Title: Polyester based coating compositions
IPC: C08L67/06
Filed: 1962-12-21
Abstract: Aqueous coating compositions are produced by treating a polyol having at least 3 hydroxy-groups and a molecular weight of at least 500 successively with (a) a drying oil fatty acid and (b) a maleinized fatty acid and partially or completely neutralizing the product with a base.  Polyols specified include:  a copolymer of styrene and allyl alcohol, and epoxy-resins, e.g. an epochlorohydrin/bisphenol A adduct.  Drying oil fatty acids specified include those of linseed oil, soya bean oil, dehydrated castor oil and tall oil.  2 moles per mole of polyol may be used at 350-450 DEG  F.  Maleinized fatty acids specified include maleinized tall oil, and linseed oil.  This treatment may be at 200-260 DEG  F. for a sufficient time that half the maleic acid carboxyl groups are reacted.  The neutralization may be at room temperature.  Bases specified are ammonia, triethylamine, diethanolamine and diethylethanolamine. The base may be added in aqueous solution or dispersion which may contain an organic solvent, e.g. ethylene glycol monobutyl ether.  The product may be diluted to a coating composition with water or organic solvents, e.g. hexanol, octanol, hexamethylene glycol and ethylene glycol monobutyl ether. The coating composition may also contain a drier, e.g. cobalt naphthenate in ethanol, and a filler or pigment, e.g. Fe2O3, rutile TiO2, barytes, carbon black or fibrous talc.  It may be converted to a baking enamel by adding 5-100% of an aminoplast resin, e.g. a melamine-form-aldehyde resin and 0.01-2% of a catalyst therefore.  In examples, the esterification is carried out in toluene or xylene solution. Potassium tripolyphosphate is used as a dispersing agent. In Example VIII the polyol is an acrylic copolymer of methyl methacrylate, butyl methacrylate, glycidyl methacrylate, thiophenol, and azodi-isobutyronitrile prepared by heating the reactants in isopropanol containing toluol.

Title: Electronic calculator system
IPC: G06F15/02
Filed: 1973-10-18
Abstract: 1447637 Electronic calculators TEXAS INSTRUMENTS Inc 18 Oct 1973 [2 Feb 1973] 48656/73 Heading G4A A programmable electronic calculator has its calculating circuitry 20 (fabricated on a MOS/ LSI chip) driven by clock pulses # i  from driving circuitry 22 (fabricated on a bipolar chip) at one of three different clock frequencies, a first (relatively high) clock frequency being used during a calculating mode of the calculator following a key actuation, a second (intermediate) clock frequency being used during a subsequent displaying mode, and a third (relatively low) clock frequency being used when neither calculating nor displaying is being performed. The clock pulses # i  are produced by a clock generator 126 in driving circuitry 22 which functions so that the relatively high calculating mode frequency is used for typically 0À4 seconds, and the intermediate displaying mode frequency for typically 30 seconds, the display then being disabled and the relatively low frequency used until another key is actuated or until the calculator power supply is de-energized. The calculating circuitry 20 comprises a ROM 100 from which program instructions are sequentially read out into an instruction register 102 by a program counter 120 (unless a branch is indicated by a jump instruction circuit 106), the instructions passing to a decoder 104 and an arithmetic logic unit (ALU) 207. The ALU 207 operates in conjunction with a RAM 110, which is divided into 3 thirteen-digit registers A, B, C (each digit including four bits in BCD format), the contents of RAM 110 being sequentially read out by a commutator 116. Data is entered from a keyboard (12), Fig. 1 (not shown) on lines KN-KQ, and is output in eight-digit form to a display device (13). The display device (13) may comprise digitrons, LEDs, or liquid crystal display units, five of the thirteen digits from registers A, B, C being masked for display purposes by masking circuitry 122. The circuitry of the clock generator 126 and its regulated power supply 128 is given in Fig. 3 (not shown).

Title: Intruder detection device
IPC: G08B13/24
Filed: 1974-11-15
Abstract: 1474928 Intruder alarms SHORROCK DEVELOPMENTS Ltd 8 Jan 1976 [15 Nov 1974] 49433/74 Heading G4N  A receiver for an intruder detection system of the type in which a modulated radio frequency signal is applied to the receiver comprises an aerial RA, a radio frequency detector RFD, signal processing means for providing a D.C. signal the level of which is proportional to the amplitude of the received signal, means for sampling said D.C. signal level at predetermined time intervals, and means for detecting a change in said D.C. signal level, as compared with the level detected in the immediately preceding sample, greater than a predetermined amount, and, in the event of such a change, initiating an alarm. As shown in Fig. 1 the aerial receives an audio frequency modulated microwave signal and the audio frequency modulation is extracted and applied to circuitry comprising a pre-amplifier, a logarithmic amplifier and filter, a rectifier and a low pass filter from which the D.C. signal is obtained. The D.C. signal is applied to an R.C. circuit having a switch arranged between the resistor R and the capacitor C, the switch being turned on for brief intervals of time only by a pulse generator. The D.C. signal is applied via resistor R to one input of a comparator, the other input being coupled to the junction between the switch and the capacitor C. In the static state both inputs to the comparator will be equal. Should any change in D.C. signal level occur, this will immediately be seen by the comparator which may or may not give an output according to the extent of the signal change. If the amplitude change is sufficient to cause a comparator output, this output deenergizes an alarm relay. However, if the amplitude change is insufficient to cause a comparator output, e.g. due to ambient condition changes, on closure of the switch the capacitor C will endeavour to recharge to the altered input signal level. This change reduces the differential input to the comparator and after sufficient pulses from the pulse generator, the input levels to both comparator inputs will equate. As shown in Fig. 2, the D.C. signal is applied to one input of a first comparator and to an R.C. circuit XC1, the junction between X and C1 being connected to one input of a second comparator, the other inputs of both comparators being connected to the output of a voltage follower which follows the charge on a capacitor C2. If the D.C. level change is sufficient, comparator 1 produces an output to de-energize an alarm relay. If the change is small, then the charge of capacitor Cl will alter. When the pulse generator operates to close the switch, the capacitor C2 will attain a state of charge corresponding to that of C1 which in turn, via the voltage follower, will reduce the voltage differential or comparator 1 and change the charge on C1. This sequence repeats until the imbalance is effectively zero.

A method of forming a composite article comprising a layer of PTFE and a fabric layer consists of coagulating a dispersion of PTFE in a liquid carrier to form a thick paste, coating one surface of the fabric with the paste to impregnate a surface layer of the fabric with PTFE particles, drying the coated fabric to remove the liquid carrier, placing the impregnated surface of the fabric in contact with a layer of PTFE and heating to a temperature sufficient to cause coalescence by sintering of the PTFE in the fabric with the layer of PTFE. The layer of PTFE may be a sintered layer or may be formed against the impregnated surface of the fabric by contacting the latter with unsintered PTFE powder or granules and compacting the powder, e.g. by cold-press moulding. The fabric may be woven, non-woven or knitted, may be of asbestos or glass and may be reinforced with metal wires. The PTFE paste may be prepared from a dispersion initially containing 30-70% by weight PTFE and 1-10% of a non-ionic wetting agent. Coagulation may be effected by means of a polar solvent such as acetone. The PTFE layer may contain a filler. The free surface of the fabric in the composite article may be adhesively bonded to some other surface.
