Title: Improvements relating to the heating and ventilation of vehicles
IPC: B60H1/00
Filed: 1950-09-28
Abstract: 678,343. Batteries. DAIMLER-BENZ AKT.-GES. Sept. 28, 1950 [Sept. 28, 1949], No. 23823/50. Class 53. [Also in Groups X and XIII] An electrical battery k, in a vehicle having a heating and ventilating installation, is heated when the interior of the vehicle is being heated and is cooled when the interior is being ventilated without being heated. Fresh air is caused by the motion of the vehicle to enter a passage a and branch therefrom into two passages b, c before re-uniting in a passage d which opens into the space around the driver's feet. Engine coolant flows through a heater e in the passage c to heat the air therein. A flap valve m at the branching point of the passages b, c or, as shown, at the junction of the passages, allows hot air, cold air or a mixture of both to flow into the passage d and into a narrow passage i conducting air over the battery k of the vehicle to discharge into the open air. Controlling flaps n, o may be provided in the passages d, i. The flap o may be controlled by the temperature of the battery, in which case the controls of the flaps m and o may be made interdependent to allow for seasonal conditions. The air may be heated electrically and other parts or apparatus on the vehicle may be heated or cooled. Defrosting nozzles for the windscreen may be connected to the passage d.

Title: Machine for grinding and polishing glass
IPC: B24B7/24
Filed: 1924-10-08
Abstract: 236,777. Schonholz, G. Oct. 8, 1924. No Patent granted (Sealing fee not paid). Flat extended surfaces, surfacing and polishing.-Near the corners of a triangular frame a three shafts b - - d are journaled and carry wheels j - - h for coarse and fine grinding and polishing, the shaft b being driven by, ior example, an electromotor i and belt k and shafts c, d from the shaft b. The water-boxes s, t, v, lined with zinc, are arranged so that a triangle is formed by their inner sides, which triangle has a cover w impermeable to water, while the walls y cover the outside of the frame a. With this arrangement all three wheels may be used at once, the felt disc necessary at the end of the operation being mounted on the polishing disc. In use, the glass sheet is roughly ground on disc f and then passed over disc g for fine grinding, the polishing being done on wheel h which may have a felt disc for repolishing, if necessary.
Patent GB-900642-A (GB)
Title: Process for the purification of beet sugar juice
IPC: C13B20/14
Filed: 1958-07-24
Abstract: Contaminating salts are removed from beet sugar juice which has already been partly purified, e.g. by coagulation using carbon dioxide, or by contact with a chlorine type strongly basic anion exchange resin, by first passing the juice through a column containing a mixed hydrogen type of weakly acidic cation exchange resin and an hydroxyl type of weakly or medium basic anion exchange resin, and then through a second column differing from the first only in that a strongly basic resin is used as the anion exchanger.  For regeneration the columns are backwashed to separate the resins with the sugar juice being purified or a juice of the same concentration, either being adjusted in concentration if necessary, and the strongly basic resin is then treated with caustic soda solution which may be stored, and used for the same resin after a further purification, or used to regenerate the weakly or medium basic resin, fresh caustic soda solution being added to it, if necessary.  The cation resins are treated with mineral acid, e.g. HCl or H2So4.  Preferred cationic resins are copolymers of methacrylic acid and divinyl benzene having carbonyl groups and suitable weakly or medium basic anion exchange resins have a primary secondary or tertiary amino group; the strongly basic resin is preferably a polystyrene/quaternary ammonium base-type resin.

Filed: 1959-07-13
Abstract: 861,203. Control of D.C. motors. CANADIAN WESTINGHOUSE CO. Ltd. July 13, 1959 [Aug. 29, 1958], No. 23959/59. Class 38 (3). [Also in Group XXXV] An exciter 10 for a Ward Leonard generator 5 has a field winding 11 which ensures that the voltage of the generator increases to the value set by a pattern field winding 15, whilst a compensating winding 12 corrects the IR-drop in the loop circuit. Current-limiting windings 13, 14 are supplied from magnetic amplifiers 16, 17, each amplifier being active for one direction of rotation of motor 1. The amplifier 16 has a bias winding 24, a control winding 27 energized in accordance with the motor current, and a control winding 28 which is excited when the motor voltage exceeds a predetermined value. In this manner, the maximum motor current is held at a constant value until the voltage reaches a given value, whereupon the current is reduced by the same factor at which the voltage increases so that the load on the motor is kept constant. The winding 28 is energized when the voltage from rectifier 29 exceeds that from bias potentiometer 32, and, by adjustment of resistor 30 and suitable choice of other components, the power can be held constant for the remainder of the programme. In another arrangement, the winding 28, and the corresponding winding on the magnetic amplifier 17, are supplied from two magnetic amplifiers each having a bias winding and a control winding responsive to the motor voltage, Fig. 2 (not shown).

Title: Improvements in and relating to the treatment of cellulosic materials
IPC: C12M1/107
Filed: 1930-08-13
Abstract: A combustible gas containing methane is produced by submitting fibrous cellulosic materials of the nature of corn stalks, bagasse and the like to the action of anaerobic and/or aerobic bacteria found in sewage sludge or to cultures of the same, the action being terminated when the more readily decomposed portions of the cellulosic material have been destroyed.  The cellulosic material may be given a pretreatment with hot water or with hot dilute acids such as dilute sulphuric acid or lime water.  Excessive foaming during the fermentation is prevented by introducing liquid drawn from a lower point in the vat on to the surface of the liquid in the vat.

Title: Improvements in or relating to centrifugal separating machines
IPC: B04B11/04
Filed: 1925-10-01
Abstract: 257,422. Sturgeon, R. A. Oct. 1, 1925. Density separators; discharging.-In a separator of the type having axially disposed nested cones the separated solids are discharged by utilizing the axial pressure of a column of water, or other clear liquid, due to the rotation of the apparatus. The hollow shaft a is rotated by means of the gearing C, D and carries two discs e, f which act as pistons in the rotary casing L, L<1>. Between the disc e and the top cover g are arranged the nested cones h, and the liquor to be treated is brought to the cones by the tube 0 from a feed tank N after passing through the grid O<1>. The part of the hollow shaft a traversed by the liquor has a spiral vane k<1>. Discs f<1>, f<2> are provided above and below the piston disc f; the two spaces between the discs are connected with the hollow shaft, one above the disc f and the other below it. A ring m normally covers holes n in the casing and is arranged above a disc o having a sleeve extension which slides on the sleeve of the disc f<2>. The machine is shown with the parts in position for separator working. The liquor is supplied from the feed tank N to the separator, and the purified liquid is discharged through the outlets t to the chamber E with discharge pipe J. The solids are deposited on the wall L of the drum and when the desired thickness of deposit is reached, the liquor feed is cut off. Water is then supplied through the pipe Q to the space below the piston f. When the radial depth of the annular column of water below the piston substantially exceeds that above the piston, the cylinder L, L<1> will descend. The surface liquor in the separator will then escape through the slots u and chamber F, and the solids will be discharged by centrifugal force into the chamber G from which they are collected through the openings M.. The water above the piston f flows over the lip g and escapes through the holes v. The cylinder L, L<1> travels downward until the collar p raises the disc o and the valve ring m to allow the water used in discharge to escape through the holes n. To raise the cylinder again to form the closed drum, water is supplied through the pipe P to the space above the piston f, where it forms a vertical annular wall to the depth of the lip q. The pressure in this annular column closes the joint r and the apparatus is ready for a further supply of liquor. The cycle of operations may be repeated indefinitely without stopping the rotation of the machine. Specification 24038/13 is referred to.
