Patent GB-1305775-A (GB)
IPC: F02M41/12
Filed: 1970-05-01
Abstract: 1305775 Fuel injection pumps ROBERT BOSCH GmbH 1 May 1970 [2 May 1969] 20989/70 Heading F1A In a fuel injection pump having a spill passage 14a, 14b opened by lifting of a spool valve 12 by fuel pumped by an auxiliary piston 15 movable with the injection piston 3 and closed by a spring 26 which has to force the fuel back through an adjustable throttle 23, 25, the maximum crosssection of the throttle is limited to a smaller value when a vehicle driven by an engine fed by the pump is driven in a pre-selected gear e.g., top gear. Since the maximum crosssection of the throttle determines the maximum engine speed, the engine is limited to a lower maximum speed when driving through the preselected gear than when driving through any lower gear. Adjustment of the throttle crosssection is effected by rotating a control shaft 41 connected through a spring drive 42 to a control spool 24. When the pre-selected gear is engaged an electro-magnet 32 is de-energized whereby a spring 36 lifts a pin 34 into an arcuate recess (31) in a flange 30 on the spool 24. Thus rotation of the shaft 41 eventually causes the pin 34 to abut the end of the recess (31) whereafter further rotation of the shaft 41 causes tensioning of the spring without rotating the spool 24. In an alternative, Fig. 2 (not shown), the electromagnet controls the axial position of a plunger slideable in a w-axial bore (25') in the control spool (24') thereby to control a second throttle in series with the throttle 23, 25. When the pre-selected gear is engaged the second throttle over-rides the throttle 23, 25 which is unaffected by the  electromagnet.

Title: Cyclopentanophenanthrene compounds and a method for the preparation thereof
IPC: C07J71/00
Filed: 1952-08-21
Abstract: The invention comprises 22-isoallospirostan-3b -ol-11-one, and a process for the production of a spirostan-3-ol-11-one by reducing the corresponding spirostan-3,11-dione with hydrogen in the presence of a hydrogenation catalyst, e.g. Raney nickel which has been previously reduced.  The reduction may be carried out in a solvent, e.g. ethanol.  In the example, 22-isoallospirostan-3b -ol-11-one is prepared by hydrogenating 22 - isoallospirostan - 3,11 - dione in the presence of reduced Raney nickel.  22 - Isoallospirostan - 3,11 - dione is prepared by oxidizing 22-isoallospirostan-3b ,11a -diol in acetic acid with chromic acid.

Title: Improvements in or relating to electric elevator systems
IPC: B66B1/18
Filed: 1925-08-25
Abstract: 247,145. Waygood-Otis, Ltd., (Assignees of Lindquist, D. L., Dunn, E. L., and Larson, D. C.). Feb. 3, 1925, [Convention date]. Electrically - released switches; e l e c t r o magnetic switches. - Relates to switches for use in a push-button lift system. The retaining magnet for the push bottons 652 .. of a lift control comprises a rectangular coil 67, Fig. 3, arranged in iron channels 648, 649 and secured to an insulating base 650. The switches 652 .. 658 for the even floors are pivoted on a shaft 660 and their armatures 661 extend over the channel 649. The switches for the other floors also are mounted on the shaft 660, but their armatures extend over the channel 648. The button 665, Fig. 7, and contact lever 673 are pivoted on a pin 672 extending across an aperture in the armature 661. The lever 673 extends through a slot in the button, and is engaged by a spring 675. The upward movement of the armature is limited by the engagement of its pronged end 667 with the stop 670. When the button is pressed, the armature 661 and lever 673 are moved down together until the lever engages the stationary contact 677. The armature then moves alone until its outer end engages a flange of the channel 649, which forms one pole of a magnet and so retains the switch in closed position. When the coil 67 is de-enexgized, the spring 675 forces up the armature which on coming into contact with the projection 676 on the lever 673 opens the switch. The floor stop switches are mounted on the stop and signal panel 937. The frame 936 supports magnetic cores 939, 940, the former being for the closing coil 296 and the latter for the reset coil 310. The coils are retained in position by a plate 942 on which is mounted a pin 944 forming a pivot for the armature 946, which is extended upwardly to form an operating arm in which is slidably mounted the movable contact 304. The contact block 962 is mounted in a holder 961 adjustably mounted on the panel 937. A pivoted latching member 966 preferably of non-magnetic material is biased bv weights to turn counterclockwise. A projestion 972 on the member 966 co-operates with a lug 973 on the arm 974 of the armature 946 to hold the contacts in closed position. The armature 975 for the lower magnet is pivoted on a pin 964 between the arms of the member 966, and is formed with a lug 976 which carries an adjustable abutment screw 977. The weighted lower end 978 of the armature tends to maintain the armature in unattracted position with the screw 977 abutting against a projection 980 on the frame. A lug 981 on the member 966 is in the path of the weight 978 and is struck as the armature is attracted. The floor signal switches are similar in construction to the floor stop switches, but the arms of the latching member are extended below the weight 978 and carry a movable. contact similar to the contact 304, Fig. 27. A lug on one of the arms is engaged by the weight.

Title: Power assisted braking system
IPC: B60T8/40
Filed: 1965-05-20
Abstract: 1,085,153. Hydraulic brakes. R. DE MARCELLUS. May 20, 1965 [July 16, 1964], No. 21510/65. Headings F2E and F2F. In a power-assisted braking system for a motor vehicle a pedal operated master cylinder 11 supplies hydraulic fluid under pressure via lines 12 and 15 through a housing 14 to the wheel brake cylinder 17 of a vehicle wheel 20, the latter being provided with a mechanical connection indicated by the dashed line 22 to one of the gears of a gear-wheel pump 21 provided within the housing 14 which provides the source of power assistance. When the vehicle travels in a forward direction the gears of the pump 21 cause fluid to flow in the primary circuit as indicated by the arrows B. Upon the application of pressure to the brake pedal 10 the master cylinder 11 transmits hydraulic pressure through the line 12, housing 14 and line 15 and at the same time creates a pressure on the surface 25a of a piston 25 to drive this piston downwardly against the action of a spring 29 and thereby restrict the flow of fluid in the primary circuit across a slotted aperture 32 in a partition member 23 to increase the hydraulic pressure on the output side of the pump 21 and in the line 15 to the wheel brake cylinder 17 so that the amount of braking force generated is related to the amount of change in area of the aperture 32 which is controlled by the amount of force applied to the brake pedal 10. In order to prevent unnecessarily high pressures on the output side of the pump when the vehicle is travelling at high speeds a pressure relief valve 33 and an adjustable pressure reducer valve 35 are provided. Wheel locking is prevented since as soon as the wheels of the vehicle slow down, the pump 21 is slowed correspondingly.
