Title: Methods for the manufacture of asphaltic bitumen blocks
Inventor: KROLIKOWSKI STEFAN RONALD
IPC: C10C3/18
Filed: 1956-01-09
Abstract: 788,029. Moulding blocks of bitumen. SHELL RESEARCH, Ltd. Jan. 9, 1956, No. 679/56. Class 87(2). A layer of asphaltic bitumen, formed at a temperature 25‹C.-100‹C. (e.g., 70‹C.) above its softening point is penetrated at that temperature by shape-forming partitions which have been treated with a releasing agent, cooled, and the partitions removed to leave bitumen blocks. A suitable surface on which to form the layer is concrete or steel plating. The partitions, which may have knife edges, and are preferably of mild steel or aluminium alloy, are pressed through the bitumen layer either as separate strips or as a lattice structure. They are moved mechanically or manually and may be guided by rails or by slots in the walls which confine the layer, and before withdrawal they may be subjected to hammering to loosen them. When they are pressed through the layer separately to form intersecting divisions the upper edges of the strips which are first pressed through may be slotted and the lower edges of the strips that are pressed through the layer subsequently, transversely to the former strips, may also be slotted, the slots registering to allow the latter strips to travel the full distance. Zig-zag strips with right-angle bends may be used, the alternate corners of adjacent strips being in contact. Fig. 5 shows three strip structures which co-operate to divide the bitumen into blocks. Cooling after the cutting operation, preferably to 60‹ below the softening point of the bitumen, may be accelerated by air blasts or by cooling coils; The releasing agent may be added to the partitions by spraying, brushing or immersion. This agent is desirably a substance with thixotropic properties. Suitable substances for releasing agents are aqueous solutions or suspensions of an alkali metal silicate, or of an alkali metal soap of a fatty acid, e.g., a potassium soap, or of metallic oxides or hydroxides, or of alginates, or of secondary alkyl sulphates. Petroleum wax emulsions may be employed as releasing agents, either alone or mixed with the above. Hygroscopic or deliquescent materials may be included. Percentage mixtures of suitable releasing agents are given. The bitumens may be naturally occurring asphaltic bitumens or prepared by treatment of residual petroleum oils. The blocks also may be treated with the releasing agent to prevent them from sticking together. Specification 28694/10 [Class 87(ii)], is referred to.

Title: Improvements relating to d.c. dynamo electric machines controlling the supply to electric motors and other variable loads
IPC: H02P7/34
Filed: 1938-01-10
Abstract: 509,884. Exciting dynamos. ENGLISH ELECTRIC CO., Ltd., BINNEY, E. A., CORNER, H. S. POUND-, and SEDGFIELD, H. B. Jan. 10, 1938, Nos. 718/38 and 623/39. [Class 35] [Also in Group XXXVII] A motor-generator set comprises a machine excited by a shunt field winding in series with which winding is an exciter having three fields, one energised in accordance with the armature current of the machine, another separately excited, and a third connected across the exciter armature, the exciter being mechanically coupled with the machine, and the set operating to maintain a predetermined current in the load circuit. The machine 6 is driven by a motor 1 and controls series motors 7, 7b by first bucking and then boosting the voltage of the suppiy. The motor 1 is first run up to speed and the motor circuit made by closing a switch 11. The field 6a of the machine 6 is thus excited and builds up a voltage equal and opposite to the supply voltage. To accelerate the motors a switch 8 is closed, and subsequently the field 5b of the exciter 5 energised by closing a switch 13. The voltage of the exciter reduces the excitation of the machine 6, and the motors accelerate, the motor current flowing through the exciter field 5a and setting up a field opposing the field 5b. The motor current is maintained constant by the balancing action of the windings 5a, 5b, the value being determined by a regulator 5c for the field 5b. As the motors accelerate the field 5a is reduced and the exciter voltage effects a decrease of the excitation of the machine 6 which decreases the voltage applied from its armature to its field 6a and further reduces the excitation. The action continues and the motors 7, 7b accelerate until the voltage of the machine'6 6 is zero. The action is allowed to continue while the machine 6 builds up a voltage equal to the line voltage. The exciter shunt field 5d may assist or oppose the field 5a in maintaining the motor current, and it may assist during the bucking and boosting control of the motors, while opposing during excitation of the motor fields from the machine 6 after the motors at full voltage have been transferred to the external source. A series winding may be added to the exciter 5. A resistance 10 in the circuit of the field 6a may be controlled by a relay to compensate for the difference in the action of the set during bucking and boosting operations. The driving motor 1 may be arranged so that its armature reaction causes changes in speed which assist in maintaining the motor current during boosting control. The series winding of the motor 1 may be in circuit for the boosting control only, and this motor may have a field energised from the armature of the machine 6 to strengthen the motor field during bucking control and weaken it during boosting. Alternatively this additional field may be connected for boosting only. Specifications 485,312, 509,041, 509,138, 509,239; [both in Group XXXVII], and 509,884 are referred to.

