Title: Egg grading equipment
IPC: A01K43/00
Filed: 1974-03-26
Abstract: 1464174 Egg grading device T O NIEDERER and D A NIEDERER 26 March 1974 [9 April 1973] 13392/74 Heading G1W [Also in Division G4] An egg grading device comprises a plurality of weighing devices 4, 6, 8, 10, 12 arranged side by side along a path and each having a balance beam 18 with spaced egg supporting rails 24 at one end and counterbalance means 22 at the other, the counterbalance means being adjusted such that the weighing devices along the path respond to progressively decreasing weights, an egg transfer bar 14 movable longitudinally in a cyclic path between the egg supporting rails for raising, advancing and lowering the eggs, locking means 28 engaging the balance beams for preventing tilting thereof and periodically moved out of engagement with the beams in timed relationship with movement of the egg transfer bar to permit tilting of the beams during weighing of the eggs after deposition by the bar 14, actuating means 38 located adjacent the weighing devices, and co-operating elements 42, 44 on the actuating means and weighing devices normally held in spaced relation by the action of the locking means but which, when the beams are released by the locking means, are engageable under the action of actuating means and upon tilting of any balance beam during a weighing operation, to positively tilt the balance beam to an egg discharging position. An egg stabilizing means 34 may be provided on each weighbeam. In the modification of Fig. 3, each egg grade has associated with it a group of six weighbeams, and the transfer bar is arranged to transfer an egg from a weighbeam of one group to the corresponding weighbeam of a succeeding group. The transfer bar may have egg receiving hollows and egg locating plastics strips, Fig. 4 (not shown). Each group of weighbeams is provided with a counter 80 operated by egg detectors 72. Each egg detector 72 is arranged, when engaged by an egg, to operate a micro-switch 76 for the time it takes a roller 82 to make a revolution. Roller 82 has protuberances 84 which successively operate micro-switches 78 inter-connecting the microswitches 76 and the counter 80 so that signals from the egg detectors are presented to the counter 80 successively at spaced times. Roller 82 rotates in synchronism with the discharge conveyer.
Patent GB-133935-A (GB)
IPC: B21C37/15
Abstract: 133,935. Schneider et Cie. Oct. 14, 1918, [Convention date]. Ordnance.-Relates to apparatus for imparting to gun barrels and other metal tubes required to withstand high pressures, initial stresses similar to those produced by hooping, by means of liquid pressure applied between the, walls of the bore and a mandrel inserted in the bore; and consists in apparatus whereby the liquid pressure is automatically varied by a cam-controlled relief-valve, so that the stresses imparted to the tube are varied continuously along the length of the tube in accordance with the curve of pressures which the ordnance or other tube will be required to withstand in use. Fig. 7 shows the apparatus combined with the stressing device described in Specification 125,907. The pressure fluid is admitted to the annular space F between the bore of the gun or tube A and a sliding bar C through an axial bore c in the bar. A relief valve G is provided in the external portion C' of the bar and is kept on its seat by a pivoted arm I on which a weight K is slidably mounted. The weight, is connected by a cord L, guided by pulleys on a bracket M, to a slider N. These parts are all carried upon the portion C<1> of the bar C. The slider has a roller n which engages in a cam groove o in a fixed plate p. Pressure applied from the front through the bore z of a closing plug Z drives the bar C along the bore of the tube A causing the roller n to traverse the cam groove o and draw down the slider N. The weight K is thereby moved along the pivoted arm I, and varies the pressure required to lift the valve G to permit the liquid to escape from the annular space F.

