IPC: G07F17/26
Filed: 1928-08-20
Abstract: 311,614. Ocur Metallbettenfabrik Ges. May 16, 1928, [Convention date]. Automatic a n d coin-freed apparatus; tell-tale apparatus.- An automatic weighing machine, of the kind wherein a record of the weight and date is produced upon a ticket, is combined with an automatic camera so that the weighed article or a characteristic portion of the same is photographed upon the ticket. As applied to a personal weighing machine, the insertion of a coin causes, by means of usual weighing mechanism, a cylinder 3 to rotate to an extent dependent on the weight on the platform 2. The cylinder has transparent weight numerals and contains an electric lamp 4. At one side is arranged a similar cylinder indicating the date and adapted for adjustment by hand or by clockwork. A camera 5 is mounted in the casing. A conveyer band 6 driven by an electric motor 10 is led past a magazine 7 of light-sensitive metal discs, through photographic baths 12, 13 and past a drying apparatus 14. In the operation of the machine, the conveyer band carries a disc 8 from the magazine 7 and holds it between the camera and the cylinder 3 sufficiently long to photograph the transparent numerals and the person standing on the machine, the person being illuminated by a lamp 9. The disc is then carried through the tanks 12, 13, past the drying apparatus 14, and is delivered to the trough 15, the weight and date being thus recorded on one side of the ticket and the photograph appearing on the other side. The weight and date may be printed or stamped on the disc and the photograph be made above these indications. Instead of a metal disc, a cardboard ticket cut from a strip may be used.

Title: Hydrostatic power transmission
Inventor: DOWTY GEORGE HERBERT
IPC: F16H61/42
Filed: 1962-06-22
Abstract: 978,603. Hydrostatic transmission. DOWTY TECHNICAL DEVELOPMENTS Ltd. June 10, 1963 [June 22, 1962; May 4, 1963], Nos. 24047/62 and 17724/63. Heading F2C. In a hydrostatic transmission comprising pump and motor units of the axial piston type with tilting heads, the units are interconnected for conjoint tilting movement by a linkage arrangement which may also provide the hydraulic connection between them. As shown, the pump and motor shafts 13, 14 are parallel and the motor 8 is disposed below the pump 4 within a casing 1. The pump and motor tilt about parallel horizontal trunnions 21, 43, the pump casing have a projecting portion 37 connected to the motor casing by parallel links 44, 45. These latter are of tubular construction to provide, in conjunction with passages 35, 36 in member 37, communication between the pump and motor. With the pump in the zero-delivery position shown the link pivots 54, 59 are arranged in line with the pump trunnions 21 so that the motor is in position for maximum displacement. Tilting is controlled by an hydraulic piston and cylinder unit 65, 66 connected to the pump easing by links 71, 72 and supplied with pressure liquid from the make-up gear pump 73. When the latter is inoperative the pump and motor are held in position by a latch consisting of a spring- loaded bolt 74 engaging a lug 75 on the pump casing, the bolt being retracted when the pump is functioning by pressure liquid supplied through a passage 75 to a piston 76 integral with the bolt. In other arrangements the pump and motor shafts are non-parallel, Fig. 5 (not shown), or the pump and motor are disposed laterally side by side, Figs. 7 and 8 (not shown), while in a further arrangement, Figs. 9-11 (not shown) the pump and motor are mounted very close to one another to form a more compact unit.
Patent GB-851108-A (GB)
Title: Catalytic conversion process
IPC: C01B32/40
Filed: 1959-07-14
Abstract: A vapour- or liquid-phase reaction between at least two feed materials in presence of a finely divided solid catalyst is conducted by continuously introducing into the conversion zone a first reactant whose rate of travel through this zone is less than that of a second reactant, periodically introducing pulses of the second reactant to the conversion zone and recovering the reaction products, the periods of time between the said pulses being sufficient to prevent the intermingling of the products of one pulse with the products of the next pulse.  In examples, HCl is oxidised to Cl2 using CuCl/pumice catalyst, and CO2 reduced with H2 to CO using Fe/ceria/kieselguhr catalyst. The catalytic partial oxidation of benzene and naphthalene is also mentioned.

Title: Improvements in or relating to television circuit arrangements
IPC: H04N5/213
Filed: 1956-08-17
Abstract: 791,494. Pulse- - discriminating circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 7, 1956 [Aug. 10, 1955], No. 24170/56. Class 40 (6). In a circuit for producing a synchronizing pulse only in response to the frame synchronizing signals of a composite television signal which contains the direct current component and has positive-going synchronizing pulses and negative-going image signals the composite signal is applied to an integrating network having a time constant less than three line periods and preferably less than one line period. The output voltage from the integrating circuit being fed to the control grid of a discharge tube from the output of which is derived the synchronizing signal. Fig. 1 shows a discriminating circuit in which the composite television signal, Fig. 2, is applied to a conventional D.C. restorer circuit and to an integrating network comprising resistor 6 and capacitor 7 so that a voltage is produced at the grid of tube 10 having the chain-dotted waveform shown at 23 ... 28 in Fig. 2. Only during the frame synchronizing signal period 17 does the level of the integrated voltage exceed the cut-off level 29, Fig. 2, of tube 10 to produce an output pulse at the anode of the tube which is applied to the frame saw-tooth generator circuit 13. In this way the disturbing effect of interfering pulses such as 20, Fig. 2, is considerably reduced. In the modification shown in Fig. 3, the composite signal is applied to the first grid of hexode tube 36 so that only during positive-going synchronizing pulses will anode current flow in the tube. The signal is also integrated in network 37, 38 and the integrated signal applied to the second control grid of the tube. Thus only during the period t1 to t2, Fig. 2, does anode current flow in the tube if no interruption pulses 18, Fig. 2, occur. The output voltage at the anode load occurring during the frame period is applied, for example, via differentiating circuit 41 to the frame oscillator circuit 42.

