Title: Apparatus for distinguishing between various fm broadcast multiplex transmissions
IPC: H04H20/89
Filed: 1973-05-08
Abstract: 1416627 Multiplex radio signalling RCA CORPORATION 8 May 1973 [9 May 1972] 21747/73 Heading H4L A system for transmitting conventional FM two-channel stereophonic signals or fourchannel surround stereophonic signals, is provided with means for indicating which type of signal is being transmitted. Transmitter.-The L-R signal is amplitude modulated on a 38 kHz subearrier which is suppressed and is combined with the L + R signal and a 19 kHz pilot signal for stereophonic transmission in conventional manner. For quadraphonic transmission an additional 38 kHz subcarrier in quadrature with the L-R subcarrier is generated and is modulated with, for example, the difference F-B between the front and rear signals, this subcarrier also being suppressed. The resultant is added to the conventional stereophonic signals and the composite signal so derived frequency-modulates the main carrier. SCA signals may also be combined in normal manner. To provide an indication when the signals are two-channel stereophonic the modulator for the quadrature subcarrier is unbalanced in this mode as by applying a direct potential to the modulator so that a 38 kHz component will be transmitted. At the receiver, the presence of the 19 kHz pilot and unmodulated 38 kHz subcarrier indicates two channel stereophonic reception, the presence of the 19 kHz pilot above indicates quadraphonic reception and the absence of the 38 kHz and the 19 kHz signals indicates monophonic reception. Receiver.-The composite signal derived from the FM tuner 103, Fig. 2, is supplied to a pilot signal separator 109, a stereophonic subchannel detector 113 and a quadrature subchannel detector 115. A 38 kHz subcarrier is derived at 105 from the pilot signal and phase-shift network 111 provides the quadrature subcarrier, the subcarriers being supplied to the demodulators 113, 115 respectively. The demodulated signals together with the sum signal from the tuner 103 are matrixed and de-emphasized at 117, 119, 121, 123 and supplied to the loud-speakers 127, 129, 131, 133 respectively. During two-channel reception the unmodulated 38 kHz quadrature subcarrier is detected at 139 and operates an indicator 141 and also blocks gates 143, 145. The detected subcarrier may also be used to block gates 147, 149 to disconnect the loudspeakers 129, 131. In a modification, Fig. 3 (not shown), the demodulation is carried out on a time-division basis.

Title: Vacuum testing apparatus
IPC: G01M3/40
Filed: 1974-08-09
Abstract: 1479137 Photo-electric vacuum detectors EVANS MEDICAL Ltd 9 Aug 1974 [9 May 1973] 22021/73 Heading G1A Apparatus for detecting vacuum in containers comprises: means to convey the containers between contacting electrodes; means for producing alternating voltage across the electrodes; means for detecting a discharge in a container when between the electrodes; and means responsive to the absence of a discharge to operate an alarm or a rejector device. Vials V partly filled with substances in vacuo pass on a conveyer 2 between carrier plates 4, 5 supporting opposed resilient electrodes 13, 14 for contacting each vial in turn in regions above its filling level. The electrodes 13, 14 receive 8kV at 15kHz from an oscillator (not shown) which, if a satisfactory vacuum exists, will excite a blue discharge in the unfilled space. A lens 17 in a tube 16 set in an opening of the plate 5 collimates light received from a vial under test on to a photomultiplier 15. A first combination of a lamp 8 and phototransistor 6 provides pulses to a first counter (10), Fig. 1 (not shown) displaying the total number of vials tested. A second combination of a lamp 9 and phototransistor 7, connected to logic circuits gated by the photo-multiplier 15, provides pulses to a second counter (12), Fig. 1 displaying only the number of vials which fail to flow and are therefore regarded as faulty. Absence of glow is further used to light a lamp 18 (Fig. 1) and may also sound an alarm and operate means to direct a faulty vial into a reject bin.

