Title: Control system for frying apparatus
IPC: B08B7/00
Filed: 1975-03-07
Abstract: 1515364 Control system for frying apparatus FRYMASTER CORP 7 March 1975 [17 June 1974] 96081/75 Headings F4W and F4X [Also in Divisions H2 and H5] An apparatus for frying foods comprises heating elements 22, Figs. 1 and 6, a thermostat 66, Fig. 6, for maintaining the temperature of the heating elements below a first limit during a cooking phase with the elements immersed in a cooking fluid and another thermostat 70 for maintaining the temperature of the heating elements below a second limit during a pyrolytic cleaning phase with the heating elements exposed to the atmosphere. As shown in Fig. 1, the heating elements 22 are in a cooking basin 16. The heating elements are attached to a pivot piece 38 so as to be pivotable out of the basin for pyrolytic cleaning. The pivoting is effected by an arm 40. A thermostat 50 keeps the temperature of the fluid as set by a selector dial 52. Should this thermostat fail, the thermostat 66, Fig. 6, operates so as to maintain the temperature below the first limit. If this thermostat 66 should fail the thermostat 70 operates at a higher temperature. When the heating elements 22 are pivoted out of the basin for pyrolytic cleaning a switch 98 automatically operates so as to remove control by thermostats 50 and 66, so that the only effective control is then by thermostat 70. Both of the thermostats 66 and 70 are secured adjacent to the heating elements 22 (Fig. 4 and 5, not shown). Details of the circuitry.-Power is connected to the heating elements 22 via contacts 84a, 84b, 84c, Fig. 6, and 86a, 86b, 86c. All contacts 84 are controlled by a coil 88. All contacts 86 are controlled by a coil 90. Depression of switch 96 energizes coil 88 and so closes contacts 84. On-off switch 56 is provided. Movement of the heating elements from a cooking to a pyrolytic cleaning position automatically moves the switch 98 from position 102 to position 100. In each position the switch 98 makes a connection which allows energization of the coil 90 and thus closure of contacts 86. With switch 98 in position 100 for cooking, the operative thermostat is 50 which opens contact at a lower temperature than, and is backed up in turn by, thermostats 66 and 70. Opening of thermostat contact 50 or 66 de-energizes coil 90 and opens contacts 86 in the power supply to the heating elements 22, whereas opening of thermostat contact 70 de-energizes coil 88 and opens contacts 84. With the switch 98 in position 110 for pyrolytic cleaning, the thermostats 50 and 66 are by-passed and the operative thermostat is 70. Thermal percentage relay switch 106 cycles between positions 108 and 110 so energizing and de-energizing coil 90 and opening and closing contacts 86. By this means the power supply to the heating elements 22 is cyclically switched on and off and their temperature builds up gradually until thermostat 70 opens contact. Thereafter, further power cannot be supplied to the heating elements 22 until after switch 96 has been depressed again. Specification 1,515,365 (in Abridgement Divisions G3 and H2) is referred to.

Title: Improvements in and relating to coin-operated ticket machines
IPC: G07F17/42
Filed: 1941-07-29
Abstract: 549,064. Coin-freed ticket machines. WESTING-HOUSE BRAKE & SIGNAL. CO., Ltd., and McLEAN, D. M. July 29, 1941, No. 9613. [Class 27] Coin-freed machines for printing and issuing tickets which may be of different kinds are arranged to be readily changed from one kind of ticket to the other by an official either manually at the machine itself or by remote control. For two kinds of ticket two separate printing and issuing units 1 and 2 are used the actuating levers 3 and 4 of which can be operated by electromagnets 5 and 6 respectively. The circuit shown in Fig. 2 issues tickets under control of a coin operated-switch 8 from one or other magnet 5, 6 alternatively as selected by a throwover switch 7. To prevent change over during operation of a machine, and therefore issue from both machines for one coin insertion, the circuit shown in Fig. 3 is used, where the throw-over switch 7 is operated by a magnet 9 controlled by its switch 10 and controlling the selection switch 11. A switch 18 operates an indicator 15 or 16 and a switch 12 prevents failure if the switch 10 is opened or closed during operation. The selection of kind of ticket may also be done mechanically by axially displacing by a knob 24, Fig. 4, a coupling plate 20 and its carrying spindle 22 so that the coin operated lever 19 may depress the plate against the lever 3 or 4 selector. A spring catch 25 retains the coupling plate in either position.

