Patent GB-470753-A (GB)
Title: Improvements in and relating to jam and marmalade
IPC: A23L21/12
Filed: 1936-01-15
Abstract: A preparation, subsequently to be used for making jam or marmalade by adding an appropriate quantity of water and heating for a short time, is obtained by dehydrating fresh fruit at low temperature under vacuum until the solids form 67-74 per cent by weight of the concentrate and then adding sugar in amount sufficient to form about two-thirds of the jam or marmalade when made.  The product is of substantially granular or crystalline form due to the sugar content and the moisture content is sufficient to ensure that it does not harden.  Pectin, or whole fruit containing absorbed sugar, or both may also be added.  The pectin is preferably added in admixture with the sugar.  The fruit, which may first be subdivided, may be concentrated at about 100-120 DEG  F. in a vacuum pan which in one form may be egg-shaped and formed of a lower half jacketted to take steam for heating and an upper half attached by bolts, &c. to the lower half and connected with a suction device, a double-bladed scraper which may be of curved, e.g. helical, shape to direct the material downwardly being attached to a shaft extending vertically through the pan.  The scraper may carry, projecting upwardly, stirring members which co-operate with fixed stirring members extending from a bar or frame across the vessel.  In a modification, the vacuum pan used is rotated slowly on a horizontal axis and is preferably jacketed except at the ends.  Stationary scraping means operating in the upper portion of the pan may be provided to remove any adhering film.  The production of a concentrate from raspberries is described.  In making marmalade from citrus fruit, such as oranges and lemons, the juice may be concentrated separately from the skins and whites, the concentrates after admixture having a 66-74 per cent solid content.  A quantity of peel preferably sugared as by soaking in a 66-72 per cent sugar solution may be added to the mixture.  The Specification as open to inspection under Sect. 91 comprises also the dehydration of the fruit so that the solids form the greater proportion of the concentrate, and the preparation of fruit cordials. In making jelly marmalade concentrate, (1) lemons are cut up finely, twice the weight of water is added and the mixture allowed to simmer for 30 mins. and filtered, the filtrate being concentrated to one-fourth to one-sixth of its volume and then added to the sugar; (2) the juice is pressed from lemons, filtered and concentrated to one-sixth by weight or by volume, and mixed with dry citrus pectin and the sugar; the skins and whites may be cut up finely, subjected to simmering and filtration, and the filtrate mixed with the juice before or after dehydration. Sugared peel may be mixed with the ingredients in either modification.  This subject-matter does not appear in the Specification as accepted.

Abstract: 702,474. Dispensing articles; coin freed mechanism; delivering measured quantities of liquid. GERRARD, C. H. April 21, 1952 [Jan. 20, 1951], No. 1559/51. Classes 27, 106(5) and 116 A rotatable magazine 1 deposits a cup 2 from a column on a plate 3 which rotates to position the cup under a liquid-delivery tube 4 which dispenses a given quantity, the apparatus being preferably coin freed. The transfer plate 3 with a number of holders 11 for cups is mounted to rotate with a gear wheel 27 mounted on a shaft 17. The gear wheel on its under surface has ratchet teeth 26 engageable by a spring- pressed pawl 25 mounted on part of the operating handle 10. The handle is rotatable through 70 degrees, being released by coin freed or other mechanism which rocks the lever 31 so that the end 32 disengages an arm 15 of the handle whilst a branch 33 disengages from one of a series of recesses 34 in a groove 35'on gear wheel 27. Freeing the handle allows rotation of 60 degrees until the branch re-engages a recess, then lost motion allows rotation of a further 10 degrees of the handle. The gear wheel is restored after rotation to its original position by a spring connection 44. Gear wheel 27 meshes with gear 50 supporting the magazine 1 on a member 54. The magazine has a series of holders 55 for cups and a number of uprights carrying flexible cross-members 65 which pass through a member 67 and a slot provided in the casing to retain the cups. The members 65 are operated by a cam 69 mounted on a screw on a shaft 51 to cause a cup to be released. The members 65 are held in the inoperative position by a spring and are released when the magazine is refilled with cups. The cam is held against rotation on the shaft 51 by a guide 76. Liquid is supplied to a cylinder 80 from a tank 9. The cylinder has a valve 82 with an aperture 85 and the cylinder has an aperture 84; when the two coincide the liquid fills the cylinder. Liquid is dispensed down the tube 4 when an orifice 86 in the base of the valve coincides with an orifice in the base of the cylinder. A shaft connected with the valve has a gear 94 meshing with a gear 95 on the shaft 17. When the apparatus is operated the magazine is rotated and a cup deposited in the holder 11 of the transfer plate is moved under the outlet tube 4, a further 10 degrees rotation of the gear 27 brings both outlet orifices together to allow liquid to flow into the cup. If a foreign body remains in the holder 11 after operation it can be removed by raising a member 101 in the base of the holder by a trip member 103 mounted on the base or if this is not effective a plunger 109 is released to lock the gear wheel 27 and put the apparatus out of action. One end of a door contacts the handle and is opened thereby. The cups press open a door member before passing to the delivery opening and a portion 97 is provided at the further end.

