Title: Improvements in or relating to the treatment of accumulator plates
IPC: H01M10/42
Filed: 1950-01-02
Abstract: 676,318. Accumulators. MELINKOW, N. Jan. 2, 1950 [Jan. 18, 1949], No. 19/50. Class 53. Accumulator plates that have become sulphated are regenerated by charging them in a solution which reacts with the lead sulphate to form an insoluble lead salt and then discharging them and again charging in a solution which converts a part of the lead salt into lead hydroxide and subsequently into lead peroxide. The first charging solution may consist of ammonium carbonate which converts the lead sulphate into lead carbonate, ammonium sulphate being formed simultaneously. The accumulator is then discharged and again charged while caustic soda is added gradually which converts a part of the lead carbonate into the hydroxide and then into the peroxide. The accumulator is then washed out and filled with normal sulphuric acid electrolyte. Instead of ammonium carbonate the bicarbonate or cyanide may be used and caustic potash or ammonia in place of caustic soda. Substances which decrease the surface tension of water such as sulphonates and sulphonated derivatives of alcohols may be added to the charging solutions. The process may be used to protect new plates against sulphation.

Patent DK-19482-A (DK)
Inventor: KORSGAARD VAGN
IPC: E04B/
Filed: 1982-01-18
Abstract: The invention relates to a process for preventing condensation droplets from the ceiling or roof in skating rinks. The cause of these condensation droplets is that the ceiling/roof is cooled to below the dew point of the arena air as heat is radiated to the cold rink. The invention is now based on the fact that between the ceiling/roof and the rink there is hung a heat radiation shield, the bottom side and possibly also the top side of which has a very low emission coefficient, such as, for example, bright aluminium. The acquired effect is that both the actual ceiling/roof and the radiation shield assume the temperature of the arena air, which is higher than the dew point of the air, whereby condensation is prevented. Roughly the same effect is achieved by sticking the heat radiation shield directly to an existing ceiling. Apart from preventing condensation droplets, the heat radiation shield will reduce the energy consumed to cool the rink, owing to the lower radiation from the ceiling. In heated arenas, the heat consumption will also be reduced owing to the lower radiation from the ceiling to the rink.

Inventor: RIBAUDO NICKOLAS A
IPC: E05F15/56
Filed: 1994-04-19
Abstract: A hydraulic door opening or closing device comprises a hydraulic fluid pump motor (7) having two ports connected to each end of integral dual manifold (8, 9) and operating cylinder apparatus (10) by way of two branch fluid lines (11, 12). One branch line is fluidly connected to a particular end of the operating cylinder by way of a directional flow valve (17, 18). The other branch line to the same end of the cylinder is fluidly connected to the cylinder by way of an associated manifold (8, 9). Fluid communication with the cylinder through the manifold (8, 9) is accomplished by providing a plurality of valved openings (21-30) linearly disposed along the end of the cylinder between the manifold (8, 9) and the cylinder (10). As a piston (14) of the operating cylinder (10) passes these openings, a door coupled to the piston (14) is automatically slowed as fluid on the drive side of the piston is returned through the openings to the hydraulic fluid pump (7). A simplified control circuit coupled to the device provides three modes of operation, an opening mode, a closing mode and a reversing mode from door opening to door closing.

Title: Improvements in or connected with testing machines
IPC: G01N3/10
Filed: 1943-01-07
Abstract: 566,379. Testing physical qualities of materials. AVERY, Ltd., W. & T., and BOWEN, E. Jan. 7, 1943, No. 294. [Class 106 (ii)] In a testing machine primarily intended for fabrics, the load is applied to the specimen automatically by fluid-pressure means at a constant rate irrespective of the rate of extension of the specimen. The specimen c is stretched between a lower cross-head e and an upper cross-head d connected to a known load-resisting mechanism (e.g. a pendulum or springs) and to a load indicator a. The lower cross-head is joined to a piston g in a hydraulic cylinder h connected to a manually-controlled reversing valve fed with fluid from a pump m driven by a constant-speed motor n, Fig. 4, through a change-speed gear o. A relief valve l on the outlet side of the pump m controls the constant rate of loading and to this end the pressure on the valve l is applied by springs q connected to a yoke r moved on rods s by a screw t driven by gearing u from the changespeed gear o. Each revolution of the shaft t occurs in a constant time determined by the setting of the speed-gear o and increases the relieving pressure of the valve l, and hence the load on the specimen, by a given amount. The gearing u can be disconnected by a hand lever v and the yoke r then returns by gravity, assisted by a coiled spring t<2>, to relieve pressure on the valve l. In a modification, Fig. 5, the rate of increase of loading may be finely varied within the major variations produced by the settings of the change-speed gear. The relief valve l is controlled by an additional spring 6 acting on a lever l<1> and stressed by a lever 7 pivoted at 7a and rocked by the yoke r which is operated as described with reference to Fig. 4. The position of the fulcrum 2b of the lever l<1>, and thus the effect of the spring 6 and consequently the rate of increase of the fluid pressure, is determined by the position of a lever 2 set by a screw 3.

Abstract: 392,276. Fluid-actuated valves. GLADIN, W. H., South View, London Road, Hadleigh, Essex. Jan. 6, 1932, No. 419. [Class 135.] An automatic regulating-device for a geyser having a water-heating element 15 connected on its inlet side to a " continuously-on " water supply and on its outlet side to a service valve 58 comprises a disc-like obturating member 35 which has a rim 36 sliding over the mouth 34 of the water-supply conduit 32 so as to open a gas valve 38 to a predetermined extent before the free flow of water commences, the gas lighting from a pilot jet when the valve 58 is turned on. A bell-shaped member 33 is secured to a flange on the conduit 32, and the rim 36 is provided with holes or slots. The stem 37 of the obturating member passes downwardly through a stuffing-box 39 containing a spring- pressed packing, through a gland chamber 40 having a drainage outlet 43, and finally through a second stuffing box 44 into the. gas valve chamber. The outlet 43 is slightly above the bottom of chamber 40 so as to provide a liquid seal above the gas-valve chamber. A head 53 on the stem 37 contacts a bridge 54 on the gas valve 38 when the member 35 is forced upwardly by the water. This connection allows limited angular movement of the valve 38. The spindle 50 of the valve 38 is surrounded by a loading spring 51, adjustable on removal of a cap 52. Water leaving the outlet 13 of the chamber 33 is slightly preheated by passing through a helical tube 14 located between concentric casings 11, 12, the outer of copper and the inner of galvanized iron. The element 15 comprises a closely-wound helical tube of diameter slightly smaller than the tube 14, to which it is brazed at its lower end. Successive turns of the coil 15 are spaced apart by wire rings fastened to two hooks 17 connected by a cross member 18 which carries a spreader 22. The casing 12 and the coils rest on a shelf 23 raised above the bottom of the casing 11 and provided above the burner 25 with a lipped aperture 24. A baffle 29 spaced by brackets above the bottom of the casing 11 allows air to enter and prevents dust escaping. The service tap 58 may be at a remote point. Specification 179,083, [Class 135, Valves &c.], is referred to.
