Patent GB-1588302-A (GB)
Title: Distributing valve and cover device for whipped cream dispenser
IPC: A47J43/12
Filed: 1978-03-03
Abstract: It possesses a hole made up of three consecutive lengths (6, 8 and 10) whose diameters decrease from the exterior towards the interior and a shutoff member (9) pushed by a spring. The shutoff member therefore forms a seal against a valve seat (12) formed in said hole and is guided at the innermost end by an integral pin (11) sliding in the smallest-diameter part of the hole. Said shutoff member has a rod (15) on the outward end with an axial hole so that its interior communicates with the hole of the valve through radial holes (17) and with the exterior so as to provide an outlet for the dispensed cream when the shutoff member is removed from said valve seat. The assembly is so constructed that the shutoff member can be removed into the open position either by means of a control lever, so as to dispense the cream in a controlled manner, or by the accidental creation of excess pressure in the container of cream, so that in this case it acts as a safety valve. <IMAGE>

Patent GB-232207-A (GB)
Title: Manufacture of derivatives of 4-oxypiperidine
Filed: 1925-04-01
Abstract: Derivatives of 4-oxypiperidine are prepared by converting a diallylcarbinol ester or a substitution product thereof into its dihydrohalide and condensing the latter with ammonia or with a primary aliphatic, aromatic or aliphatic-aromatic amine to effect the piperidine ring closure.  The products may be regarded as open-chain tropine compounds <FORM:0232207/2/1> in which R represents hydrogen, alkyl, aryl or aralkyl and X represents acidyl.  In certain cases the ester products are unstable and liberate the free open chain tropine; in any case, the latter may be obtained from the ester by saponification.  The products are medicaments.  According to the examples, (1) the benzoic ester of 2 : 6-dimethyl-N-methyl or -phenylethyl-4-oxy-piperidine is prepared by interaction of the dihydrobromide of diallylcarbinol benzoate with methylamine or phenylethylamine respectively, (2) 2 : 6-dimethyl-N-methyl-4-oxypiperidine results from the saponification of the product of the interaction of methylamine with the dihydrobromide of diallylcarbinol acetate; by treatment with sodium amylate, a stereoisomer can be obtained.  Similarly, by the interaction of the dihydrobromide of diallylcarbinol acetate with alcoholic ammonia, 2 : 6-dimethyl-4-oxypiperidine is obtained, whilst by interaction with ethylamine, allylamine or phenylethylamine, N-ethyl or allyl or phenylethyl-2 : 6-dimethyl-4-oxypiperidine is formed.  Diallylcarbinol is obtained by reacting upon allyl bromide with ethyl formate and zinc filings in presence of ether. Diallylcarbinol benzoate is prepared by treating diallylcarbinol with benzoic acid anhydride.  Three stereoisomers of the dihydrobromide are possible, one of which can be isolated by treatment with petroleum ether.

Filed: 1967-02-24
Abstract: 1,184,111. Moulding gramophone records. CARL LINDSTRÍM G.m.b.H. 24 Feb., 1967 [5 March, 1966], No. 8813/67. Heading B5A. Apparatus for the automatic production of gramophone records comprises operating stations 1-5 equally spaced along a path, a plurality of transfer means each for transferring the product from one station to the next, the transfer means being linked so that each transfer operation occurs concurrently and in a predetermined timed sequence. There are four transfer means, namely, two pairs of separable half rings D and E, a system of grabs F1-F4, and a vacuum grab G, all connected to slide bars C extending through stationary guides 12-15 and reciprocated horizontally by an hydraulic mechanism 16. At station 1 a predetermined quantity of mouldable material is ejected by a dispenser H into the space of the closed half rings D; a suction grab J delivers a label from a magazine L1 and presses it on to the mouldable material, after which the label is released and the grab returned to the label magazine. The slide is then operated to transfer the rings D to station 2, during which transfer the rings are rotated through 180 degrees by the co-operation of a roller 18 with a cam member M. A second suction grab N delivers a second label from a magazine L2 to the upper surface of the mouldable material and supports the material labels whilst the rings D are opened pneumatically and the slide operated to return the rings to station 1. The product is now received by the rings E which convey it to the moulding station 3 where it is secured between opposed centring pins after which the rings E are opened and returned to station 2. The press 9 is operated to mould the record between an opposed pair of moulds, and record flash is received by the open jaws of the pneumatically operated grabs F1-F4. After mould cooling the grabs are closed and the slide moved to convey the record to the turntable of an edge cutting machine O at station 4, the slide is returned. The vacuum grab G lifts the record from the machine O and when the slide is again moved the record is delivered to the stacking station 5 and received on a plate P with an upstanding spindle. The apparatus may be adapted for producing records of different diameters.

Title: Improvements relating to circular knitting machines having spring-beard needles
IPC: D04B15/28
Filed: 1965-03-02
Abstract: 1,057,962. Knitting machines. FRANZ MORAT G.m.b.H. March 2, 1965 [March 2, 1964], No. 8887/65. Heading D1C. In a circular knitting-machine having bearded needles the selection means for pressing the needles includes an electromagnet. The needles 2 are pressed by pressers P each of which is controlled by a spring strip 9. The strips are tensioned by cam 10 and when passing the de-energized magnet 6 slip through a gap in the cam and push the sinkers into the path of the pressing cam 11. If the magnet is energized, a strip passing the gap is retained in its tensioned condition and passes behind the pressing cam, so that the associated sinker clears the pressing cam. Selection of unpressed needles enables tuck stitches to be incorporated in the fabric. Energization of the magnet may be controlled by an electronically sensed pattern film.

IPC: G03B17/42
Filed: 1970-02-26
Abstract: 1302384 Photographic apparatus EASTMAN KODAK CO 26 Feb 1970 [27 Feb 1969] 9246/70 Heading G2A A photographic camera, Fig.1 (not shown), is provided with a metering device having a metering member 19 arranged for movement from an operative position (as shown) in which the film transport mechanism of the camera is inoperative, to an inoperative position Figs.7, 8, (not shown), wherein the film transport mechanism can be operated, such a movement causing the camera shutter 52 to be actuated to take a photograph. Sequence of operation An operator depresses a trigger 42 against the action of a spring 44, thereby depressing a spring blade 65 which in turn applies an anti-clockwise torque (as seen) to a shutter drive lever 59 which is prevented from moving by the engagement of ear 75 and boss 73, so the blade 65 is resiliently stressed. Downward movement of the trigger 42 also moves a cam finger 49 so that a face 79 contacts a control arm 51 so as to rotate the metering member 19 slightly anti-clockwise, thus withdrawing a tooth 25 from a film perforation 41 When this withdrawal is complete, the member 19 is driven to the right by a leaf spring 27, thereby disengaging a pawl member 32 from film winding member 17, and also causing a tongue 71 of the member, 19 to rotate a control plate 67, thereby disengaging the ear 75 and the boss 73. The shutter drive lever 59 is then driven rapidly by the spring blade 65 to rotate the shutter 52 clockwise and uncover exposure aperture 58. The shutter blade 58 is returned to its initial position by a leaf spring 54 (Fig.8). The trigger 42 is now released, but the components remain in the Fig.8 position since a lug 78 engages a notch 76 of the control plate 67. Film is advanced due to rotation of the member 17, hence the member 19 is pulled to the left as the tooth 25 engages the next perforation 41, thereby flexing the cam finger 49 to the left, and also causing the tongue 71 to rotate the plate 67 to disengage the notch 76 and lug 78, thereby allowing the trigger 42 to use under spring action. This movement causes the spring blade 65 to pivot the shutter drive lever 59 back to its Fig.6 position.
