IPC: A01F15/10
Filed: 1981-08-26
Abstract: An agricultural baler is provided including a bale case (3), a feed platform (16) communicating therewith and a feed mechanism (6) for feeding crop material across said feed platform (16) into said bale case (3). The feed mechanism (6) comprises first feeder elements (31-33), second feeder elements (73-74), the second feeder elements being rotatable about a first axis (68) and about a second axis (26) offset relative to the first axis, generally stationary means (82) coaxial with said second axis and means (78-83) drivingly coupling the feeder elements (73-74) to the generally stationary means (82). The arrangement is such that, as the feeder elements (73-74) are rotated around the second axis (26) and around the generally stationary means (82) coaxial therewith in one direction (37), the means (78-83) drivingly coupling the feeder elements (73-74) to the generally stationary means (82) cause the feeder elements (73-74) to rotate in the opposite direction (95) around the first axis (68). The first feeder elements (31-33) may be replaced by an auger. <IMAGE>

Title: Direct discharge ventilators
IPC: F24F7/02
Filed: 1981-10-16
Abstract: A powered, direct discharge ventilator comprises a base (B) having an extraction fan duct defined by a cylindrical wall portion (11) enclosing a fan impeller (L) of a fan (K) mounted on the base. A windshield (D) shelters a non-return shutter (S) which closes the extraction fan duct when the fan is not operating. The shutter (S) is hinged on a pair of arms to float up on the discharging airstream when the fan is operated. When the fan is stopped, the shutter (S) closes gravitationally. To assist in holding the shutter (S) closed under high wind conditions, a wind deflector (W), carried by a bird-guard (G), directs the wind in a downwardly directed stream or to the top of the shutter (S). The wind defector may be mounted so as to project only partly above the windshield and may extend around only part of the fan duct opening depending on the prevailing wind. The shutter S may be replaced by an assembly of four hinged flaps. <IMAGE>

Title: Vehicle body repair detector
Inventor: TAYLOR MICHAEL JOHN
IPC: G01N27/72
Filed: 1981-10-17
Abstract: A vehicle body repair detector comprises a Hall effect sensor (18) and a magnet (25) mounted behind the sensor so that when the sensor (18) is applied to a vehicle body the magnetic flux of magnet (25) passes through said sensor into the ferrous material of the vehicle body. In order to give a useful visual display, the sensor is arranged to provide three output levels corresponding respectively to the sensor being applied to a region of a vehicle body where (i) the ferrous material of the body is separated from the sensor only by the thickness of the normal paint layers (i.e. an undamaged region), (ii) the ferrous material of the body is separated from the sensor by a relatively thin layer of non-ferrous filler and paint layers (i.e. a shallow dent has been repaired), and (iii) ferrous material is completely absent (i.e. a hole has been repaired) or is widely separated from the body surface (i.e. a deep dent has been repaired). The three signal levels are used to control a pair of red and green lamps e.g. LED's (24), (26) such that in condition (i) the green lamp is fully ON and the red lamp is OFF, in condition (ii) both the red and green lamps are ON and in condition (iii) the red lamp is fully ON and the green lamp is OFF. <IMAGE>
Patent GB-2091964-A (GB)
Title: Circuit for detecting dropouts
IPC: H03K5/19
Filed: 1981-12-16
Abstract: A circuit for detecting dropouts in a received input signal, e.g. a frequency fc reproduced from a video disc, comprises means 3,41-44 for up-converting the frequency of the received input signal and a decision circuit 1 including retriggerable monostable multivibrators MM1, MM2 and an OR gate circuit 13. The supply of a frequency- converted input signal to the decision circuit 1 increases the probability of detecting dropouts, by allowing a reduction in the time- out period  tau 1 of monostable MM1, the lower limit for which is determined by the minimum frequency supplied thereto. As shown, limiter amplifier 3 supplies a squared, frequency- doubled signal to circuit 1. Alternatively, Fig. 7 (not shown) a mixer (81) provides the sum of fc with an oscillator frequency fr. Decision circuit 1 indicates the absence of a signal (monostable MM1 not triggered) or the presence of a signal of a frequency below a threshold 1 / tau 1 (monostable MM1 allowed to time out). <IMAGE>

Title: Process for producing synthesis gas
IPC: C09C1/48
Filed: 1982-05-10
Abstract: One or more hydrocarbons containing nickel and vanadium in a concentration of 100 to 2000 ppm, are partially oxidized with the formation of soot as a by-product, in a sufficient amount that the total concentration of nickel and vanadium in the soot does not exceed 5% by weight based on the soot, the synthesis gas is cooled to 160 to 350 DEG C and the soot and ash are separated dry by means of one or more filters from the cooled synthesis gas. Preferably no recirculation of the soot to the gasification of the one or more hydrocarbons is effected. The soot may be converted in a reactor, other than one used for the oxidation of the one or more hydrocarbons, into synthesis gas. <IMAGE>

Title: Soldering metal components
IPC: B23K3/047
Filed: 1982-06-11
Abstract: A method of soldering together mating surfaces of two metallic components, e.g. 11, 12, which is especially applicable to the bonding of surfaces of relatively large area, consists in placing the assembled components, with a suitable solder, e.g. 13, between their mating surfaces, between dies 1, 2 of appropriate shape which have been preheated at least to the fusion temperature of the solder, maintaining the dies at or above said temperature and under pressure until the mating surfaces of the components have reached soldering temperature to effect fusion of the solder, then cooling the assembly to a temperature below the solidus temperature of the solder, suitable by applying water cooling to the dies and removing the soldered together components. If necessary the components are precoated with a solderable metal. The dies may be heated by means of electrically heated plates 7, 8 in contact therewith. Some specific examples of methods employed for bonding metal plates together are given. The method is rapid and forms strong bonds over substantially the whole of the mating surface, with few or no voids and no undesirable reaction products. <IMAGE>
