Filed: 1928-10-26
Abstract: 301,454. Maschinenfabrik Oerlikon Nov. 30. 1927, [Convention date]. Vacuum gauges.-A glow discharge gap is arranged in the vacuum to be measured, with at least one of the electrodes so designed that an abnormal cathode drop occurs whereby electrical values in the gap dependent on the pressure are rendered measurable. Fig. 1 shows a glow discharge gap F in series with a high ohmic resistance R and an alternating current voltage transformer W. A voltmeter V across the gap will give variations depending upon the pressure according to the graph shown in Fig. 2. The instrument may be used with direct current, and in this case especially, the vacuum may be obtained by measuring the flow discharge current instead of the voltage.

Title: Elastically deformable hose particularly for teat cup liners
IPC: A01J5/08
Filed: 1973-07-02
Abstract: 1426190 Milking machines N A VAN STAVEREN 2 July 1973 [30 June 1972] 31366/73 Heading AIM A teat cup has a liner comprising a double walled hose with vacuum operated bellows 4 extending between the inner and outer walls 2, 3 of the hose and disposed radially and axially of the hose. A rotary valve 13 provided in the teat cup shell progressively connects the bellows to vacuum and atmosphere to achieve a longitudinally progressive contraction followed by expansion of the inner wall. Preferably the inner wall in its relaxed state is of generally rectangular section having two long sides and two short rounded sides, and the bellows act on the two long sides. When under vacuum the bellows pull the sides apart and give the inner wall a roughly circular section at that point. The interior of the inner wall is subject to a constant slight vacuum of 4-10 cm of mercury, the bellows are subject to a vacuum of 35-40cm of mercury. The valve 13 is driven by a pneumatic motor 23 and is formed with a helical groove 21 connected to atmosphere during milking and a series of peripheral grooves 17 extending through an angle of about 300‹ and communicating with vacuum by way of the hollow interior of the valve member. Rotation of the valve 13 causes the constriction A to travel down the teat cup (to the left as shown), two longitudinally spaced sets of bellows being under atmospheric pressure and five being under vacuum to give a rapid contraction and a gradual expansion of the inner hose. In order to apply the teat cup to a teat, the groove 21 is connected to vacuum as well as the grooves 17 so that all the bellows are contracted to expand the entire inner wall.

Abstract: 1353811 Labelling device REINHARD WOLF GmbH & CO KG 5 July 1971 [6 July 1970] 31368/71 Heading B8F In a manually held electric labelling device, self adhesive labels 24 on a carrier web 26 pass from a spool 20 between rollers 46, 50 and thence, via roller 66, to an edge 68 of a platen 36. Individual labels become detached at the edge 68 being applied by a rocker member 88 pivoted at an axle 90. The web 26 then passes beneath the platen 36 and thence around a roller 72. Pivoting of the member 88, on the application of a label 26, depresses a switch 92 actuating an armature 34 attached via a pin 40, to the platen 36. The armature 34 and platen 36 move upwards, pressing a label 24 on the web 26 against printing rollers 80. Pawl 56, also attached to the armature 34, engages a ratchet wheel 48 advancing the label web 26 half a label length. Roller 50, being coupled by gearwheel 52 to roller 46, also rotates causing the roller 72 to advance the web 26 by the same amount. Armature 34 is then de-energized, a spring 42 moving the platen 36 back to the position shown. This movement causes an arm 64, which is rigidly attached to the platen 36, to pivot a pawl 60 thereby advancing the ratchet wheel a further half a label length, application of a further label then being possible.
Patent GB-631464-A (GB)
Title: Method of making alkali metal selenides
IPC: C01B19/00
Filed: 1946-10-22
Abstract: Alkali metal selenide is produced by reducing a solution of alkali metal selenosulphate by a metallic reducing agent, e.g. zinc or aluminium, in the presence of caustic alkali.  Aqueous or alcoholic &c. solutions may be employed.  The seleno-sulphate may be produced by dissolving selenium in, say, 10-50 per cent aqueous sodium or potassium sulphite solution; 15-40 per cent selenium reckoned on the weight of the sulphite may be employed. Preferably, all of the reducing agent is first added to the solution, the caustic alkali, say of 30-80 per cent, concentration, being thereupon added gradually.  The reaction mixture should be blanketed with nitrogen, carbon monoxide, &c. Alkali metal selenide crystallizes from the reaction mixture on cooling, and may be purified by recrystallization from hot alcohol.  Alkali metal sulphite in the mother liquor obtained after the precipitation of alkali metal bicarbonate and alumina, say, with carbon dioxide, may be reused in the process.

Title: Improvements in and relating to garment presses
IPC: D06F71/04
Filed: 1930-10-23
Abstract: 358,311. Toothed gearing. JENSEN, C. A., 77, Chancery Lane, London.-(United States Hoffman Machinery Corporation ; 105, 4th Avenue, New York, U.S.A.) Oct. 23, 1930, No. 31918. [Class 80 (i).] A garment press having a constantly running motor is provided with manually controlled gearing, which gives an increased mechanical advantage, for coupling the motor to the pressure-applying mechanism and which may be operated only when the press head has been moved to safe closed position. The press is normally closed manually but the motor may be used for this purpose and in this case automatic means are provided for uncoupling the motor from the press-closing and pressure mechanism when the press head reaches lightly closed position, it then being necessary to actuate the coupling means manually in order to recouple the motor and pressure mechanism to apply the heavy pressure. The toggle links 26, 27, Fig. 1, are connected by link 41 to a disc 42 which is secured to a shaft 43, Fig. 3, and is provided with an internal cam track 65 and two peripheral cams 92a, 118. A worm shaft 37 driven by the constantly running motor drives, through intermediate bevel wheels 45 carried by a spider keyed to the shaft 43, a pair of bevel wheels 46, 47 which are loose on the shaft 43. The spider normally remains stationary owing to the resistance of the toggles, but when a bolt 51 is depressed to engage one of a number of teeth 49 formed around a ring 48 secured to the bevel wheel 47, the bevel wheel 47 is held stationary and the spider rotates thereby rotating the disc 42 to apply pressure to the press. The bolt 51 may be manually depressed into engagement with the toothed ring, but in order that the motor may be used for the initial closing of the press the locking ring 48 is provided with a brake drum 98 with which a brake shoe 96, Fig. 11, may be made to contact to hold the bevel wheel 47 stationary. The brake shoe is moved into braking position by depressing a pedal 113, Fig. 1, which is linked to an arm 111 fast on a shaft 105, Fig. 11, having a bifurcated arm 104 which coacts with the brake shoe stem 99. An arm 116 loose on the shaft 105 is connected by a pin and slot 119, 108 with an arm 107 fast on the shaft 105 and the arm 116 carries a roller 117 which coacts with the second peripheral cam 118 on the disc 42. During the press-closing movement, caused by the engagement of the brake shoe with the drum 98, the roller 117 is free, but before the heavy pressure is applied the raised portion 118, Fig. 1, of the second peripheral cam swings the arm 116 and the shaft 105 counterclockwise, Fig. 1, so that the brake is released and the rotation of the disc 42 stopped and further movement of the press members prevented until the manual control is actuated to depress the bolt 51 into locking engagement with the ring 48.
