Title: Novel carotenoid compounds and the manufacture of same
Filed: 1955-12-21
Abstract: The invention comprises 4,41-dibromo-15,151-dehydro-b -carotene, 4,41-dichloro-15,151-dehydro-b -carotene and a process for the manufacture thereof which comprises condensing acetylene in a metal-organic reaction with 8 - [21,61,61 - trimethyl - cyclohexen - (21) - ylidene - (11)] - 2,6 - dimethyl - octatriene - 2,4,6 - al-(1) and brominating and chlorinating the resulting 1,18-di-[21,61,61 - trimethyl-cyclohexen-(21) - ylidene - (11)] - 3,7,12,16 - tetramethyl - 8,11 - dihydroxy - octadecahexaene - (2,4,6,12, 14,16)-ine-(9) to give the required 4,41-di-(bromo or chloro) - 15,151 - dehydro - b  - carotene.  The condensation may be effected by reacting acetylene with 2 mols. of aldehyde in a Grignard reaction or by reacting the acetylene in the form of an alkali-metal or alkaline earth metal derivative thereof with 1 mol. of aldehyde in liquid ammonia and condensing the product thus obtained with a further molecule of aldehyde in a Grignard reaction.  Chlorination or bromination with accompanying allyl rearrangement may be effected with concentrated aqueous hydrochloric acid or concentrated aqueous hydrobromic acid. The process is exemplified in detail. Specifications 786,003 and 790,615 also are referred to.

Filed: 1961-05-03
Abstract: 972,837. Pneumatic despatch systems. F. TONNE. May 3, 1961 [May 11, 1960], No. 15970/61. Heading B8A. In control apparatus for pneumatic dispatch tube installations in which electric contacts or magnets are radially arranged on the dispatch containers, the contact strips or magnetic detectors are arranged on the conveyer pipes in parallel helical paths so that the signal is independent of the angular rotation of the container within the pipe. In one example, contact brushes 7, 8, Fig. B, on the container engage helical contact strips 2, 3, Fig. A, on the inner face of the pipe 1 to which different D.C. or A.C. voltages are impressed by a signal generator 9. The response given by different containers is varied according to the different arrangements of diodes, impedances, condensers &c. on each container. The brushes 7, 8 may comprise wires 42, 43, Fig. E, located in metal tubes 37, 38 partly embracing the container body and angularly adjustable over annular contact plates 34, 35 which are separated by insulating material 30 and project through the wall of the container in which a diode 36 is mounted. Arrangements are also described in which the contacts are embedded in elastic rings providing pneumatic sealing for the containers.

Abstract: 1,066,237. Ventilators. LUWA A.G. April 17, 1964 [April 18, 1963], No. 15995/64. Heading F4V. In a quick closure device for shelter ventilators the incidence of a shook wave forces a movable perforated plate or a plurality of spring webs against a seat formed by a fixed perforated plate so as to close the ventilator. As illustrated, the fixed plate 5 has vertical slots 14 and is screwed to wooden slats (4), Fig. 2 (not shown), fixed in the ventilator. The movable plate 10 has vertical slots 17 and is normally biased by springs 11 away from the plate 5. A shock wave in the direction of the arrow 18 forces the plate 10 against the plate 5 when the springs 11 are accommodated in recesses (12), Fig. 2 (not shown). In a modification, Fig. 5 (not shown), an additional, movable, seat (25) is provided having slots aligned with those in the fixed seat. Under the influence of a pressure wave both movable plates are forced towards the fixed plate and under the influence of a suction wave the first movable plate is forced against the movable seating. In another embodiment, Fig. 7 (not shown), the slots in the plates are replaced by rows of holes. In a further embodiment, Figs. 9 and 10 (not shown), a plurality of parallel elastic strip-like webs (39) are provided which under the influence of a pressure or suction wave bow to cover slots in one of two appropriately curved seating plates (30, 31).

Abstract: 171,667. Scherhag, A. Nov. 16, 1920, [Convention date]. Addition to 166,517. Air-heating furnaces.-In a hot-air stove having a combustion chamber casing 11 surrounded by an outer casing 16, as described in the parent Specification, the exhaust fan 13 is positioned inside the casing 16 and is cooled by air induced through the space between the casings 11, 16, the fan being journaled in the casing 16. When used for heating rooms &c., the air for combustion enters the casing 11 through regulable ports 11<1> and is deflected towards the burners 10 by plates 22, the air being preheated by the downwardly radiated heat. The air entering between the casings at the base of the casing 16 may be regulated, and passing upwards mixes with the heated gases rising from the casing 11 and with air admitted into a transverse duct 25 which communicates at both ends with the atmosphere or with the space between the casings, as shown on the left and right hand sides of Fig. 2 respectively, regulating flaps 26 being provided. Air inlets 23, 23<1> also are provided. The casing 11 is surmounted by pivoted flaps 24, externally operated, and deflectors 27, having openings opposite to the suction orifices in the fan casing, ensure a supply of cold air to protect the fan bearings 16<1>. Preheated air under pressure is led by the pipe 28 from the exhaust pipe 18 to the gas supply chambers 30. Thermostats 31 operate gas-supply valves, the casing 16 being strengthened for this purpose by a frame 33. When used for drying, the casing 16 is connected to a duct in communication with the outer air, flap valves being provided in the duct to prevent reversal of the direction of suction.

Abstract: 541,164. Sliding clasp fasteners. WALDES KOH-I-NOOR, Inc. Nov. 18, 1940, No. 16612. Convention date, Nov. 10, 1939. [Class 44] To prevent distortion of the slider of a sliding clasp fastening, as for example in pressing a garment on which the fastening is used, and particularly a garment having a covering flap to hide the fastening, the operating tab is pivoted on the upper plate of the slider and projects, when depressed as shown, beyond the end of the slider, the projecting portion being off-set at 19 so that the free end 20 rests on fastener members 16. The tab thus forms a bridge-like protector preventing distortion, by pressure, of the upper and lower plates 10, 11 of the slider. As shown the slider is formed by bending a blank from which bearing cups 23, 24 are previously pressed up, the blank when bent providing upper and lower plates 10, 11 with the usual side flanges 14, 15 and a transverse connecting portion 12. The wedge member 13 is inserted in aligned apertures, a counter-sunk head lying flush with upper plate 10, and the lower end of the member being upset over plate 11. The tab is formed from a blank which may be apertured as shown, bent to provide a part 18 parallel to plate 10, off-set part 19, and end 20 parallel with part 18, part 20 being long enough to avoid its entry between adjacent members 16. Pivot lugs 21. 22 are entered in the cups 23, 24 by bending the tab transversly to shorten the distance between the lugs, registering the lugs with the cups, and then projecting them into the cups by flattening the tab. An integral lug on the tab is curled to form an eccentric cam 25 which, when the tab is depressed, forces a fastening member 16 into a recess 27 in the lower plate 11 to lock the slider.
