble in the monomer(s) comprises feeding the monomer(s) to a polymerization zone where it is polymerized to a degree such that substantially all the liquid phase monomer is absorbed by the polymer formed and the ambient atmosphere is saturated with monomer vapour, and intermittently connecting the polymerization zone with a lower pressure zone to effect discharge of polymer under pressure differential, the rate of discharge of polymer being controlled in conjunction with the rate of supply of monomer(s) and catalyst to maintain the appropriate degree of polymerization. The lower pressure zone is preferably the first of a series of zones of progressives decreasing pressure to facilitate degassification and particle separation of the product. The zones may be connected for half second periods through a 14mm. diameter valve 12 times per hour or 60 times per hour where the polymerization zone is a 301. or 5001. autoclave respectively. The process is applicable to polymers of vinyl chloride and fluoride and their copolymers with one another or with vinylidene chloride or acrylonitrile. In specific examples vinyl chloride is polymerized using azodiisobutyronitrile as catalyst in various capacity autoclaves and at various rates (determined by catalyst concentration). Specifications 749,086 and 913,724 are referred to.

The spaces 6 extend the length of the high temperature and preheating sections of the kiln and are fired by angularly directed burners 7, secondary air being admitted through ports 8 from the cooling-section C. Combustion products from the spaces 6, and air and gases from the tunnel proper are exhausted to a stack flue 9 under control of dampers 26a and 26 respectively. The ware platform 12 is supported by blocks 28 having bevelled ends facing burners 11, which deliver through ported blocks 16 forming the floors of the combustion spaces 6. These burners may be provided for the high temperature section only, or for both high temperature and preheating sections, and the products of combustion therefrom may pass into the tunnel through gaps between the platform and the tops of the blocks 16, or if these gaps are closed by sand seals formed as shown by depending ribs 19 and grooves 20, exhaust is effected through ported blocks 16<1> into the opposite combustion space. The plates 5 are supported in grooves 21 in the upper faces of the blocks 16 and are held loosely at their upper edges by projections 22, 23. The joints between adjacent plates are preferably unsealed, and deflecting surfaces 5b, Fig. 3, may be formed on their outer of the plates so that the stream of combustion products in the spaces 6 will tend to draw air and gases from the tunnel through the joints. The plates may be panelled, or may have corrugations running vertically, horizontally or at an inclination. Radiation over the height of the plates may be equalised by making them thicker towards the top, by coating them at the upper part with insulating material, by applying a graded coating, or by increasing the depth of horizontal corrugations towards the lower edges of the plates. A modification is described in which the roof of the tunnel proper is formed by an arch of heat radiating plates.
