Title: Improvements in delivery mechanism for printing and like machines
IPC: B65H33/00
Filed: 1945-07-20
Abstract: 599,088. Delivery apparatus for printing &c. machines. HOE & CO., Ltd., R., and TURRALL, G. July 20, 1945, No. 18617. [Class 100 (i)] Folded products delivered from a printing machine are delivered in counted batches alternately by two conveyers to two receivers, one of the batches being given an angular movement prior to the two batches being superposed one on the other, so that the assembled batches are distinguished from one another by the different orientation of the folded edges. The products leaving a printing-' machine are delivered in counted batches alternately to two conveyers 1, 2, as described in Specification 599,082, with their folded-edges leading. The batch on the lower conveyer 2 is deposited as a pile on a receiver 9, 11, in the form of a grid, whilst the batch on the upper conveyer is piled on slats 6 on a conveyer 7 against stops 8. A tubular shaft 12 carries the support 10 for the receiver 9, and is rotatable with but movable axially along a shaft 13 carrying it. After a batch has been deposited thereon, the receiver 9 is turned through 180 degrees and at the same time raised so that it becomes positioned above a fixed table 24 situated at the delivery end of the conveyer 7. The receiver 9 is now lowered and passes through the table 24 to deposit the batch thereon with its folded edges pointing in a reverse direction. During this period, a batch has collected on the slats 6 and the conveyer 7 is now operated to deposit this batch on the top of the batch from the conveyer 2, the two batches being distinguishable by the displacement of their folds. Arms 45 on a conveyer 44 move upwardly through the table 24 to carry the batches away. The table 24 is adjusted in height so that the top of the first batch is at the correct level for receiving the second batch. To oscillate the receiver 9, a gear 14 on the 'shaft 13 engages a pivoted segmental gear 15 carrying a roller 17 running in cam groove 18<1> of a member 18 driven by gearing 19, 20, 21, 22 from a part of the machine. Fast with the member 18 is a similar grooved member 32 with a follower-roller 33 on a pivoted arm 34 having a roller 37 riding in a slot 38 in a member 31 which is oscillated thereby. The member 31 through gearing 30, 29, and a rack 28 attached to the shaft 12 imparts the up-and-down movement to the receiver 9. The intermittent movement of the conveyer 7 is obtained from a mutilated gear 41 driven from the machine. Members 46 pivoted on the conveyer 7 and which push the batch therefrom on to the table 24 are controlled by a cam track 47.

