Title: Improvements relating to electric batteries, particularly for motor vehicles
IPC: H01M2/10
Filed: 1963-06-24
Abstract: 1,024,116. Batteries. DAIMLER-BENZ A.G. June 24, 1963 [June 28, 1962], No. 25089/63. Heading H1B. Opposed side walls of a battery housing have a hollow beading 5, Fig. 4 (not shown), or a channel-shaped beading 5, Fig. 5 (not shown), lined with a reinforcing member which relieves the beading of the clamping pressure of a mounting bolt 7 which passes through the beading. In Fig. 4 the housing is clamped to a support 9 by bolts 7 and nuts 8 which act on reinforcing members in the form of tubes 6. The tubes may be of circular, oval or prismatic section and may be a push fit in the beadings or alternatively may be secured therein by vulcanizing or adhesive. In Fig. 5 the reinforcing lining is a channel section member 12 which is secured in the beading 5 in the same manner as the tube. The mounting bolts 7 may be introduced into the beading from the side. The ends of the reinforcing members may be provided with collars to distribute the clamping pressure. The beadings may extend vertically or diagonally on the sides of the housing.

Title: Inching control for industrial truck
IPC: B60T11/10
Filed: 1960-07-19
Abstract: 900,470. Clutch control. YALE & TOWNE MANUFACTURING CO. July 19, 1960 [Sept. 21, 1959], No. 25095/60. Class 80 (2). A vehicle inching control-system comprises an hydraulic control valve with relatively large and restricted flow passages effective during normal clutch and inching operations, respectively, and an exhaust port which is closed during normal clutch operation and opened during inching movement. As shown, the valve comprises inlet and exhaust connections 20, 32 and a connection 25 to the clutch selector valve, and the spool 35 is formed with a portion 44 of reduced section to provide an annular space 43 of relatively large volume between connections 20, 25 when the spool is in the position shown for normal rapid clutch operation, and under such conditions exhaust connection 32 is cut off by the end portion 48 of the valve spool. For inching movement of the vehicle the valve spool is moved to the left against a compressionspring 52, the space 43 being cut off by a portion 50 of the spool so that flow between connections 20 and 25 then takes place only through a restricted passage 51, the exhaust 32 being progressively opened by a tapered portion 49 of the spool. The arrangement ensures that under all conditions of operation there is an adequate supply of liquid to the torque converter and to the clutches for lubrication and cooling. Valve 35 may be operated by a pedal which has a small free downward movement before engaging the brake pedal to ensure some clutch slip before the brakes are applied, and permitting, if desired, rapid brake application by depression of the clutch pedal, as described in Specification 817,655.

Abstract: 283,626. Hobbs, W. H., and Lane, A. Oct. 11, 1926. Disinfectants; disinfecting air. - Meat is preserved by storage in a closed chamber at 32-34‹ F. in which it is subjected to air having a humidity of 62-66 per cent, the air having previously been bubbled through a solution of thymol in acetic acid. The solution may be obtained by dissolving 120 grains of thymol in 5-8 ounces of the acid and diluting with boiled or distilled water. In the method described the impure air. is withdrawn from the chamber by a centrifugal exhaust pump 90 through valve 89 and pipe 88, the pump having an exhaust pipe 97 with a valve 98. Air is simultaneously drawn into the chamber through an air drying and sterilizing device comprising a sterilizing chamber 70, containing the thymol solution and provided with a number of concentric baffles, which fresh air enters through pipe 72, valve 75 and pipe 71 and is withdrawn sterilized through a liquid trap 78 having one or more baffle plates 79. Broken coke &c. may be added to the chamber 70 to aid in breaking up the air passing through the liquid. The air next passes through pipe 83 to a drying chamber 95 where it is directed by baffles 103 over trays 101 carrying calcium chloride or other hygroscopic material, and to a final sterilizing device consisting of two perforated or reticulated plates 105, 106 between which is granulated thymol. The treated air passes through pipe 104 into the storage chamber. The air from the chamber may be returned through pipe 73 and valve 76 to be re-sterilized, or if too moist treatment in chamber 70 is omitted and the air from the storage chamber is introduced through valve 89 and pipe 88, direct into chamber 95, valves 86, 98, 76 and 75 being shut. The pipes conveying the air to the storage chamber may be passed through a cooling chamber. Two or more drying chambers may be provided so that the calcium chloride in one may be renewed by removing its top or cover white the others are in operation.

