IPC: A21B1/46
Filed: 1925-11-26
Abstract: 243,745. Mairich Akt.-Ges. Nov. 29, 1924, [Convention date]. Bakers' ovens.-In a continuous or travelling oven separate goods carriers e are acted upon by chain driving-devices distributed along the length of the oven. As shown the carriers are in the form of wheeled trays, and the oonveying-devices are endless chains m with drivers. Preferably the intermittent chains are run at a uniform speed, while those at the ends may be run in accordance with the operation of the charging and discharging devices; for example, the opening of the inlet door f may operate a clutch so that the drive is transmitted to the adjacent conveyer-device h, while the closing of the door throws the clutch out of action. The oven described has four superposed chambers, two for baking and two for the return of the trays.

Title: Improvements in or relating to the production of fabrics resistant to shrinking
IPC: D06M15/423
Filed: 1934-10-19
Abstract: Fabrics are rendered resistant to shrinking by applying solutions of natural or synthetic resins, or components thereof, which are hardenable by heat, the hardening of the resin on the fabric and the final treatment thereof, e.g. washing and drying, being effected whilst the fabric is tensioned and while preserving the desired final dimensions.  Suitable resins are formaldehyde-urea or thiourea, phenol resins, aldehyde resins, in all stages of condensation and alone or mixed, and shellac.  Those soluble in water may be applied in conjunction with known sizing, hardening, wetting or softening agents, or dyestuffs.  Catalysts for reducing the hardening temperature may also be used.  In an example, a bleached, mercerized cotton fabric is wetted and then passed through a 20 per cent aqueous solution of a urea-thioureaformaldehyde condensation product containing a catalyst, and squeezed until the fabric is twice its original weight; the fabric is then dried in a tenter at at least 120 DEG  C.; it is then washed, rinsed and dried in the tenter so that its final dimensions are those desired.

Title: Method and Apparatus for Packaging Articles.
Inventor: ZELNICK SEYMOUR
IPC: B65B9/06
Filed: 1967-06-29
Abstract: 1,196,773. Wrapping-machines. WELDOTRON CORP. 29 June, 1967 [12 July, 1966], No. 30035/67. Heading B8C. [Also in Divisions B4-B5] Apparatus for enclosing articles in heatsealable web, the articles being placed between opposed folds of a longitudinally folded web which is then sealed about them, includes a loading tray extending between the folds and having means to blow gas, e.g. air, against the upper fold to facilitate entry of the articles. Articles 44 are fed in by a conveyer belt 22 between guides 70 and 42, 46, the latter being arranged and adjustable for different article heights and widths. Articles fall from the conveyer on to the tray 62, the upper surface of which is apertured for blowing air against the web fold 76. As each article enters between the web folds, it obstructs escape of air, causing the fold 76 to be further raised as air flows between it and the incoming article. Web is fed from a driven roll 16 via a dancer roller (not shown) in response to tensionoperated switch means (not detailed). The lower fold passes beneath the tray 62 and the upper fold is supported on arms 68, 80. A pusher 123 operated, in response to an article contacted switch, by a cylinder and piston device 114, sweeps the article off the tray against an earlier formed cross seal, to draw the web beneath L- formation sealing bars 92, 94. Adjustable guides 104, 106, the former being retractable into line with the latter, locate the article through the upper fold. The bars descend to make transverse and longitudinally sealing cuts, any longitudinal waste margin being withdrawn through an aperture by vacuum (not shown). The bars rise and are cooled by an air-oil mist forced through them and the guide 104 withdraws permitting a belt 102 to remove the finished package. The sealing time is controlled by a timer which may be over-ridden by a switch responsive to heat expansion of a heater element in one of the bars. A buzzer operates when the bars are in sealing position. The air-oil mist acts as a release agent on the bars. Switches responsive to undue resistance to lowering of the bars will raise them again if operated. The machine may include means to fold a web (not detailed). The carrier for the sealing bars may include means (also not detailed) to burn a small hole in the web to permit escape of trapped air.

