Title: Improvements in and relating to electrical signal systems
IPC: H04H20/88
Filed: 1959-10-20
Abstract: 875,909. Diplex radio signalling. PHILCO CORPORATION. Oct. 20, 1959 [Oct. 20, 1958], No. 35486/59. Class 40(5) Two carriers 40, 42, Fig. 1A, having the same frequency but different phases are each amplitude modulated by one of two stereophonic signals, the modulated carriers being combined to give a resultant or average carrier 52 having four sidebands 44-50, and the invention resides in a receiver for a carrier modulated in this, or a like, manner comprising a mixer 12, Fig. 2, and local oscillator 14, a phase comparator 34 developing a signal indicative of the phase difference between the output of mixer 12 and the output of a reference oscillator 22, means controlled by this signal to maintain the phase difference at a predetermined value, and two synchronous detectors 18, 20 supplied with demodulating signals of different phase by reference oscillator 22. Networks 24, 26 provide phase shifts of magnitude and direction, for example of +45 degrees, - 45 degrees, such that the phases of the demodulating signals correspond respectively to the phases of the original carriers 40, 42. The desired phase difference between the outputs of mixer 12 and oscillator 22 may be maintained by means of a low pass filter 36 and frequency control stage 38, e.g. a reactance valve, controlling either oscillator 22 or oscillator 14. When tuning to a different station, the output of mixer 12 is momentarily interrupted and the phase and frequency of the controlled oscillator may drift, an undesired beat frequency thereby appearing at reproducers 30, 32 and phase comparator 34 when tuning is effected. To avoid this, the beat frequency is fed through a band pass filter 60 to a peak detector 62 whose output is applied to block either reproducers 30, 32 or detectors 18, 20 until the correct phase and frequency of the controlled oscillator is again established by means of control loop 36, 38.

Title: Improvements in and relating to the manufacture of semiconductive devices
IPC: H01L21/288
Filed: 1957-11-14
Abstract: 873,484. Semi-conductor devices; electroplating. PHILCO CORPORATION. Nov. 14, 1957 [Nov. 14, 1956], No. 35496/57. Classes 37 and 41. A method of treating a semi-conductive device comprising a semi - conductor body and an attached electrode includes the steps of plating a conductive material over the body and electrode and then removing the conductive material from the surface of the electrode and a surrounding region of the body. In the embodiment a surface barrier transistor 13 (Fig. 1), comprising indium emitter and collector electrodes 18, 17 plated in opposed depression in a germanium or silicon wafer 14 and a nickel base tab 20 is electroplated with gold from a solution containing specified amounts of potassium auricyanide, cyanide, and carbonate in water and rinsed in water. The gold adheres firmly to the semi-conductor but forms a poorly adherent porous layer on the indium electrodes which may be removed by etching in hydrochloric acid. The acid penetrates the porous layer and attacks the underlying indium thus dislodging the gold layer. Etching is preferably continued until the indium electrodes are isolated from the remaining gold plate by annular regions of uncoated semi-conductor. Other noble metals, such as platinum may be used instead of gold in the above method which is also applicable to the manufacture of junction transistors and diodes.

Filed: 1971-07-29
Abstract: 1362965 Change-speed gears; positive clutches EATON CORP 29 July 1971 [3 Aug 1970] 35592/71 Headings F2C and F2D In a change speed gear including two parallel shafts carrying intermeshing gear-wheels, at least one of the wheels is axially movable on its shaft to effect engagement of a resiliently loaded jaw clutch for establishing a driving connection between the wheel and shaft, and the arrangment is such that when the wheel is moved axially the two elements of the clutch are brought into contact with each other and one of them is displaced against its resilient loading and subsequently returned by its loading to effect engagement of the clutch on achievement of substantial synchronization of the two elements of the clutch. As shown, a main shaft 23, common to both a main transmission section 12 and an auxiliary transmission section 13, extends between input and output shafts 16, 77 and carries gear-wheels 31, 32, 33, a reverse wheel 34, and gear-wheels 71, 72. The wheel 72 has a driving connection with the output shaft, and a wheel 18 is driven by the input shaft. All of these wheels are rotatable relatively to the shaft 23 and axially movable thereon by selector forks (not shown). The wheels 18, 31, 32, 33 are in continuous mesh with, and float between, diametrically opposed pairs of wheels 25, 26, 27, 28 fast on layshafts 21, 22, the wheel 34 is in continuous mesh with wheels (not shown) meshing with wheels 29 on the layshafts, and the wheels 71, 72 are in continuous mesh with diametrically opposed pairs of wheels (not shown) fast on two further layshafts (not shown). The clutches comprise collars, e.g. 42, 53, Fig. 3, splined to the shaft 23 and urged apart against stops 46, 58 by a spring 47. The collars have external teeth 48, 54 which can be engaged with teeth 49, 56 of gear-wheels 33, 32, and the edges of the teeth have conical surfaces 51, 52. To engage a gear in the main section a shift lever (not shown) is actuated and by an appropriate selector fork (not shown) moves a wheel axially on the shaft 23 so that a clutch collar is engaged and moved axially against spring pressure by engagement of the conical surfaces 51, 52 until the speeds of the shaft and wheel become synchronized and the spring is able to effect engagement of the clutch. To effect a change of ratio in the auxiliary section 13 the desired ratio is preselected and the shift lever is operated to select neutral in the main section 11 whereupon a fluid-operated piston (not shown) moves the wheels 71, 72 axially to disconnect one from, and connect the other to, the shaft 23 through a clutch 41B.

