Title: Photographic Viewfinder.
IPC: G02B23/14
Filed: 1967-03-09
Abstract: 1,176,005. Viewfinders: optical apparatus. VOIGTL€NDER A.G. March 9, 1967[March 12, 1966], No. 11098/67. Headings G2A and G2J. The frame mark 11 of an Albada viewfinder is illuminated by light incident on the area surrounding the viewfinder objective lens, the light being transmitted from that area by a plurality of light guides. As shown in Fig. 1 light is transmitted to each side of the rectangular frame mark 11 by a series of glass rods 7 which abut one side of a block 5 carrying the partially transmitting concave mirror 6. The frame mark 11 is formed by fully reflective prisms 10 embedded in a triangleshaped body 9 which incorporates the eye-piece 8. The ends of the rods 7 adjacent the mark 11 are joined to the body 9. Each series of rods 7 may be replaced by a single light-conducting plate. In Fig. 5 two plates 17c, 17d which transmit light to the horizontal sides of the frame mark 11 are laterally off-set with respect to the viewfinder objective in order to reduce the height of the viewfinder. The light conducting rods 7 may be circular, oval or polygonal in cross-section and may have substantially line contact with each other, to form single or multi-layer plate elements.
Patent GB-670986-A (GB)
Title: Improvements in and relating to the production of penicillin
Filed: 1949-04-26
Abstract: Penicillin is manufactured by cultivating penicillin - producing micro - organisms in a nutrient containing an ester of phenylacetic acid with an amino alcohol containing tertiary linked nitrogen (which may be part of a ring, e.g. a piperidine ring). In an example, Penicillin notatum/chrysogenum is cultivated in a medium containing corn steep liquor, lactose, calcium carbonate and the diethylaminoethyl ester of phenylacetic acid.  The Specification as open to inspection under Sect. 91 comprises also the use of esters of phenylacetic acid with amino alcohols containing primary or secondary linked nitrogen, which substances should, however, be added by degrees on account of their toxicity to the microorganisms in high concentrations.  This subject-matter does not appear in the Specification as accepted.

Title: Control apparatus for controlling electrical heaters
IPC: B29C45/78
Filed: 1975-06-13
Abstract: 1467180 Control of electrical heaters in a moulding machine EASTHOLM ELECTRONICS Ltd 13 June 1975 [13 March 1974] 11164/74 Heading H2H Heaters 2a, 2b, 2c, located in respective inlets (3) to three mould cavities (1) of a plastics injection moulding machine, Fig. 1 (not shown), are supplied from an A.C. source LN through respective circuit breakers 23a, 23b, 23c, changeover switches 26a, 26b, 26c, on/off switches 9 and triacs 6, each triac being controlled by a respective trigger circuit 8 and diac 7 whereby the current through each heater is adjustable according to the setting of a potentiometer 10 in its trigger circuit 8. Progressive increase in the resistance of the potentiometer produces corresponding increase in the angle at which the triac is fired in each half-cycle of the supply LN, Fig. 3 (not shown), to progressively decrease the heater current, the potentiometer setting providing an indication of the heater temperature if such sensing and indicating means is not provided adjacent to the heaters. Closure of a switch 11 provides maximum heater current at starting, members 18, 19 having been preset to produce a desired operating range of potentiometer 10. Changeover of any one of switches 26a, 26b, 26c enables the current through the corresponding heater to be indicated by an ammeter 24. A heater can be tested by opening its switch 9, removing it from sockets 5 and connecting it to the sockets 28 of a testing device 27 whose ammeter 30, previously reading full scale by adjustment of a potentiometer 29, then reads full scale, zero or intermediate according to whether the heater is short or opencircuited or in order. An earth fault is indicated by any reading other than zero when a switch 31 is opened.

