Title: Improvements in or relating to motor vehicle brake systems
IPC: F16D57/04
Filed: 1965-02-08
Abstract: 1,040,194. Fluid pressure brakes; hydrodynamic brakes. H. TEVES, E. A. TEVES and M. TAUSEND, [trading as ALFRED TEVES MASCHINEN - UND ARMATURENFABRIK KOMM. GES.]. Feb. 8, 1965 [March 25, 1964], No. 5320/65. Headings F2E and F2F. A motor vehicle braking system includes an hydrodynamic retarder 1 disposed on a shaft 32 for the vehicle drive and hydraulically actuated friction brakes 5 operated by a master cylinder 3 acting through a booster 4, the systems being interconnected by means of a differential pressure valve 2 which is under the control of the pressure differential in the hydrodynamic retarder 1. When the master cylinder 3 is actuated, hydraulic fluid flows from the chamber 9 of the valve 2 and then through an open passage 10 in the piston valve 11 into a chamber 12 whence it flows through a line 13 to a retarder operating valve 6 to supply hydraulic fluid from a reservoir 7 to the retarder 1. At the same time fluid flows from the chamber 12 via a line 14 to the control valve 15 of the booster 4 so that the hydrodynamic retarder and the friction brakes come into operation simultaneously. The low-pressure side 19 of the retarder 1 is normally at the same pressure as the highpressure side 18 until the charging reservoir 7 has filled the retarder 1, whereafter there is a pressure differential corresponding to vehicle deceleration. The differential pressures are transmitted from the low-pressure side 19 directly to the surface 24 of a diaphragm 23 acting upon a valve rod 30. Pressure from the high-pressure side 18 of the retarder 1 passes indirectly via a line 29 to the diaphragm surface 27 and the valve head 31 tends to close the passage 10 in the piston valve 11 as long as the vehicle continues to decelerate. Pressure medium in the retarder 1 flows from the highpressure side 18 via a line 21 to a cooler 8 and thence back to the low-pressure side 19 via a line 22.

Title: Improvements in or relating to nailing machine feed mechanisms
IPC: A43D71/00
Filed: 1960-02-16
Abstract: 904,776. Nailing-machines. YOUNG MACHINERY CO. Inc., W. J. Feb. 16, 1960 [Feb. 20, 1959], No. 5540/60. Class 89 (3). [Also in Group XXX] A nailing-machine feed mechanism comprises parallel inclined shoots 11, Fig. 1, to receive the nails supplied from a hopper 6, and an elongated bar 76 reciprocable across the top of the shoots and positioned to engage with its edge 99 the lowermost nail in each shoot. The bar is moved longitudinally only against a spring 81 to align spaced recesses with the shoots, thereby releasing the lowermost nails which pass into a part 110 turned by means 115, in timed relation to the nailing machine, to drop the nails into supply tubes 116. During this movement of the bar, the second lowermost nails are held by spring- loaded pawls 75 pivoted on the bar. The shoots are stepped beneath the bar. The hopper is fixed to a shaft 9 and is oscillated about the shaft axis by reciprocating arm 42<1> pivotally engaging the bottom of the hopper. A flap valve 35 in the hopper limits the quantity of nails entering the forward part 41 to engage grooves 42 therein and be moved by the oscillations through openings 43, adjustable by a plate 44, into grooves in shaft 9 and thence into the shoots. Bars 52 are slidable over the openings by levers 50 on a shaft 49 turned by arm 64 engaging abutment 69 when the hopper is in its substantially horizontal position to free any jammed nails, and closed by springs 60. The bars in the closed position leave room for nails in grooves 42 to pass through openings 43. Shoots not in use are closed by removing the levers 50 and reversing the bars 52. Specification 904,777 is referred to.