Title: Improvements in or relating to packing cups for fluid pressure pistons and the like
IPC: B60T11/16
Filed: 1943-01-14
Abstract: 562,872. Piston packing. BENDIX AVIATION CORPORATION. Jan. 14, 1943, No. 740. Convention date, Feb. 21, 1942. [Class 122 (i)] A piston cup packing is provided with oblique grooves 40 in the outer periphery, whereby fluid passing through the grooves tends to rotate the packing. The inclined grooves may extend into a circumferential groove 39. As applied to a hydraulic brake master cylinder piston, passage of fluid past the packing during the return piston stroke rotates the packing and thus presents a new surface to the breathing port in the cylinder wall at each stroke and so equalizes wear of the packing. Specification 318,596, [Class 122 (i)], is referred to.

Title: Improvements in or relating to electrical circuit arrangements for performing invert operations
IPC: H03F1/08
Filed: 1966-01-07
Abstract: 1,099,848. Transistor switching circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 7, 1966 [Feb. 26, 1965], No. 782/66. Heading H3T. In a switching circuit having negative feedback and tending to produce unwanted oscillation, a further negative feedback path is made effective by the output voltage so as to oppose unwanted oscillation. As shown, logic signals at 21 are coupled via an AND gate 20 and diode 25 (which may be part of an OR gate) to an emitter follower 10 feeding an amplifier 11. Feedback via anti-saturation diode 38 tends to produce high frequency oscillation. This is prevented by resistor 33 which introduces Miller effect, thus delaying the response when the input is rising, the Miller effect being inhibited by diode 40 becoming conductive when the input is falling.

Title: Improvements relating to aircraft
Inventor: WILDE GEOFFREY LIGHT
IPC: B64C29/00
Filed: 1959-01-08
Abstract: 901,873. Vertical take-off aircraft. ROLLSROYCE Ltd. Jan. 7, 1960 [Jan. 8, 1959], No. 812/59. Class 4. An aircraft has a plurality of vertical lift engines 11, and deflecting means which include guide vanes which, when the deflecting means has been moved to its operative position, are spaced from one another stepwise longitudinally of the aircraft, each guide vane projecting beyond and in partially overlapping relationship relative to the preceding guide vane when considered in a direction rearwardly of the aircraft, the deflecting means being adapted, when in its operative position, to deflect air into each engine at least when the aircraft is moving forwardly. The aircraft comprises an engine bay 12, in which are mounted a plurality of engines 11, a grid 15 movably mounted within the bay 12 and provided with a plurality of deflector vanes 16, jacks 24 for moving the forward end of the grid 15 to a first open position, Fig. 4, in which, during forward flight of the aircraft, air is deflected by the deflector vanes 16 into the intakes of each of the vertical lift engines 11, and jacks 25 for moving the rear end of the grid to an open position, Fig. 2, in which, during vertical flight, unimpeded flow of air to the engines is ensured, all jacks 24, 25 being retracted during normal forward flight of the aircraft to bring a closure panel 19 into the plane of the aircraft's upper surface. The panel 19, which, when open, acts as an air scoop, is connected fore and aft by links 20, 21 to the rods 22, 23 of the air-operated jacks 24, 25. In order to start the engines 11 during forward flight, the scoop member 19 and the grid 15 are raised by the rods 22 to the position shown in Fig. 4. Ambient air will be trapped within the scoop member 19 and will be directed by the arcuate vanes 16 and the honeycomb grid 26 into the intakes of engines 11 to permit their lifting. When engines 11 have been lit, rods 23 are gradually raised until the position shown in Fig. 2 is reached to ensure maximum air intake. The exhaust gases from the engines 11 are directed downwardly through doors, not shown. In an alternative arrangement, Figs. 6 and 6b (not shown), substantially triangular section vanes are pivotally mounted in longitudinal walls of the engine bay, each vane projecting vertically above the vanes forward of it. In yet another arrangement, Figs. 7 and 7b (not shown), two retractable flaps, mounted at the forward end of the engine bays, impart vertical movement to the air flowing past them, the air then flowing over pivotally mounted vanes, which lie wholly within the bay, each vane being longer than any of the vanes forward of it.