Title: Improvements in and relating to synthetic resins and methods of manufacturing the same
IPC: C08G8/38
Filed: 1934-08-23
Abstract: A flexible artificial resin composition is made by compounding a C-stage dialkyd resin with a semi-cured phenylalkyd resin and curing the compounded mass.  The term dialkyd resin includes the products of reaction obtained by reacting a polyhydric alcohol having three or more hydroxyl groups, a polybasic organic acid, a dihydric alcohol and a dibasic aliphatic acid, with or without modifying agents such as drying oils, fatty acids and natural resins.  The term phenalkyd resin includes the products formed by the reaction of a phenol and an aldehyde in the presence of an A-stage alkyd resin as disclosed in Specification 421,866, [Group IV].  In an example, a flexible di-alkyd resin was prepared, e.g. as disclosed in Specification 365,140 by reacting glycerol, phthalic anhydride glycol and adipic acid in such proportion that the mol ratio of glycol adipate to glycerol phthalate was 3 : 1. 29,1 parts by weight of this resin was dissolved in 37,4 parts of phenol and 17,2 parts of paraformaldehyde were added.  The mixture was refluxed for about 3 hours, the temperature rising slowly to 115 DEG  C. and then dropping to 105 DEG C.  13,3 parts of dibutyl phthalate and 30 parts of phthalic anhydride were then added and the heating continued at 100-105 DEG C. in the open until a cure of 25 secs. on a 150 DEG  C. hot plate was reached.  The final product was made by compounding on heated rolls 20 parts of this semi-cured phenylalkyd resin with 73 parts of a fully cured dialkyd resin (ratio 3,5 to 1 glycol adipate to glycerol phthalate) and 2 parts of zinc stearate.  Moulded sheets 1/8 inch thick were cured at 150 DEG  C. for half an hour.  Other examples are given.  Specification 396,354 also is referred to.

Filed: 1953-09-03
Abstract: The invention comprises chromium compounds of the formula [D-Cr-D]M2 where M2 is an alkali metal or ammonium cation and D is a dyestuff which has no water solubilising groups which dissociate acid in neutral water of formula <FORM:0741638/IV(c)/1> where R is an unsubstituted or substituted alkyl group having a total of at most 4 C atoms, X is hydrogen or halogen, Y1 is H or an alkyl, cycloalkyl or phenyl group and Y2 is H or an alkyl group and Y1 and Y2 may be found together in the form of a ring by themselves or with oxygen.  They may be made by treating dyestuffs of the above formula in which the hydrogen group of the benzene ring is replaced by OR1 where R1 is as R with chromium-yielding agents so that there is 1 chromium atom to two dyestuff molecules and under conditions to remove R1.  Preferably R and R1 are hydroxyl substituted alkyl groups which may be etherized.  The unmetallized dyestuffs may be made by coupling the diazotised 2, 5-dialkoxy amine with the appropriate naphthol advantageously in an alkaline medium. Specified amines from which the sulphonamides may be derived are methyl-, ethyl-, propyl-, butyl, cyclohexyl-, dimethyl- and diethyl-amines, aniline, toluidines, xylidines, anisdines, phenetidines, piperidine, morpholine and monomethyl and -ethyl-aniline.  Chroming may be effected with chromic sulphate, formate and acetate and alkali metal and ammonium salts of chromosalicylic acid, advantageously at over 100 DEG C in aqueous solution or suspension under pressure preferably in the presence of a wetting or dispersing agent such as turkey red oil at 120-150 DEG C. Chroming may also be effected in alcohol under pressure or in solvents such as ethylene glycol, ethylene glycol monomethyl- or monoethyl-ether, formamide, acetamide or in a urea melt at 135-155 DEG C.  The dyestuffs dye wool and synthetic polypeptide fibres from a neutral to weakly acid bath in blue shades.  In Examples (1) diazotised 1-amino-, 5-dimethoxy benzene or its 4-chloro-derivative are coupled with 1-hydroxynaphthalene-3-sulphonic acid dimethylamide and the resulting dyestuff chromed; (2) diazotised 1-amino-2, 5-dimethoxy benzene is coupled with 1 - hydroxynaphthalene-3-sulphonic acid piperidide and the resulting dyestuff chromed.  In a Table showing chromed dyestuffs preparable as in the Examples the following values are given for R and R1, methyl, ethyl and hydroxyethel, for X, H and C1, for Y2, H, methyl and ethyl, for Y1, H, methyl, ethyl, phenyl, cyclohexyl and Y1 and Y2 combined as a morpholine residue.