Title: Time delayed controller
Inventor: SCHROEDER CHARLES SCHOERN
IPC: B62B3/06
Filed: 1955-01-21
Abstract: 763,796. Controllers. YALE & TOWNE MANUFACTURING CO. Jan. 21, 1955, No. 1934/55. Class 38(3) A controller has a pedal-operated lever 10 which is spring-biased to a neutral position and is secured to a shaft 19 within a tubular cam-carrying member 24. A spring 27 encircles the shaft 19 and has one end fixed thereto and an opposite end engaged in a slot 31 in the cam-carrying member. Thus rotation of the shaft 19 in one direction causes rotation of the member 24 to provide successive speed positions of the controller, return movement of the member 24 being effected by a screw.therein which is engageable with a pin in the shaft. A dash-pot having a cylinder 33 and piston 37 is coupled through rod 38 to the member 24, the rod having a longitudinal bore with a transverse opening 45 controlled by a nut 46 and resilient insert 47. The downward movement of the piston 37, and the rate at which the member 24 rotates to successive speed positions, is thereby regulated by means of the nut 46, so that, if an attempt is made to advance the controller too rapidly, the shaft 19 winds the spring 27 and the energy thus stored is effective thereafter to advance the controller at a predetermined rate. The switches 49, actuated by the member 24 have depressible actuating buttons 50 passing through slots 55 in a plate 51 upon which the switches are mounted. A bracket 57 attached to the plate 51 carries the pivoted actuating levers 58 for each of the switches, these levers being spring-biased to depress the push-buttons 50. When cams 61 on the member 24 engage rollers 62 on the levers 58, the switch buttons are released. In the neutral position of the controller, the cams 61 hold the levers 58 away from the switch buttons 50, advancing movement of the controller causing the spring-actuated levers to depress the push-buttons.

Patent GB-395760-A (GB)
Title: Improvements in or relating to the roasting of plumbiferous sulphide ores
IPC: C22B13/02
Filed: 1932-01-23
Abstract: In the recovery of lead sulphide from sulphide ores such as pyrites containing small amounts of lead, the ore is roasted with a limited supply of air or oxygen-containing gas in a rotary or shaft kiln or mechanical furnace so that the oxygen is entirely used up, and a portion of the heated material is in contact with gas free from oxygen.  An oxygen-free gas, such as nitrogen or sulphur dioxide or a mixture thereof is introduced into the furnace in sufficient quantity and at such velocity, e.g. about 20 cms./sec, to volatilize and remove the lead sulphide as vapour. The exit gases are cooled, say to 400 DEG  C. and the sulphide precipitated for example, in an electrostatic dust precipitator. The charge may be admixed with coke or other carbonaceous matter, whereby free sulphur may be evolved, being condensed after removal of the lead sulphide.  The gases so obtained after removal of excess nitrogen are preferably employed as the oxygen-free gas, being introduced wholly or in part into the combustion zone or with the oxygen-containing gases, and serving to control the temperature of the combustion zone to about 800-900 DEG C. in the manner disclosed in Specification 359,478.  Where necessary, the inert gases and air are preheated.  The process may be combined with the sulphatization of zinc and copper in sulphide ores, as described in Specification 394,650.  Specification 391,136 also is referred to.

Title: Means for regulating and starting thermal power plants
IPC: F02C9/24
Filed: 1938-01-25
Abstract: 488,538. Elastic - fluid turbines. AKT.-GES. FUR TECHNISCHE STUDIEN. Jan. 25, 1938, No. 2399. Convention date, Jan. 26, 1937. [Class 110 (iii)] A power plant, operated by a gaseous medium, preferably air, working in a closed cycle at a pressure higher than atmospheric, has a furnace 1 supplying hot compressed air to a turbine 2 which drives a compresser 3 and exhausts into a turbine 5 giving external power. The exhaust of this latter turbine passes through a heat-exchanger 8 which heats the precompressed air before it passes to the heater 1. To facilitate regulating and starting the plant, a pipe 14 in which a cooler 16 and throttling valve 15 are located is branched off from the connecting pipe 13 in front of the turbine 5, and a throttling valve 19 inserted in the line 13. The pipe 14 is re-connected to another part of the closed circuit. If the load on the generator 6 suddenly falls, the machine 5 will speed up and the governor 17 will begin to close valve 19 and open valve 15 and gas instead of passing through the machine 5 will byepass it and cause it to slow up. If the period of low load is of long duration working fluid may be drawn off at valve 22, its density and pressure will then fall and the byepass may then be closed. A subsequent increase in load may be met by fresh working fluid from the accumulator 21. The cooler 16 is used to break down some of the pressure drop across the valve 15 as well as to cool the gases so that they do not pass into the heat-exchanger at too high a temperature. The quantity of cooling medium passing through the cooler 16 may be varied in accordance with the flow of working fluid through the byepass. A cooler 11 may be inserted in the circuit to cool the exhaust gases before they return to the compresser. The invention is not limited to a single power producing turbine. The motor 20 is used to run the turbines 2, 5 at low speed during the starting period.
