Title: A new or improved machine for spraying fruit and other trees or plants and crops generally
IPC: A01M7/00
Filed: 1920-08-09
Abstract: 171,744. Edmonds, J. Aug. 9, 1920. Manure and seed distributors.-A machine for spraying or powdering trees &c., is provided with a motor for driving both the spraying or powdering apparatus and the travelling wheels and is adapted to pass over bushes between the trees without damaging them. According to the Provisional Specification 23314/20, the machine may be fitted with apparatus for drilling. The chassis 1 is supported on two driven rear wheels 2 and two front steering wheels 3 mounted on stub or stud axles in downwardly projecting brackets 4, 5. The axles 6 of the steering wheels project from vertical spindles 7 passing through bearings in the frame 1. Above the frame, the spindles are fitted with arms 9 connected together by a rod 10, and one of the spindles with a second arm linked to a steering-wheel 13. The ignition and throttle controls for the engine 14 are mounted on a dashboard 18. The engine shaft is connected by a clutch 19 to a power shaft ending in a gear box containing change-speed, reversing, and differential gearing for driving two transverse shafts 22 connected by chain gearing with the wheels 2. Two air-pumps 32, 38 are driven from the power shaft through chain gearing and an auxiliary shaft 28. The pump 32 delivers air at a high pressure to the lower part of a cylindrical tank 34 containing the spraying liquid. The tank 34 is provided with a pressure gauge 35, a relief valve 36, and a branched delivery pipe 41 fitted with cocks and unions for flexible hose. The pump 38 delivers a large volume of air at a low pressure to the base of a pyramidal powder container 40 which is provided with a branch delivery pipe 43 having cocks and unions. Either the spraying-apparatus or the powdering-apparatus may be omitted. The machine may travel without operating the pumps, and the pumps may be operated while the machine is stationary. The machine may be used as a tractor.

Title: Improvements in the production of ferro-alloys with low content of carbon
IPC: C21C7/00
Filed: 1939-08-18
Abstract: 542,573. Alloys; extracting metals; crucibles. HORGARD, G. Aug. 18, 1839, Nos. 23887 and 23888. Convention dates, Aug. 22, 1938, and July 8, 1939. [Class 82 (i)] Iron alloys such as ferro-chromium, ferromanganese, ferro-molybderium, ferro-tungsten, ferro-titanium, ferro-vanadium, ferro-niobium, and stainless steel are made in an electric induction furnace having high frequency heating means and low frequency agitating means by treating a finely divided charge of oxide, non- carbonaceous reducing agent and if required a flux such as magnesium oxide, stirring the charge during reduction, tapping part of the molten metal while leaving in the furnace at least one third of its entire volume, and drawing off slag as required. The mixture may be pre-heated and charged into a molten metal bath in the furnace, and the process may be worked continuously. The mixture may also contain exothermic constituents such as sodium nitrate with an excess of ferro-silicon, or small quantities of substances which will promote cementing or sintering, such as waterglass. The furnace crucible may be conical, widening upwards, with a conical angle of 60 degrees or more. The Specification as open to inspection under Sect. 91 refers also to the production of metals such as chromium and manganese. This subjectmatter does not appear in the Specification as accepted.
Patent GB-1113191-A (GB)
Title: Control apparatus utilizing pure fluid logic control and rotative stepping motor
IPC: F15C1/00
Filed: 1965-06-04
Abstract: 1,113,191. Controlling turbine or fluid motors. BENDIX CORPORATION. 4 June, 1965 [15 June, 1964], No. 23974/65. Heading G4P. [Also in Division G3] The speed of rotation of a turbine or fluid motor 20 (Fig. 1), driven by pressurized fluid from a valve 30 actuated by a stepping motor 32, is compared in a logic control device 36 with the required speed of rotation set up on a speed selection lever 54, the output from the device 36 controlling the stepping motor 32 and hence via the valve 30 the turbine or fluid motor 20. In the form shown (Fig. 2, not shown), bi-stable gates (68a, 68b) and monostable gates (70a, 70b) receive pulses from the speed sensor unit 44 and the speed selection unit 58 to give an output along a first channel (106a) if the required speed is less than the operating speed of the motor and along a second channel (106b) if it is greater than the speed of the motor. These output pulses control further bi-stable and monostable switches in the logic control unit 36, the outputs from which are applied to gate amplifiers (70f, 70g, 70h, 70k, 70n) in the power control unit 34. The gates control bellows (126-140, 162-176, Figs. 4 and 5, not shown) so that the first pressure pulse pressurizes for example a pair of bellows (136 and 176) only to load a gear member (200) in a common sense causing it to tilt and rotate the central shaft of the motor (32). Each further pressure signal will cause rotation of the shaft until the speed of the motor 20 (Fig. 1) reaches the required speed.

