Abstract: 1517399 Dispensing articles EGG SALES PROMOTION Inc 13 Nov 1975 [6 Dec 1974] 46864/75 Heading B8U A deck of coupons 28 is disposed on an inclined surface 14, each coupon 28 being dispensed therefrom into a respective container 26 mounted on a conveyer 24 as each container 26 passes the dispensing apparatus. The deck is retained on the surface 14 both by a support member 30 whose position is adjustable relative to the body 10 of the apparatus and by a slidable weight 32, and a drive wheel 62 which projects through an opening 36 in the member 30 is effective on rotation, due to its engagement with the foremost coupon in the deck, to remove that coupon from the deck, the coupon then passing through a space 33 between the member 30 and the surface 14 and then between contra-rotating rollers 68, 70 to the associated container 26. Rotation of the roller 68 and the drive wheel 62 is effected by an electric motor which drives a drive sprocket (88) and thus a chain (94), Fig. 4 (not shown), the latter passing about a drive wheel sprocket 90 and a roller sprocket 92 mounted respectively on the drive shafts 63, 76 of the drive wheel 62 and roller 68, the roller 68 rotating the roller 70 due to their engagement, and the roller 70 is urged into engagement with roller 68 by a spring 84. Normally the drive wheel 62 is prevented from rotating by means of a notched arm (104) which engages a notch (114) formed in a clutch plate 98 fixed to the drive wheel shaft 63. When a container 26 approaches the dispensing apparatus a projection 118 associated with the container actuates a microswitch 116 which in turn momentarily actuates a solenoid (110) to raise the arm (104), and a clutch disc 96 fixed to the drive wheel sprocket 90 then frictionally engages the clutch plate 98 under the action of a compression spring 100 to drive the shaft 63 and thus the drive wheeel 62 counterclockwise in Fig. 1 to effect the dispensing of a coupon. Due to the momentary actuation of the solenoid (110) the arm (104) rides on the clutch plate 98 until the latter has completed one full revolution and the notch (114) is engaged by the arm (104). During this single rotation of the drive wheel 62 the high-friction material (64) of a first portion of the wheel 62 (Fig. 2, not shown) is effective to remove the foremost coupon from the stack.

Abstract: 1411115 Automatic voltage control WESTERN ELECTRIC CO Inc 18 Oct 1972 [19 Oct 1971] 47893/72 Heading G3R [Also in Division H2] A D.C.-D.C. converter including an output transformer is regulated by a feedback path including a pulse generator. The ends of the feedback path are D.C. isolated and the width of the pulses is dependent on the difference between the D.C. output voltage and a reference voltage. As shown, a converter comprises an inverter 1, rectifier 2 and regulator 3, and is formed on two integrated circuit chips A, B with transformer coupling. The inverter is formed by switching transistors 10, 20 controlled by a switching circuit 50, the operation of which is regulated by a clock source 51 and modified by feedback from a pulse transformer 55. The circuit 50 comprises cascade-connected flipflops and NOR gates (111-124), Fig. 3 (not shown). Main output winding 16 of transformer 15 is coupled to a load 90 and to rectifying transistors 30, 40 which have current transformers 33, 38 in their collector circuits. A winding 7 provides base drive current, and a winding 8 produces positive turn-off under the control of a transistor 35 switched by circuit 50. Diodes 9, 19 provide paths for flyback current induced by filter inductor 49, and the arrangement is suitable for high frequency operation. A voltage comparator 65, which may be a differential amplifier (139), Fig. 3 (not shown), receives inputs from a reference source 70 including a breakdown diode, and a lead 66 connected to the load 90. The resulting error signal modulates the width of a pulse produced by a generator 60 synchronized by the unfiltered output voltage 61 and comprising a monostable multi-vibrator with cross-coupled NOR gates (131, 132). The output pulse is differentiated by coupling transformer 55 to produce positive spikes which switch logic elements in circuit 50 to regulate the converter operation.

Abstract: 1329715 Brake valves; hand brakes; valves ROBERT BOSCH GmbH 9 Oct 1970 [10 Oct 1969] 48049/70 Headings F2E, F2F and F2V An actuator piece 2 of a valve assembly 1 on a vehicle is operable by a hand brake lever 25 and a cable 24, the assembly 1 comprising a first valve with a movable valve seat 11 and a closure member 10, which valve seat 11 is movable by the actuator piece 2 to engage the closure member 10 and close the valve 10, 11, further movement of the actuator piece 2 after it has moved through a predetermined distance 'a' opening a second valve 16, 17 by lifting a closure member 17 (which may be the same closure member as member 11, see Fig. 2) off a fixed valve seat 16. The arrangement allows cable 24 to slacken without the brake releasing when the vehicle is parked. As shown, valve 10, 11 closes to cut off a port 12 from atmosphere, and valve 16, 17 opens to connect the port 12 with a port 20 to a source of compressed air. The valve assembly 1 may also operate to control spring-applied fluid pressure released cylinders, and in this case the valves are interchanged. In Fig. 1 the assembly is shown in the released position and to apply the brakes the lever 25 is moved clockwise and locked by interaction of a stop tooth 28 and toothed segment 26 via the cable 24 and a T-shaped lever 22, the piece 2 is caused to move downwardly, to close the outlet valve 10, 11. The distance 'a' is then covered by the closure body 10 of valve 10, 11 with compression of a spring 15 until the closure body 10 abuts base 14<SP>1</SP> of a sleeve 14 whereby closure body 17 of valve 16, 17 is lifted from its seat 16 so that compressed air passes from port 20 which is connected by a pressure line to a compressive to port 12. The valve assembly 30 of Fig. 2 is actuated as in Fig. 1 to cause downward movement of an actuating piece 39. The outlet valve 11, 17 is first closed and as valve spring 19 is stronger than spring 37 a sleeve 35 moves down through distance 'a' until a boss 35<SP>1</SP> thereof abuts a disc 34. The stem 32 is then moved down to overcome spring 19 and open the inlet valve 16, 17.

