Abstract: 1,160,348. Washing machines. DANFOSS A/S. 16 Oct., 1967 [17 Oct., 1966], No. 47069/67. Heading D1A. A programme-controlled washing machine has an electronic counter whose outputs each correspond to a programme stage and which progresses from one stage to the next when a pulse is fed to its input. Electronic counter Z comprises five bistable circuits 1, 2, 3, 4, 5 and one two-stage decoder which, in the first stage has two diode matrices 6, 7 and in the second stage diode matrix 8. When pulses are applied to the input 10 of counter Z, voltages are produced at successive outputs 1-32. The washing machine has ten control circuits S1-S10 supervising temperatures liquid levels, timer prewash, wetting, main wash, rinse and spin and seven working circuits for water and washing powder supply, draining pump, washing motor, spin motor and heater. Run-dry and overflow protection circuits may also be provided. Each circuit S1-S10 transmits a pulse to counter Z on completion of the stage controlled by it. The outputs of counter Z and inputs of the circuits S and A are connected by interchangeable bay plate 13 to select the required programme and a fixed switch box 14 in which all the programme stages are wired, e.g. as shown for the first stage. By-pass leads 16 connect a given counter output through lead 17 to counter input 10 if the stage is not required so that the pulse switches the counter to the next output and any number of stages can be skipped very rapidly.

Abstract: 1292113 Keyboards for printers R G MALING 2 Oct 1969 [4 Oct 1968] 47270/68 Heading G4H [Also in Division B6] A keyboard has keys which are operated by movement of the digits of one or alternatively both hands without requiring movement of the hand or hands as a whole and which generate electric signals which are stored temporarily prior to decoding and operating a unit such as a typewriter, typesetting machine or computer. The keys can be operated by up and down or sideways movement of the fingers which enables high speed key operation so that the unit can be operated at its maximum speed. The store avoids a discontinuous key selection if the machine has a discontinuous action. Single keys, or combinations or permutations of successive keys may represent single characters, words or phrases, or control functions of the unit. The store translates the key signals into control signals for the unit. In Fig. 1 three types of key and contact actuation are shown with keys above and below each finger. Fingers 1 and 15 operate mechanically single and double contacts respectively and finger 5 operates relay contacts 10, 11 via proximity switches 6, 7.

Title: Method of improving high temperature characteristics of silica fibers
IPC: C03C25/38
Filed: 1964-11-24
Abstract: Silica fibres are treated to improve their high temperature stability by contacting all the exposed surface of the fibres with an organic chromium salt, bonding the salt to the surface and thereafter heat decomposing the salt on the fibres by oxidative heat decomposition to chromium sesquioxide which adheres as a bonded layer enclosing the silica fibres. The fibres may contain at least 96% silica and may be treated in bulk, felt, mat or woven textile form.  The organic chromium salt may be chromic acetate, chromic formate or chromium naphthenate.  The salt may be dissolved or dispersed in a medium, e.g. water and the contacting may be carried out by spraying or painting the fibre with the salt or by immersing in a bath of the salt, the silica fibres being maintained in the salt until saturated. After the contacting step, the medium is removed by draining and drying the coated fibres at, near or above the boiling-point of the medium causing the coating to be bonded firmly to the surface of the fibre.  The dried, coated fibres are then heat treated in a free oxygen-containing atmosphere at a temperature sufficient to decompose the organic chromium salt in the case of chromium acetate or formate to chromic carbide and to convert the chromic carbide in situ to chromium sesquioxide, e.g. 1600 DEG  to 2000 DEG  F. The concentration of chromium sesquioxide may be between 0.5 and 20% calculated as chromium.  The process may be repeated several times, and may be carried out on a batch, semi-continuous or continuous basis.  The treated fibres show increased resistance at 2400 DEG  to 2600 DEG  F. to degradation of flexibility, softness, breaking strength, and decreased thermal conductivity.ALSO:Silica fibres in bulk, felt, mat or woven textile form are treated to improve their high temperature stability by contacting all of the exposed surfaces of the silica fibres with an organic chromium salt, bonding the salt to the fibres and thereafter decomposing the salt by oxidative heat decomposition to chromium sesquioxide which adheres as a bonded layer enclosing the silica fibres.  The chromium salt may be chromic acetate, formate and chromium naphthenate, dissolved or dispersed in say water, and the solution or dispersion applied by dipping, spraying or painting.  The process may be repeated several times and may be carried out on a batch, semi-continuous or continuous basis.
