Abstract: 864,565. Shovelling machines. BAMFORD, J. C. Jan. 20, 1959 [Feb, 1, 1958], No. 3370/58. Class 68(1). A frame secured to a tractor chassis and supporting a shovel assembly is specifically constructed to serve for the hydraulic systems of the tractor as a reservoir or supply tank having a large surface area that will ensure of adequate cooling of the liquid in the frame. The frame consists of a pair of spaced brackets 18 clamped on either side of the tractor about the housing of the rear axle thereof. At the front end of each bracket is secured a hollow upright beam 14. To this beam between the ends thereof is secured a further forwardly extending beam 15 that is bolted at 36 to the tractor chassis. The forward ends of the beam 15 are connected by a hollow beam 16. Exhausted liquid from an hydraulic circuit enters the top of an upright beam 14 and passes down this beam and through a port 17 into the associated beam 15. The liquid then circulates through the cross beam 17 and the other beams 14, 15. The piping from the pump and from the exhaust of the hydraulic systems passes through the beams 15 from the rear to the front thereof before being connected to the upper ends of the beams 14.

Filed: 1966-01-25
Abstract: 1,141,221. Delivering measured quantities of liquid. WALKER MFG. CO. 25 Jan., 1966 [29 Jan., 1965], No. 3398/66. Heading B8N. [Also in Division F2] A metering valve 86 comprises a resilient bladder 98. As pressure in passage 92 in - creases, a portion 104 expands away from ball 108 and expels fluid from chamber 120 into the supply line 88. Pressure in 88 and the resiliency of bladder 98 then causes portion 104 to contract and engage the ball, thus trapping a metered quantity of lubricant in chamber 110. The ball is then forced out of engagement with neck 106 and fluid flows into chamber 120 preventing back flow from line 88 into chamber 120 of an equal quantity of fluid.

Title: Improvements in photographic camera shutters
IPC: G03B7/083
Filed: 1966-01-26
Abstract: 1,093,731. Electronically controlled photographic shutters. PRONTOR-WERK ALFRED GAUTHIER G.m.b.H. Jan. 26, 1966 [March 19, 1965], No. 3410/66. Heading G2A. A photographic camera shutter having an electronic timing device controlled in dependence upon the lighting by means of a photo-electric resistance (F) Fig. 2 (not shown), the release of the shutter to close being effected by means of an R-C circuit, is further provided with an indicating device showing by means of lamps (30, 31) (Fig. 2) whether the exposure time required by the prevailing lighting conditions is longer or shorter than a predetermined exposure time, e. g. 1/30 sec., the device being connectable in the circuit of the electronic timing device by means of a switch arrangement (S 3 -S 6 ) (Fig. 2). The lamps are visible in observation windows (39, 40) or in the viewfinder (42) Fig. 3 (not shown) of the camera in which the shutter is housed. The indicating device is operated by means of a test button (32) (Fig. 3) which switches the device into the timing circuit, causing a voltage divider to be formed of the photo-electric resistance (F) and a resistance (R) (Fig. 2), the divider being dimensioned so that a transistor (T 1 ) draws current in the event of a lighting intensity requiring a shorter exposure time than e. g. 1/30 sec., thereby causing the green lamp (31) to light up, and in the event of a time longer than e. g. <SP>1</SP>/ 30  sec. being required, the transistor (T 1 ) is non-conductive and the red lamp (30) lights up. The test button is then released and, if the green lamp (31) has lit up, a hand held exposure is made by depressing the camera release 6, thereby closing a switch 5, and owing to the opening movement of the shutter blade ring 13, opening a switch S 2 , thereby rendering (T 1 ) non-conductive and another transistor (T 2 ) conductive to excite an electromagnet M. By means of an R-C circuit, the electromagnet M is deenergized after a time depending on the lighting conditions, and a lever 16 is free to pivot out of the path of a catch lever 20, which thereby frees the shutter driving mechanism to close the shutter. In other embodiments Figs.4-7 (not shown) the indicating device is switched into the exposure timing circuit automatically on removal of the camera case. The device is switched out of the circuit by cam means (50) (Fig. 4) or by rotation of the shutter blade ring (13") (Fig. 5).

Abstract: Air inhibition of the curing of defined unsaturated polyesters is mitigated by the presence of defined allyl monomers.  The unsaturated polyesters are defined as substantially linear polyesters which do not contain acrylyl or methacrylyl groups and which are polycondensation products of one or more glycols with one or more dicarboxylic acids at least one of which is an olefinically unsaturated dicarboxylic acid.  The allyl monomers are those whose molecule contains an allyl ether group and either (i) the residue of an a ,b -olefinically unsaturated monocarboxylic acid or (ii) the residue of an a ,b -unsaturated dicarboxylic acid partially esterified with a monohydric alcohol. A conventional comonomer, e.g. styrene, may also be present. Specified allyl compounds are polyhydric alcohols, e.g. pentaerythritol, sorbitol, glycerol or 2,2,6,6-tetrahydroxymethyl cyclohexanol, which have been partially etherified with allyl alcohol and partially esterified with, for example, acrylic, methacrylic or crotonic acid or methyl or ethyl hydrogen maleate. In examples curing is effected with methyl ethyl ketone peroxide and cobalt naphthenate.  Attention is directed to the Applicant's prior Specification 928,801 which claims a composition comprising an unsaturated polyester, a vinyl comonomer and not less than 20% based on the weight of polyester of a liquid compound containing at least two allyl ether groups and which may be an ester of an unsaturated dicarboxylic acid.  According to the Provisional Specification the allyl compound may be any containing an allyl ether group and an a ,b -unsaturated acid residue and the polyester need not be free from acrylic or methacrylic groups.ALSO:Polyhydroxy compounds, partially etherified with allyl alcohol and partially esterified with either an a ,b -olefinically unsaturated monocarboxylic acid or a monohydric alcohol partial ester of an a ,b -olefinically unsaturated dicarboxylic acid are used in unsaturated polyester resin compositions (see Group IV(a)).  Polyhydroxy compounds specified are glycerol, pentaerythritol, sorbitol and 2,2,6,6-tetrahydroxymethyl cyclohexanol.  Specified acids and partial esters are acrylic, methacrylic and crotonic acids and C1-C4 alkyl hydrogen maleate ester of sorbitol tetra-allyl ether and diallyl ether of pentaerythritol esterified with one mole each of acrylic and methacrylicacids.  In examples preparative details are given for (1) the dicrotonate ester of pentaerythritol diallyl ether and (2) the mixed maleate ester of sorbitol tetra-allyl ether and ethyl alcohol.
