Title: System for reading, recording and resetting registered data
IPC: H03K21/08
Filed: 1965-08-23
Abstract: 1,120,791. Counting apparatus. WELTRONIC CO. 23 Aug., 1965 [21 Aug., 1964], No. 36117/65. Heading G4D. In apparatus for reading and resetting a digit register, e.g. a decimal counting wheel, the register is stepped through a complete cycle while the number of steps required to take the register from its initial count to a reference count, e.g. 9, are determined, this number being translated into the initial count, and the register is then stepped by the number of steps required to take it from the initial count to a datum count, e.g. zero. As described, the digit registers are denominations of accumulators 26-29, Fig. 1, used respectively to register units produced, pieces produced, production time and down time at a work station of a production monitoring system in a factory. Each digit register has a pulse-stepped solenoid drive, and, as shown in Fig. 2, reading of the registers is accomplished by pulsing each register simultaneously by means of pulse generator 196. The pulses from the generator drive a counter 198 which through sequencing circuits 51 controls a pulse gate 52. When a read-transfer signal is issued to the system, the pulse generator applies its first 10 pulses through gate 52 to advance each register; thereafter gate 52 prevents the transmission of additional pulses. When the reference digit 9 is reached a contact is closed as at (UU) (Fig. 10, not shown). A memory 53 comprising 4 relays is provided for each register, said memory being enabled to convert the count to a binary code and when the ninth position contact for the corresponding register is closed the coded count is held. The memory relays establish a visual readout of the count through a contact matrix (Fig. 14, not shown) as at indicator 54 and also set up circuits which operate card punches for a recorder device 55. The memory relays also close reset leads to apply enabling pulses to amplifiers connected to the register driving solenoids, i.e. the amplifiers constitute reset drivers 56. Thereafter the pulse generator is recycled to cause it to generate 16 pulses for resetting the registers. The pulses are applied through counter 198 which transmits them through coder 57 having four output leads. The reset pulse train is issued from the coder as 1, 2, 4 and 8 pulses on each individual lead so that all combinations of from one to ten can be obtained at the reset driver 56. Each register solenoid is then subjected to the number of pulses required to return it to its zero position. Verification of the reset is obtained by a contact on the registers which is opened only at the zero position in a parallel circuit to actuate an interlock circuit in the event that one of the registers was not reset to zero. Verification of the register reset enables the reset of the memory by releasing all relays.

Title: A process of preparing improved wetting agents and detergents, and products thereof
IPC: C07C303/00
Filed: 1934-12-20
Abstract: Paraffin wax or petrolatum is cracked so as to produce a product containing olefines having more than six carbon atoms in the molecule, the latter is treated with excess of a strong sulphating agent at a temperature below about 50 DEG  F., and the excess acid is removed or the free acid is reduced to below about 60 per cent concentration without permitting a rise in temperature.  This may be done by diluting or neutralizing with adequate cooling or by extraction of acid or sulphated products by means of solvents.  The products are stated to have wetting and detergent properties. Cooling may be effected by direct or indirect heat-exchange, using liquid refrigerants such as propane, butane, pentane, liquid sulphur dioxide.  For mixing the reagents, turbomixers, opposed jets, baffles, &c. may be employed.  In examples, cracked petrolatum or paraffin wax is treated with oleum with cooling and vigorous agitation and is neutralized with caustic soda while maintaining the temperature below 20 DEG  F.  The product is worked up by means of isopropyl alcohol to separate inorganic salts and unattached oils, and is dried after addition of slight excess of ammonia.  The treatment of the cracked wax or petrolatum may be effected in the presence of other reactive compounds such as fats, fatty acids, alcohols, oxidized petroleums and paraffin wax, coal tar distillates, ethers, esters, aldehydes, ketones, phenols, naphthenic acids, polymerized animal and vegetable oils, resins, terpenes, amines, sulphur compounds, chlorinated wax, naphthalene, diphenyl, and diphenyloxide.

Abstract: 1,120,286. Battery charging systems. J. STONE & CO. (DEPTFORD) Ltd. 16 Aug., 1966 [2 June, 1965; 18 Aug., 1965], Nos. 36548/66 and 35432/65. Heading H2H. [Also in Division G3] A battery charging installation comprises an alternator 1 supplying both a battery 2 and a load 3 over a rectifier 4a, the alternator having a field regulator 4b, e.g. of the saturable reactor or transistor type, which receives by way of a transformer 12 one control voltage dependent upon the output current of the alternator and another control voltage derived from a resistor 8 forming part of a voltage divider 8, 9, 10, 11 connected across the output of the rectifier 4a. A transistor 14 has its collector/emitter path connected across resistor 11 and its base connected over a resistor 15 to the junction between the battery 2 and a resistor 6 connected in series therewith. The regulator 4b controls alternator 1 to limit the voltage to the maximum suitable for the battery and to limit the current to the rated full load value for the alternator, but the voltage control is modified by the action of the transistor 14 so that the voltage/ current characteristic of the charging current which reaches the battery is caused to droop with increase of said current. Thus, as the charging current through resistor 6 increases, the base of transistor 14 becomes more negative and the transistor 14 becomes more conducting thereby reducing the effect of resistor 11 and thus reducing the voltage setting of the regulator 4b. It is stated that this arrangement, by reducing the charging current as the battery approaches a fully charged state, reduces the risk of " thermal runaway " in low resistance batteries such as those of the nickel/cadmium type. The arrangement may incorporate a further transistor having its collector/emitter path connected across the resistors 9, 10, 11 (Fig. 3, not shown), and may be applied to a D.C. generator with a carbon pile regulator. In one embodiment (Fig. 1, not shown), the required drooping characteristic is obtained by connecting a resistor, shunted by a diode, in series with the battery, the diode being poled so that it is non-conductive to the charging current but conductive to current passing from the battery to the load 3.

Abstract: 1479037 Integration circuits PHILIPS BROADCAST EQUIPMENT CORP 21 Aug 1974 [24 Aug 1973] 36769/74 Heading G4G [Also in Division H3] An integrating circuit comprises an amplifier 10 having an inverting input 12 connected to a source 18 of input voltage to be integrated and to a source 28 of keying pulses, a clamping diode 24 and compensating diode 26 being connected between the output of the amplifier and the inverting input. When the keying pulses are absent during time period 50-52, diodes 24, 26 are non-conducting and an input voltage of e.g. - 12 volts from source 18 is integrated upon capacitor 22 (curve b). When a pulse of + 12 volts is applied during period 52-53, it forward-biases the diode 26 and is therefore applied to input 12 and quickly discharges the capacitor during period 52-54. At time-point 52, the diode 24 starts conducting and clamps the output voltage to zero. The diode 26 has similar characteristics to the diode 24 and compensates the voltage drop across the latter. The operation of a second integrating circuit 32, 44 with clamping diode 46 produces a parabolic output voltage (curve c). A variable voltage, determined by the setting of variable resistance 38, is applied to the inverting terminal of the second amplifier 32 and determines the shape of the curve c.