Title: Compositions containing organic polymers and a process of producing them
IPC: D06N3/06
Filed: 1950-05-31
Abstract: A composition easily dispersible in water is prepared by precipitating a polar high polymeric organic substance which is not plastic at ordinary temperatures from its aqueous dispersion upon a finely-divided hydrophilic inorganic substance having adsorption capacity, separating and drying the precipitate while avoiding high temperatures, the ratio of the inorganic substance to the high polymer being upwards of 1 : 1.  Precipitation may be effected by addition of a small amount of an electrolyte such as aluminium sulphate.  The polymeric substance may be a polymer or copolymer of vinyl chloride, acrylonitrile, vinylidene chloride or a vinyl ester, and the inorganic substance may be an activated clay such as kaolin, Westerwald clay or bentonite, silica gel or aluminium or magnesium oxide or hydroxide.  Examples describe the use of polyvinyl chloride, copolymers of acrylonitrile and acrylic acid esters and of vinyl chloride with methyl acrylate or dimethyl maleate.  The dispersions or pastes made from the compositions of the invention may be used for the production of foils, films, coatings and impregnations.

Abstract: 1470085 Lubricants; benzylating methylnaphthalenes KUREHA KAGAKU KOGYO KK 27 March 1974 [29 March 1973] 13692/74 Headings C5E and C5F A lubricating oil that is resistant to ionizing radiations contains as the major component or consists entirely of benzylmethylnaphthalene, or a mixture of the mono- and di-benzylmethyhiaphthalenes may be used without separation into its components. Normally solid radiation resistant compounds such as naphthalene, anthracene, pyrene, diphenyl, terphenyl and polyphenyl ether may be dissolved in the oil. Hydrocarbons.-Benzylmethylnaphthalene is obtained by condensing methylnaphthalene and benzyl chloride using a Friedel-Crafts catalyst such as aluminium chloride or a solid catalyst such as silica-alumina or zeolite. The methylnaphthalene used may be either isomer or a mixture of the two; the product is a mixture of isomers. The silica-alumina catalyst is preferred as it is more readily removed from the product. Working up is by neutralization of the HCl formed, washing with water and distilling. The product so obtained may contain a proportion of dibenzylmethylnaphthalene.

Title: Arrangements for blending tobacco
IPC: A24B3/08
Filed: 1953-05-22
Abstract: 778,196. Mixing apparatus. QUESTER, W. May 22, 1953, No. 14457/53. Class 86 [Also in Group VI] In means for blending tobacco, layers of tobacco leaves of different kinds are deposited in a container 7, one on top of another, by an-endless belt conveyer 10, Figs. 1 and 2, which moves backwards and forwards across the container and the resultant pile of tobacco is moved slowly by a conveyer 8, forming the bottom of the container, towards a stripping conveyer 11 having projecting pins 12 which move across the end face of the pile to strip away transverse sections thereof. Each layer of tobacco in the container 7 is formed by leaves of one kind placed on a conveyer 1 by operators 2, which leaves pass through a suction conduit 4 on to a conveyer 6 feeding the reciprocating conveyer 10. The apparatus preferably comprises two containers 7, 7<SP>1</SP>, Fig. 2. side by side in one of which the pile of tobacco is built up whilst the previously formed pile in the other is being delivered to its associate stripping conveyer 11, from which the tobacco is delivered on to separate conveyers 17, 17<SP>1</SP> which deliver it on to a conveyer 14 feeding a conveyer 15 which further blends the tobacco by travelling backwards and for wards over a container 16 to spread the mixed tobacco in layers therein. In a modification the tobacco leaves are passed through a humidifier before reaching the operators 2 and the conveyer 14 delivers the tobacco into a mixing drum prior to its delivery on to the belt 15. In Figs. 1 and 2 the conveyer 11 is arranged to move downwards across the end face of the tobacco pile and the pins 12 are arranged in rows with one pin in each row longer than the remaining pins to prevent tobacco building up at the bottom edge of the tobacco pile. The conveyer is pivoted about its top roller so that it can swing backwards to avoid jamming due to a build up of tobacco. In a modification, Fig. 7, the stripping conveyer 43 is arranged triangularly so that the conveyer moves upwards across the end face of the tobacco pile 42, travels horizontally and then has an inclined portion off which the tobacco drops on to conveyer 45. The top of the tobacco pile is held rigid by a rake 44' and the back of the pile is prevented from collapsing by a removable wall or rake 46a.
