Title: Improvements in or relating to hatch covers more particularly for ships
IPC: B63B19/18
Filed: 1956-12-07
Abstract: 809,625. Hatch covers. DEUTSCHE WERFT A.G. Dec. 7, 1956 [Dec. 9, 1955 ; Aug. 6, 1956], No. 37538/56. Class 113. A closure means for a hatch 2 comprises cover members 1a, 1b, 1c, 1d connected together by chains or cables 7 and having front rollers 4 running on an angle member 5 on the hatch coaming inside a track 6 for grooved rear rollers 3 on the cover members, supporting rollers 12 being provided above and between the running rollers 3, 4 for moving on to supporting track rails 15, so that the cover members are movable from their closed position up to the end 9 of the hatch and there rocked into a substantially vertical stacking position, during which stacking movement the transverse axis passing through the centre of gravity of each cover member is located between the bearing points of the rear running rollers 3 and of the supporting rollers 12 on their respective tracks. A pull A applied to the rearmost cover member 1d causes the cover members to move until the front running rollers 4 leave the angle member 5, the members to move on to friction rollers 13 at the end of the hatch and the rear running rollers 4 to move on to an inclined track 10 leading to a horizontal guide 11, the cover members rocking towards the vertical. The rollers 12 move on to the rails 15 on the inner side of a structure 14 which may also have guides 16 for the rollers 4. The distance between the guides 11 and the rails 15 is smaller than the spacing between the rollers 3 and 12, and the position of the centre of gravity of each cover member is such that the member will remain stacked in a position sloping slightly from the vertical.

Title: Improvements in hay sweep attachments to motor vehicles
IPC: A01D87/08
Filed: 1938-12-24
Abstract: 508,361. Hay-sweeps. BUTLER, L. Dec. 24, 1938, No. 37557. [Class 6 (iii)] The tines B of a hay-sweep pivoted to a vertical frame A secured by brackets A<1> to the front of a motor or like vehicle are moved to and from raised position by a chain H attached at one end to a bar C extending under the tines and at the other to a crank F on a shaft D mounted in the upper part of the frame A and adapted to be rocked by a crank arm J actuated by a pull rope M extending to the attendant. The rope M is attached to a lever K pivoted on the arm J and carries a pivoted pawl N on its shorter arm adapted to engage with a stop J<1> on the arm J. In operation a pull on the rope M rocks.the crank F until it passes the dead centre position when the weight of the tines causes the crank to move backwardly against a stop: the rope M becomes slack and the lever K, due to the weight of its longer arm, assumes a vertical position pulling the pawl N into position behind the stop J<1>. To lower the tines the rope M is again pulled and by the engagement of the pawl behind the stop the arm K, J, forms a cranked lever so that the shaft D can be rocked to move the crank F beyond its dead centre position.

Patent GB-328273-A (GB)
Title: Improvements in and in connection with the process and method of manufacture of porous bodies, filters, diaphragms and the like consisting of porous or porous and non-porous parts made of soft to hard rubber and the like
Filed: 1928-12-20
Abstract: 328,273. Wilderman, M. Dec. 20. 1928. Drawings to Specification. Separators.-In a process for making porous vulcanized rubber articles e.g. filters, diaphragms, and the like, by vulcanizing particles having a semi-vulcanized surface, the particles are maintained at such a temperature that they do not stick together during spreading into the moulds. After compression the particles are vulcanized under such conditions that no moisture reaches them and at such a speed that they form strong bodies. The articles may be wholly porous or strengthened by means of ribs of non-porous rubber or rubber covered metal. Mechanism for spreading the particles, compressing them, and vulcanizing as described in Specification 328,274 may be used. Specification 200,577 also is referred to.
Patent GB-893526-A (GB)
Title: Improvements in means for laying rolled stock flush in cooling beds
IPC: B21B43/12
Filed: 1959-11-06
Abstract: 893,526. Cooling beds for rolling mills. HUTTENWERK OBERHAUSEN A.G., and SCHLOEMANN A.G. Nov. 6, 1959 [Nov. 7, 1958], No. 37682/59. Class 83 (4). [Also in Group XXX] Apparatus for flushing up the ends of stock in a cooling bed comprises a driven conveying roller and a pressure roller which is adjustable towards the conveying roller and is controlled in dependence upon the tip of the rolled stock meeting a contact bar. Stock 5, 6 is carried from a rolling mill in two lines by live feed rollers 2. The stock 5 is braked in a feed channel 3 and lifted by bottom plates 7 on to a holding arm 8 while the thicker stock is braked and lifted by the plates 9 in a feed channel 4. The stock 5, 6 is then transferred by the moving racks 10 of the cooling bed to the first notch of the fixed racks 11 and proceeds across the bed until on arrival at continuously-driven conveyer rolls 12, 13 pivoted pressure rollers 15, 16 are moved down by fluid operated cylinders. The thrust of the idle pressure rollers 15, 16 is independently adjustable by damping cylinders arranged on pivoted levers supporting the rollers. The rollers 12, 15 and 13, 16 co-operate to move the stock 5, 6 respectively in a longitudinal direction until the forward end of the stock strikes a contact bar 24 which initiates the disengagement of the pressure rollers by reversal of the action of cylinders 21. The stock then proceeds across the remainder of the cooling bed with forward ends evenly arranged in preparation for subsequent shearing. In a modification, Fig. 4, pairs of rollers 30, 31 and 30a, 31a acting on respective lines of stock in two-line operation are staggered longitudinally of the stock and all the rollers are driven through vertical spindles 29, 29a, a common gear-box 49 and a continuously-operating motor 34. The pressure rollers 30, 30a are independently pivoted by tension rods 40 and levers 45 operated by an hydraulic slewing gear 38. The pressure roller slewing gear is controlled by an electrical system in sequence with discs 58, 59 which effect the rack movements, the pressure roller being held disengaged until stock reaches the channel between the rollers, whereupon a contact is opened by it to interrupt the selfholding relay. Pressure in the cylinder of the slewing gear 38 is thus released and the pressure rollers 30, 30a move towards the rollers 31, 31a due to the pressure of springs 42. On the ends of the stock striking the contact bars the slewing gear cylinders are again pressurized to retract the pressure rollers and permit the transfer cycle of the stock across the bed to take place.