Filed: 1962-12-20
Abstract: 986,172. Hydrostatic transmissions. BETEILIGUNGS-UND PATENTVERWALTUNGSGESELLSCHAFT. Dec. 20, 1962 [Dec. 23, 1961], No. 48169/62. Heading F2C. [Also in Division F1] An hydraulic transmission comprises a piston-and-cylinder type pump or motor and a vane-type motor or pump having axially slidable vanes. The vane-typeunit, a developed view of which is shown in Fig. 4, comprises a rotor formed by a bush 3 secured to side members 4, 5 by tie rods 6 and fast with a driving or driven shaft 1, 1<SP>1</SP>. The side mem bers 4, 5 are mounted in a stationary housing 9 in which vanes 10 are axially slidable, the vanes 10 having sealing strips 12 at each end which are pressed by springs 13 into engagement with surfaces 7, 8 of the side members. The surfaces 7, 8 have a sinusoidal form and co-operate with the vanes to form chambers 15, 16, the chambers 15 communicating through passages in the housing 9 with a cylinder of the piston and cylinder unit, and the chambers 16 communicating with a second cylinder of this unit. The vanes 10 are formed with pins 14 engaging a sinusoidal groove in the bush 3 to impart axial movement to the vanes as the rotor is rotated so that the sealing strips 12 are relieved from the duty of imparting reciprocation to the vanes. In operation as the piston in the cylinder connected to the chambers 15 moves to increase the pressure in these chambers, the other piston will move in the opposite direction to transmit torque. In order to substantially balance the tilting moment exerted by pressure on the exposed sides of the vanes, passages lead from each side of a vane at each end to the opposite side slightly inward of the end and terminate in grooves 17, the pressure in which reacting against side walls of the slots in the housing 9 in which the vanes are housed counteracts the effect of pressure on the exposed end of the vane. In a modification the pins 14 and the co-operating guide groove in the bush are omitted, and the end of the vanes are so shaped that they contact the surfaces 7, 8 to reciprocate the vanes independently of the sealing strips 12.

Title: Drilling boreholes in the earth with automaitc optimization of the penetration rate
IPC: E21B19/08
Filed: 1973-10-18
Abstract: 1441005 Boring earth &c INSTITUT FRANCAIS DU PETROLE 18 Oct 1973 [20 Oct 1972] 48675/73 Heading EIF [Also in Division G3] In a system for automatically optimizing the penetration of a drill bit 5 suspended from a drill pipe 7 and rotated by a motor 6 whose torque decreases with rotational speed the actual penetration rate is calculated from a measurement of drill pipe tension at least, while the weight on the bit is cyclically varied through a range which includes the maximum penetration rate. It is explained that as the weight on the bit is increased by feeding the drill pipe down from the surface, the penetration rate increases to a maximum and thereafter decreases due to overloading of the bit motor 6. The penetration rate Va is calculated according to a given formula by an undisclosed digital computer 13 from measurements of pipe tension T (from a strain gauge 15), length of pipe in use (from a selsyn 16, 17 and pulse converter), linear speed of the pipe at the surface (from a second selsyn 20, 21) and the elasticity α of the pipe, which is determined by the computer from measurements made while the bit is not rotating. The calculation of Va is carried out periodically at a frequency corresponding to that of cyclic variations in pressure Ps caused by a mud pump (not shown), the value being stored at 27 and updated as it increases, (not if it decreases). Va is also used as a reference value for retroactive control of a motor 10 which lowers the pipe, either as shown for a flexible pipe or by a winch gear (Fig. 3a, not shown) for a rigid pipe. When the maximum penetration rate is reached (i.e. no increase in store 27) the weight on the pipe continues to be increased (by feed motor 10) until the penetration is a prescribed value Y less than the maximum. As shown, a clutch 11 is then disengaged to halt the pipe feed and the weight on the bit is progressively lessened (i.e. the bit is more fully supported by the pipe) resulting in an increase in pipe tension. When this has_increased by a preset amount #T the clutch H is re-engaged and the cycle repeated. Instead of clutch 11 the feed motor speed may be controlled as a function of Va, set at 26 to produce increasing and decreasing penetration rates controlled as before. Changeover from feed to "no feed" may alternatively be effected in response to a change in tension from that which occurred when Va was maximum.