Title: Improvements in means for determining the draft and trim of a ship
IPC: B63B39/12
Filed: 1938-08-20
Abstract: 518,285. Ships draft gauges. GILLIE, J. W. Aug. 20, 1938, No. 24552. [Class 113 (i)] In draft gauges for ships of the type in which a suitably protected transparent tube with a scale is lowered over the side of the ship with a valve in open position for the entry of water, the connection to the valve takes the form of a flexible joint to overcome any inequalities in the wire connected to the trigger which is operated from above. As shown a universal joint E Fig. 3 is interposed between the wire C and the spring pressed valve A. In order to cater for different lengths of line for ships in ballast or loaded a readily released catch is employed, two similarly shaped pieces of metal H. J, Fig. 6, are employed,' one being attached to the tube and the other to the line. Specification 233,525, [Class 113 (i)], is referred to.

Abstract: 711,910. Garage lifts. GALLAY, R. H. Oct. 22, 1951, No. 24601/51. Class 78 (3) In a vehicle hoist the wheel supporting platforms 2, 2<SP>1</SP> are attached to winch drums 13, 14 which are wound up and down cables 17, 17<SP>1</SP>, 20, 21 when rollers 4, 4', 5, 5<SP>1</SP>, are rotated by the driving wheels of a vehicle on the platforms. The rollers 4<SP>1</SP>, 5<SP>1</SP> are mounted at the ends of aligned half-shafts 8, 8', which are normally connected by a clutch 9, but which are disconnected when the dutch is disengaged on the vehicle reaching a predetermined height by a vertically adjustable member 27. Further operation of the vehicle engine is then transmitted through the differential gear to the rollers 5, 5', which are free to rotate without raising the platforms. On reversal of the wheel drive, the friction in the differential gear and the weight of the vehicle enables the platforms to be lowered slightly to re-engage the clutch. The drums 13, 14 are mounted on a shaft 15 which is journalled at 10, 10<SP>1</SP>, on the platform 2', and which also carries a worm wheel 12 in mesh with a worm 11 on shaft 8. Each pair of rollers may be interconnected by chains 6. The platforms 2, 2<SP>1</SP>, are rigidly mounted on members 3 and are slidable on uprights 1<SP>1</SP>.

Abstract: 921,004. Push - button switches. M. FRACHON. July 7, 1961 [July 13, 1960], No. 24601/61. Addition to 848,000. Class 38 (5). The switch of the parent Specification has included in it a retarding mechanism, which after the microswitch is liberated from the action of the actuating cam, retards its return to the position against the adjustable stop. As shown, the shaft 17 of the retarding mechanism 16 is freely rotatable in the clockwise direction but is only slowly rotatable in the anticlockwise direction. The microswitch assembly 12, 24 is connected to the shaft 17 of the retarding mechanism by links 18, 19. Interposed between the microswitch and the fixed cam 14 is a rotatably mounted support 22 which carries a cam follower 8. When rod 2 is depressed, support 22 and microswitch assembly 12, 24 move together against return spring 11. When the rod is released the push-button 13 retracts, operating the microswitch. The button remains retracted whilst the retarding mechanism and spring 11 return the switch assembly to their original position. In Figs. 10, 11. 12 (not shown) the push-rod carries a rack which meshes with a pinion driving a cam actuating the microswitch, and the movement of the microswitch is conveyed to the retarding device by a sector and pinion.
