Title: Plunger or piston pump having plungers or pistons which are  opposed-acting
IPC: F15B1/02
Filed: 1973-10-16
Abstract: 1446234 Reciprocating pumps K H THOMAS [trading as LANGEN & CO] 16 Oct 1973 [25 Oct 1972] 48147/73 Heading F1A A pump for supplying two circuits, e.g. for a motor vehicle, comprises opposed-acting pistons 5, 6 delivering through lines 14, 17 to circuits 15, 18, change-over valves 22, 23 being responsive to delivery pressure so that when a predetermined circuit pressure is exceeded the valves connect the pumping chambers to a by-pass line 21 connected to the respective circuits by check-valves 26, 27, so that if circuit 15 reaches its predetermined pressure before circuit 18 valve 22 is operated so that piston 5 delivers to circuit 18, via valve 27, with piston 6, and when both circuits are at their predetermined pressure both valves 22, 23 are operated and the pistons idle with their pumping chambers inter-connected by line 21. As shown, the pistons draw from a common reservoir 12. In Fig. 2 (not shown), the pistons draw from separate reservoirs via piston-controlled cylinder ports and the change-over valves function to change-over the reservoir connections to the cylinder ports when they connect the respective pumping chambers to the by-pass line, thereby preventing draining of both reservoirs if a leakage occurs in one of the circuits. Accumulators 19, 20 are provided. The change-over valves may have hysteresis devices to prevent excessively frequent change-overs.

A pick-up baler comprises a ram 2 mounted on rollers 16, 18 for movement along an arcuate path in a baling chamber (4), the framework of the baler being provided with connections 146 for mounting the baler on the implement carrying mechanism of a tractor. Further guide rollers 22, 28 engage the side and top respectively of the baling chamber, the roller 28 being mounted on a spring-biased arm 32 pivoted on a side 21 of the ram 2. The ram 2 is driven from a shaft 46 through reduction gears 48, a crank 50, connecting rod 52 and a universal joint 56. Material picked up by a reel 8 is fed by an auger 6 and feed fork 82 to the inlet (12) to the baling chamber 4. If the feed fork 82 is obstructed the drive to the pick-up reel 8 and auger 6 is interrupted by releasing a catch (126) which holds support arms (120) carrying a pulley (72). The catch (126) is connected through a Bowden cable (116) to a rod 96 which guides the movement of the feed fork 82. When the catch 126 is released the arms (120) and pulley (72) move to the dotted line position seen in Fig. 5 (not shown) and a drive belt 66 for the reel 8 and auger 6 becomes slack. Modifications.-The path of the ram 2 may be parallel instead of at right-angles to the path of the baler. The extension (138) of the bale chamber may be horizontal instead of inclined. The ram may have an additional side roller. The top roller 28 may be replaced by pads of hard wood &c. The auger may be replaced by an additional feed fork or by chains with prongs. The drive for the pick-up means may include shafts and sprockets, the overload trip including a clutch.

In a reduction gear having intermeshing pinions 30, 50, one of the pinions 30 has resilient teeth 64 which are circumferentially wider at their tips than the spaces between the roots of rigid teeth 52 on the other pinion 50 whereby the resilient teeth 64 are deformed into the spaces between the teeth 52 to reduce backlash. As shown in an adjusting drive for a cam 54, the pinion 30 is freely rotatable on a driving eccentric 28 and meshes fixed and driven ring gears 22, 50 having differing numbers of teeth 42, 52. Manual rotation of a disc 60 fast with the eccentric 28 causes circumferential adjustment of the cam 54 relative to the ring gear 22 and a shaft 34. In Figs. 4 and 5 (not shown), two adjacent cams (154, 254) engage a common cam follower (74) on an arm (72) and are adjustable relative to a shaft (134) by gear arrangements similar to the above to alter the combined cam profile. In Fig. 9 (not shown), a reduction gear of the above type is arranged between an electric motor and a driven shaft. The resilient teeth 64 may, as shown, be integral with the pinion hub 30 or may Figs. 7 and 8 (not shown), be individually secured to a rigid hub (88). The teeth may, Fig. 6 (not shown), have central apertures (84) which assist the tooth deformation. The resilient teeth may be made of a urethane elastomer and the rigid pinion may be metal or made of a rigid plastics such as acetal resins.

Abstract: 1,199,047. Laying pipes. WERNER CORNELIUS K.G. 6 Nov., 1967 [11 Feb., 1967], No. 50306/67. Heading F2P In a method of laying a drainpipe, consisting of a perforated flexible pipe of synthetic material, wherein the pipe is paid out from a supply reel 5 mounted on an endless track vehicle 1 as the vehicle is advanced and the pipe is laid at the required depth and angle of slope from an outfall ditch by a plough 9 which is adjusted to the desired depth during laying by a motor 10, a theodolite 21 positioned at the outfall ditch is adjusted to a horizontal direction in which it is desired to lay the pipe, the plough is adjusted to the desired depth in the ditch, the theodolite is readjusted to give the desired angle of slope at which it is desired to lay the pipe, a sight mark 14 movable with the plough is adjusted to align with the graticule of the theodolite, and remote control of the motor 10 is effected to adjust the plough depth as the pipe is laid to maintain the sight mark constantly in the graticule of the theodolite. In this manner, the pipe is laid at the desired angle in the ground regardless of any surface undulations over which the pipe-laying vehicle may traverse. As shown, the plough is fixed to carriage 8 which is slidably adjusted in a framework 2, 7 by an hydraulic double-acting piston and cylinder motor 10. The piston/cylinder motor hydraulic supply is through a slide valve 12, Fig. 3 (not shown), which is actuated by an electromagnet 13. The magnet may be radio-controlled by an observer at the theodolite. Alternatively, as shown, the magnet is actuated by an observer at the theodolite through a switch 22 and a cable 24 run off from a drum 23 mounted on the vehicle, the amount of cable run-off during laving also giving an indication of the pipe length laid. The framework is pivotally mounted at 3 on the vehicle and is maintained in the vertical plane regardless of any vehicle pitching movement by a double-acting hydraulic motor 4. The motor 4 is fed through a control slide valve operated by another electromagnet (not shown). This electromagnet is actuated when a plummet 16, Fig. 4 (not shown), suspended in a liquid engages one of two contacts 18, 19. The pipe is guided in a guide pipe 28, Fig. 6 (not shown), at the rear of the plough. Also an extension guide tube 26 may be pivoted to the end of the guide pipe to reduce effects due to varying the depth of the plough. The pipe may be previously wrapped with filter material, such as peat mats or glass fibres. Alternatively, Fig. 5 (not shown), cellular or other coarsegrained material may be blown from a container on the vehicle into the ditch formed by the plough through a further tube 29 at the rear of the plough by a blower mounted on the vehicle.