Title: Process for purification of solvents
IPC: C08J11/02
Filed: 1947-07-15
Abstract: Solvent mixtures of at least one chlorinated aliphatic hydrocarbon with one or more aliphatic alcohols contaminated with water and/or acidic constituents are purified by treatment with anhydrous potassium carbonate.  Solvent mixtures specified are methylene chloride, ethylene dichloride, chloroform and propylene chloride admixed with aliphatic alcohols, e.g. butyl and amyl alcohols and their homologues as described in Specification 421,768.  The purification may be used as a final step after other methods of physical or chemical separation have been applied and is of importance in the recovery of solvents used in the manufacture of photographic film bases.  In examples (1) a mixture of 1 part methylene chloride, 1 part chloroform and up to 8 per cent by weight butanol is treated with anhydrous potassium carbonate in the ratio of 2300 lbs. of solvent to 46 lbs. of carbonate, when after half an hour the solvents are separated the acid and water content thereof is shown to be considerably reduced as also in (2) where a solvent mixture of the same composition as in (1) condensed from the continuous casting of photographic film base is treated by passing over a bed of anhydrous potassium carbonate 1 lb. of the latter per 160 lbs. of solvent being used it being stated that this ratio is sufficient where the water and acidic impurities do not exceed 0.7 per cent of the treated solvents.  The Specification as open to inspection under Sect. 91 refers to the purification of chlorinated hydrocarbons by themselves and in examples (1) methylene chloride and (2) ethylene dichloride are treated for 20 minutes with anhydrous potassium carbonate in the ratio of 1 part of carbonate per 10 parts of solvent.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in valves and valve gears for internal combustion engines
IPC: F01L5/06
Filed: 1919-03-07
Abstract: 139,406. Hall, J. W. March 7, 1919. Valves; valve-gear.-Exhaust and scavenging ports 21 or 21, 22 at one end of the cylinder, and charge-inlet ports 23 or 23, 24 at the other end are controlled by a single sleeve valve 20 in the cylinder, so that air is drawn in during the first half of the suction stroke and expanded below atmospheric pressure, and a rich mixture is drawn in towards the end of the stroke; the compression and power strokes take place, in the usual manner; at the end of the power stroke, the charge-inlet port is closed and no exhaust gases can pass into the induction pipe; and during the exhaust stroke, a. draught of scavenging-air passes through the combustion chamber. The invention is shown as applied to a radial-cylinder engine comprising two sets of nine cylinders 1, 4 with the valve-gear arranged between them. The valve-gear comprises cam-grooves 40, 41 formed in the adjacent faces of crank-disks 31, 32 which run on rollers 28 in races 34. Each valves-rod 35, or 36, has a cross-head at its lower end, in which slides a shuttle 37; one end of the shuttle engages the groove in one cam-disk during the working and exhaust strokes, and in the other cam-disk during the suction and compression strokes, the grooves being inclined at their ends so as to transfer the shuttle from the one to the other. The grooves are found to effect the following movements r.f the valves, which are not the same during successive pairs of strokes. At the end of the working stroke, the sleeve port is below the inlet port and the sleeve is moving downwards and opening the exhaust. The sleeve reaches its lowest position at the end of the exhaust stroke with the exhaust fully opened, and scavenging-air is blown through the combustion chamber whilst the exhaust ports are opening either by the movement of the engine through the air or by means of a pump. During the first half of the suction stroke, whilst the exhaust ports are closing, air is drawn in; this air is then expanded below atmospheric pressure while the sleeve continues to move downwards. At the end of the suction stroke, the sleeve is stationary with the inlet ports in full register with the inlet ports in the cylinder, and the new charge is drawn in when the piston overruns the inlet ports.

Abstract: 892,332. Knitting-machines. ROSENTHAL, H., and SIMON, L. June 13, 1958, No. 19058/58. Class 74 (2). [Also in Group XXIX] An hydraulic system is provided for the control of the striping device at each station of a multi-feed circular knitting machine in which similar movements of the striping device are effected in the same sequence at each station, but with a phase difference between the stations. Transmitters, equal in number to the number of movements at a station, each comprise a piston 8 actuated from cams 4 on a pattern chain 3 by levers 5. The pattern chains 3 co-operate with sprocket wheels on a common shaft 1. Each transmitter supplies liquid to a port 12 of a distributing valve, each port 12 leading to an annular groove registering with a passage through a rotatable disc 14 fast with shaft 1. As the disc rotates the passages register with sets of ports 13 in the valve casing, each set of ports leading to the receivers 11a, 11b . . . at a knitting station. Thus, for any particular position of the valve disc various receivers at the various knitting stations are in communication with the transmitters, and those receivers will be actuated which communicate with the transmitters which are actuated by a cam on the associated pattern chain.

Abstract: 749,271. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. July 9, 1954 [July 10, 1953], No. 19212/53. Class 39 (1). After sealing the stem into the tubular envelope of a discharge lamp supported in a horizontal position, the waste cullet beyond the seal is forced away by the impingement of a stream of gas at a glancing angle. A suitable arrangement is shown in Fig. 2. As soon as the glass envelope 4 is softened and sealed to the flange of the stem 15, compressed air is introduced through a tube 20 into an annular head 19, which directs inclined jets of air through openings 21 to force away the cullet portion. To compensate for the formation of a partial vacuum within the tube, a secondary supply of air may be introduced. This method enables both ends of the tube to be sealed simultaneously, thus obtaining more accurately a predetermined seal-to-seal length.
