Title: Control of the supply of electrical energy
IPC: H02J3/14
Filed: 1970-10-12
Abstract: 1314351 Programmed control of furnace supply INTERNATIONAL BUSINESS MACHINES CORP 12 Oct 1970 [20 Oct 1969] 48352/70 Heading G3N The supply of electricity to arc furnaces 20-22 is so controlled as to anticipate the change in the process occurring later in a demand period by an energy consumption control system 36. The furnace electrodes are individually controlled through mechanisms 23-25 by rheostats 26 set manually or automatically over lines 56-58 by the system 36. The total power consumed by the furnaces from a three-phase supply 27 is determined by a meter 28 and the individual power consumption is determined within the mechanisms 23-25 and signalled over lines 30-32 and accumulated in a monitor 35 of the system 36. The system 36 is controlled by a timer 42 responsive to arbitrarily timed external synchronizing pulses supplied by the generating concern on line 44, in dependence on demand billing. The timer signals, at intervals between the synchronizing pulses, the monitor 35 and an available energy determination circuit 45 containing a counter which is set to zero by a synchronizing pulse and incremented by pulses from the meter 28, and a register preset to the total amount of energy to be utilized in a demand period; the interval signal initiates a subtractor whereby is signalled on a line 49 the total energy available for the remainder of the demand period and is fed to a subtractor 50. At the same time a circuit 37 notifies the highest priority furnace to computers 40, 41 over lines 38, 39; computer 40 gates the data from monitor 35 for the highest priority furnace and determines the time remaining in the stage which is compared with the time remaining in demand period to determine the power consumption signal on a line 51 to the subtractor 50. The computer 40 also controls the bank of rheostats 26, through relays 55, to operate the priority furnace at its preferred output. The subtractor 50 determines the remaining energy in the period which is set into a divider 66, responsive to an output on a line of the low-priority computer 41 to derive the ratio of available energy for the lowpriority furnaces to the preferred value. The relays 55 are energized accordingly to operate the low-priority furnaces, by stretching the stages at less than their preferred power so that the total energy consumed during a demand billing period does not exceed the pre-set amount.

Filed: 1971-10-19
Abstract: 1357578 Engine control circuits ZAHNRADFABRIK FRIEDRICHSHAFEN A G 19 Oct 1971 [22 Oct 1970] 48650/71 Heading F1B [Also in Division F2] An automatic gear changing circuit is provided with a driver operated engine braking circuit so arranged that engine braking is rendered inoperative during gear shifting. A pump 14 and main pressure valve 18 actuate a pressure cylinder 1 to disengage an accelerator linkage and a cylinder 2 to disengage the clutch under the control of a release valve 4. Similarly an engine braking cylinder 6 and an engine acceleration cylinder 7 are controlled by a valve 10 operated at 25, 27, by gear change control members. An operation of the drivers engine braking switch 24 through electrical leads 23 change over valves 19, 20 are moved to position B thus actuating cylinder 1, to disengage the accelerator, and cylinder 6 to apply engine braking. If with engine braking applied gear shift is required valve 4 is moved to position A or B to actuate cylinder 2 to disengage the clutch while valve 10 is similarly moved to position A or B to apply pressure to the engine acceleration valve 7 and by pressure on a switch 21 disconnecting lead 22 to the change over valve 20 which then restores to position A releasing the engine braking cylinder 6 and thus allowing the cylinder 7 to produce engine acceleration. On completion of gear shifting valves 4 and 10 are restored to position B and engine braking is thus restored.

Title: Camera shutter mechanism
IPC: G03B9/18
Filed: 1976-11-24
Abstract: 1534083 Shutter mechanism SEIKO KOKI KK 24 Nov 1976 [25 Nov 1975] 48991/76 Heading G2A In a camera shutter mechanism, an opening member is spring-urged into the opening position, then a closing member is spring-urged into a closing position, the opening member controlling a pair of electrical contacts. Fig. 1 shows the mechanism in the charged position. A set of opening blades covers the aperture, and is moved by an opening member 2, urged clockwise by a spring 2b, but retained against movement by a detent 3. The other end of spring 2b is attached to a pin 6j on an actuating member 6. A set of closing blades, so placed as not to occlude the aperture, is moved by a closing member 4, urged clockwise by a spring 4b, but retained against movement by a detent 5. Both detents are spring-urged clockwise into the positions shown. A contact member 7 is mounted on the same pivot 2a as opening member 2. Member 7 is spring-urged anti-clockwise into the position shown in Fig. 1, in which it abuts against a stop 7f. In this position, a contact portion 7d is out of engagement with a contact 7e, the contacts forming part of an electrical circuit, e.g. for flash operation or for exposure control. The actuating member 6 is drawn upwards and to the left by a spring 6c, so that a step portion 6d latches against a pin 6e. To effect an exposure from the Fig. 1 position, detent 3 is disengaged from member 2. This pivots clockwise and causes the opening blades to uncover the aperture. In so pivoting, it also engages a pin 7c on member 7 which is also thus caused to pivot clockwise, so that contacts 7d and 7e are closed, so completing the electrical circuit (position of Fig. 2, not shown). After a predetermined time detent 5 is disengaged from closing member 4, which pivots clockwise and so causes the closing blades to move to a position in which they cover the aperture. As member 4 pivots clockwise, it slides over a step portion 6h of member 6, pushing it to the right, and so disengaging it from pin 6e. Member 6 can now be pulled upwards by spring 6c, position of Fig. 3, in the course of which stepped portions 6f, 6g engage members 2 and 7 and restore them to the Fig. 1 position. This movement of member 2 also restores the opening blades to return to the position in which they cover the aperture. To re-charge the mechanism, member 4 is caused to rotate anticlockwise until both members 2 and 4 are latched once more by the detents. At the same time member 6 is pulled down again, restoring it to the Fig. 3 position. A number of modifications of this basic arrangement are described.

