Title: Improvements in and in the Production of Pectous Substances.
Inventor: BARKER BERTIE THOMAS PERCIVAL
IPC: C08B37/00
Filed: 1918-11-14
Abstract: 125,330. Barker, B. T. P. Nov. 14, 1918. Fruit jelly.-In making extracts of pectous substances from vegetable products, such as apples or carrots, and especially apple or pear pomace, the substance treated is freed from acid before extraction. It is stated that the extract thus made can be mixed with sugar and preserved without jellification, which takes place on the addition of a suitable acid, such as tartaric. The substance treated is washed free of acid with cold water, or the acids may be neutralized with calcium carbonate or alkalies. The substance is then steamed to render the pectous substances soluble, and they are extracted with hot or cold water. The extract may be concentrated. A jelly made with such an extract and strawberries is described.

Title: Thermomagnetic switch
IPC: H01H61/06
Filed: 1965-05-04
Abstract: 1,101,754. Magnetic switches. THOMPSON INDUSTRIES Inc. 4 May, 1965 [11 May, 1964], No. 18672/65. Heading H1N. A thermomagnetic switch for car flasher operation has a cantilever contact spring blade 23, of a material which loses its magnetic permeability upon heating, arranged so that heating current passes along the blade and flux from a permanent magnet 24, having its longest dimension normal to its polar axis, passes across the blade. This enhances the pressure between a contact on the free end of the blade and a fixed contact (Fig. 8, not shown), when attracted by the magnet. The blade may be bowed in section to align with the flux path between polepieces 25, 26 (Fig. 11, not shown), and the magnet may have a blow-out effect on the arc between the contacts (Fig. 10, not shown). The contact carrying free end of the blade may engage a sounder membrane to give audible indication of operation. An electromagnet may replace the permanent magnet.

Title: Improvements in or relating to rotary duplicating machines
IPC: B41L11/00
Filed: 1961-05-24
Abstract: 915,667. Copying documents. RITZERFELD, W. R., and RITZERFELD, G. May 24, 1961 [July 25, 1960], No. 18695/61. Class 100 (2). A. rotary duplicating machine for selective line printing from a master sheet comprises a pair of rotatable printing elements constituted by a printing-drum and a counter-pressure roller, the printing drum being adapted to receive the master sheet with lines of text extending in its axial direction, one of the printing elements being provided with a plurality of pressure members having an outer breadth equal to that of the text lines, and means for sensing printing indications allocated to the printing master sheet lines and moving control means for the pressure segments into or out of the operational range of an arrangement controlling the co-operation of the pressure members with the other printing element. A printing drum 2 carries a master sheet 3 and a number of pressure members 4 which are normally held in a position below the peripheral surface of the drum 2 by springs 5 and 6. A photo-electric sensing device having a lamp 16 and a photo-electric cell 17 is trained on one of three bands 15, Fig. 3 (not shown), of printing indications and the passage of a printing indication causes a reduced light input to the cathode of the cell 17 and the ensuing pulse is amplified at 18 and used to energise an electromagnet 20. The armature of the electromagnet pushes the roller 9 on adjacent operating rod 7, which is carried by a member 4, and rollers 9 and 8 on the rod 7 are thus moved within the range of cams 13. The raised portions of the cams 13 lift the members 4 out of the drum 2 and the elevated surfaces thus formed press the sheet 3 against the counter-pressure roller 24. The sensing device is then moved to a position for sensing the next band 15 of indications. A plurality of sensing devices, one for each band, may be provided, or the impulses for the electromagnet may be obtained by passing a specially marked or perforated tape, Fig. 5 (not shown), through a reading device, the marks or perforations being photo-electrically or electromechanically sensed.

Title: A process for preparing of sterol degradation products
IPC: C07J5/00
Filed: 1939-06-27
Abstract: 530,559. Oxidation of sterols. CHINOIN GYOGYSZER ES VEGYESZETI TERMEKEKEKGYARA, R. T. (Dr. Kereszty and Dr. Wolf). June 27, 1939, Nos. 18724 and 18725. Convention dates, June 28, 1938 and May 30, 1939. [Class 2 (iii)] Neutral sterol degradation products containing a carbonyl group and containing the cyclopentanopolyhydro-phenanthrene nucleus are prepared by oxidizing sterols or sterol ethers and those sterol derivatives in which the hydroxyl group of the sterol is converted into a carbonyl group by an oxygen containing gas such as gaseous oxygen or air preferably in the presence of a catalyst such as a compound of vanadium or manganese. Compounds specified as catalysts include vanadium pentoxide, manganese peroxide, and potassium permanganate. Sterols specified include cholesterone, cholesterol and cholesterol ethers. The reaction is preferably carried out at a temperature of 120‹-160‹C. and in order to ensure an intimate contact of the reactants, the oxidizing gas is preferably introduced through a porous plate. The reaction products are worked up by solution in an organic solvent followed by crystallization, removal of the acidic fractions, distribution between immiscible solvents such as described in detail in Specification 518,266, and chromatographic separation. In examples (1) Vanadium pentoxide is added to fused cholesterone and a rapid current of oxygen passed into the mixture at 170‹C. The reaction product is taken up in ether, filtered and extracted with alkali to remove acidic products. The neutral portion is taken up in petrol, and extracted with methyl alcohol to remove corpus luteum hormone leaving unchanged cholestenone in the petrol ether. The corpus luteum hormone is purified by treatment with hydrochloric acid followed by chromatographic extraction. (2) cholesterone is heated with vanadium pentoxide at 120‹-130‹C. for 40 hours, a current of air being passed into the mass through a Jena filtering plate. The reaction product is worked up as in example (1) to give pure corpus luteum hormone.' (3) Cholesterone is fused with potassium permanganate at 120‹-130‹C. and a current of air passed into the melt through a Jena glass filter for 20 hours. The product is worked up as before to give corpus luteum hormone. The Specification as open to inspection under Sect. 91 includes also the production of any sterol degradation products by the application of an oxidizing agent comprising an oxygen containing gas to a sterol or any sterol derivative. Additional catalysts mentioned included compounds of chromium, iron, cobalt and nickel. This subject-matter does not appear in the Specification as accepted. Specification 513,594 also is referred to.