Patent GB-740615-A (GB)
Title: Improvements in or relating to springs
IPC: G04B1/14
Filed: 1951-10-31
Abstract: 740,615. Spiral springs. UHRENFABRIK SENDEN GES. Oct. 31, 1951 [May 2, 1949], No. 25492/51. Class 108 (3). [Also in Groups XVIII and XXVI] The invention relates to spring-actuated driving mechanism of the kind comprising a spiral spring 1 disposed concentrically between, and connected at its ends respectively to, a rotatable core 17 and an outer cylindrical housing 13. The band forming the spring 1 has a transverse curvature when in its relaxed rectilinear condition. The ratio of transverse curvature may vary progressively along the length of the spring. When the mechanism is unwound (Fig. 6), the transverse cross-section of the outer end of the band, and of most of the coils, is rectilinear. The cross-section of the portion A leading from the innermost coil to the point of attachment on the core 17, is transversely curved. As the spring is wound up by relative rotary movement between the core 17 and the outer housing 13, the transverse curvature of the portion A progressively disappears, and a similar transversely-curved portion B appears at the other end of the spring (Fig. 10). When the spring is fully wound (Fig. 12, not shown), it is tightly coiled on the core 17 and the portion A has disappeared. In the construction shown, the invention is applied to a watch mechanism. It may also be applied to driving mechanism for cameras, gramophones, games, and typewriter carriages. A characteristic curve of the mechanism is included (Fig. 16, not shown).

Patent GB-639678-A (GB)
Title: Improvements in cleanout systems for filters
IPC: B01D35/16
Filed: 1947-09-22
Abstract: <PICT:0639678/IV (c)/1> A "wet clean-out" system for tanks housing filter elements used for filtration of dry-cleaning solvent prior to recovery or re-circulation in dry-cleaning plants comprises a jet positioned within and adjacent to the bottom of, the filter tank, for introducing a flushing liquid to agitate accumulated dirt, and outlet adjacent the jet for withdrawing suspended dirt, and a valve in the outlet, the valve incorporating a "pusher plate" which covers the outlet opening when the valve is closed, and causes accumulated dirt to be removed from the outlet opening when the valve is opened (see Groups I and XVII).  A tank 10 housing filter elements 11 from which filtered solvent is withdrawn through a manifold 12 is periodically cut out of the dry-cleaning system when sufficient dirt has accumulated on the bottom of the tank after repeated back-washing of the elements 11.  Solvent is first drained to the level of a pipe 13, and that remaining in the tank is circulated through pipes 15, 16, 17, 19, 20 and 22 by a pump 14, also cut out of the dry-cleaning system by closing of the valves 25 and 27.  From pipe 22 solvent is forced into the bottom of the tank 10 through a slot 24a in an elbow 24 to set up a cyclic circulation for re-suspending the dirt, and through a hole 28a in a plug 28 for removing accumulated dirt from the vicinity of a valve 29.  After a time the circulation is discontinued, and valve 29 is opened by screwing in a threaded rod 31.  The valve disc 32 at the other end constitutes a "pusher-plate" for removing any remaining unsuspended dirt from the opening, and the suspension is pumped via pipes 30, 35, 36, 17, 19, 37 to a centrifugal extractor 34 incorporating a strainer bag via pipe 38, or to a body of water contained in the lower tapered portion of a settling tank 41 via pipe 47.  In the latter case the mixture is allowed to stand for at least four hours, after which solvent is withdrawn through pipes 46 and a dirt-and-water mixture through pipe 49.  A settling tank such as 41 may be provided in addition to a centrifugal extractor such as 34.
