Title: Improvements in or relating to electroplating
Inventor: KAPP DEREK IVOR COLIN
IPC: C25D17/00
Filed: 1960-01-01
Abstract: 867,560. Electroplating. MULLARD Ltd. Jan. 1, 1960, No. 66/60. Class 41. A method of electrodepositing a metal on separated conductive portions 5 on an insulating base 4 comprises making electrical connection to the portions 5 by way of separate electricallyconductive bodies 7, e.g. steel balls, which touch one another and are caused to move relative to the portions 5. The member 4, 5 is located in an insulating container 1 rotated about an inclined shaft 2, metal studs 8 delivering current from a contact 9 to the balls 7. Alternatively, electrical connection to the balls 7 may be by a contact placed in the container and insulated from the electrolyte solution, and the bodies 7 may be agitated by rocking the container 1 instead of rotating it. The bodies 7 may be housed in a jig in the container 1, the jig being caused to move relative to the container. Two examples are described. In one, employing a grid anode, 200 gms. per litre K 4 [Fe(CN) 6 1 and 30 gms. per litre of a mixture of gold potassium cyanide and free potassium cyanide was the electrolyte, a voltage of 6 producing an amperage of 4, the container being rotated at 17 r.p.m. In the other, 200 gms. per litre of CuSO 4  and 56 gms. per litre H 2 SO 4  was the electrolyte employing a copper anode at 6 volts to produce 1.5 amps. The steel balls 7 were plated with copper prior to being used in the container.

Title: Inter-multipoint communication control system
Inventor: SETOGUCHI TOMOYUKI
IPC: H04L12/18
Filed: 1989-01-05
Abstract: PURPOSE:To eliminate the need for always monitoring a transmission right holding terminal by returning a response indicating the transfer of transmission right when a data terminal holding the current transmission right has already ended transmission, and at the time of requiring a little more transmission, neglecting the request of the transmission right. CONSTITUTION:At the time of receiving a transmission right request command 10, a receiving circuit 100 transfers the command 10 to a command response analyzing circuit 300. The circuit 300 informs the reception of the transmission right request to a transmission right holding flag collating circuit 500. When the self-terminal of the circuit 500 does not hold the transmission right or when the self-terminal requires more transmission right though it has already held the transmission right, the circuit 500 neglects the received command 10 by referring a transmission right holding flag circuit 600.
Patent DK-19588-A (DK)
Inventor: HANLET JACQUES M
IPC: H05B41/14
Filed: 1988-01-18
Abstract: Self-regulating electronic ballast system 10 which is protected against being unloaded and which contains an energy source 12 for activating at least one vapour discharge tube 66 with a regulated current and a limited voltage in order to keep the input and output power of the vapour discharge tube 66 at a predetermined value. The ballast system 10 contains a filter circuit 11 connected to the energy source 12 by an induction circuit 15 connected to the filter circuit 11. The induction circuit 15 has a primary winding 42 with output, which forms an auto-transformer configuration for determining the size of the regulated current. The induction circuit 15 contains a trigger control winding 48 to generate a control current and a non-loading protective circuit 99 to generate a voltage across the vapour discharge tube 66 dependent upon the regulated current and to keep the output voltage at a predetermined value when the vapour discharge tube 66 is disconnected from the electronic ballast system 10. In this way the output voltage of the ballast system 10 is principally reduced when the vapour discharge tube 66 is disconnected from the whole circuit. This ensures greater reliability and a longer lifetime for the vapour discharge tube 66. <IMAGE>

Patent GB-283578-A (GB)
Title: Improvements relating to high frequency signalling systems
IPC: H04B1/46
Filed: 1928-01-03
Abstract: 283,578. British Thomson-Houston Co., Ltd., (Assignees of Bird, L. F.). Jan. 14, 1927, [Convention date]. Combined transmitting and receiving arrangements; thermionic amplifiers and generators; wired wireless.-Relates to means for automatically regulating the sensitivity of a receiver in a high-frequency duplex system. The input circuit of the receiver is shunted by a valve, the grid bias of which is automatically controlled in response to the operation of the transmitter. In a combined transmitter and receiver, the bias on the relief valve is controlled by the directcurrent component from the oscillation generator. As shown in the Figure, the control or relief valve 25 is shunted across the input circuit 24. The bias on the grid 27 is derived in part from a battery 29, and in part from a resistance 17 in the plate-cathode filament of the detector valve 12. Normally the valve 25 is non-conductive, but is made to by-pass excess energy when the current through the resistance 17 exceeds a certain valve. In transmission when speech current is applied across the leads 4, oscillations are generated by the valve 40 and are modulated by the valve 35 which is inserted in series with the former valve across the high-tension battery 53 and earth. Direct current will flow through both valves in series to the cathode 45, and thence through a conductor 47 and choke 48 through part of the bias-controlling resistance 17 to earth at 31. This automatically disperses the valve 25 to shunt away any of the side-band frequencies that may be transferred across the balanced transformer 5, and protects the receiver from the transmitting circuit without impairing the normal reception of incoming signals. Specifications 243,683 and 246,808 are referred to.

Title: Disazo dye derived from j-acid urea
IPC: C09B33/056
Filed: 1974-12-09
Abstract: 1477161 A disazo dye derived from J-acid urea IMPERIAL CHEMICAL INDUSTRIES Ltd 9 Dec 1974 [7 Jan 1974] 00624/74 Heading C4P The novel disazo dyestuff of the formula is obtained in admixture with minor amounts of the two symmetrical disazo dyestuffs by coupling 1 mol of diazotized 2-naphthylamine-6- sulphonic acid and 1 mol of diazotized 4-amino- 3-methylbenzene sulphonic acid with one mole of J-acid urea. The 2 diazotized amines may be coupled simultaneously with the J-acid urea or consecutively in either order. The coupling solution may be used as such without isolating the dye since the dye has high aqueous solubility, and this solubility may be made even greater by adding known solubility improvers such as urea or substituted ureas. Particularly useful aqueous solutions may be obtained by coupling in the presence of triethanolamine so that the product is at least partly in the form of a triethanolamine salt. In one example an alkali metal hydroxide or ammonia is used in place of the triethanolamine, and the dye is isolated by the addition of 5-30% of an alkali metal chloride or ammonium chloride and the paste redissolved in aqueous urea or substituted urea. The novel dyestuff gives yellowishscarlet shades on cellulosic materials, e.g. cotton, but is particularly useful for dyeing paper.