Title: Improvements in and connected with rotary pump machines
IPC: F04B1/113
Filed: 1929-07-18
Abstract: 338,546. Eyston, G. E. T. July 18, 1929. Revolving-cylinder pumps; pump actuating mechanism. - A cylinder revolving in a fixed casing contains a reciprocating lenticular piston which has trolling contact on its internal surface with a fixed eccentric shaft the ration of diameter of internal surface of piston to shaft being 2 :1. In another form a circular piston has extensions which reciprocate in the pumping spaces. A piston a, Fig. 1, has flattened tips which slide on surfaces e of the revolving casing b. The internal surface g of the piston rolls around a fixed shaft f, and a crescentshaped brush n prevents sliding of the piston at its contacting point with the shaft b<1>. Balancing of the rotating parts may be secured by adding masses. During rotation of the cylinder b, ports k connect the pumping space d either with an inlet l or a delivery m. The bush n may be replaced by a roller, or the surfaces of shaft f and piston g may be formed as tooth gears. Figs. 5 and 6 show a modified arrangement in which circular-shaped pistons a, a<1>, slide between guides x and have extensions t, the tips of which rub on the surfaces e. Discs 2 are fixed eccentrically about the shaft f<1> and the axes 4, 6, 5 of the discs, shaft, and centre of rotation of cylinder b respectively lie in one plane. Pistons a, a<1>, a<2> reciprocate along the guides x, rolling contact being maintained between the tracks g and the shaft f<1>. The centre piston a<1> is twice as long and twice as heavy as each end piston, and is disposed at 90‹ to the end pistons for balancing purpose. Partitions S separate the three working chambers. The cylinder b is rotated by means of a gearwheel h. Plates 1 shield the pumping spaces d<1> from the bearings y. The shaft f<1> may be angularly adjusted during operation to vary the point at which ports k open either to inlet or outlet ports and m, as shown in Fig. 6, a lever 14 being turned through a small angle by a screw 16. A key 17 connects the turning gear to the shaft f<2>. An oil pump 10 is driven by a gear-wheel 11 and supplies lubricant through a pipe 8 to passages 7 and holes 9. In a modified construction the shaft f<1> is rotated in the opposite direction to that of the casing by gearing. Specifications 320,398 and 327,119, [both in Class 110 (ii), Rotary engines &c.], are referred to.

Title: Method and apparatus for filming articles by vacuum deposition
IPC: C23C14/56
Filed: 1959-06-29
Abstract: 869,397. Coating by vapour deposition. LIBBEY-OWENS-FORD GLASS CO. June 29, 1959 [July 2, 1958], No. 22167/59. Class 82(2) Sheets are coated by vapour deposition in an evacuated chamber by sealing a sheet in an intake chamber, simultaneously evacuating said intake chamber and cleaning a side of the sheet to be coated transferring the sheet through an opened communication to the coating chamber, closing the communication, coating the sheet while evacuating a discharge chamber, transferring the coated sheet through an opened communication to the evacuated discharge chamber, closing the communication, bringing the discharge chamber up to atmospheric pressure, and removing the coated sheet therefrom. The sheets may be glass, metal, or plastic. As shown, sheets 48 of glass in carriers 49 move successively into positions F, E, D, C, B, and A in intake chamber 21, cleaning chamber 22, coating chamber 23, and discharge chamber 24. When intake chamber 21 is empty, valve 26 is opened to the atmosphere, and the chamber supplied with dry air from dryer 25 to prevent the ingress of moisture. Fresh sheets 48 are charged, valve 26 closed, and vacuum pump 28 begins to reduce the pressure in the chamber. During the first portion of the evacuation dust free air is directed from guns 29 on the surface of the glass and dust collected at 30. Plutonium probes 31 prevent the formation of a static charge on the glass which may be heated meanwhile by heaters 32. When chamber 21 reaches a pressure of 10<SP>-3</SP> mm. Hg, valve 27 is opened and the sheets are advanced to position E in cleaning chamber 22 where they are further heated by heaters 33. At position D the sheets are glow discharge cleaned in a confined inner chamber 34 by a glow plate 35, the vacuum in the chamber being reduced while cleaning from 10<SP>-4</SP> mm. Hg to 1-10 microns Hg by introducing oxygen through pipe 37. In positions C and B the sheets are moved to at least 40 inches from evaporant sources 39 and 40 which are screened from each other by baffle 41. The vacuum chamber 23 is maintained at 10<SP>-5</SP> mm. Hg by pump 43. The coated sheets pass through valve 45 to discharge chamber 24 from which they can pass via valve 46 and out of the apparatus. A modification discloses the intake, cleaning, and discharge chambers made equal in width to the vacuum chamber (Fig. 7 not shown) so that it is unnecessary to provide equipment for moving the carriers away from and towards the centre line in the vacuum chamber. In another modification (Fig. 8 not shown) parallel pairs of intake, cleaning, and discharge chambers are used to overcome the same problem while, in a further embodiment (Fig. 9 not shown) a modified vacuum chamber is used in which evaporant sources 39 and 40 are adjacent the outer walls of the chamber so that the carriers are able to travel through each chamber without diversion from a straight line path.

