Title: Improved method and apparatus for the manufacture of articles having multilayer wallsand channels, e.g. waveguides
IPC: C25D1/02
Filed: 1966-01-04
Abstract: 1,142,292. Electro-forming waveguides. M. M. ESIPENKO, A.M. MOLCHADSKY and N. K. MURZIN. Jan. 4,1966, No. 384/66. Heading C7B. In making articles having multi-layer walls and channels, e.g. waveguides, by electro-deposition of metal on to uninsulated metal surfaces of a mandrel, e. g. of stainless steel, enveloping the deposited metal layer with plastics, and then withdrawing the mandrel, the electro-deposition is effected using an alkaline electrolyte of high throwing power. Examples of suitable plating baths are those of the cyanide type for silver and the pyrophosphate and ethylenediamine types for copper, while reference is also made to the suitability of a stannate tin bath and of the use of an alkaline ethanolamine bath. A class of coating plastic specifically referred to is an epoxy resin and reference is made to improving its adhesion to an electro-deposited layer of copper by the use of a phenolformaldehyde cement. As shown a stepped central mandrel 1 is releasably secured to an end mandrel 3 and a pre-fabricated metal element 6 to be incorporporated in the finished product is located by a flange mandrel 4 which results in the production of a waveguide with a lateral hole. The portions of the mandrels and the element 6 not to be electro-plated are covered by casings 10, 11, 12, 13 of ebonite or polythene. The deposited metal layer may be built up with solder at depressions and places of mating or jointing of the mandrel surfaces before applying the plastics material. Reference is also made to making waveguides with rectangular, circular, H- or H- shaped crosssection with curved or twisted as well as rectilinear channels.

Title: Improvements in or relating to methods of generating pulses characteristic of sound and like waves
IPC: H04N5/067
Filed: 1939-01-06
Abstract: 523,575. Transmission systems. KOLSTERBRANDES, Ltd., and BEATTY, W. A. Jan. 6, 1939, No. 519. [Class 40 (iv)] [Also in Group XL] Sound, television, and other electrical signal waves are converted into pulses having a time function determined by the form of the wave, by repeatedly deflecting an electron beam across a suitably shaped target in one direction by a constant wave form and in a direction at right angles by the sound wave. Various types of pulse series representing a sine wave 11, Fig. 1, are shown at 12 to 19, these types being referred to in Specification 511,222. Type 12 consists of pulses of constant frequency symmetrically modulated in width in accordance with the wave amplitude, type 13 being derived therefrom by marking the beginning and end of each pulse by a momentary pulse. Type 14 consists of pulses commencing at constant intervals and of width depending on the wave amplitude, types 15 and 16 being obvious derivatives in double and single momentary pulse form. Types, 17 to 19 correspond to types 14 to 16 but the pulses 17 terminate at constant intervals. The target for producing type 12 is shown in Fig. 4, the beam 22 being deflected in direction 25 by a sawtoothed wave and in direction 26 by the sound wave, and the target for producing type 13 is shown in Fig. 5. Targets for producing the other types are described with reference to Figs. 6 to 11 (not shown). In the case of targets such as Fig. 5 having two arms for producing double pulses, the arms may be insulated from each other so that the pulses of the pair may be given different amplitudes. The pulses may also be derived photo-electrically from a fluorescent screen having a suitably apertured mask. Discharge devices of the electron multiplier type described in Specification 519,653, [Group XL], may be used.

Title: Improvements in or relating to Current Limiters or Electric Interrupters.
Inventor: PETTERSEN KRISTIAN
IPC: H01H71/12
Filed: 1916-01-19
Abstract: 100,048. Pettersen, K. Jan. 30, 1915, [Convention date]. Electro-magnetic interrupters. - A current limiter for simultaneously interrupting both parts of a two-rate supply when a pre-arranged maximum current supplied at two different tariffs (for example, for lighting and for heating) is exceeded comprises an electro-magnetic interrupter 8, 10 energized by a coil 7 the whole of which carries the high-tariff current for lighting and a part of which carries the low-tariff current for heating, so that the allowable low-tariff current is greater than the allowable high-tariff current, and when current for both purposes is used at the same time the effect of the heating current upon the interrupter is less than that of the lighting current. When the maximum demand from either or from a combination of both consumption circuits is excessive, the interrupter 8, 10 completes at 11, 12 the circuit of a second electro-magnetic switch 13 which breaks the supply circuit at 4 and the supply circuit is continuously made and broken until the demand is reduced. The coils carrying the two currents may be independent and of different sizes and connected in series or in parallel with one another. Thermal switches.-The actuating member of the interrupter may consist of thin and thick expansible wires 8, 9 carrying the low tariff and high tariff currants respectively and serving to hold a contact 11 out of engagement with a contact 12. A pre-arranged lighting current carried by the wire 8 alone or a higher heating current carried by the wire 9 alone or a combination of these having an equivalent expanding action will complete a circuit at 11, 12 and cause the supply to be intermittently interrupted as before. The wires may be duplicated and connected in parallel.