[Also in Division E2] A length 15 of a pile fabric sheet material of a type having a surface of flexible resilient hooking elements 12, i.e. either hooks or loops, secured to a base in directions extending therefrom, the hooking elements 12 being characterized by the property that the pressing of a surface of hooks into face-to-face relation with a surface of loops results in a large number of loops engaging a large number of hooks, is joined to a second length 25 of sheet material by overlapping a marginal end portion of the second length 25 with a flat marginal end portion of the first length 15, the latter end portion being substantially free of the hooking elements 12 and joining the two end portions in interfacial adhesive contact. The pile fabric may comprise a firmly woven base having supplementary warp threads which form the elements 12. Alternatively the base may be a sheet of plastics material. Preferably, both the base and the elements 12 are made of nylon or other heat-settable material. The elements 12 are fixed or stabilized by heat setting or impregnation with resinous plastics materials, e.g. polyurethane, or both. The elements 12 are removed from the end portion of the length 15 by grinding or skiving and an adhesive deposit is applied to this end portion. If the base is of nylon and polyurethane has been used as an impregnant, then a synthetic rubber resin, solvent type adhesive may be used. This adhesive may contain butadiene acrylonitrile copolymer and a copolymer of vinyl chloride and vinyl acetate and a solvent comprising acetone and methyl ethyl ketone. Alternatively, a phenolic adhesive may be used. At a heat sealing station, the marginal end portion 24 of the length 25 is lapped over the adhesive-coated skived portion of the length 15 so that the elements 12 of each length extend in the same direction. Heated elements 26, 26<SP>1</SP> are brought together under pressure to form a seam 27. The lengths 15, 25 may both be provided with some hooking elements 12, i.e. hooks (as shown) or loops, or one length may be provided with hooks and the other with loops, e.g. to form a strap, Fig. 8 (not shown). Alternatively, a length provided with hooking elements may be joined to a length of other sheet material.

Abstract: 1444858 Permanent magnets; magnetization C I KASEI CO Ltd 20 Nov 1974 [3 Dec 1973] 50395/74 Heading H1P In fabrication of a film permanent magnet a flexible base strip, e.g. paper, cloth, plastics or metal film is fed from a roll 2 over guide rolls 3, 4 and a rubber backing roll 5 associated with doctor knives 10, 11 to a take up roll 8 over guide rolls 6, 7. A mixture 9 of polymeric organic binder, solvent, and a powdered hard magnetic substance, e.g. barium ferrite in proportion of 80-90% W/W is fed to roll 5, and coated on the base by the doctor knives which are uniformly spaced from the base. The film is thereafter passed through the field of magnetizing means 13 to produce permanent magnetization perpendicualr to the base, and is dried at 14. It is then hot calendered between metal roll 15a and rubber roll 15b, and after cooling wound on roll 8. The film thickness is determined by the spacings of the doctor knives from the film (Fig. 2, not shown) which co-operate with accumulated banks of coating material to remove entrained bubbles. Further doctor knives may be provided in series. The rear surface of the film may be directly printed or coloured. In a modification (Fig. 3, the base film is tensioned and translated by rolls 20, 21 between which it is supported by plates 22, 23, and doctor knives 24, 25 normal to the film are positioned between plate 23 and roll 21 and between 22, 23 to bow the base film downwardly during coating, and to remove bubbles between accumulated banks 26, 27 of coated material.

When the input signal U exceeds the lower threshold T1 switches from off to on, T2, T3, T4 switch from on to off so as to switch the output SA from '0' to '1' and T5 remains off. When the input signal exceeds the upper threshold T5 turns on as do T3, T4 and the output SA is switched to '0' again. In a known circuit Fig. 1, (not shown) when the input U exceeds the lower level the output of a first transistor differential amplifier (T1, T2) is switched and when the input U exceeds the upper level the output of a second transistor differential amplifier (T5, T6) is switch. The outputs of the differential amplifiers (T1, T2 and T5, T7) feed an output SA via an Exclusive OR gate SA so that a '1' output at SA is obtained provided the input signal U is between the lower and upper limits.
