Title: Improvements in or relating to discharge apparatus of the piston and cylinder type
IPC: F16N25/02
Filed: 1937-11-03
Abstract: 505,248. Pump distributing-apparatus; liquid-pressure engines. TRIER BROS., Ltd., TRIER, F. N., and CROTHERS, P. F. Nov. 3, 1937, Nos. 30101 /37, 8872/38, and 23571/38. [Class 102 (i)] [Also in Groups, XXIX and XXXIV] Apparatus for distributing lubricant, or other liquid or semi-liquid substance, comprises two similar main cylinders each divided by a free piston into two chambers, one chamber having inlet and delivery passages for the lubricant, the other chamber having pump apparatus for alternately delivering and withdrawing operating liquid, and valve apparatus, actuated by variations in pressure, for causing automatic reversal of flow of the operating liquid when further movement of the free piston, in the main cylinder to which operating liquid is being delivered, is prevented. The two main cylinders A<1>, A<2>, Figs: 1 and 2, with floating pistons A<8>, A<4>, act alternately, and the discharge of lubricant is made substantially continuous, by using a single pump comprising a plunger A<6> in a cylinder A<5>, the delivery of which is controlled by means of a dummy piston F, Fig. 5. The position of rest of the piston F is determined by its head F<3> engaging a flange F<4> on a slidable housing F<5> controlled by a screw F<2>. In a modification, an immovable abutment is provided for the piston F when it has just uncovered the delivery port E<3>. The delivery pipes B, B<1> from the cylinders A', A<2> may be connected with measuring and distributing devices C; Figs. 1 and 10, each comprising a shuttle type distributing valve C<4> in a bore C<3> and a double-ended plunger C‹ in a bore C<5>. The bores C', C' are connected by ports H<2> ... H<5>, whilst the bore C' is connected to the delivery pipes B, B<1>, and, by means of ports H, H' to pipes C<1>, C<2> leading to the apparatus to be lubricated. The stroke of the-plunger C<6> is controlled by stops C', either or both of which may be adjusted as by means of washers C <8>. The centre part of each plunger C<6> is made visible by means of an opening in the casing C, and at the end of each stroke the plungers C<6> may close an electric circuit and operate an indicator in the form of one or more lamps. The automatic reversal device D, Figs. 6 and 7, comprises a shuttle valve J and a releasing plunger K connected by two unidirectional friction locks L, L<1> acting in opposite directions, and delivery and suction passages E<4>, E<5> connected alternately to passages G, G<1> communicating with the lower ends of the cylinders A<1>, A<2>. The pressure at which the plunger K is released is indicated by gauges M<7> and is controlled by a valve M<3> adjusted by a setting device M<5>, and a snap action movement of the valve J is produced by means of a pressure accumulator N in communication with each end of its cylinder. A sight feed E<2> is provided on the suction passage E<5>.

Title: Improvements in or relating to heterodyne receivers, suitable for use for wireless and other high frequency reception
IPC: H03J3/28
Filed: 1931-10-30
Abstract: 372,692. Valve amplifying and detecting circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Roberts, W. van B., 155, Hodge Road, Princeton, New Jersey, U.S.A.) Oct. 30, 1931, No. 30120. Convention date, Oct. 30, 1930. [Class 40 (v).] To facilitate the ganging of the tuning of a supersonic heterodyne receiver the oscillator 5 is tuned to the signal and the required difference frequency is produced by an auxiliary oscillator 6 tuned to the intermediate frequency, and only one of the side frequencies produced by modulation is used to beat with the signal frequency. The auxiliary modulating oscillator 6 is connected in parallel to the oscillator 5 through a choke 16 and a filter F is interposed in the coupling C of the detector 2 to the oscillators to suppress one of the beat frequencies produced. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which the filter F is omitted, in which case the two oscillator voltages applied produce two beat frequencies which, if unequal, give audible beats in the final detector so that for receiving telegraphy a second heterodyne is unnecessary. For telephony the oscillator 5 must be maintained exactly synchronous with the carrier frequency with thi.s modification. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in and relating to thermostats
IPC: G05D23/12
Filed: 1936-11-05
Abstract: 486,659. Thermostats. GAUL, M., and GOLDSCHMIDT, M. Nov. 5, 1936, No. 30190. [Class 135] In thermostats, the thermostatic element is carried on a rod provided with quick-pitch screw threads so that when the element expands axially it is rotated to operate the valve or valves. The element 6, Figs. 1 and 2, is secured on a divided rod 10 which engages at one end a plain stud 11 on the casing 1 and is threaded at the other end to engage a quick-threaded bolt 12 secured to the casing. When the element expands, the rod 10 moves axially and is rotated, carrying with it the valve member 4 which thus alternatively closes the radiator port 2 and the short-circuit port 3 to the engine port x. In Fig. 6, the rod 10 lies axially in the casing 1 and engages a stationary nut 13, the valve 4 being formed as a swashing plate on the rod and engaging only with inclined projections 20 on the casing to reduce friction. In Fig. 3, two valve plates 4, 5 with sector-shaped orifices co-operating with similar orifices 2, 3 in the casing are used. The lower end of the rod 10 is screwed to engage a nut 16 in the casing to raise and lower the plate 5 and produce an additive effect on the movement of the plate 4, the plates only engaging with the casing at the ends of their movements.