Patent GB-1267713-A (GB)
Title: A container for elongated articles
IPC: F42B39/26
Filed: 1969-05-21
Abstract: 1,267,713. Containers for bottles &c. NEDERLANDSCHE WAPEN-EN MUNITIEFABRIEK DE KRUITHOORN N.V. 21 May, 1969 [22 May, 1968], No. 25974/69. Heading B8P. [Also in Divisions F3-F4] A container comprises a box 1 and a partitioned carrier 2, with at least two series of cooperating abutment members which vary the vertical position of the carrier inside the box according to the orientation of the carrier to the box before insertion, for cartridges 12, bottles &c., of different lengths. The carrier 2 has a platform 5 with a series of holes 6 separated by a longitudinal partition 7 and transverse partitions 8. The longitudinal partition 7 is shorter on one side of the platform 5 than the other, and has projections 17-20, offset toward one end of the carrier 2, formed on the taller side. As shown in Fig. 1, the projections 17-20 abut projections 13-16 formed on the bottom of the box 1. Recesses 21-24 are formed on the shorter side of the platform 5. Articles are held in position in the container by a cover 3 with a resilient lining 4 abutting the ends of the articles. With the carrier 2 rotated 180 degrees about its vertical axis prior to insertion and then inserted in the box, the projections 17-20 project between the projections 13-16, and the platform 5 is lower with respect to the cover 3, Fig. 2 (not shown). With the carrier 2 further rotated 180 degrees about its horizontal axis prior to insertion, and then inserted, the shorter side of the longitudinal partition 7 abuts the projections 13-16 and the platform 5 is further lowered with respect to the cover 3, Fig. 3 (not shown). Further rotation of the carrier 2 about its vertical axis prior to insertion, causes the projections 13-16 to engage in the recesses 21- 24 during insertion, and again lowers the platform 5 with respect to the cover 3, Fig. 4 (not shown). Alternatively the vertical positional variation of the carrier 2 can be achieved by ribs of varying height formed in the sidewalls of the box 1 in connection with arrangements of recesses formed in the edges of the platform 5, Figs. 6-12 (not shown). The spaces in the carrier 2 can retain articles of smaller diameter by the thickening of the partitions 7, 8 at 26, 27 and the introduction of the interrupted platform edge rib 25, which reduce the width of the partitions.
Patent GB-426265-A (GB)
Title: Process for the production of glued or stuck materials
IPC: C09J157/00
Filed: 1933-09-20
Abstract: Aqueous dispersions obtained by polymerizing monomeric polymerizable organic vinyl compounds while emulsified in a liquid medium in which they are practically insoluble are used as adhesives for the production of glued materials from paper, wood, leather, cork, textiles, felt, asbestos, stones and other materials capable of absorbing liquids to a certain degree. Suitable products are those obtained by polymerizing emulsions of water-insoluble carboxyl derivatives of an acid of the acrylic series in accordance with Specifications 351,508 and 358,534. Other suitable dispersions are those in which a certain proportion, up to about 15 per cent, of acrylic acid is also polymerized.  Suitable vinyl compounds are the methyl, ethyl or butyl ester of acrylic acid, acrylic nitrile, styrene or vinyl chloride.  Materials such as glue, gelatine, water-soluble cellulose ethers, aqueous dispersions of celluloid, softening agents such as alkyl esters of phthalic acid, aryl esters of phosphoric acid or chlorodiphenyl, or fillers may be added to the dispersions.  The viscosity of the dispersions containing interpolymerized acrylic acid is increased by the addition of alkaline reacting substances such as ammonia, caustic soda or potash or amines, e.g. diethylaniline, triethanolamine or polyethylenepolyamines.  The surfaces of the articles are coated with the dispersions, then brought together and allowed to dry, with the use of increased heat and/or pressure if desired. According to examples.  (1) The tapered ends of a driving belt are brushed with an aqueous dispersion of polymerized acrylic acid methyl ester obtained by polymerization of an aqueous emulsion of the monomeric est<\>per, prepared with turkey red oil and the sodium salt of di-isopropylnapthalene sulphonic acid, with the aid of hydrogen peroxide between 70 and 95 DEG  C.  After drying, the surfaces are united in a hot press at about 80 DEG  C.  (2) Chrome leather shreds are added to an aqueous dispersion of polymerized acrylic acid ethyl ester (obtained by boiling an aqueous emulsion of monomeric acrylic ethyl ester with the sodium salt of a -hydroxy-octodecane sulphonic acid and hydrogen peroxide).  The resulting pulp is filtered, dried and pressed between hot rollers at 60-80 DEG  C., forming an artificial mass of good strength and elasticity.  (3) Two pieces of leather are coated on the split p  side with a mixture of the aqueous dispersion employed in Example (1) and an aqueous dispersion of a mixed polymerization product of vinyl chloride and vinyl acetate (obtained by polymerization of an aqueous emulsion prepared with turkey red oil and the sodium salt of a -hydroxy-octodecane sulphonic by means of hydrogen peroxide at 50-55 DEG  C. in a closed vessel). After drying, the surfaces are united in a hot press.  Alternatively, the coated surfaces may be moistened with a solvent such as acetone or by a solution of the polymerization product in a solvent, and united by pressure alone.
