Title: Thin film circuit assemblies
IPC: H05K1/16
Filed: 1976-03-05
Abstract: 1531327 Printed circuits ROBERT BOSCH GmbH 5 March 1976 [7 March 1975] 08825/76 Addition to 1412986 Heading H1R In a thin film circuit assembly (Fig. 1) of the kind described in Specification 1,412,986 a layer of valve metal 2 patterned according to the basic geometry of a circuit network is applied to an insulant substrate 1, the metal being of tantalum, niobium, aluminium, zirconium, or hafnium. An oxide layer 3 produced by partial anodization of layer 2 is formed in the regions defining a resistance material. In other regions defining conductor and contact areas, five metallic layers are deposited, layers 4, 6 being copper separated by a diffusion barrier layer 5 of, e.g., iron, nickel, cobalt. A layer 10 of nickel is formed on copper layer 6, thereupon a gold layer 11 and finally a layer 7 of tin-lead solder. The composite layers 2, 4, 5, 6, 10, 11, 7, define both the conductor paths and solderable terminal contacts for external connections and further componentry. After production of the layered assembly as set forth in the Specification referred to by successive etching and anodizing to define coated, conductor and resistance areas, the assembly is cleaned in trichlorethylene, and formed by electrolessly depositing a nickel layer 10 from nickel chloride and sodium hypophosphate on copper layer 6, electrolessly depositing a gold layer 11 on the nickel from a solution containing gold ions, and lead-tin solider coating the gold layer from molten solder in a reducing gas atmosphere; the solder not wetting the oxide layer 3 of the resistance tracks 2. The solder may alternatively be deposited by wave soldering, and the nickel layer also prevents interdiffusion. A nitride layer of valve metal may replace the valve metal 2 as a resistance region.

Title: Improvements in the production of yeast
IPC: C12N1/18
Filed: 1923-03-29
Abstract: 195,963. Pollak, A. April 4, 1922, [Convention date]. Yeast.-To wort in which yeast has been cultivated until reproduction has nearly ceased is added a further supply of yeast which has been subjected to treatment which increases the permeability of the cell-membrane, in order to increase its power to assimilate nitrogen and to utilize the worts more thoroughly. The treatment is effected bv the aid of enzymes which decompose semicellulose. Such enzymes are afforded by germinated cereals and leguminous seeds, the stomachs of ruminants, pancreatic secretions, " mortified yeasts," or the production or autolysis of yeast, or of fungi of the genera Aspergillus and Mucor. The yeast which has been treated with these enzymes may, before being added to the wort. bo cultivated in a medium containing such fermentation and autolytic products, or distillers' wash or spent liquid from the manufacture of yeast. The Specification as open to inspection under Sect. 91 (3) (a) states that similar results can be obtained by increasing the acidity or alkalinity of the mash. This subject-matter does not appear in the Specification as accepted.
Patent GB-1417606-A (GB)
Title: Fluid controlling apparatus
IPC: F15B13/04
Filed: 1973-02-23
Abstract: 1417606 Valves DAIKIN KOGYO CO Ltd 23 Feb 1973 [24 Feb 1972 29 Feb 1972] 9016/73 Heading F2V A valve for controlling a fluid motor 61 has a directional control spool valve 55 and a fluidpressure operated plunger 30 to control the supply of pressure fluid to and from the spool valve and to by-pass surplus fluid to a divided flow line 74 in which may be inserted a second fluid actuator 75. On moving the spool 55 from its neutral position, in which the ports a and b are blocked, fluid flows through a metering gap 54 to operate the motor and this flow produces a pressure drop across the gap. The pressures occurring on each side of the gap are fed to chambers 9 and 36 at the ends of the cavity in which the plunger 30 operates: the plunger has a control spring 35. The plunger has a band 31 which controls a first pressure controlling gap # and a flow dividing gap α and a second pressure controlling gap γ. Pressure fluid is delivered from a pump 70 and returns to a tank 80. For a given opening of the control gap 54 the flow through it is maintained constant, and hence the motor speed despite varying pressure as a result of varying load on the motor, by the operation of the plunger 30 which varies the gaps # and γ, any fluid surplus to the requirements of the motor 61 being by-passed through the gap α into the divided flow line 74 to operate a second actuator 75, if provided. The main relief valve 73 only opens under excessive load on the motor. If the load on the motor becomes negative so that it operates as a pump sucking in fluid, the low pressure created on the input side of the motor, which is fed to the chamber 36, causes the plunger to move to the right, closing the gap # so that supply to the motor from the pump 70 is cut off. Fluid from the pump now passes entirely through the gap α into the divided flow line 74 and it combines with the fluid, now at a higher pressure, returning from the motor, acting as a pump, through passage 25. This combined flow operates the check valve 26 and returnes to the inlet of the motor which thus continues to rotate. If pressure at the outlet from the pump exceeds a value set by the pressure relief valve 72 the valve will open to return the fluid to the tank.  Other embodiments are described in which the fluid is metered on its return from the fluid motor, instead of in the supply side as described above. This allows the pressure relief valve 72  to be dispensed with, pressure control being provided by the plunger 30 even when the motor is acting as a pump.

