Abstract: 1,188,139. Inflators. IDEAL TOY CORP. Nov. 14, 1967 [Nov. 29, 1966], No. 51674/67. Heading F1N. A device for inflating a toy balloon 20 comprises a cylinder 24 having a piston 38 reciprocable therein by a hand plunger 36, the connection between the plunger 36 and the piston 38 being such that, during an upward stroke B of the plunger, air enters the cylinder through plunger passages 50 uncovered by a sealing flange 42 on the end of the plunger. During the downward stroke the sealing flange 42 is urged into engagement with the upper surface of the piston 38, thereby closing the passages 50 and causing air to be discharged through a one-way outlet valve 34 in the end of the cylinder. A conduit 18 delivers the air passing through the valve 34 to a mounting fixture for the balloon 20.

Patent GB-1082720-A (GB)
Title: Process for dosing liquids
IPC: A23L29/206
Filed: 1965-12-09
Abstract: In a process for dosing liquids which contain solid components, wherein the solid components are distributed in the liquid, the viscosity of the liquid is adjusted to a level at which the solid components remain in suspension during the dosing process.  The process is particularly applicable to the production of soups which are to be packaged in bags of aluminium foil.  The dosing is preferably effected below 60 DEG C., so that less additive need be added to achieve the desired viscosity.  If the soup is to contain fat as well as the aqueous phase, the viscosity can be further increased by emulsifying the fat, preferably so that the emulsion breaks down on sterilization.  Suitable thickening agents comprise vegetable mucins, starches, alginate, pectin, gua-meal, carob-bean meal, and carragheenate.  Examples relate to the preparation of chicken, meat, and vegetable soups.

Further pressure causes the plates to tilt if the pellet is not square and also to abut sleeves 62, 54 which slide on the shafts 50, 48 against the pressure of springs 76 seated on retainers 80. The tilting of the plates and movement of the shafts 50 as measured by differential transformers 42, 44 give indications of the out of squareness of the pellet ends, whilst the length of the pellet is measured by the translation movement of the armature 86 in transformer 104. from a null position for a standard length. Various forms of swivel plate mountings are described with reference to Figs. 3-5 (not shown).
