Patent GB-203668-A (GB)
IPC: G02B23/14
Filed: 1923-08-21
Abstract: 203,668. Zeiss, C. [Firm of]. Sept. 6, 1922, [Convention date]. Addition to 147,107. Finders.-Modified constructions are described of the finder described in the parent Specification. In one construction, Figs. 1 and 2, the sighting- mark frame c is shaped to correspond to the image field, and the central part b of the lens b is flattened or pierced to enable the object to be seen directly and at the same time as the frame c is seen through the rest of the lens. Alternatively the lens may be formed of flat discs d<1>, d<2>, d<3>, d<4>, Fig. 3, cemented together so as to form plane steps with spherical margins, the frame being viewed through the spherical parts and the object directly seen through the plane portions. In another construction, Figs. 5 and 6, a semi-transparent concave mirror f, is placed in front of the eye-piece g which has a sight hole g<1>, and a portion of the rear surface of the eyepiece corresponding to the image field is painted black and has a white margin. The mirror may be formed by lightly silvering, smoking, or colouring the glass, or by silvering in strips or gratings so that the transparent and reflecting portions alternate. In another construction, Fig. 7, the sighting marks formed by gaps in an opaque coating in the glass plate k are projected by the lens i and viewed by reflection from the grating-mirrored glass plate m through which the object is directly viewed.

Title: Continuous de-scaling apparatus for metal strip
IPC: C23G3/02

Abstract: 895,263. Cleaning metals. BETEILIGUNGSUND PATENTVERWALTUNGS GESELLSCHAFT. June 17, 1960 [June 18, 1959], No. 21458/60. Class 82(2). [Also in Group XXXV] Strip metal, e.g. steel, is de-scaled in an apparatus which comprises at least one acid immersion or acid spraying bath in which the strip hangs in a loop, driving means for the strip disposed either in advance of or beyond the bath, and a detector responsive to interception by the loop of a beam of light or radiation from radioactive material, or responsive to modification by the loop of an electric or magnetic field, for determining when the loop has descended into the bath to a predetermined level. As shown, strip 1 runs vertically through scale-breaker 2, driving rolls 4, acid immersion baths 5, 6, water spray section 22 and feed rollers 21. The depth of the loop in baths 5, 6 is determined by photocells 17-20 associated with light sources 16, and the photocells control the speed of rollers 4, 21 so as to maintain the lengths of the loops constant and hence the duration of immersion of the strip. Baths 5, 6 are in communication via conduit 26 and fresh or regenerated acid is fed to bath 6 through inlet 27.

Title: Improvements in and relating to malt extract syrup and the use thereof in brewing
IPC: C12C1/18
Filed: 1944-11-03
Abstract: Wort or mash from malt, preferably barley malt kilned at moderate temperature, is seeded with lactic acid bacteria, e.g., Lactobacillus delbrückii, and, when sufficiently acid, e.g., after 24 hours at 115 DEG F., is concentrated by evaporation to a syrup of not less than 75 per cent. solids and not less than 2 per cent., e.g., 4-5.5 per cent. of lactic acid.  Where a mash is employed, the acid wort is run from the mash residue before the concentration.  In brewing, there is added to the mash or wort, at the mashing stage or later, 2 per cent. or more (calculated on the malt used) of the syrup, which may be dissolved in water before addition.

Title: An improved method of treating lyes, containing copper and zinc
IPC: C22B3/00
Filed: 1929-07-13
Abstract: 329,225. Lenander, N. E., and Ryen, I. July 13, 1929. Precipitating.-Lyes containing copper and zinc, obtained for instance by leaching chloridized roasted pyrites, may, after treatment with sulphurous acid to reduce the copper to cuprous chloride, be further treated with finely divided metallic copper, preferably in the form of cement copper, which, if used in excess precipitates also any gold or silver present. To obtain copper in the metallic form the solution together with cuprous chloride may be treated with iron, or the cuprous chloride may be separated from the solution and then treated with iron, whereby a cement copper with a large percentage of silver is obtained. The cuprous chloride remaining in solution may be precipitated with iron.

Title: Meat boiler
IPC: A47J27/20
Filed: 1925-09-01
Abstract: 260,384. Lippert, R. Sept. 1, 1925. Heating and cooking vessels.-A device for cooking ham, sausage meat, &c. under pressure comprises a container having movable top and bottom plates adapted to be held in adjusted position by means of hooks engaging rack teeth. The lower plate 32 carries a bar 33 the upturned ends of which are formed with downwardlyinclined teeth 35, 36, adapted to be engaged by spring-urged hook members 37, 38. The cover plate 14 carries one element 15 of a telescopic socket enclosing a spring and supporting a plate 21 guided by rods 22, 23 ,depending from a handle member 24 the ends of which carry pivotally suspended spring-controlled rack members 27, 28 adapted to engage with teeth 12, 13 on the ends of the container. A conical member 45 attached to the handle 24 is interposed between it and the plate 21. In the simplified construction shown in Fig. 5 the cover plate is attached by means comprising a cranked bar 49 provided with pivotally suspended rack members 52, 53.

Title: Improvements in or relating to washing machines
IPC: D06F37/38
Filed: 1960-06-22
Abstract: 934,822. Control of A.C. motors; actuation of switches. SIEMENS-ELECTROGEVATE A.G. June 22, 1960 [June 22, 1959; Sept. 16, 1959], No. 21901/60; Classes 38 (3) and 38 (5). The lever 20 of a switch 19 for changing the direction of rotation of a motor which drives the agitator drum of a washing-machine is actuated by the ends 17, 18 of a spring band 16 secured on the periphery of an internally toothed wheel 10. A further toothed wheel 12 for engagement with the wheel 10 is mounted on an eccentric 8 of a wheel 6 which is friction driven by the hub portion 14 of a gear-wheel 15 mounted on the shaft of the drum of the machine. The toothed wheel 12 has a slot 13 which engages a pin 5. A rocking and vertical movement of the wheel 12 is produced by rotation of the friction drive wheel 6 and a step-by-step rotation of the toothed wheel 10 results. In a modification, Fig. 5 (not shown), the wheel 6 is gear driven. For delaying the switching on of the motor by the switch 19 a switch 27 may be provided which may be by-passed by a control switch 28, Fig. 7. To increase the length of time between operation of a change-over switch 36, thermal switches 37, 38 are used in the supply connections to the main and auxiliary phases 33, 34 of the motor, Fig. 8. Each switch has a high resistance heater winding 39 and, with the switch in its normal open position, the current through it is insufficient to start the motor. In a modification, Fig. 10 (not shown), each switch also comprises a low resistance winding which is connected across the high resistance winding when the switch closes. In Fig. 12, both thermal switches 51, 52 are normally closed and with the change-over switch 36 in the position a, the winding 53 of the motor is energized and the switch 52 is opened. The current through the resistance 56 is too small to cause switch 51 to open and the motor runs until the switch 36 is moved to b. Switch 52 being open, the motor then stops until, with no current flowing through resistance 57, the switch re-closes and the motor restarts with winding 54 energized. Switch 51 is then opened and causes interruption of the motor current when the switch is moved back to position a.

The construction provides an even illumination along the length of the main portion 10. A fluorescent coating (shown cross-hatched) may be extended over a substantial part of each side portion 12 so that the side portions contribute to the emission of light.