Abstract: 856,550. Character recognition devices. NATIONAL CASH REGISTER CO. March 20, 1959 [April 14, 1958], No. 9683/59. Class 106 (1). As described, characters, each having a distinctive width, are sensed by a single broad magnetic, Fig. 1, or photo-electric (not shown) scan, to produce signals which after being shaped and clipped should appear as shown in Fig. 4. These signals are distributed, by the first ten pulses, from a transistor oscillator 26, which is started by the first pulse sensed from the character, to a register 20 of ten cores. The eleventh pulse from the oscillator transfers the stored data from the register 20 to a ten-core recoding register 29 which is so arranged that the only core that is set " on corresponds to the last pulse produced by the sensing of the character. The twelth pulse from the oscillator resets the recoding register producing an output on a single line which is passed to an indicating unit 37 of which no details are given and completes a recognition cycle.

Title: Process for removing hydrogen fluoride from mixtures comprising aromatic ketones
Inventor: CURTIS THOMAS ARNOLD
IPC: C07C45/85
Filed: 1990-11-15
Abstract: A method is provided for separating hydrogen fluoride (HF) from a mixture comprising HF complexed with an aromatic ketone in which the keto carbon atom is directly bonded to an aromatic ring carbon atom, e.g., 4-isobutylacetophenone, by adding a carboxylic acid anhydride, e.g., acetic anhydride, to the mixture while maintaining the mixture at conditions sufficient to sustain a reaction between the anhydride and the HF to form the corresponding acyl fluoride, e.g., acetyl fluoride, and carboxylic acid, e.g., acetic acid, and separating the acyl fluoride from the mixture. The method is conveniently carried out in a stripping column near the top of which the mixture comprising aromatic ketone and HF is fed and below which the anhydride is fed. Between these feed points, the uncomplexed HF is stripped from the mixture, while below the anhydride feed point or points, the anhydride reacts with the complexed HF to form the acyl fluoride which is stripped from the mixture, and the carboxylic acid. The separation method may be integrated with the production of the aromatic ketone by the Friedel-Crafts acylation of an aromatic compound, e.g., isobutylbenzene with an acyl fluoride, a carboxylic acid anhydride, a free carboxylic acid, or a mixture of the foregoing reactants, using an excess of HF as catalyst, to produce the mixture comprising aromatic ketone and HF to be separated, and to which the separated HF and in some cases the acyl fluoride may be recycled.

Title: Three phase transformer
Inventor: INAGAKI KEISHIN
IPC: H01F30/12
Filed: 1980-01-11
Abstract: PURPOSE:To prevent the overcurrent by setting a primary and a secondary main and auxiliary windings at a leg of a three phase iron core and connecting the auxiliary winding of other phase to the main winding in series, thereby fixing an impedance between the primary and the secondary windings at a given relation. CONSTITUTION:A three phase transformer 92 is provided in parallel with an established transformer 91 which is operating connecting an A and B system, and a circuit breaker 93 is provided. When the impedance between the primary and the secondary windings of the established transformer 91 is Xr, the current, I=(XT/ XT+X)IA flows to the transformer 92, in case of an accident. Accordingly, according to The venin's theorem, if VO is a potential difference between the points a and b before the establishment of the high voltage transformer 92, and XO is an impedance of the power system between the points a and b when the whole power source of the power system is removed at the time of an accident before the establishment, the current, I=VO(VO/XO+X) flows to the transformer in case of the accident. Accordingly, by forming X>=VO/I-XO of impedance, a small sized and economical transformer can be obtained at ordinary time withholding the overcurrent at a given high impedance at the time of accident.

Title: Examination of furnace for damage
Inventor: FUNAKI MICHIHIRO
IPC: F27D21/00
Filed: 1995-01-09
Abstract: PURPOSE: To enable accurately locating a damaged spot in a furnace without suspending its operation for a long time by a method wherein an atmospheric gas is introduced into the furnace at a constant temperature and the relation of the differential pressure between the pressure inside the furnace and the atmospheric pressure to the height in the furnace as determined for varied flow rates of the atmospheric gas is examined in a manner of determining the height in the furnace. CONSTITUTION: An electrical heating furnace 1 is heated by an electric heater 4 while nitrogen gas of high purity is blown into the furnace through a nitrogen gas inlet 5 and, to prevent oxidation of steel material 3, the oxygen concentration is put under control to be kept, for example, below 1,000ppm. Next the furnace pressure is checked, for example, at positions P, Q, and R in the furnace 1 at heights of 1.2m, 2.2m, and 3m respectively. The furnace pressure at the positions P to R is checked while the flow rate of the nitrogen gas introduced from the inlet 5 is increased or decreased. When damage occurs in the shell at a spot with the furnace pressure at a positive value relative to the atmospheric pressure, the furnace pressure at that spot falls with leakage of the atmospheric gas so that the damaged spot in the shell can be located.
