Title: Improvements in temperature regulating devices
IPC: G05D23/12
Filed: 1924-06-17
Abstract: 236,716. Beacham, T. E. June 17, 1924. Thermostats.-Relates to temperature-regulating apparatus of the kind in which there is arranged in chamber 3, the temperature of which is to be controlled, a closed vessel 2 containing a gas or volatile liquid which, by its expansion, displaces another fluid, such as mercury, into an external vessel 7 containing a float, piston, or diaphragm operating a valve or electric switch for regulating the heating or cooling means. In order to prevent mixing of the gas or volatile liquid with the other liquid, or loss thereof into the external vessel, the passage 10 connecting the vessels is provided with a reduced, capillary, or labyrinthal portion such as that indicated at 95, Fig. 1, in which is shown an intermediate vessel 9 interposed between the vessels 2, 7. In this construction a steam supply valve 5 mounted on a spindle 15 is controlled by a float 6, and a valve 11 is adapted to close the passage 8 between the vessels 7, 9 when the apparatus is transported. In a modification, Figs. 2 and 3, the three vessels 2, 7, 9 are arranged as a unit and the lower end of the pipe 10 extends into the vessel 9 where it is formed with a number of convolutions 12, 13, 14 arranged in three planes mutually at right-angles. A sliding piston 6 controls the operation of a valve or switch through the intermediary of a lever 16. Further modifications are described in which the pipe 10 may have an external coiled portion in addition to the convolutions 12, 13, 14: in which the valve is moved to a completely open or completely closed position by means of a weight; in which the float or piston is replaced bv a diaphragm separated from the mercury by a layer of water; and in which the capillary passages are formed in blocks arranged in the vessel 9. In a still further modification, Fig. 9, a mercury container 61 with contacts 62, 63 is mounted on the vessel 9, which is pivotally supported so as to form a rocking switch for regulating the heating current. The vessel 9 is formed at its ends with chambers 58, 59 containing mercury, the chamber 58 communicating with the pipe 10 and having the mercury displaced therefrom through a tube 60 into the chamber 59 when an expansion of fluid occurs in the vessel 2. When a gas is employed in the vessel 2 a separating liquid such as glycerine is disposed in the passage 10 and in the space above the liquid in the external vessel.

Title: Manufacture of solid diazo-salts
Filed: 1933-05-22
Abstract: Solid diazo salts are made by mono-diazotising a halogenated p-phenylenediamine (no SO3H or COOH groups) and separating the monodiazo compound in the form of a solid, mineral acid salt or stabilised salt, according to known methods.  They are suitable for use in the icecolour process.  In examples the 2 : 5- and 2 : 6-dichloro, 2 : 6-dibromo, 2-chloro-5-methyl, 2 - chloro-, 2 - chloro - 6 - bromo - and 2 - bromo - derivatives of p-phenylenediamine are monodiazotised and the diazonium compounds precipitated either as (1) the chloride, (2) the sulphate, (3) zinc or cadmium chloride double salt, (4) fluoborate, (5) 1 : 5- or 2 : 6-naphthalene disulphonate, (6) p-chlorobenzene-sulphonate, 4 - chlortoluene - 3 - sulphonate, benzene - 1 : 3 - disulphonate, 1-chlorbenzene-2 : 4-disulphonate or a -naphthalene sulphonate or (7) as tin double salt by addition of SnCl4 or Na2SnCl6.  The diazotisation may be carried out in the presence of organic liquids, e.g. glacial acetic acid, benzene or carbon tetrachloride using amyl or ethylnitrite, the diamine monosulphate being the starting material.  The diazo salts may be mixed with diluents e.g. sodium sulphate or partly dehydrated aluminium sulphate.

Patent GB-599743-A (GB)
Title: Automatic phonograph
IPC: G11B17/16
Filed: 1945-06-12
Abstract: 599,743. Magazine gramophones. THIGGS, W. W. (Farnsworth Television & Radio Corporation). June 12, 1945, No. 14894. [Class 40 (ii)] In a magazine gramophone of the type in which records are stored above the turntable on diametrically opposite supports, the said supports are of unequal height and have sliding members which alternately displace the lowermost record in opposite horizontal directions to effect disengagement from the shelves of the supports, after which it is received by an elevating member which lowers the record to a horizontal position and then releases it on to the turntable. During a record-changing cycle, controlled by a cycling cam-disc 120, the slidable member 53 of the support 34, Fig. 5, moves inwards to displace the edge of the lowermost record from the fixed shelf 37A so that it falls on to a secondary shelf 55 which is fixed to the slidable member 53. Immediately afterwards a slidable member 87 (or 88 when records of the larger size are in use) of the support 35 moves inwards to displace the other edge of the record from the shelf 38A (or 38B) so that it falls on to a member 91, which meanwhile has taken up the position shown in Fig. 6, but which is almost immediately lowered again so that the hole in the centre of the record engages the conical tip 45 of the turntable spindle 44. Almost immediately the secondary shaft 55 is completely withdrawn so that the edge of the record leaves the secondary shelf 55. At the same time, the supporting member 91, influenced by the groove 97 in the post 92, swings clear of the record and allows it to drop on to the turntable 15, Fig. 7. Provision for records of alternative size is made by a manual control which causes the support 35 to be rotated 90 degrees, the support 34 moved inwards or outwards by an appropriate amount, and the pick-up arm starting point modified, as described with reference to Fig. 4 (not shown). Details are also given of the pick-up arm control and automatic initiation mechanism which is operated by the quickening of the pick-up traverse at the run-off groove. Driving is effected by a friction-pulley in contact with the inner part of the turntable rim.