Title: Improvements in and relating to the refining of metals
IPC: C21C7/076
Filed: 1930-11-28
Abstract: In a method of refining metals, a layer of refining materials which will melt at a temperature below the melting temperature of the metal to be refined is introduced into the bottom of the furnace and the metal to be refined is fed into the furnace on the top of the refining layer.  The charge is then heated from above the refining material and the latter melts and forms a liquid layer at the bottom of the furnace, the metal as it melts descending through the refining layer and being thereby purified. Part of the metal may be charged into the furnace in advance of or simultaneously with the refining materials and the rest of the metal charged on the top of the refining materials.  The refining materials contain sodium, potassium or barium hydroxides, singly or in combination, calcium carbide or calcite and carbon in any of its solid forms except graphite.  The metals treated may be iron, steel, zinc, copper, aluminium or lead. When treating copper or aluminium, the refining materials comprise sodium carbonate or potassium hydroxide and silica.

Title: Improvements in or relating to machines for packing cigarettes, cigars and similar rod-shaped articles
IPC: B65B19/10
Filed: 1933-12-21
Abstract: 410,708. Packeting cigars, cigarettes, &c. AKTIEBOLAGET G. AHRENS MEKANISKA VERKSTAD, 20, Alstr÷mergatan, Stockholm. Dec. 21, 1933. No. 35979. Convention date, Dec. 23, 1932. [Class 94 (i).] In a machine in which cigarettes, cigars, or like rod-shaped articles are fed from a magazine into distributing compartments between substantially vertical blades from which two or more rows at a time are ejected by pushers into packets, the number of compartments is double that necessary for a single packeting operation and the blades are adapted to swing about their upper ends to bring half the compartments alternately in front of the pushers. Means are provided where necessary for adjusting the positions of the pushers in accordance with the different inclinations of the blades. The blades 1 having their lower ends turned inwardly are pivoted near their upper ends on a carrier 4 which is rapidly reciprocated by pressure against a cam disc 20 on the shaft 17, while the outermost blades 1<x> are connected to pivoted plates 7, constituting the bottom of the magazine. Near their lower ends the blades are connected by pins with bars 11, 12, which are linked together by the pin of the middle blade and are moved to and fro by a rocking arm 14 bearing against a cam 16 to bring half the compartments alternately in front of the pushers 21, the latter being reciprocated by a pivoted arm 28 carrying at its other end a roller engaging a groove in a disc 29 on the shaft 17. As the compartments are brought in front of the pushers the lower ends of the corresponding blades converge downwardly to bring the cigarettes close together. As shown, three rows of cigarettes are ejected at a time, and the three rows of pushers are mounted on carriers 22, 23, 24 on a slide 25 moved by the arm 28. The lowest carrier 22 is fixed on the slide 25, while the carriers 23, 24 are capable of slight lateral, movement to compensate for the different relative positions of the rows of cigarettes to be ejected. This is effected by pairs of pivoted jaws 32, 33 and 34, 35 which are rocked by links 47, 52 controlled by cams on the shaft 17. When twenty cigarettes are packeted in rows of 7, 6 and 7, a piece of metal 62 is fixed to each outermost blade 1<x> to prevent the ejection. of the seventh cigarette of the middle row, In a modified machine for packeting cigars a single row of pushers serves for ejecting two rows of cigars, no adjustment of the pushers being necessary on account of the greater width of the compartments.
