Abstract: 693,614. Drying granular material. CHAMBON, Ltd. Nov, 21, 1949 [Jan. 27, 1949], No. 29753/49. Class 34 (ii) [Also in Groups V, XVII and XXX] Moist granular material, e.g. crystallised and moistened sugar, is pressed into lumps in a cavitied drum 5 (see Group V), whence the lumps fall onto plates 23 carried by a continuously-running conveyer 62 driven by a worm 63. Conveyer 62 delivers the loaded plates to a conveyer 64 driven intermittently by a Maltese Cross 72. From conveyer 64 the plates are taken by hoist 65, conveyer 67 and hoist 68, all intermittently moving, through a hot fluidtight chamber 66 which dries the lumps. The plates are then deposited on another intermittently moving conveyer 69 which takes them to a station where the lumps are compacted and packed into boxes. Projections 62a on the conveyers engage the plates, and a brush 62b cleans them. In modifications (not illustrated) the hoist 65 may descend and the hoist 68 ascend, the conveyers may travel obliquely and the hoists may differ in height so that compression and packing are carried out on different storeys.

Abstract: 280,246. Canadian Electro Products Co., Ltd., (Assignees of Matheson, H. W., and Skirrow. F. TV.). Nov. 8, 1926, [Convention date]. Ester condensation products. - Gummy or resinous products are obtained by the interaction of an aliphatic vinyl ester and a saturated aliphatic aldehyde. The reaction may be performed at ordinary or elevated temperature and/or pressure in the presence or absence, of a mineral acid or other catalyst. In one example, a mixture of vinyl acetate and acetaldehyde is heated under pressure for six hours, whereafter unchanged materials are removed, for instance by steam distillation followed by washing. The reaction may be effected also by heating the mixture at ordinary pressure under reflux or, according to another example, at ordinary temperature and pressure. Other examples describe the interaction of vinyl formate with formaldehyde and with acetaldehyde. Vinyl formate is prepared from formic acid and acetylene by a process analogous to that employed in preparing vinyl acetate. The Specification as open to inspection under Sect. 91 (3) (a) states that the vinyl ester or the aldehyde employed may be aromatic. This subject-matter does not appear in the Specification as accepted.

IPC: D05B1/06
Filed: 1926-11-26
Abstract: 270,174. Fairweather, W., (Singer Manufacturing Co.). Nov. 26, 1926. Chain-stitching and double-loop stitching; governing needle-thread. - In a machine forming stitches by a threaded looper co-operating with the needle, the needle loop is held for penetration by the looper by a slender rotary loop-taker which is passed completely through the needleloop and the loop-taking movement, of which takes place in the same direction as the feed, the loop penetrating movement of the looper being opposite to the direction of feed. The needle-loop is not materiallv drawn out until the needle has risen above the work. The looptaker 20 is supported in a raceway in a head 18 mounted on the undershaft 13 and is driven by arms 24. 25 engaging shoulders on the looptaker. The raceway is made slightly eccentric to the shaft, so that the driving arms 24, 25 are slightly parted from their respective shoulders at the time when they pass the engaged threadloop. The looper 30 is carried by a bracket mounted on a hub 26 rotatably mounted on a sleeve 11. and is oscillated by an eccentric 34 on the shaft 18 and mechanism comprising a pit man 35, levers 36, 38 connected by a shaft 37, and a link 39. The under-thread is passed through a guide 32 and the eye 31 of the looper so that a. triangle is formed for penetration by the needle. The needle-thread is controlled by a constant tension 50, rotary take-up discs 45, and an intermittent tension 49 actuated by a cam on the shaft 10, so that increased tension is applied during the tightening of the stitch. The take-up has a rise 53 for drawing up the loop already formed as the needle rises and a rise 54 for partly drawing up a new loop as soon as it is released by the loop-taker, just before which is a depression to allow the thread to slip off the loop-taker without any snapping action. In a modified looper-actuating mechanism. Fig. 14, the looper 53<1> is mounted on a shaft 54<1> parallel with the shaft 13 and actuated by an eccentric 57 and a follower block 56 in which slides a pin 55 projecting from the shaft.