Title: Improvements in thermostatic mixing valves
IPC: G05D23/13
Filed: 1945-05-03
Abstract: 591,214. Thermally controlled mixing valves. GUMMERS, Ltd., and ELLIS, A. E. May 3,1945, No. 11237. [Class 135] A valve for mixing hot and cold water for domestic purposes comprises a casing having hot and cold water inlets 16, 15 respectively and a mixing chamber 12 with an outlet 14, the admission of cold water being regulated by a valve 51 coacting with a venturi tube 50 and of hot water by a thermally-controlled plunger valve 25 which regulates the flow of hot water through the radial ports in a replaceable sleeve 18. The initial setting of the valve 25 is effected by a rotatable cap 37 the spindle 36 of which engages by means of a cross-pin 54 with a slot in the upper end of the threaded spindle 31 of the valve. Variations in the position of the valve are effected by the thermostatic elements 34 the free ends of which engage a collar 33 on the spindle 31. The valve may be closed by adjusting the cap 37 until the packings in the flange 28 of the valve 25 seal the upper ends of the venturi tube and the sleeve 18. Steam may be mixed with the cold water instead of hot water in which case the steam is admitted at the inlet 15. In a modification, a conical nozzle is substituted for the venturi tube, and the flow of cold water into the lower and larger end thereof is controlled by a spring- loaded conical valve the position of which is regulated by a pin projecting from the underside of the flange 28 of the plunger valves.

Title: Improvements in hollow drill steel
IPC: B23K20/00
Filed: 1927-04-27
Abstract: 275,560. Pryce, L. Aug. 9, 1926, [Convention date]. Tubes; cased forms.-Hollow rock drill steel is made by casting a steel ingot or billet round a tubular core of non-corroding ferrous alloy such as a chromium alloy and then reducing to form the drill steel, the tubular core forming a lining to reduce the corrosion effects produced by water during drilling. The Specification as open to inspection under Sect. 91 (3) (a) states that the lining may consist of pure iron, non-corroding metals such as nickel, and non-corroding ferrous alloys such as aluminium alloys. The lining may also be applied by electroplating prior to rolling the blank. A lining of pure iron may also be derived from the steel itself by chemical treatment or by de-carbonizing with a current of air or oxygen. This subject-matter does not appear in the Specification as accepted.

Filed: 1922-04-21
Abstract: 182,441. Akt.-Ges. der Maschinenfabriken Escher, Wyss, et Cie. June 28, 1921, [Convention date]. Stuffing-boxes, substitutes for; with packing- device acting when apparatus is at rest.-Leakage of fluid from the rotary compressor of a refrigerating plant &c. when at rest is prevented by compressible packing, the pressure on which is relieved when the apparatus is rotating. In one arrangement a screw cap on the end of an ordinary packing-box is rotated by a handlever to compress packing between the cap and the end of the box and a collar on the shaft. The packing during running is effected by a labyrinth device 1 supplied with fluid by a passage 2. While the apparatus is stationary, compressible packing 5 is acted on by a gland 6 pressed by a spring 13. When the apparatus is rotating the gland is withdrawn by centrifugal weights 11, connected by links 12 to a collar 8 on the shaft and a ring 7 surrounding the gland 6. In a modification, Fig. 3, when the apparatus is at rest a collar 28 on the shaft is pressed against a packing 27 carried by the packing-box by the axial thrust of the fluid in the compressor 23. When the apparatus is running the pressure on the packing 27 is relieved, the thrust of the fluid in the compressor being balanced by the pressure of lubricant admitted by passages 31 to the thrust bearing 29.

The journal bearings are formed by allowing the required clearance between the shaft 15 and hubs 34 so that the pressurized gas can flow therebetween. The gas, which enters through apertures 41, is pressurized by oblique grooves 53 or the like in radial faces 22 of the plate 18 and flows through the journal bearings where it escapes to atmosphere. The escaping gas also forms a seal for the bearings. Electricity is supplied through wires extending via bores of the shaft 15 to a winding 26 which passes through windows 19 in the plate 18. The self-generating grooves may be on the flanges 38 of the members 30, 31. A complete stator may be provided on each side of the plate 18. In Fig. 6 (not shown), the motor is gimbal-mounted.
