Title: Fuel tank of automotive internal combustion engine
Inventor: SHIOBARA MASAJI
IPC: B60K15/035
Filed: 1970-02-09
Abstract: 1,255,598. Fuel tanks. NISSAN MOTOR CO. Ltd. 9 Feb., 1970, No. 6160/70. Heading B7H.

Title: Gas liquefaction process
IPC: B63B1/38
Filed: 1966-02-11
Abstract: 1,106,736. Liquefaction of gases. LUMMUS CO. 11 Feb., 1966 [16 Feb., 1965], No. 6265/66. Heading F4P. Compressed gas, e.g. methane, air or nitrogen is liquefied by passage through heat exchangers 14, 16, 18, 20, 22, 24 cooled by external refrigerants arranged in cascade formation and is then sub-cooled by passage through an exchanger 26 in a closed nitrogen circuit comprising a multi-stage compressor 74, after coolers 80, 82, 84, exchangers 72, 68 traversed by reverse flowing nitrogen from the warm end of sub-cooler (26), exchangers 70, 66 cooled by an external refrigerant and an expander 64 which exhausts through a line 60 to the cold end of the sub-cooler. Cold liquefied gas at high pressure is flashed to just above atmospheric pressure into a drum 28, product liquid is withdrawn to storage whilst flash vapour is passed through a line 100, exchangers 68, 72, a compressor 106 and refrigerators 40, 46, to assist cooling of propylene and ethylene therein.

Title: Improvements in or relating to pneumatic and like tools
IPC: B25D9/16
Filed: 1930-02-25
Abstract: 349,912. Percussive tools. ARTHUR, J. and HOLMAN BROS., Ltd., Camborne, Cornwall. Feb. 25, 1930, No..6279. [Class 124.] In percussive tools, drills, &c. provided with a fluid-actuated valve reversed by compression and with an exhaust silencer, the reversal of the valve is facilitated by pressure fluid continually admitted to the forward side of the valve, and the exhaust port is enlarged by altering the position of the rearward or of both rearward and forward edges to counter the effect of the silencer. The main cylinder and tool-holding arrangements 2 may be of any preferred form; the substantially central open exhaust port 3 may be a single enlarged port or in the form of two ports side by side. The valve comprises a disc portion 7 and a guide 8 provided with an axial passage 9 which allows pressure fluid to pass to a valve recess 10. Fluid is supplied by a passage 13 to two annular passages 14, 15 connected through longitudinal boxes to the cylinder ends when the valve moves. The outer edges of the valve are chamfered to permit the access of pressure fluid thereto. The forward seat 16 is of greater diameter than the back seat 17. Since the area of the recess 10 is greater than the end area 8 of the valve, the fluid pressure on the excess area assists the rear movement of the valve. The forward movement of the valve is assisted by the pressure on the area 8.

Filed: 1975-05-12
Abstract: 1513718 Spraying apparatus T B SNELL 12 May 1975 [12 Feb 1974] 06309/74 Heading AID [Also in Division B2] In a spraying apparatus, spraying medium is pumped from nozzles in a flexible pipe which is paid out to a controlled extent from a storage device, and which is suspended clear of the ground. As shown, the flexible pipe 4 with nozzles 5 passes over a pulley 9, and is suspended between tractors 1, 2. The storage device is the drum 8 of a reversible winch 7 which controls the length of pipe extended. The flexible pipe may be suspended from a flexible element paid out from a second storage device, and which spans the same length of ground as the pipe. Protection of the flexible pipe against excess tension during use may be provided by a quick-release device or a torque-sensitive clutch.