Title: Improvements in and relating to accelerometers
Inventor: BEDFORD LESLIE HERBERT
IPC: G01P15/10
Filed: 1956-10-03
Abstract: 896,101. Measuring acceleration electrically. ENGLISH ELECTRIC CO. Ltd. Sept. 27, 1957 [Oct. 3, 1956], No. 30198/56. Drawings to Specification. Class 40 (1). In an accelerometer a mass is supported in a framework by several tensioned, vibrating strings. Upon acceleration of the framework, the inertial forces due to the acceleration of the mass, after the string tensions and the resultant vibration frequency changes are a measure of the acceleration. The strings are maintained in vibration by exciter units and the vibrations are detected at pick-offs which provide electrical signals. It is shown that if the sum of the frequencies is maintained constant, the difference frequency is in a linear relationship with the acceleration. This is effected by a feed-back loop which detects the sum of the frequencies and applies a control to the strings to maintain the sum at a fixed value, by changing the tension in the strings by heating, as described in Specification 896,102. Strings are employed having a ratio of natural frequencies which differs slightly from a simple ratio in order to compensate for second-order terms in the accelerometer characteristics.

Title: New phthalocyanine dyestuffs containing epoxide or alpha-beta-halogenhydrin groups and process for their manufacture
IPC: C09B62/60
Filed: 1958-09-23
Abstract: The invention comprises phthalocyanine dyes which contain at least one sulphonic acid group and at least one epoxy or a  : b -halohydrin group linked to the dye molecule via an amino bridge.  They are prepared by reacting a phthalocyanine dye having at least one sulphonic acid group and at least one acylatable amino group with a compound capable of introducing an epoxy or a  : b -halohydrin group and if desired converting the halohydrin group into an epoxy group. The acylatable amino group may be attached to an aromatic nucleus or alkylene chain which is linked to the dye molecule, for example, through a keto, sulphone, carbonamide, sulphonamide or sulphonic acid ester group. Preferred phthalocyanines are the iron, cobalt, nickel, copper and zinc phthalocyanine sulphonic acids.  Specified compounds introducing epoxy or halohydrin groups include glycerola -monochlorohydrin, glycerol-a  : g - or -a  : b -dichlorohydrins, epichlorhydrin, butadiene dioxide and diglycidyl ethers.  The dyes may be used to colour wool, nylon, polyvinyl alcohol, and preferably cellulose materials such as cotton, rayon and paper, in blue shades. The dyeings on cellulose materials are fixed by heating in the presence of an acid-binding agent.  In Examples (1) copper phthalocyanine-3 : 41 : 411 : 4111-tetrasulphonic acid is converted, by the action of chlorosulphonic acid and thionyl chloride, to the sulphochloride which is reacted with less than its equivalent of p-formylamidoaniline, the product hydrolysed and finally reacted with epichlorhydrin; (2) copper phthalocyanine is reacted with chlorosulphonic acid and thionyl chloride to give a sulphochloride which is then treated as in (1); (3) as in (1) but reacting the sulphochloride with 1 : 3-diaminobenzene- 4sulphonic acid and treating the resultant sulphonamide with ammonia before reaction with epichlorhydrin; (4) copper phthalocyanine-3 : 31 : 311 : 3111- or -3 : 41 : 411 : 4111- or -4 : 41 : 411 : 4111- tetra-sulphochloride is reacted with monoacetyl-ethylenediamine, the N-acetyl and sulphochloride groups of the product are hydrolysed and epichlorhydrin is reacted with the mixture so obtained; (5) a copper phthalocyanine containing 2 sulphonic acid groups and 2 aminomethyl groups is reacted with epichlorhydrin.

Abstract: 1,262,796. Crimped viscose filaments. MITSUBISHI RAYON CO. Ltd. 23 June, 1970 [24 June, 1969], No. 30468/70. Heading B5B. A method for producing highly crimped regenerated cellulose fibres involves stretching filaments containing the reaction product of cellulose xanthate and formaldehyde in a non- aqueous liquid having a boiling point of at least 80‹ C. and maintained at a temperature of 60‹ to 150‹ C., preferably between 70‹ and 130‹ C.; relaxing said filaments having a regeneration degree of less than 89% and preferably between 20 and 80%, in solution having a swelling action on the filaments and maintained at a temperature of 30‹ to 90‹ C. and then subjecting the filaments to regeneration treatment to complete regeneration. The filaments are preferably obtained by extruding viscose containing 2 to 8% total alkali and having a salt point of at least 16 into a coagulation bath maintained at a temperature less than 45‹ C. containing 20 to 250 g./l. sodium sulphate, less than 0À3 g./l. zinc sulphate and a sulphuric acid concentration in the range 3A + 8 to 8A+ 16 g./l., A being the total alkali concentration (%) in the viscose. When formaldehyde is added to the viscose, preferably in amount of from 0À2 to 2% by weight based on the viscose, its concentration in the coagulation bath may be in the range 1 to 6 g./l. When it is absent from the viscose solution either the coagulation bath contains between 4 and 20 g./l. formaldehyde or after coagulation in a bath consisting of 14 to 50 g./l. sulphuric acid, 20 to 250 g./l. sodium sulphate and less than 1 g./l. zinc sulphate at a temperature below 35‹ C. the coagulated filaments are treated with an aqueous solution containing between 15 and 70 g./l. formaldehyde. Suitable non-aqueous solvents for the stretching process are liquid paraffins, silicone oil, white oil, glycerine, polyethylene glycol, xylene, toluene and styrene, the filaments being stretched at a ratio between 0À25 and 0À8 times their maximum stretch ratio. The relaxation step is preferably accomplished in aqueous solutions maintained at pH between 2À0 and 10À5, suitably in aqueous solutions containing either inorganic or organic salts of alkali or alkaline earth metals or organic N- and S-containing solvents, soluble ketones or cyclic ethers. In some of the examples the relaxation step is carried out after the filaments produced according to the above process have been cut into staple lengths.
