Title: Improvements in or relating to the manufacture of gramophone recording blanks
Inventor: WOOLER JOHN
IPC: B29D17/00
Filed: 1954-03-17
Abstract: In a method of manufacturing gramophone recording blanks in the form of cores coated with a layer of material in which sound may be recorded by cutting a groove therein, the uncoated cores are fed in spaced relationship to a coating device and then transferred to a drying device so that adjacent coated cores remain spaced from each other.  Uncoated cores 15 of gramophone recording blanks are spaced by small rectangular members 16 on a band 1 which conveys the cores to a lacquering device 13, the band being unwound from a reel 2 on to a reel 3 after passing over supporting plate 5 and between driving rollers 7, 8.  The roller 8 is driven by a motor 10 which also drives the reel 3.  The members 16 are removed from the band after the cores have been coated by a scraper and excess coating is removed from the band by a scraper 16a and is collected in a shoot 17.  The cores are transferred by intermittently driven cams 18 on to supports 31 which are fed along a channel 36 from a band 33 running in a channel 32 to beneath the cores by an electromagnetic device 35 as described in Specification 645,053.  The cams 18 and device 35 are synchronized by the coated cores interrupting a light beam impinging on a photo-electric cell 17 and thereby operating a relay 40 controlling the operation of the cams and devices 38. The supports 31 ascend a ramp 25 on a band 22 where they contact the cores and then pass on the band over a plate 26 which leads to a drying device having an endless band 27 supporting the band 22. The band is driven from the motor <PICT:0781873/III/1> <PICT:0781873/III/2> 10.  The bands 1 and 22 may be driven at the same speed or the band 22 may be driven slightly more slowly.  To assist the ascent of the cores up the ramp 25 the cores may be made of magnetic material and a magnet placed below the ramp.  The other side of the core may be similarly treated to produce a double-sided gramophone record.

Title: Improvements in or relating to the determination and control of the content of a given chemical characteristic in a material
IPC: G05D21/02
Filed: 1941-07-03
Abstract: 561,733. Automatic control systems. WALLACE & TIERNAN PRODUCTS, Inc. July 3, 1941, No. 8422. Convention date, Aug. 3, 1940. [Class 38 (iv)] [Also in Groups III and XXXVIII] The amount of a constituent in a liquid is determined and/or controlled by dividing a sample into two portions, removing all of the constituent from one portion, adding to it a known amount of the constituent, and comparing it with the other portion. The comparing device may actuate means for varying the known addition of constituent until the two portions are identical, the known addition being then equal to the content in the original sample. Alternatively the comparing device may actuate means for controlling the addition of a reagent to the body of liquid from which the sample is taken. The invention is particularly applicable to the chlorination of water, sewage &c. According to Fig. 1, the samples are compared in a cell 5 with mercury electrodes 7, 24. The untreated portion is fed direct to the compartment 9 and the other portion after dechlorination in an absorber 12 containing active charcoal is supplied with chlorine generated in an electrolytic cell 26 and fed to the compartment 23. Suitable comparing cells are described in Specifications 548,173, 548,174, [both in Group XXXVI], 548,186 and 557,612. The chlorine generator 26 is operated by current derived from a transformer 33 and rectifier 34, controlled by a variable resistance 36, and is in series with a recording galvanometer 35. The current generated in the comparing cell 5 controls the variable resistance 36 by means of a relay 37, the output of which after amplification in an eletronic amplifier 45 (e.g. as described in Specification 493,457, [Group XXXVIII]) is passed through the oppositely wound shading coils 47 of the servomotor 42, which in order to prevent hunting is switched on intermittently by rotating cam 53. The chlorine supplied by generator 26 is thus brought to equivalence with the content of the untreated sample and is measured on the recorder 35. The latter may also actuate valve 160 controlling the supply of chlorine to the main body of water flowing in the conduit. In a modification, the dechlorinated portion of the sample is mixed with chlorine solution supplied by a pump driven, by a motor with infinitely variable gear, which is controlled by the current generated in the comparing cell, and in further modifications the supply of solution is controlled by varying the head.
