Title: Improvements in or relating to antenna systems
IPC: H01Q11/06
Filed: 1931-03-13
Abstract: 373,692. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Carter, P. S. ; Port Jefferson, Long Island, New York, U.S.A.) March 13, 1931, No. 7813. Convention date, June 11, 1930. [Class 40 (v).] A directional antenna system comprises a pair of angularly disposed linear conductors, a plurality of half wavelengths long, and energized to produce standing waves thereon, the direction of radiation being the bisector of the angle formed by the conductors. In the arrangements shown in Figs. 2, a, b, c, a transmission line 10 supplies out of phase energy to a pair of wires A, B forming an angle 2alpha with each other and either joined together at their apex and fed intermediate their ends or forming continuations of the transmission lines or preferably joined through a U-shaped loop 12 whose length can be adjusted by the bridge 14, the feeder being tapped adjustably to the loop at 18. The loop is non-radiating and can be made of suitable length so that the system presents a pure resistive load to the transmission line, which is equal to the surge impedance of the line for maximum efficiency. The angle alpha is determined from the value of # which makes the expression for the field strength H, in the direction desired, a maximum. H is given for a conductor an odd number of half wavelengths long by the expression and for one an even number of half wavelengths long by An empirical formula which may be used is:-alpha=50À9 (1/#)<-0À513> degrees, where # is the wavelength. In order further to concentrate the beam pairs of wire A, B and A<1>, B<1>, Fig. 4, may be placed in parallel horizontal planes at least one half wavelength apart, the lower pair being at least one half wavelength above the ground. To obtain a unidirectional characteristic the system is duplicated, Fig. 5, a further set of wires a, b, being placed behind the set A, B an odd number of quarter wavelengths and having standing waves generated thereon ninety degrees leading or lagging those in A, B, according to whether forward or backward radiation is desired. Several of these systems may be placed broadside on, Fig. 8, or end on, Fig. 9, being excited in the latter case with suitable lagging or leading phase-difference between each unit U. Alternatively, the units may be arranged to form a diamond shaped figure, Fig. 10, or in overlapping formation, Fig. 10a. Specifications 340,892 and 346,023 are referred to.

Title: Hydroformylation of olefines
IPC: C07C29/16
Filed: 1957-03-11
Abstract: Straight-chain oxygenated products are obtained by a process comprising reacting a straight-chain a -olefin, free or substantially free from olefins of other types, with carbon monoxide and hydrogen in the presence of 0.1 to 1 per cent by weight (based on the olefin feed) of a Group VIII metal compound capable of forming a metal carbonyl under the conditions of the reaction, at a temperature in the range of 60-100 DEG  C. and a total pressure in the range 2000-10,000 p.s.i.g., for a time sufficient to convert a major portion of the olefin to oxygenated products and recovering an aldehyde product having one more carbon atom than said olefin, said aldehyde product containing a major portion of straight-chain compounds.  Suitable olefins for use as starting materials are, for example, n-butene-1, n-pentene-1, n-hexene-1, n-heptene-1 up to n-eicosene-1.  A mixture of such olefines may be used if a mixture of alcohols is required.  A diluent such as a hydrocarbon, alcohol or aldehyde may be present. The preferred catalysts are cobalt compounds, particularly oil-soluble cobalt compounds such as cobalt oleate and salts of other long-chain organic acids.  Alternatively pre-formed cobalt carbonyls are used as catalysts.  The aldehyde product may be hydrogenated under conventional conditions to give the corresponding alcohols.  Suitable conditions are, for example, a temperature of from 140 DEG  to 320 DEG  C., a pressure of from 2000 to 5000 p.s.i.g., and a catalyst such as supported or unsupported nickel, copper chromite, or oxides and sulphides of tungsten or molybdenum.  In the examples: (a) heptene-1 is treated with carbon monoxide and hydrogen in the presence of cobalt carbonyl; the product is then hydrogenated in the presence of a nickel on kieselguhr catalyst to give octyl alcohol; and (b) butene-1 is treated with hydrogen and carbon monoxide in the presence of cobalt carbonyl; the product is hydrogenated over a supported nickel catalyst to give a straight-chain alcohol.