Title: Means for regulating the phase of the grid voltage in ion valves
IPC: H02M1/04
Filed: 1934-02-20
Abstract: 438,869. Converting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. Feb. 20, 1934, No. 5600. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 25, 1934]. [Class 38 (ii)] Grid potential of adjustable phase for regulating an arc rectifier 2 is derived from a circuit containing impedances one of which is variable in magnitude. In one arrangement, Fig. 1, an inductance 8 and resistance 9 are connected in series across a supply transformer 6, and the dephased voltage appearing between the centre of the transformer winding and the point of interconnection of the inductance and resistance is supplied to the grids through a transformer 11. The inductance is varied by a saturating winding 12 energized in accordance with the voltage across the load 5. If desired a part of the drop across the cathode choke 4 may be included in the control circuit in order to compensate for the magnetic inertia of the inductance 8. In a modification, Fig. 3 (not shown), the input voltage is applied to the transformer 11 and the grids are connected to the transformer 6 thus reversing the phase displacement for variations in the same sense of the controlling voltage. In another arrangement, Fig. 4, phase displacement of the grid potential over a restricted range and with a small change in magnitude is achieved by connecting two inductances 17, 18, one of which is variable, across one phase of a three phase winding 16 and utilizing the dephased voltage appearing between the junction of the other two phases and the junction of the two inductances. Fig. 6 shows an alternative method of deriving a controlling voltage for automatic regulation. The voltage across the load 5 is applied to two parallel circuits, one comprising resistance 19 and the other comprising resistance 21 and a discharge tube 20. The saturating winding 12 for the regulating inductance is connected between the junction of the discharge tube 20 and resistance 21 and a tapping on the resistance 19 which is so adjusted that at the highest expected value of rectifier output voltage no current flows in the saturating winding 12. On decrease in output voltage the drop across the left-hand portion of the resistance 19 decreases whilst the drop across the discharge tube 20 remains the same. Thus current flows in the saturating winding 12 tending to advance the phase of the grid potentials and thus raise the output voltage. Compounding may be introduced by an additional saturating winding 27 energized from a shunt 26. In a further modification, Fig. 7 (not shown), a rectifier is regulated for constant current by connecting the saturating winding 12 in a circuit which is energized by the difference between a fixed voltage derived from an auxiliary rectifier and the drop across a shunt in the load circuit comprising resistance and inductance. Specification 412,773 is referred to.

Title: Power steering system affording emergency steering capability
IPC: B62D5/32
Filed: 1972-02-09
Abstract: 1315107 Power steering GENERAL SIGNAL CORP 9 Feb 1972 [5 March 1971] 6038/72 Heading B7H An hydraulically operated power steering system of the type having a closed centre steering valve 11 for controlling the flow of fluid to and from steering motor means 12, 13 and having a supply circuit 14 containing an accumulator 15 for storing fluid under pressure includes a main pumping unit 17 driven by the engine, first control means 19 which causes the main pump 17 to deliver fluid to the supply circuit 14 when the pressure in the supply circuit 14 drops below a first level, an auxiliary pumping unit 38 connected to at least one of the wheels of the vehicle so that it is driven when the vehicle is in motion, and second control means 19a which causes the auxiliary pump 38 to deliver fluid to the supply circuit 14 when the pressure in the supply circuit 14 drops below a second level, lower than the first level. This arrangement allows the vehicle to be steered in the event of a main pump or engine failure or when the vehicle is being towed. As described the main pump 17 is a constant displacement pump whose output 22 is connected to control device 19. The control device directs the pump output to the supply circuit 14 via check valve 25 if the pressure in the supply circuit 14 drops below, e.g. 2550 p.s.i. and directs the pump output to exhaust 18 via unloading valve 23 when the pressure in supply circuit 14 reaches 3000 p.s.i. The auxiliary pumping unit 38 includes a constant displacement pump 39 driven by the vehicle wheels and four check valve 41 to 44 which ensures that the pump output is always along line 45 regardless of the direction of movement of the vehicle. The second control device 19a is similar to the device 19 but connects the pump 39 to supply circuit 14 when the pressure is below 1785 p.s.i. and to exhaust via unloading valve 23a when the pressure is above 2100 p.s.i. The control device 19a also includes an unloading valve 46 which is opened when the pump 17 is operating, e.g. when the pressure in line 22 is above 100 p.s.i. Thus the auxiliary pump 38 only supplies fluid to the supply circuit 14 in the event of a main pump or engine failure or when the vehicle is being towed. In a modification (not shown) either the main pump 17 or both pumps 17, 39 are of the variable displacement type and supply of fluid to the circuit 14 is controlled by varying the displacement of these pumps according to the pressure in the supply circuit 44.
