Filed: 1961-07-07
Abstract: 1,048,658. Rejecting faulty cigarettes. K. KÍRBER. Aug. 13, 1962 [July 7, 1961], No. 2902/65. Divided out of 1,048,653. Heading A2C. The components of a non-united or imperfectly united group of two cigarettes and an intervening filter are separated by placing the groups in holders which move on a downwardly facing arcuate path of a conveying surface and which co-operate with supporting members which retain united groups in the holders but permit a non-united or imperfectly united component to fall so that the filters are separated from the cigarettes. The groups G are fed from roll 12 into grooves 31 in a testing drum 13, and air jets issuing from blow holes 32 cause the ends 57 of groups which have been incised at 56 as described in Specification 1048653 to be removed by deflectors 55, the removal of the remaining portions of the groups G being assisted by air blown from holes 33. The testing drum is constructed to effect air blast rejection between inner guide bars 52 of filters 30 of imperfectly united groups or those reaching the drum 13 on their own (due to stoppage for some reason of the cigarette feed), whilst cigarettes fed on their own are rejected outside guide bars 53. In a group G missing only a filter rod 30 air blast deforms the hollow wrapper tube for removal by deflection by guide bars 53, the remaining cigarettes being removed as before. The satisfactory groups G are retained by the guide bars 52, 53, 54 and suction applied to holes 34, 35 in the grooves 31. The outer ring 49 of the drum 13 is rotatably mounted by bearings 50 around stationary end unit having annular suction and blower chambers 47, 40 supplied by ducts 48, 42 and communicating for blowing via slots 38, 39 with ducts 36, 37 leading to holes 32, 33, and with the same ducts and holes via slot 41 at a later stage for blowing out empty grooves 31. Suction communication is via slots 45, 46 and ducts 43, 44 to groove holes 34, 35.

Title: Process for making master moulds used in the manufacture of sound records
IPC: G11B3/70
Filed: 1947-02-03
Abstract: 638,006. Electrodeposition on sound record moulds. RADIO CORPORATION OF AMERICA. Feb. 3, 1947, No. 3199. Convention date, Feb. 23, 1946. Drawings to Specification. [Class 41] [Also in Group XXXVIII] A process of making master moulds used in the manufacture of sound records comprises forming a negative record with a gold surface from an originally-recorded sound track cut into a plastic surface, subjecting the gold surface to a solution of strong oxidizing agent whereby it becomes passivated, subjecting the passivated surface to a water rinse at room temperature to wash off excess oxidizing agent, electroplating a metal layer on to the passivated surface to form a metal positive and stripping the metal positive from the passivated surface. As an example, the sound track is recorded on a wax or lacquer matrix which is thinly plated with gold by chemical deposition and by cathode sputtering. The film of gold is backed by a plating of copper and is then separated from the plastic matrix. The gold surface is then passivated by the oxidizing agent which may be a permanganate or a sodium or potassium dichromate. A nickel surface is then plated on the gold surface and is backed by a copper plating, after which the nickel surface is stripped from the gold surface to form the master mould. The Specification as open to inspection under Sect. 91 comprises also the use of another noble metal, for example, silver or platinum, in place of gold. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to function generators
Inventor: ALEXANDER ALFRED JOHN
IPC: G06G7/26
Filed: 1967-01-20
Abstract: 1,220,813. Function generators. ELLIOTT BROS. (LONDON) Ltd. 18 Jan., 1968 [20 Jan., 1967], No. 3201/67. Heading G4G. A function generator, Fig. 1 (not shown), comprises a gate circuit switchable by a pulsewidth modulator responsive to an input signal x representing one parameter and producing a train of pulses of duration representing x which switch the gate from non-conducting to conducting for a second repetitively varying input signal y (=f(t)) having the same period as the output of the pulse-width modulator and representing a second parameter, the output from the gate being passed to an averaging or integrating circuit so that if x varies slowly relatively to y, the output Z is given by a further function of x related to the function f. For example, if y = k 1  sin wt. and the gate opens at t 1  = 0 and closes at t 2  = # where # is directly proportional to x, then Z = k 2  (1 - cos ##), Fig. 2 (not shown). Again if t 1  = #/2 and #αx, Z α sin ##. If the input y is a quasi-differentiated squarewave with t 1  coincident with a step of the basic squarewave, and y = exp(- t/T), Zα[1 - exp(- #/T)] for #αx, and if y is derived from a squarewave through a filter of function 1/1 + ST, t 1  occurs at a squarewave step, and (t 2  - t 1 ) α x, then Zα(1 + x - e<SP>x</SP>). Fig. 5 shows a circuit in which input cosine waveform y α cos #t is applied to averaging unit 3 incorporating an operational amplifier with RC feedback giving lag with transfer function 1/1 + ST and earthed over shunt transistor switch 1 controlled by pulse width modulator 2 comprising high-gain amplifier 4 with input summation resistors 5, 6. The cosine waveform is squared at 7 and integrated at 8, 9 to a triangular waveform and this is applied to resistor 5 while input signal x is applied to resistor 6 for comparison, switch 1 being pulsed for a time interval determined by the magnitude of x, so that the output Z is proportional to sin ##, if #αx. For cosine generation, switch 1 is driven through an "exclusive or" gate receiving both the pulse-width modulated output from unit 2 and the squarewave applied to integrator 8, 9 and operating to reverse the pulse-width modulated signal at alternate half cycles. It is shown that: Zα - 2 cos ## where 2#αx. If input y is sinusoidal and if the input to resistor 5 is a quasi-differentiated squarewave, Z is then proportional to sin log e x. More complex functions may be derived utilizing inputs x varying independently of time. In a modification Fig. 6 (not shown), the waveform for the pulse width modulator is derived from a waveform generator which is synchronized from another waveform generator supplying the input y. Alternatively both waveform generators could be synchronized from a common external source.