Title: Fluid control valves for double-acting fluid pressure motors
IPC: F03B11/04
Filed: 1960-03-07
Abstract: 895,157. Valves. NEW YORK AIR BRAKE CO. March 7, 1960 [April 22, 1959], No. 7933/60. Class 135. A four-position control valve for a doubleacting fluid-pressure motor 66, Fig. 2, e.g. operating a bulldozer earth-moving blade, has a housing 11, Fig. 1, with inlet and exhaust ports 12, 13, two motor parts 14, 15, Fig. 2, and a bore 16, Fig. 1, encircled by nine annular chambers 17-19 and 21-26; chambers 21, 23 open to the inlet port 12 via a passage 29 in which is a relief valve 33 whilst chambers 17, 22, 26 communicate with the exhaust port 13 via a manifold 31. A passage 32, Fig. 2, interconnects chambers 19, 24. A hollow valve plunger 34, Fig. 1, slidable in the bore 16 has three grooves 35-37 and four lands 38, 39, 41, 42, the interior of the plunger 34 being divided into two chambers 47, 48 by a plug 49 ; four sets of radial passages 52-55 extend from the chamber 47 to the surface of the plunger and two similar sets 56, 57 extend from chamber 48. A check valve 58 is disposed in chamber 47 and a replenishing valve 59 in chamber 48. The outer ends of the chambers 47, 48 are closed by plugs 44, 45, the former being part of a fourposition detent mechanism. In the neutral position of the plunger, fluid from a pump enters the port 12 and passes freely to a reservoir through passage 29, chambers 21, 23, grooves 35, 36, chamber 22, manifold 31, and port 13 ; the ports 14, 15 are closed by lands 38, 41, so that the pump is unloaded and the motor 66 hydraulically locked. To raise the blade, the plunger 34 is moved to the right to interrupt communication between ports 12, 13, and connect the port 12 to the port 14 through passage 29, chamber 21, radial passages 53, chamber 47, check valve 58, radial passages 52 and chamber 18, the port 15 being opened to the manifold 31 via radial passages 56, chamber 48, radial passages 57 and chamber 26. The blade is lowered in a similar manner upon moving the plunger 34 to the left and since the front face of the replenishing valve 59 is acted upon by the fluid exhausting from the motor and the rear face of the valve is open to the inlet passage, the valve opens and enables this exhausting fluid to pass to the other side of the motor and assist the pump since, due to the blade weight, the rate of change of volume on the expanding side of the motor is greater than the pump delivery rate. When the blade contacts the ground the pressure rise will cause the replenishing valve 59 to close. Further leftward movement of the plunger into the " float " position causes the ports 12, 13, and 14, 15, to be interconnected whereby the motor 66 reciprocates freely under the action of external forces. The check valve 58 prevents release of the positive pressure which exists in the chamber 18 when the blade is in an elevated position and when the plunger 34 is shifted to the " raise " position.

Title: Improvements in and relating to photographic cameras
IPC: G03B3/02
Filed: 1957-03-11
Abstract: 809,392. Photographic cameras. VOIGTLANDER A.G. March 11, 1957 [March 15, 1956], No. 7941/57. Class 98(1) A photographic camera with exchangeable objectives or similarly attachable devices and a shutter release member in the camera body has a locking device in the camera body which locks the shutter release and/or the film wind except when the objective is mounted in position. As shown in Fig. 1, the objective 2, which fits into a bayonet ring 4 on the camera body 1, has a pin 7 which bears against a lever 8 pivoted within the camera body at 9, rocking it against action of a spring 10, to hold its end 11 clear of a notch 12 in the shutter release plunger 13. When the objective is removed, the end 11 of lever 8 enters the notch 12 to prevent movement of the shutter release. In a modification, Fig. 2, the lever 8 has a nose 15 engaging a recess 14, e.g. a peripheral groove, in the objective mount. When the objective is removed, an arm 11 engaging a notch in the shutter release plunger 13, and a tooth 17 on an arm 16 engages a toothed wheel 18 on the filmwinding shaft. A stop pin 19 limits the movement of the lever 8. When a spacing ring is used between the objective and the camera body, it carries a slidable spring-urged pin bearing on the objective mount at one end and on the lever 8 at the other end, so that the locking lever acts when either the objective or the objective and spacing ring is or are removed.