Patent GB-575274-A (GB)
Title: Improvements in and relating to means for reciprocating printing press beds
IPC: B41F3/58
Filed: 1944-04-05
Abstract: 575,274. Printing-machines. LINOTYPE & MACHINERY. Ltd., and SPENCE, F. April 5, 1944, No. 6332. [Class 100 (ii)] A bed-reciprocating mechaanism for printing-machines is constructed with a constantlydriven shaft 9 fitted with a sliding gear-wheel 4 which engages alternately an upper rack 5 and a lower rack 6 on a rack frame 7 connected to the bed 1. Reversal of the bed reciprocation between motions at constant speed in opposite directions by means of the driving-gear 4 is obtained by means of sliding cross-heads 18, 19 actuated by a crank on the shaft 9 and connecting- rods 16, 17, the cross-heads being connected by rods 21, 23 to sliding blocks 22, 24, at the opposite ends of the machine, fitted with abutments 30, shaped as shown in Fig. 3. As the gear 4 comes out of mesh with the upper rack after moving the bed to the right in Fig. 7, a reversing pin 29 on the bed engages a recess at the front of the block 22 which constrains the motion of the pin 29 and of the bed. The block 30 is also engaged by a pivoted latch 34 mounted on the bed, which is oscillated by a roller 37 moving in a fixed cam track 39. The pin 29 and latch 34 slow down and reverse the bed as the shaft 9 moves through a little more than half a revolution. Then the latch is raised as the roller 37 rides on the left part of cam 39 and finally the gear 4 engages rack 6 to move the bed at constant speed to the left while the roller 37 rides on a rod 40 which guides the roller 37 into a cam 38 which controls the catch while the bed is again reversed by the block 24 and abutment 30 and latch 34. The abutments are formed with inclined parts 41, Fig. 3, to facilitate action of the latches.

Title: Process for stripping and recovering aroma
IPC: A23F5/50
Filed: 1965-02-15
Abstract: A process for the recovery of aroma constituents from aromatic liquids, e.g. fruit juices, comprises breaking up a stream of aromatic aqueous liquid maintained at a temperature sufficient to effect volatilisation of its aromatic constituents with an inert gas, e.g. nitrogen, whereby the aroma is desorbed by the gas, separating the aroma bearing gas from the liquid and contacting this aroma bearing gas with an aroma absorbing aqueous liquid medium maintained at a temperature to cause condensation and absorption of the aroma constituents desorbed by the gas, desorption and absorption being carried out while maintaining the aroma constituents isolated from oxygen by the inert desorbing gas.  A suitable apparatus is described.

Title: Improvements in or relating to control systems for variable pitch propellers
Inventor: CROWE ROBERT KELMAN
IPC: B64C11/38
Filed: 1957-02-26
Abstract: 828,858. Variable pitch propellers. BRISTOL AERO-ENGINES Ltd. Feb. 17, 1958 [Feb. 26, 1957], No. 6458/57. Class 114 A control system for a variable pitch propeller includes pitch lock means operable by the onset of a predetermined negative-torque in the propeller drive transmission to lock the propeller against pitch fining movement. In the embodiment of Fig. 1, a double acting hydraulic pitch change motor 12 having a fixed brake stop 26 and a fixed feathering stop 27 has a fine pitch line 13 and a coarse pitch line 15. To coarsen the pitch oil is supplied under pressure via line 14, by-pass 16 and non-return valve 29 to the left hand side of the motor piston 10, oil on the other side exhausting through line 13. To reduce pitch oil under pressure is supplied to the line 13 from which it branches to act on the right hand side of the piston 10 and to move the pitch lock valve 17 against the action of its spring 22 so that oil from the left-hand side of the piston can exhaust through said valve into line 14. The port 32 of the reduction gearing driving the propeller shaft 30 is connected to hydraulic piston and cylinder units 33 forming port of a torquemeter so that when negative-torque is experienced, i.e. when the propeller windmills and drives the engine, the port 32 moves clockwise, thus tripping a lever 25 to raise a spring- loaded spill valve 23 which connects the fine pitch line 13 with a low pressure line 24, thereby relieving pressure on the valve 17. The spring 22 then closes said valve, forming a hydraulic lock in the motor cylinder so that fining of the propeller pitch with consequent increase in windmilling drag, is prevented. In another embodiment the spill valve is replaced by a multi-purpose increase pitch valve and the system includes main control, servo, and negative-torque signal valves so arranged that with the onset of negative-torque the lock valve 17 closes as in the first embodiment but the coarse pitch line is placed in direct communication with the delivery side of the governor pump. The propeller moves to a coarser pitch, the windmilling and the negative-torque are reduced, and the propeller is returned to the control of the main control valve. Specification 814,844 is referred to.