A valve for dispensing carbonated and other liquid under pressure has a storage chamber with at least one plunger for controlling flow to a surge chamber through a restricted passage, the outlet of the surge chamber is out of line with the inlet and of greater area so that liquid is reduced to atmospheric pressure before discharge. The body 10 of the valve has a tubular support 12 and an inlet 25 for the carbonated water and inlets 42, 43 for syrups. A bore in the body has a plug 14 with three bores for a valve plunger which has a head 28 and a stem 27 and seating in a thimble 29 bearing against the bottom of the plug 14 and urged upwardly by a spring 31. The plug has a diametral bore 30, sealing rings 26 and a groove 16 corresponding with the passage 17 communicating with a tapered bore 18. A plug 23 fits loosely in the bore and extends to a surge chamber 19 closed by a plate 20 having orifices 45. The block has also two bores 32 each with a valve plunger 33 urged upwardly by a spring 37 having an end valve 38, and head 39 and sealing ring 40. A cup 44 surrounds the bottom and is in communication with the surge chamber. The bore has a passage 41 communicating with the inlet syrup pipes. Levers 49, 50 and 51 operate the valves. The levers 49 and 51 rest on both water and syrup valves to operate both together while the lever 50 operates water alone. The water valve is operated before the syrup valve initially and finally closing it last to clean the outlet. On operating either lever 49, 51 the syrup passes to the inlet 41, to chamber 35, past valve 38, 40 to the outlet orifice. The carbonated water passes to the storage chamber 24 through passages 30, 16, 17 and 18 to the surge chamber 19, cup 44, past valve members 38, 40 to the outlet orifice. To provide a high velocity waste jet a tube connects with the central handle. The tube passes through the block 14 and seats on a valve in the storage chamber. The tube has a connection with an outlet tube at the orifice fitted with an injector. Operating the handle rearwardly provides a high velocity water-jet by unseating the valve in the storage chamber to give direct communication with the outlet.

Title: Shock reducing and cushioning wheel mounting for vehicles
IPC: B60G5/02
Filed: 1939-07-31
Abstract: 534,530. Vehicle spring suspensions. LARISON, G. L. July 31, 1939, No. 22206. [Class 108 (ii) ] A multiple wheelmounting comprises a longitudinal beam, a pair of wheel-assemblies each comprising a wheel spindle extending perpendicular to the beam in opposite directions therefrom and normally co-axial with each other, the spindles being connected by transverse hinges to the beam, and inter-connected by a resilient linkage pivoted to the beam, so that each wheel can move up and down independently of the other, out shocks are cushioned whether the wheels move up and down separately or simultaneously. The beam may be fixed to the vehicle frame, or may be connected thereto by a transverse pivot; in the latter case it mounts a pair of wheels at each end. In the construction shown in Figs 1, 3, 5 and 6 each of a pair of wheels A, B is mounted at one end of a rocking beam I pivoted at K to a transverse member L connected to the pole M. Each wheel rotates on a stub axle 11, 11<SP>1</SP> fixed to longitudinal arms 14, 141 independently pivoted on co-axial transverse pivots 17 to the end of the beam I. The stub axles are connected by universally-jointed links 30, 301 to cranked levers 19, 19<SP>1</SP> pivoted on a pin 20 on the beam I, these levers having arms 22, 221, between which a compression spring 23 is mounted on a loose bolt 24. Thus each wheel can rise and fall independently in its own vertical plane. Upward movement of the arms 14, 141 is limited by stops 18, so that if one wheel tyre is punctured the other wheel of the pair takes the load. In a modification the cranked levers 19, 19<SP>1</SP> and spring 23 are replaced by a transverse laminated spring pivoted at its centre on the pin 20 and having its ends connected to the universallyjointed links 30, 301. In the modification shown in Fig. 10 each stub axle is connected to a piston 46 or 46<SP>1</SP> working in hydraulic cylinder 47 or 471 pivoted on trunnions 48 on the beam I. The liquid spaces above the pistons are connected by pipes 51, 51<SP>1</SP> to a common spring-loaded reservoir (not shown).