Title: A method of and means for piecing up sliver in textile machines
IPC: D01H5/00
Filed: 1951-04-06
Abstract: 689,429. Preparing fibres for spinning. DOMINION TEXTILE CO., Ltd. April 6, 1951 [Aug. 31, 1950], No. 8086/51. Class 120(i) For piecing up sliver in a lap winder, drawing frame or the like, a free leading end of sliver from a reserve supply is placed in a first position for access thereto by the tail end of a sliver feeding from a depleted supply, the reserve sliver end is retained loosely in the said first position beneath and in alignment with the normal travel of the feeding sliver end, and the feeding sliver tail end on depletion or breakage is caused to gravitate into overlapping wiping contact with the reserve sliver leading end so as to adhere thereto and draw the latter into the machine. As shown, an adjustable support bar 30 carrying a supplementary guide plate 32, and a reserve sliver end supporting bracket 40 having upwardly directed sliver retaining pins 42, are secured to the known slotted guide plate 20 of a lap winder. In operation the ends of slivers A from full reserve cans 14 are passed through slots 22 in plate 20 and hooked on to the retaining points 42, while the slivers B fed into the machine from supply cans 12 pass through guiding openings 36 in plate 32 and slots 22. When any of slivers B breaks or is depleted, the free sliver end B drops down slot 22 against the sliver end A; the wiping action of sliver B over sliver A is sufficient to cause the two ends to unite so that sliver A is drawn forward into the machine. The operator can at his leisure replace the empty can, move can 14 to the outside position and place the new feeding sliver end in the slot 36, place a new reserve can in the inside position, and hook the end of the new reserve sliver on to point 42. The amount of overlap between the sliver ends is controlled by the distance guide 32 which is positioned from guide plate 20.

Abstract: 252,834. Siemens Bros. & Co., Ltd., Petithory, E. A., and Garrod, E. R. March 27, 1925. Electric-motor actuation; centrifugal actuation; retarding and time - limit devices; actuating.-In timelimit relay devices of the kind in which a circuit closing or opening device is operated by an electric motor through reduction gearing a predetermined time after the said relay device has been put into operation, the circuit closing or opening device is coupled to the gearing by a clutch which is controlled by a centrifugal governor driven by the electric motor. The single split phase induction or other motor 2 drives through a coupling 5a, shaft 7, and reduction gear 3 the device for operating the switch. Feathered on shaft 7 is one plate 8 of a toothed clutch which is movable by means of straps 9, operated by a centrifugal governor 6 on the motor shaft, into engagement with plate 10 to which is attached a timing disc 11 freely mounted on shaft 7 but positioned thereon by screw 11<a>. The disc 11 has an annular slot 12 having an enlarged opening 12<a> through which are inserted appropriately shaped bolts having specially shaped nuts 13, 14 which are adjustably positioned in the slot 12 to act as strikers to open and close, respectively, the switch. Striker 13 engages a tongue 15 which is part of a sector 23 carrying a pin 24 which engages a number of knife blades 16 to move them from fixed contacts 17, aided by springs 25. A clock spring 18 attached at one end to the disc 11 on separation of the clutch plates. In operation, the device is assumed to be applied to shutting down a generator should its load fall and the motor is connected to the supply through one pair of contacts 16, its circuit being closed by a relay controlled by the generator load. When the latter falls, the motor is started and, on reaching full speed, the governor 6 moves to engage the clutch and drive the disc 11 through the shaft 7. After an interval, the striker 13 moves the sector 23 to the right and by means of the pin 24 raises the blades 16 to cut out the generator, the motor 2 being also disconnected and the clutch freed. The spring 18, which has meanwhile been wound up, now drives the disc 11 back until the striker 14 engages the tongue 15 and by means of a pin 26 recloses the switches 16, 17. In Fig. 3 the pin 14 is shown for clearness sake away from its real position which should be abutting on the tongue 15. The clutch plates are formed with an unequal number of teeth for facilitating engagement.
