Abstract: 1,006,112. Apparatus for treating glutinous substances. BAKER PERKINS Ltd. May 29, 1964 [May 16, 1963], No. 19446/63. Heading B5A. A machine for forming, compacting or other-. wise handling highly adhesive substances comprises a material-contacting surface at least part of which is porous so that the substance can be clearly released therefrom by the application of fluid pressure therethrough. First embodiment (Fig. 2).-Batter or dough supplied to cake tins 3 is compacted by a tamping device comprising porous steel plates 16 mounted on a shaft 11 which is reciprocated vertically by cams (as 6) acting on rollers (as 9). In order to remove batter &c. from the plates 16, compressed air is supplied thereto as the plates are moving upwardly, the air supply being controlled by a valve 30 actuated by a member 31 connected with the shaft 11. The cake tins are carried by conveyer belts which run continuously, the tins being arrested at the tamping station by stop members (as 24) carried by shaft 11. At this station, the tins operate the arm 28 of a switch 26 controlling a motor driving a shaft carrying cams 5, 6. Second embodiment (Fig. 4).-Metered quantities of dough are fed to and delivered from metering chambers formed in a rotary dividing cylinder 53 provided with one or more transverse bores each containing a piston 55. The pistons are pneumatically operated and have porous crowns 56, 57 for passage of compressed air to disengage a charge of dough when ducts 58 and 60 or 59 and 61 coincide. Piston movement is controlled by adjustable stop means 62. The device for feeding dough to the metering chambers in the cylinder 53 is seen in Fig. 3 (not shown) being similar to that in Specifica-. tion 1,008,472.

The following optional ingredients may also be present in the reaction mixture: an anhydride of an aromatic dicarboxylic acid (at least C 8 ) or of an aliphatic mono- or di-carboxylic acid (at least C 4 ), an aminoplast precondensate containing alkylether groups, a C 2-22  aliphatic diol, another polyfunctional compound containing labile halogen, vinyl or ester groups together with at most one acid, nitrile OH or epoxy group. The starting materials are reacted together, e.g. at 80-120C in an organic solvent, e.g. ethylene glycol monobutyl ether. I may be a diglycidyl ether of bisphenol A. II may have the formula Me(CH 2 ) x NH 2  in which x = 11-23. III may have the formula HOOC(CH 2 ) v COOH in which y = 5-12. The wool may be pretreated with dichloroisocyanuric acid or a salt thereof. In an example wool yarn is first dyed with a reactive dye in a circulation bath and rinsed. It was then placed in a water containing 41. water and warmed to 40C, then 1 Kg. oxalic acid and 0.2 Kg. of a condensate of 1 mol of a C 16-20  fatty amine and 70 mol ethylene oxide was introduced followed by 10 Kg of a product according to the invention. An emulsion formed which was uniformly absorbed on the wool in 20-30 minutes and thereafter the condensation product of tristearoyl ethylene triamine and ethylene oxide was added as softener. The product may be steamed. The treating bath may optionally contain anonyl phenol ethylene oxide condensate, diammonium phosphate and monoethanolamine sulphite.

Abstract: 950,814. Automatic circuit breakers. GENERAL ELECTRIC CO. May 21, 1962, No. 19455/62. Heading H2B. A stripping mechanism for a circuit-breaker includes an electromagnetic tripping device (Fig. 4) comprising an armature 68; a pivoted cam follower 74 limiting the de-energized position of the armature and a cam 81, rotatable to adjust the position of the follower 74 with respect to the armature and adjustable axially on its shaft 82. Each of three poles of a circuitbreaker comprises a movable contact 16 spring mounted 26 on a carrier 17, the carriers of all poles being rigidly linked by a bar 24. The centre carrier is operable through a toggle linkage 34, 36 and overcentre tension spring 41 by a handle 38. The toggle is supported by an arm 29 engaged by a latch 32 of the tripping mechanism which is assembled in a separate removable housing 20. Bimetal tripping elements 56 and electromagnetic tripping devices are associated with each pole of the breaker, each acting on a common trip bar 55 to release the latch 32 and open all the contacts. The action of the bimetal 56 is adjustable (Fig. 7 not shown) and is ambient temperature compensated by a second bimetal 60. In the electromagnetic tripping device the armature 68 is attached to a push rod 69 spring biased away from the core 66. The separation of the core and armature in the de-energized position and thus the current necessary to trip the breaker is adjustable through cam 81 by means of a knob 86. The maximum and minimum current values may be independently preset by adjusting a screw 78 and by moving the cam 81 along its shaft 82.

Abstract: 1511506 Rotary piston compressors ROBERT BOSCH GmbH 13 May 1975 [19 June 1974] 19997/75 Heading F1F In a rotary piston compressor in which the geometric centres M 2  and M 3  of a rotor 11 and the eccentric 7 on which it is mounted are not coincident, with a resulting centre of gravity S of the rotor which would fall on the line M 3 M 2  but at a position beyond M 2 , the centre of gravity is displaced to a point S 1  between M 2  and M 3  by forming bores 12 in the inner race 8 of the rotor 11, thus reducing the pressure with which the rotor acts on the stator wall 2. Further bores 13 can displace the centre of gravity to the centre M 3  of eccentric 7, thus eliminating the dependence of this pressure on rotor speed.
