Filed: 1973-12-31
Abstract: 1437141 Metal-working coolants NALCO CHEMICAL CO 31 Dec 1973 [30 April 1973] 60226/73 Heading C5F The capability of metal working coolants comprising a water dispersion to adhere to metal surfaces is improved by the incorporation within the aqueous phase of the coolant of at least 5 p.p.m., based on the total weight of the coolant of a water soluble polymer having a molecular weight of at least 100,000. Lists of suitable polymers and other components of the coolants are given.

Title: Method of making a magnetic disc
IPC: B29C65/48
Filed: 1970-12-23
Abstract: 1348780 Laminated magnetic material FUJI PHOTO FILM CO Ltd 23 Dec 1970 [29 Dec 1969] 61279/70 Heading B5N A magnetic disc is made by preparing a material comprising a magnetic layer applied to a temporary base, applying this material to both surfaces of a base element with the magnetic layers in contact with the latter, and pressing the resulting assembly so that the magnetic layers adhere to the base element. The temporary bases are exposed and can subsequently be removed. The base element or the magnetic layers may be coated with an adhesive before pressing. The whole assembly may be heated during pressing, which may be effected by a pair of convex resilient members. In one embodiment, several discs are made simultaneously by pressing a stack of alternate discs (3) and temporary bases (1) coated on both sides with magnetic layers (2) (Fig. 4). The temporary base may be provided with a projecting tag which facilitates its removal from the magnetic layer. In Examples (1 and 2) pieces cut from a regenerated cellulose sheet coated successively with (a) a magnetic γ-Fe 2 O 3  or CrO 2  nitrile rubber composition and (b) a phenol/polyurethane adhesive are pressed on to both sides of an aluminium disc; (3) polyethylene terephthalate sheets coated successively with (a) a silicone lubricant and (b) a magnetic γ-Fe 2 O 3 /cellulose acetate-butyrate/styrene-butadiene copolymer composition are pressed on to an aluminium disc coated with polyurethane adhesive.

Title: Selectively operable mechanism for keyboard operating machines
IPC: H03M11/02
Filed: 1968-12-31
Abstract: 1,243,640. Keyboards. INTERNATIONAL BUSINESS MACHINES CORP. 31 Dec., 1968 [10 Jan., 1968], No. 61800/68. Heading B6F. Keyboard interlocks.-A keyboard 10 has an interlock member 16 provided with detents 108 which can co-operate with key-stem pins 109, 1091 to selectively lock keys 107, 107<SP>1</SP>. The interlock member 16 is slidably movable to control selectively the operation of the keys. An interposer 33, slidably mounted by pins 34 on the interlock member 16, is moved from its inoperative position to its operative position by depressing key 110. In the depressed operative position, the lower extension 111 of the interposer 33 is engaged by alug 18 of an actuator 20, cyclically movable first in the direction of arrow A and then in the opposite direction. The actuator 20 therefore moves the interposer 33 in the direction of arrow A, which in turn moves the interlock member 16 from its normal position to a selected operating position in which the detents 108 are moved out of alignment with key-stems 109, 109<SP>1</SP>. A spring loaded latch 45 retains the interlock member 16 in the selected operating position. Key 107 is thereafter free to be depressed until such time as key 107<SP>1</SP> is depressed. When key 107<SP>1</SP> is depressed, its keystem pin 109<SP>1</SP> co-operates with a cam 52 on a slider 17 (Fig. 2) thereby moving the slider in the direction of the arrow A. A further cam 50 on the slider 17 co-operates with the latch 45 to release the interlock member 16, which returns to its normal position under the action of spring 27, thereby blocking keys 107 and 107<SP>1</SP>. In an alternative embodiment (Figs. 4 and 5), an additional interposer (88) is provided instead of cam 52, Fig. 1, on slider 17 (75), to provide the movement of the slider in the direction of the arrow A. In this alternative embodiment, this movement is therefore derived from the cyclically moving actuator (105). The latch for the interlock member is released in a similar manner to the previous embodiment by a cam (100). In this alternative embodiment, a detent (121) on the interlock member (74) comes into alignment with a key-stem pin (122) when the interlock member is in its selected operating position and not its normal position.

Title: Locking device for an ignition switch
IPC: H01H27/06
Filed: 1978-06-07
Abstract: An interlock mechanism for an ignition switch has a pawl 23 which is carried by the rotor (not shown) and which can be arcuately moved over the base 14 of a housing 12 between an OFF position and a START position. In the IGNITION position, the base 14 has a recess 15, 16 which can receive the pawl 23 on return from the START position and from which the pawl can be disengaged by movement only up a ramp 17 in the direction away from the START position. An arcuate spring wire 20 overlies the recess 15, 16 and prevents the pawl 23 dropping into the recess when moving from the OFF position to the START position. When in the START position, the pawl 23 engages the free end of the spring wire 20, and, on subsequent return from the START position, causes the spring wire 20 to expose the recess 6 for reception of the pawl 23. <IMAGE>

Patent GB-789150-A (GB)
Abstract: 789,150. Temperature-responsive actuating-elements. ROBERTSHAW - FULTON CONTROLS CO. Feb. 16, 1956 [May 19, 1955], No. 4898/56. Class 64(2) [Also in Group XXIV] A temperature-responsive control-device comprises an element 10 responding to temperature variations indicative of a need for operation of the device and also exposed to variations in another temperature, a control member 38 actuated by the element 10, a first compensating element 24 for modifying actuation of the member 38 by the element 10 in response to variations in the other temperatures, and a second compensating element 50 to modify actuation of the member 38 by the element 10 in response to variations in the other temperature when the latter affects the elements 10 and 24 unequally. The elements 10, 24 and 50 each consist of a bellows, the element 10 being connected by capillary tubing 14 to a temperature sensing bulb 12 and by a bracket 18 to the element 24 which is in turn connected by a bracket 26 and a lever 34 to the member 38. When the elements 10 and 24 are equal in volume, a condition corresponding to only one temperature of the bulb 12, changes in the other, for example ambient, temperature cause equal and opposite movement of the elements so that no movement is transmitted to the member 38. The element 50 also responds to changes in the other temperature and moves a pin 44 in a slot 42 in the lever 34 which is horizontal when the elements 10 and 24 are of equal volume. When the volumes are unequal, the movement of the pin 44 causes rotation of the lever 34 in a direction opposite to that caused by the unequal movements of the elements 10 and 24. In a modified construction, the latter are connected to opposite ends of a lever having a central pivot connected by a link to one end of the lever 34.

Title: An analog measuring installation for the remote display of a measured value
IPC: G08C19/02
Filed: 1980-01-15
Abstract: The invention relates to a two-wire telemetry system for the remote display of a value measured by a sensor 14. The measuring indicator is a galvanometer 16 inserted in series in a first lead connecting a terminal of a source of voltage 10 to the circuit of the sensor. A second return lead 20 connects this circuit to the other terminal of the source. The circuit of the sensor is supplied with power through the galvanometer. The sensor circuit comprises a controlled source of current 22 connected to one of said leads and providing a current which is a function of the quantity measured. The invention has particular application to the measurement of the fuel level in a vehicle. As shown, the sensor is a capacitor Cm which is repeatedly charged and discharged at constant current by sources S1,S2, to derive a sequence of pulses of width varying with capacitance. This sequence is converted 32 to a varying d.c. voltage Um that is used to control the current source 22. The current drawn by voltage regulator 26 and the sensor circuitry can be balanced out by a second current source 28. <IMAGE>