Abstract: 362,080. Greasing baking tins and loaves. LARSON, S. P., 1044, Sierra Street, Berkeley, California, U.S.A. Oct. 8, 1930, No. 30113. [Class 28 (i).] Apparatus for spraying baking-tins or freshly baked loaves comprises a conveyer which conveys the tins through a casing 1 having openings above the conveyer to permit the passage of the tins, the openings being closed by movable doors 6, 7. The conveyer is driven by a motor through reduction gearing and comprises parallel chains trained over sprockets and connected by transverse channel members 26 which support the tins. The tins are fed down over a shoot 31 covered with a. removable gathered fabric 32 which cleans the bottoms and are then received on the conveyer. Pushers 27 move them in batches beneath a shoe member 43 pivoted to a bar 45 telescopically adjustable in a member 47 pivoted at 50. The member 47 carries an adjustable cam 58 bearing on a cam-ended lever 55 pivoted at 56 and engaging a bell crank 60 which actuates an air-blast valve. The grease is supplied from a tank 37 through a valve 39 and pipe 38. When the shoe is not engaged by a tin, the rods 45, 47 hang vertically, Fig. 5, the stop 54 positioning the shoe. The movement of the tins moves the shoe and associated levers into the position shown in Fig. 1, in which position the air valve is open, thus spraying the pans. The casing 1 has an exhaust stack 2. Surplus grease is condensed by baffles 30, gravitates over the incline 8 and through the filter 3 into the tank 9, which has a draw-off tap 10.

Title: Improvements in or relating to thermal motors
IPC: F03G5/00
Filed: 1934-10-22
Abstract: 446,174. Motors operated by variation of atmospheric temperature ; clocks. REUTTER, J. L., 9, Rue du Sommerard, Paris. Oct. 22, 1934, No. 30234. [Class 10] [See also Group XVIII] A thermal motor for winding clocks and the like operates by virtue of the variations in the difference of the pressures of two different fluids which are simultaneously subjected to natural atmospheric or to artificial variations in the temperature. The two fluids may consist of a gas or gaseous mixture and a saturated vapour, or mixture of vapours, or of a saturated vapour and a mixture of saturated vapours, or of two different mixtures of saturated vapours ; one of the gases may be produced by a chemical dissociation the degree of which varies with the temperature, such as that of silver anunonium chloride. The two fluids may be under high pressure, as in the case of ammonia vapour, nitrous oxide, or carbonic acid. The motor shown comprises an outer cylindrical casing 1 mounted to rotate in bearings 2, 3 and containing an expansible chamber 5 which is filled, for instance, with a saturated vapour whilst the space around it in the casing 1 is filled, for instance, with a gas. When, owing to temperature changes, the wall 6 of the chamber 5 moves it carries with it a steeppitch screw 16 engaging a nut 15 secured to an arm 11 pivoted on a shaft 9 and carrying a weight 12. The arm 11 is thus rotated and the weight 12 raised, which produces a couple causing rotation of the casing 1. Ratchets 13, 19 respectively on the shaft 10 of the arm 11 and on the screw 16 are engaged by pawls 14, 20 on the wall of the casing and the wall 6 of the chamber 5, and result in the casing being rotated unidirectionally by the movements in one direction only of the wall 6. The mechanism may, however, be arranged to give unidirectional rotation to the casing from the movements in both directions of the wall 6, or the ratchets may be omitted so that oscillating movement is imparted to the casing. The construction described avoids the necessity of moving parts extending through the casing 1 to transmit the energy. In modifications, the arm 11 is rotated from the moving wall 6 through wires passing round a drum, or through rack-and-pinion gearing. The weight 12 may be of magnetic material and subjected to the attraction of a magnet outside the casing 1, which in this case is of non-magnetic material and may rotate on an axis other than horizontal.