Abstract: 1443835 Producing synthetic single crystals VSES ORDENA TRUDO KRAS ZNAM N I INST SINTEZA MINERAL SYRYA 24 Jan 1974 03323/74 Heading BIG Synthetic single crystals are produced from hydrothermal solutions in an autoclave having a growth chamber in its top portion and a dissolution chamber in its bottom portion by placing in the dissolution chamber seeding plates in holders, oriented so that their basic growing surfaces are inclined at an angle of 90-45‹ with respect to the vertical, starting material and a suitable solvent and heating the autoclave so as to create a temperature gradient between the dissolution chamber and the growth chamber thereby ensuring the growing of a crystal on the seeding plates. It is advantageous to screen the upper growing surface of the seeding plates by a plate of inert material so ensuring that crystal growth of high quality proceeds predominantly on the lower growing surface and eliminating the formation of a upper defective half of the crystal. As shown in Fig. 1 the seeding plates 3 are placed in the top portion, of an autoclave 1 and the charge 6 in the lower portion, the upper and lower growing planes of the seeding plates being represented by 4 and 5 respectively. The growing of high quality quartz crystals is exemplified using crystalline quartz and an aqueous solution of Na 2 CO 3  or NaOH as starting materials in the autoclave.

Abstract: 129,586. Barbarou, M. J. B. May 8, 1918, [Convention date]. Spray carburettors. -In spray carburettors of the kind in which the jet is fed from an auxiliary fuel well, the upper part of the well communicates with the choke tube and also through a restricted opening with the atmosphere, and the fuel nozzle is supplied from the well through orifices at different levels in the well. This is stated to compensate the mixture for varying altitudes above sea level. The well is divided into upper and lower parts by a partition, and is fed from the float chamber through holes d, f, the latter being restricted. The two parts of the well communicate through an air-tube h, and a number of tubes y which terminate at different heights above the partition, and are perforated at various levels below. A pipe k connects the upper part of the well to the choke-tube, and the restricted opening to the atmosphere at n is adjustable. When the engine is running, the different depressions created in the well cause the petrol level to vary from u to z, so that a varying number of the feed-tubes j are covered and the feed to the nozzle is altered. In a modification, applied to a carburettor having a suction-actuated supplementary-air valve, the tubes j may feed separate side-by-side nozzles, and another nozzle, side by side with these, is formed as one leg of a U-tube, the other leg being open to the atmosphere, fuel being supplied direct from the float chamber through a restricted orifice to the middle of the U.