Title: Improvements relating to ion-exchange treatment of water
Inventor: COMPTON HAROLD ERNEST THOMAS
IPC: B01J49/00
Filed: 1953-04-01
Abstract: 777,102. Softening water. UNITED FILTERS & ENGINEERING, Ltd. June 10, 1954 [April 1, 1953], No. 9027/53. Class 46. [Also in Group XXXVI] The conductivity of effluent from a cation exchanger is measured at two points effectively time-spaced along the effluent path, and during a working run these conductivities are equal ; when they differ by an optimum amount the exchanger is manually or automatically regenerated, and when, near the end of a rinse following the regeneration, they are equal again, the rinsing is terminated and normal working resumed. Effluent from a hydrogen exchanger X is divided at Y, part flowing direct to a conductivity cell E1 and the remainder flowing through a time-lag device T in the form of a baffle tank (as shown), a coil of piping or the like to a second conductivity cell E2 so as to ensure a predetermined time-lag between the effluents in the two cells. When regeneration has become necessary the electrical conductivity of the effluent passing through conductivity cell E1  will be lower than that of the effluent passing through cell E2 (which represents the effluent at an earlier period). This results in a differential conductivity which is at once indicated by a conductivity meter M, and this differential conductivity can be arranged to give a signal, or automatically initiate regeneration, when it reaches an optimum value. During regeneration the conductivity meter M is automatically put out of service and valves A and B closed. After a predetermined period, when the rinse operation is nearly complete, valve B is opened and the meter M comes into service so as to show the differential conductivity between the rinse water passing continuously through the cell El and the lower conductivity effluent still retained in the time-lag device T and cell E2. When the rinse-water conductivity falls to approximately that of the water in the time-lag device T and cell E2 the hydrogen exchanger is manually or automatically put back into service and valve A is opened. If the apparatus is to be operated intermittently and therefore shut down before exhaustion of the exchanger, it would be necessary to close a valve (not shown) in the downpipe feeding cell E2 when valves A and B are closed, and to open it again when valves A and B are opened. The cation exchanger may be used in conjunction with an anion exchanger.

Abstract: 406,872. Optically recording and reproducing sound. RADIO CORPORATION OF AMERICA, 570, Lexington Avenue, New York, U.S.A. March 25, 1933, No. 9100. Convention date, May 9, 1932. [Class 40 (ii)]. F I G. 5. In photographic sound-recording' the undulations of the sound record trace which lie upon one side of the medium line thereof, and the undulations which lie on the opposite side of the said line, are recorded separately on tracks spaced apart from each other, the objects of the invention being to minimize background noise in reproduction, to improve high frequency response, and to enable a reproducing system to be used in which the exciter lamp may be fed with A.C. without the production of hum. A record such as is shown in Fig. 5 is made by an oscillograph apparatus, Fig. 3, which vibrates the shadow of a screen 25 to and fro along a slit in a fixed member 23, the shadow covering the slit completely when there is no vibration. This is shown in Fig. 4, in which 20 is the central patch of shadow in a vibratory light beam 18 which is reflected by the oscillograph mirror on to a slit 19. Another form of sound record, in which the separate component elements of the record are spaced from the edges of the sound track, is shown in Fig. 8. Such a record is made by the apparatus shown in Fig. 6, in which a " light stop " 34 having triangular openings 35, 36 is arranged between the lamp 38 and the mirror 41, corresponding images being produced, as shown, on opposite sides of the slit in a member 37. In reproducing sound from the record, by means of the apparatus shown in Fig. 9, the separate images of the positive and negative components of the record are focused respectively on two cathodes 52, 53 in a single photoelectric cell 46. The cell is connected as shown to the primary of a transformer 54.

Filed: 1953-04-02
Abstract: 725,357. Magnetrons. GENERAL ELECTRIC CO. April 2, 1953 [April 3, 1952], No. 9151/53. Class 39 (1). Adjacent segments of the anode have adjacent edges shaped to form interaction gaps which are curved or shaped angularly so that their middle portions lead' their end portions with respect to the direction of motion of the electron stream. By virtue of the axial component of radio frequency field thus introduced, useful electrons rotating in phase with the alternating electric field become concentrated'at'the centre of the interaction gaps, whilst out of phase electrons, which are liable to cause back bombardment of the cathode, are ejected at the ends of the anode segments and are collected by end plates. Anode block 3, Fig. 1, is mounted on a metal header 2 and enclosed in a glass envelope 1. An aperture 4 in the anode defines the resonant circuit and this communicates with interaction gaps which are chevron shaped. A hot cathode 7, cylindrical in shape, has end plates 12 to collect electrons expelled from the interaction space. Power is extracted from the resonator by means of an induction coupling loop 16 one end of which is carried to the outside of the envelope through a hole in the anode block forming a co-axial line output 14. In a modification, of the multiple hole and slot type, the anode block is preferably made in two halves 19 and 19', Fig. 3, which are brazed together inside a metal container 26. Chevron-shaped gaps 24 communicate with cylindrical resonators 22. The interaction gaps may be curved instead of chevron shaped (Fig. 6, not shown).