Title: Improvements in or relating to engine-starter drives
IPC: F02N15/06
Filed: 1950-07-27
Abstract: 673,592. Turning-gear. BENDIX AVIATION CORPORATION. July 27,1950 [Aug. 8, 1949], No. 18818/50. Class 7(v) In 'an engine starter drive comprising a power shaft 1, a sleeve 4 fixedly mounted thereon having spline grooves at one end and a stop shoulder 6 at the other, a screwshaft 11 having clutch teeth 12 at one end slidably journalled on the intermediate portion of the sleeve 4, a clutch member 9 slidably but non-rotatably mounted on the splined portion of the sleeve 4, an abutment 14 on the sleeve 4 limiting movement of the member 9 away from the sleeve, a spring 13 urging member 9 into driving engagement with the clutch teeth 12 and normally holding the screw-shaft 11 against the stop shoulder 6, a control nut 18 threaded on the screw-shaft 11, a barrel member 21 rigidly mounted at one end on the control nut, a pinion 16 slidably journalled on' the power shaft for longitudinal movement into and out of mesh with a gear 17 on the engine to be started and having a driven coupling member 28 fixed thereon, there is provided a driving coupling member 24 non-rotatably mounted in the other end of the barrel member 21 and yielding means, such as spring discs 31, on the pinion 16 urging the coupling members into driving engagement. The pinion 16 and barrel 21 are normally located in extended relationship by a mesh enforcing spring 34 positioned between a stop in the interior of the barrel and one of the spring discs 31; an anti-drift spring 37 is located between a thimble 38 on the stop shoulder 6 and the nut 18. In operation, the rotation of the power shaft 1 is transmitted through sleeve 4, clutch member 12 to the screw-shaft 11 so that the nut 18 and the associated parts are traversed to the right to mesh the pinion 16 with the engine gear 17 whereupon the nut 18 abuts the shoulder 6 so that the screw-shaft 11 is forced leftward against the compression of spring 13 thereby ensuring firm engagement of the overrunning clutch 9, 12, the clutch member 9 finally contacting the abutment 14; torque is now transmitted,through the coupling members 24, 28 to crank the engine; if, however, the required torque is or should become excessive the coupling members will be forced apart against the bias of the spring discs 31 until the overload ceases. Should tooth abutment occur, the axial movement of the pinion 16 is arrested but the barrel and nut continue to move by virtue of lugs 23 on coupling member 24 travelling in slots 22 in the barrel 21 so that the mesh enforcing spring 34 is compressed until the rotary component of the force transmitted through the screwshaft is sufficient to index the pinion and engine gear, whereupon the spring 34 ensures the initial meshing of the pinion and engine gear.

Abstract: 270,137. Hill, J. B. Aug. 4, 1926. Inking-apparatus. - In rotary printing - presses wherein ink-distributing rollers disposed between the inking-rollers and the printing-cylinder consist of alternate metal and composition rollers with their surfaces in contact, the ink is removed from all of the rollers by a sharp-edged blade which is brought into approximately tangential contact with one of tho metal rollers, the ink supply being then cut off and the train of rollers rotated rapidly so that the ink is transmitted from the whole train to the roller co-operating with the ink-removing blade. As shown in Fig. 1 two independent saries of ink-distributing rollers, each consisting of smooth-faced metal rollers 12 alternating with composition rollers 13, convey ink, which is supplied to the top rollers 12, to a cylinder 11 on which printing types or plates are mounted, each series of rollers being provided with the ink-removing devices. The two endbearing bosses 15, Fig. 2, of one of the metal rollers 12 each carry a collar 14 which is adjustably secured by a screw 16 and carries a pivoted arcuate arm 17, the outer ends of the two arms 17 forming supports for a flat plate 19 extending between them adjacent to the surface of the metal roller. The blade 24 is mounted upon the upper surface of the plate 19, with its edge adjacent to the metal roller, and is held thereon by a top plate 27 secured by screws 28, the blade preferably being provided with a series of notches through which the screws extend into the plate 19. The position of the blade relatively to its associated metal roller is adjusted by providing one end of the plate 19 with a lug 20, Fig. 3, which has two or more holes to receive a pin 23 passed through a hole in a lug 22 provided on the fixed collar 14. A fine adjustment of the blade is provided by a series of set screws 29, Fig. 7, located in screw-threaded openings formed partly in each of the plates 19, 27, the inner ends of the screws being in contact with the rear edge of the blade 24, thereby enabling it to be adjusted after slackening its clamping screws 28. The curved arms 17 support a trough 31, Fig. 1, suspended beneath the rear lower edge of the plate 19, so that the ink removed by the blade falls therein after flowing laterally in both directions along the upper edge of the plate 27 and over the ends of the blade. In a modification, Fig. 9, arms 34 mounted on collars 32 adjustably secured to the bearings of one of the distributing-rollers provide end supports for a metal roller 35 adapted to be placed into contact with one of the composition rollers 13. The ink-removing blade 38 is supported on an arm 37 pivoted upon a lug 36 on the arm 34, and may be supported either in or out of contact with the roller 35 by inserting a pin 40 through one of two holes in a lug 39 on the arm 37 to engage a hole at the extremity of the arm 34.
