Title: Magnetic Tape Cartridge
IPC: G11B23/06
Filed: 1968-03-25
Abstract: 1,188,081. Magnetic tape cartridges. STEREODYNE Inc. 25 March, 1968 [10 April, 1967], No. 14167/68. Heading G5R. An endless magnetic tape cartridge includes a hub 50 of inverted truncated conical shape 66 and having an upwardly inclined flange 55 supporting a plate 56 carrying a tape coil 18. As tape tension increases during use, a force F is generated tending to rock the plate about the upper edge of flange 55 thereby transferring the coil weight from ridges 62 to ridge N1 and reducing friction torque. The hub 50 may be rotatable relative to the flange which is itself rotatable on a spindle extending from the cartridge base. This is said to reduce wear. A slack loop formed in the tape due to vibration is guided above the tape coil so as to enter a chamber defined between a second plate 64 atop the coil, and walls (48, 49, Fig. 3, not shown) depending from the cartridge cover.

Abstract: 470,128. Changing frequency. ASSOCIATED ELECTRIC LABORATORIES, Inc. May 19, 1936, No. 14209. Convention date, June 3, 1935. [Class 38 (ii)] Relates to a frequency changer of the type in which A.C. is supplied to a circuit 2, 3, Fig. 1, resonant at a frequency which is a sub harmonic of the supply frequency, the output being taken from across one of the elements 2, 3 and consists in including in the circuit a source of D.C. to effect starting. Oscillation at the lower frequency, in the form shown in Fig. 1, is commenced by opening a circuit connected across the choke 2 consisting of a D.C. source 5 and a switch 4. In a modification the switch and D.C. source are connected across a secondary winding associated with the choke 2. In a further modification, the D.C. source is formed by a rectifier e.g. as shown in Fig. 3 in which a rectifier 15, is connected across part of the choke 2 through a switch 4 having operating windings 12 to give automatic breaking of the circuit after the main circuit has been established. A condenser 11 and choke 10 is provided to reduce radio frequency disturbance'and a fuse or thermal cut-out 16 to open circuit in event of faulty operation. To give stability of operation at varying loads the condenser 3 may have connected in parallel with it a choke which operates on the knee of the magnetization curve. Further this choke may be designed to resonate with the condenser 3 at the same or a harmonic of the frequency at which the circuit 2, 3 resonates. In a modification of this the choke is replaced by a transformer 8, Fig. 3, by means of which the condenser 3 is connected in circuit. The load circuit 6 may be connected to a secondary of this transformer and adjustment of the higher harmonics effected by means of an auxiliary adjustable choke 18 in series with the condenser. U.S.A. Specification 1,633,481 and various periodicals are referred to.

Title: Process for fixing aminoplasts in the wet state on fibrous materials
IPC: D06M15/423
Filed: 1957-05-07
Abstract: Aminoplasts are fixed at a raised temperature in the wet state on fibrous materials by means of a catalyst which is a partial ester of glycerine with a monobasic acid, an ester of a glycol or glycol monoether with a monobasic acid, or an ester of a polybasic acid with a monohydric alcohol.  Suitable catalysts are diacetin, monochlorhydrin, dichlorhydrin, glycol diacetate, glycol methyl ether acetate, glycol ethyl ether acetate and diethyl tartrate.  The term aminoplast is used to include formal-dehyde condensates with such substances as urea, thiourea, cyanamide, dicyandiamide, biguanide, melamine, formoguanamine, acetoguanamine or alkyl or acyl derivatives thereof.  The condensates may be etherified. They are used as aqueous colloidal solutions or dispersions which may or may not yield precipitates on dilution with water.  The bath preferably contains 5-15% of aminoplast and 5-10% of the weight of aminoplast of catalyst and has a slightly alkaline pH, which during storage should be kept, by addition of alkali, above 7,2.ALSO:Aminoplasts are fixed at a raised temperature in the wet state on fibrous materials by means of a catalyst which is a partial ester of glycerine with a monobasic acid, an ester of a glycol or glycol monoether with a monobasic acid or an ester of a polybasic acid with a monohydric alcohol.

Excess treating liquor is preferably removed mechanically from the treated fibrous material, e.g. loose fibres, yarns, fabrics or knitted goods, which is then maintained at raised temperature e.g. in a closed vessel heated with direct steam to prevent premature drying. In Example 1, hanks of cotton yarn were impregnated with an aqueous solution of melamine-formaldehyde condensate containing dichlorhydrin and centrifuged.  One hank was dried and heated and the others heated in a closed vessel while wound round strips of wet material-one at 80 DEG C. for some hours and the other at 130 DEG C. for one hour.  The degree of fixation of the resin is compared.  Example 2 describes a similar rot-proofing treatment of cotton yarn using diacetin as the catalyst.

Title: Valve unit for braking pressure control in wheeled vehicles
IPC: B60T8/36
Filed: 1975-04-10
Abstract: 1497150 Brake control valves SAABSCANIA AB 10 April 1975 [22 April 1974] 14828/75 Headings F2F and F2V A pneumatic brake has a valve with an inlet 1, a connection 4 to the brake cylinder, and an exhaust 2. An inlet valve comprises a diaphragm 14 exposed on its underside to inlet pressure in chamber 29 and brake pressure in the connection 4, so that the force lifting the diaphragm increases with brake pressure. The upper side of the diaphragm is exposed either to inlet pressure, via passage 27, or to exhaust, via passages 31, 32, 33, 34 depending on the position of the solenoid valve 6. The ratio of the diaphragm area exposed respectively to inlet and brake cylinder pressure is however such that when repeated electrical pulses of constant length are applied to close the solenoid valve 6, the pressure in the brake connection 4 increases by a constant amount each time. Preferably less than a third of the diaphragm area is exposed to inlet pressure. That is, the increasing valve opening period due to increased brake pressure on the diaphragm, compensates for the slower flow of air due to the reducing differential between the inlet and brake pressure. An outlet valve operated by a solenoid 7 may operate to vent the brake cylinder, via a diaphragm 15 which may be integral with the diaphragm 14.

Abstract: 1,093,316. Sawtooth generators. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 4, 1966 [April 7, 1965; July 9, 1965], No. 14854/66. Heading H3T. [Also in Division G3] The voltage from a source 14 (e.g. a pulse generator) applied to a temperature-dependent load 13 (e.g. an inductance producing a sawtooth current) is maintained constant by controlling a series transistor 2 in dependence upon load voltage variations as detected by a bridge network constituted by resistors 15, 16, 17 and a circuit 8 arranged to compensate for temperature changes. The circuit 8 comprises a transistor associated as shown with a voltage divider 10, 11 and the emitter/collector voltage of the transistor serves as the reference voltage for the bridge network, the output from which is applied, over an amplifying transistor 18, as a control signal to the base of transistor 2. The bridge network may include a resistor 19, carrying the load current, to compensate for load fluctuations. The current can also vary because of temperature changes in the transistor 2 and the load 13, resulting in an incorrect control action. The Specification explains how the values of the resistors 10, 11 are related to the base/emitter input impedance and the base/ emitter threshold voltage of the transistor 9 in order to compensate for the temperaturedependent variations in the load current. The resistor 10 may itself be in the form of a voltage divider having its tapping connected over a resistor (21) to the supply voltage (Fig. 3, not shown) so that the base/emitter voltage of transistor 9 may be adjusted independently of the values of resistors 10 and 11. The pulses may be applied to the base of the transistor 2.
