Title: Absorption refrigerating system
IPC: F25B15/06
Filed: 1962-02-06
Abstract: 975,787. Refrigeration. TRANE CO. Feb. 6, 1962 [Feb. 9, 1961], No. 4511/62. Heading F4H. In an absorption refrigerating system, the flow of heating medium to the generator 14 and the flow of dilute solution from the absorber 18 to the generator are both controlled in response solely to the temperature of chilled fluid leaving the evaporator 16. In the system shown, which employs lithium bromide solution as the absorbent and water as the refrigerant, this temperature is detected by a thermostat 66 connected to pneumatic controller 64 which, via solenoid-operated start-control valve SAV, controls normally open valve 58 in the steam supply line for generator heating coil 56 and normally closed valve 151, or a normally open valve 156, Fig. 3, in the solution circulating system. A strong solution, i.e. one concentrated in absorbent, is recirculated through pump 40 and sprays 44 while a less-concentrated solution is passed through pump 46, conduit 50 and heat exchanger 52 to the generator, concentrated solution being returned to the absorber via conduit 59, the other pass of the heat exchanger and conduits 60, 61. In operation, if the refrigeration load is reduced, the thermostat 66 will cause valve 58 to close to reduce the heat supplied to the generator and valve 151 to open to reduce the rate of flow of solution from the absorber to the generator by allowing some solution to be by-passed direct from conduit 50 to return conduit 60; in the alternative shown in Fig. 3, valve 156 is caused to close so as to restrict the flow of solution to the generator. The system includes also a refrigerant recirculating pump 80, a proportion of refrigerant being used to cool the pumps 40, 46 and 80 through lines such as 88, and a pump 22 for circulating cooling water through coils 20 and 26 in the absorber 18 and condenser 12. The proportion of water flowing through coil 26 is determined by a condenser-temperature-responsive valve 28, and the water is cooled in a tower 32, the proportion of water passing through the tower being determined by a valve 34 controlled by a thermostat 37. If the temperature of the chilled water in line 65 drops below a predetermined value, a pressure switch 73 is actuated to stop the system. The electric control circuit (Fig. 2, not shown) is such that the refrigerant recirculating pump 80 and solution pump 46 continue to operate for a short period; the pump 46 circulates dilute solution to the generator and, via line 98, to the circuit of pump 40, thus flushing out the conduits and preventing solidification when the system cools down. The system includes also a low-temperature cut-out 96 actuated if the temperature in the evaporator should become abnormally low, and a float switch 77, in chamber 76 connected to the evaporator, actuated if the refrigerant level becomes excessively low.

Title: Improvements in and relating to the production of binding agents for foundry moulds and cores
IPC: C11C3/14
Filed: 1960-02-12
Abstract: A setting oil for use in foundry practice (see Group XXII) is obtained by esterifying tall oil and/or tall oil fatty acids and/or fatty acids from semi-drying oils (with or without fatty acids obtained in the refining of drying oils) with a polyhydric alcohol, and thereafter desliming, isomerizing and polymerizing the product. The esterification preferably proceeds at 160-280 DEG C. to an acid number below 15, the polyhydric alcohol used being suitably di- or tri-pentaerythritol, but preferably pentaerythritol itself; the subsequent desliming, isomerization and polymerization are invariably performed simultaneously at 300-330 DEG C. to a viscosity of 150-350 P20o.  The resinic acid content of the final product is adjusted to less than 25% by suitable proportioning of the starting materials, and 5-15% of a conjugated oil such as wood oil may be added to the initial mixture to accelerate the polymerization.  German Specifications 967,027 and 1,039,164 are referred to.

Abstract: 992,175. Automatic Speed and current control. LICENTIA PATENT-VERWALTUNGSG.m.b.H. Feb. 7, 1963, No.5030/63. Heading G3R. [Also in Division H2] A resistor 10 is connected through choke 5 to rectifier 4 associated with a winding of an A.C. motor, a semi-conductor switch 1 being in parallel with the resistor so that the on/off periods of the switch determine the mean current in the winding. Each conducting period of the switch may be terminated by a quenching circuit comprising a further semi-conductor switch controlling the discharge of a capacitor, a choke and a diode being used to recharge the capacitor. In other arrangements, a semi-conductor switch is connected in series with the resistor for controlling the effective external resistance value, or semi-conductor switches may be connected respectively in series and in parallel with the resistor. A capacitor suppresses voltage surges when the series switch becomes non-conductive. A three phase induction motor has its stator winding associated with reversing contactors and its rotor winding with a short-circuiting contactor. A control unit compares a reference voltage with a tachometer voltage and produces signals for controlling semiconductor devices in the rotor circuit. As shown, rectifier 16 is connected to the supply network and applies across the resistor 10 a voltage which opposes the output of rectifier 4, this opposing voltage being controlled by switch 13. Control unit 12 compares a reference signal with a signal derived from current transformer 11 to control the switch 1, whilst unit 20 compares a reference signal with a signal derived from transformer 21 to control the switch 13. The motor may be supplied from an alternator whose excitation is varied from a unit which also controls the rotor current. The motor may be adapted for pole-changing or stardelta control. The control arrangement is also effective during braking periods, when the motor operates as a generator.

Abstract: 511,579. Condensers. LORENZ AKT.- GES., C. Feb. 19, 1938, No. 5260. Convention date, Feb. 19, 1937 [Class 37] [Also in Group XL] The circuit elements of amplifying apparatus, which may comprise condensers, are arranged to have their input and output terminals at opposite ends and are mounted on step-shaped supports perpendicular to the base plate of the apparatus so that the upper part of one element is adjacent to the lower part of the adjoining element. By this means the length of the interconnecting leads is reduced, thereby effecting a reduction of the inductance and capacity introduced by such leads and of the unwanted capacity between the leads. The embodiments described relate to arrangements of valves and Fig. 3 shows a plan view of two valves 2, 3 mounted on supports 11. The Specification as open to inspection under Sect. 91 comprises also modifications in which the step-shaped support is horizontal and parallel to the base plate, Fig. 5 (Cancelled), and in which the support is vertical.