Abstract: 1,062,191. Braking record tape spools. SOUTHERN INSTRUMENTS HOLDING Ltd. Jan. 6, 1965 [Jan. 8, 1964], No. 931/64. Heading G5R. [Also in Division F2] The drum 2 of a magnetic tape recorder spool (not shown) is braked by a rubber-tyred pressure wheel or roller 3 mounted between a pair of braking arms 4 and 5 which are pivoted on a shaft 10 and biased by a spring 11 to urge the wheel or roller into engagement with the drum when a solenoid 19 is de-energized to release latch member 12 from a spigot 14 on the arm 4. The wheel or roller carries friction pads (7), Fig. 2 (not shown) on its opposite sides which are frictionally-engaged with the arms by an adjustable compression spring (6) such that when the wheel or roller engages the drum and is driven thereby, the drum is braked. The axes of the drum and shaft 10 subtend an angle of about 120 degrees at the axis of the wheel or roller thereby achieving a self-servo action. The latch member 12 may control additional braking arms and wheel or roller for simultaneous braking of a further drum. In a modified arrangement, Figs 3 (not shown), four rollers or wheels and their associated braking arms and latch members are arranged for simultaneous braking of two drums, associated with take-up and feed spools (not shown), rotating in the same direction, either clockwise or anticlockwise. The said adjustable compression spring may be replaced by hydraulic, pneumatic, mechanical or electromechanical means.

Title: Waveform shaping circuit
IPC: G06F1/04
Filed: 1956-01-11
Abstract: 787,939. Pulse gating circuits. NATIONAL CASH REGISTER CO. Jan. 11, 1956 [Feb. 23, 1955], No. 938/56. Class 40 (6). A logical gating circuit has associated with it a corrector circuit which provides a discharge path for unwanted stray capacity associated with the gating circuit during a predetermined portion of the clock pulse period. The Figure shows a corrector circuit comprising discharge tube 19 associated with gating circuits 1a, 1b, 1c which are of the " inclusive or " type producing a high voltage output signal on lead 10 only when one or both of the signals of inputs 4, 5 are at a high level. The effect of unwanted capacity 26 across the output of each gate is to prolong the decay time of the trailing edge of output pulses produced at least 10 and cause faulty operation of the circuit. This is mitigated by rendering tube 19 conductive during the second half of the block pulse period by applying to its control grid an inverted train of clock pulses derived from clock pulse generator 15 via phase inverting stage 21, stray capacity 26 then discharging through tube 19. The output on lead 10 is thus more nearly a replica of the input voltage pulse applied at input 4.

Filed: 1989-01-06
Abstract: PURPOSE:To improve simultaneously both characteristics of chip treatability and tool wear resistance by combinedly adding Pb and S to a steel by the irreducible minimum of quantities, respectively. CONSTITUTION:A martensitic stainless steel has a composition consisting of, by weight ratio, 0.25-0.4% C, <=1.0% Si, 0.3-1.0% Mn, 0.03-0.1% S, 12-14% Cr, 0.05-0.2% Pb, P and Ni as impurities in the amounts of <=0.04% and <=0.6%, respectively, and the balance essentially Fe. In the above composition, the upper limit of S is set because corrosion resistance is deteriorated by S though the wear loss of carbide tool can be reduced with increasing S content. The upper limit of Pb is also set up because hot workability is deteriorated if Pb is contained in large quantities though Pb has the effect of improving machinability, particularly chip treatability.

Abstract: PURPOSE:To improve considerably the positioning precision of a power plate by engaging a locking member which controls the engagement between a sector gear and a driving gear with the power plate, and locking directly the power plate by the locking member. CONSTITUTION:The power plate 10 is arranged in a free reciprocating state and a roller-shaped cam follower 11 provided on the reverse surface of its front part is energized by a movement start spring to be pressed against the outer circumference of the driving cam 9. When the power plate 10 is locked, a sucking plunger 15 is turned on to suck the locking member 12 through a sucking piece 16 fitted to the locking member 12. Therefore, the engagement member 12a atop of the lock member engages the step part 10a of the power plate 10, which is locked at the inner part of a tape player against the force of the movement start spring. At this time, the notch part 3 of the intermittent gear 2 still faces the driving gear 1 and the driving force from the driving gear 1 is not transmitted to the sector gear 2, so neither the sector gear 2 nor the driving cam 9 united with it rotates and the power plate 10 is also at a still.
