Filed: 1921-12-16
Abstract: 189,362. Arnavat, L. Dec. 16, 1921. Bottles, non-refillable.- An obturator for rendering bottles &c. non-refillable, comprises a cylindrical casing 1 secured in the bottle neck by a sleeve, or packing 20, and formed with the inside diameter of its inner end smaller than that of its outer end, so that a minimum of resistance is imposed upon the motion of a disc-valve 6 and a float 7 which slide therein. The float and valve are pressed against the valve seat by a ball 8, which, when liquid is being poured from the bottle, rests in a hollow 9 formed by ribs 10 which separate, openings 17, 18 in a cover 16. and provide a shoulder 12 which retains the ball in a position in which it maintains the closure of the valve 6 when the bottle is horizontal. At the inner end of the casing a cup 14, which is shaped to form a seat for the inclined edge of the valve 6, is provided with projections 15 which break up the liquid into streams and cause it to flow through the orifices 17, air being admitted through the inlets 18.

Patent GB-307137-A (GB)
Title: Improvements in the manufacture of esters
IPC: C07C67/20
Filed: 1927-12-21
Abstract: 307,137. Imperial Chemical Industries, Ltd., Gibson, W., and Payman, J. B. Dec. 21, 1927. Esters; acetamide. - Aliphatic acid esters of aliphatic or alicyclic alcohols are prepared by reaction between an aliphatic acid amide and an aliphatic or alicyclic alcohol in the presence of an inorganic metallic salt, such as zinc chloride or sulphate, mercuric chloride, or zinc chloride ammonia. The ammonia evolved in the reaction may be recovered or used in the preparation of formamide or acetamide bv reaction with carbon monoxide or keten respectively. In preparing formates which boil at a lower temperature, than the corresponding alcohol, it is preferred to carry out the reaction under reflux in such a way that the ester is removed while the alcohol is returned to the reaction vessel. The reactions may be conducted at ordinary, reduced, or elevated pressure, and the alcohol should preferably be anhydrous, although a solvent or diluent may be present. In the examples, (1) n-butyl formate is prepared by reaction between n-butyl alcohol and formamide in the presence of zinc chloride or sulphate or mercuric chloride; (2) isoamyl acetate is prepared by reaction between isoamyl alcohol and acetamide in the presence of zinc chloride; (3) ethylene glycol monoacetate is prepared by reaction between ethylene glycol and acetamide in the presence of zinc chlorides; glycerol may be esterified in the same way; (4) cyclohexanyl formate is prepared by reaction between cyclohexanol and formamide in the presence of zinc. chloride. Reference is made also to the manufacture of esters from n-propyl alcohol, iso- and tert-butyl alcohols, the monoalkyl ethers of ethylene glycol, and propylene glycol and its monoalkyl ethers.

Fruit, which may have been soaked in alcoholic liquor, is solidified by deep freezing and inserted into chocolate cases by a mechanical feeder the fruit being warmed before the cases are capped. As shown brandy-steeped cherries 1 are delivered on an endless belt 2 to a deep-freezing plant 3 where they are carried over a long path on a series of conveyers the last of which discharges them into a hopper 6 of a feeder. The feeder comprises a rotating drum with peripherally and axially equidistant pockets 8, a wheel 9 rotating oppositely to drum 7 ensuring that the cherries drop singly into the pockets. The cherries are held in the pockets by a conveyer belt 13 or a fixed sheet metal cover until they reach the lowest portion of the drum where they drop into a feed hopper 10 into open cases 11 fed under the hopper in moulds 12. Plungers 14 may be provided to dislodge the cherries 1 from the mouth of the feed hopper 10. Moulds 12 travel on a conveyer belt 15 and after the moulds receive the cherries they are carried under a presser device 16 comprising a ram holder 17 with a number of small rams 18 side by side. A main ram 19 pushes rams 18 down to push the cherries into contact with the floor of the cases. Liquid or cream filling is then added and the cases are capped by an extruder.

Abstract: 1475356 Radar BKR Inc 8 Aug 1974 34915/74 Heading H4D To enable information derived by a radar, e.g. a ship-borne PPI radar, to be used at a future date, e.g. at a collision enquiry, the video signal, trigger signals, radar bearing and ship's heading, are recorded on a video recorder-e.g. tape- and for replay into a PPI display at said future date, the recorder having a broad band video channel on which the combined video and trigger signals are recorded, a second or control channel on which the radar bearing signals are recorded, and third or audio channel on which the ship's heading is recorded. The negatively going video pulses 36, Fig. 3, are inverted and limited at 42 for combination at 44 with the trigger signal 38. The radar bearing signal 40 in the form of a 30 Hz sinusoid, is converted to a 60 Hz pulse train at 48 before recording. The ship's heading signal in the form of a pulse 52 is converted at 54 to a burst of 5 kHz which is then frequency multiplexed at 56 with speech signals (100-2500 Hz) and auxiliary data (7 kHz). For playback Fig. 4, the video channel signal is fed to a circuit 72, 74 including a first pulse activated bi-stable, which separates out the trigger signals 76. The signals from the control track are converted back to a 30 Hz sinusoid at 82 and then to two 30 Hz signals in quadrature for application to the windings of a deflection two phase motor. The signal from the audio track is frequency demultiplexed by filters 102, 104, 106, 112 the ship's heading signal 110, speech signal and the auxiliary data. Detailed transistorized circuits for the various items shown, are given Figs. 5 to 10 (none shown).