Patent HK-74385-A (HK)
Title: Coin testing apparatus
Inventor: DEAN ROBERT
IPC: G08B1/08
Filed: 1985-10-03
Abstract: A coin testing apparatus comprises transmitting and receiving coils (14) and (15) on opposite sides of a coin passageway (11). The transmitting coil is connected to high and low frequency oscillators (16) and (17). The output of the receiving coil is separated into the high and low frequency components by a high pass filter (21) and a band pass filter (22). In the high frequency channel the signal is amplitude controlled by a voltage controlled amplifier (23) rectified by a rectifier (24) and smoothed by a long time-constant circuit (26). The initial rise in level caused by a coin entering between the coils (14) and (15) is detected by an instantaneous level change comparator (32) which responds to the rate of change of signal level at the output of the long time-constant circuit (26) becoming equal to preset threshold and causes a normally closed switch (27) to be opened. When the switch (27) is closed a comparator (31) compares the signal with a reference value from a source (30) and adjusts the gain of the amplifier (23) until the signal corresponds to the reference value. Upon the arrival of the coin the switch (27) is opened and a long time-constant circuit (28) causes the gain of the amplifier (23) to be maintained at the level before the arrival of the coin. A window comparator (33) compares the difference in voltage with voltage ranges for acceptable coins. A similar arrangement is provided in the low frequency channel but with two differences. The switch (27) in the low frequency channel is operated by the same instantaneous level comparator as is used for the high frequency channel and instead of a rectifier (24) a novel sample and hold technique is used for providing a d.c. signal from the output of the amplifier (23).

Title: Fare receiving device
Inventor: FUKUDA TOMIO
IPC: G07B15/00
Filed: 1988-01-06
Abstract: PURPOSE:To eliminate the counting and the repaying of small change, to execute efficiency, and to improve efficiency and operability by repaying change to a user by recording the change on a prepaid amount ticket instead of repaying the change to the user in cash. CONSTITUTION:A result obtained by comparing the toll of a toll highway with the balance remaining on the amount ticket by a comparing means 1, namely, shortage information to indicate that the toll of the toll highway is more than the balance remaining on the amount ticket and a shortage exists, is supplied to an operation control means 3. While the operation control means 3 requests the user to pay the amount to supply the shortage according to the shortage information, the operation control means 3 controls a balancing processing for a calculating means 5. The calculating means 5 calculates the shortage by subtracting the balance of the amount ticket from the toll of the toll highway and calculates the balanced amount by subtracting this shortage from the supplied amount supplied and paid by the user, this balanced amount is supplied to a supplied amount recording means 7 and recorded on the amount ticket as the change. Thus, the counting and the repaying of the small change can be unnecessary, the efficiency can be executed, and the operability can be improved.
