Abstract: 920,218. Determining specific gravity. A. BALLESTIA. Sept. 29, 1959 [Oct. 11, 1958], No. 32997/59. Class 97 (3). [Also in Group XXXVI] A method of simultaneously indicating the specific gravity and the humidity of sprayed powdered substances, particularly detergents, comprises passing the powdered substance through a receptacle so connected to a pivoted lever that a pointer on the lever continuously indicates on a scale the specific gravity of the substance passing through the receptacle and at the same time indicates the humidity by an electrical device. The apparatus for carrying out the method comprises a receptacle 3 through which the material flows from a slide 1. The receptacle pivots on the branched end of a lever 8 which has a fulcrum support 9 and a sliding counterweight 11 or screw-tensioned spring which is initially adjusted to give a predetermined reading of an indicator B on a scale 14. Alternatively a pen may move over a cylinder of paper to continuously record the specific gravity. The humidity of the material is determined by the readings of a valve voltmeter 26 in circuit with a high-frequency oscillator 25 and two plates 24 spaced apart in the material in the receptacle. One plate is connected to earth. A voltage-stabilizing valve is in circuit with the valve voltmeter.

Title: Improvements in electrical systems for amplifying weak electrical signals
Inventor: YOUNG GEORGE VIRGIL
IPC: H03F3/387
Filed: 1961-09-20
Abstract: 949,334. Automatic vibration amplitude control. ENDEVCO CORPORATION. Sept. 20, 1961, No. 33703/61. Heading G3R. [Also in Divisions H3 and H4] The invention relates to an amplifier of the chopper type (see Divisions H3 and H4), i.e. in which low frequency and D.C. signals are converted by a chopper device to envelope modulated high frequency waves which amplified and demodulated, the chopper device comprising a vacuum-enclosed vibratory capacitor. Constructional details of the vibratory capacitor are described in the Specification, and are as described in Specification 949, 335 (see the latter, in Division H1). It is driven by means of a solenoid 34. An oscillator 13 is provided of higher frequency than the vibratory capacitor and of high amplitude stability, feeding into a potentiometer comprising resistor 93 and transformer secondary winding 90. Due to the variable impedance reflected from the capacitor 26, the voltage at the tapping point 91 of this potentiometer comprises oscillations from the oscillator 13 amplitude modulated by the capacitor 26. This voltage is amplified in amplifier 12, the output of which comprises two parts. The first part is passed by resistor 119 and capacitor 120 to variable gain amplifier 117, which is followed by fixed gain amplifier 125, the output of which is fed to the solenoid 34 and drives the vibratory capacitor. The solenoid 34 is resonated by means of series capacitor 129. The second part of the output of amplifier 12 is passed by transformer 95 to rectifier 96, the output of which comprises oscillations at chopper frequency. After filtering by network 99, 100, 101 this is compared in transistor 105 with a constant voltage derived from a Zener diode 111; the output from the collector, after smoothing by filter network 78 consists of a D.C. voltage proportional to the difference between the Zener voltage and the chopper voltage. This is applied to the base of transistor 115 so as to vary the gain in such a sense as to stabilize the amplitude of vibration of the vibratory capacitor 26.

Title: Improvements in or relating to a hot water accumulator plant
IPC: F01K1/04
Filed: 1946-11-13
Abstract: 631,964. Heating by circulation of fluids. RUTHSACCUMULATOR AKTIESELSKAP. Nov. 13, 1946, No. 33760. Convention date, Nov. 17. 1945. [Class 64(ii)] Relates to a hot water accumulator plant, in which two circulation systems are connected to the accumulator 3, one of which includes a hot water consumer 12 and starts from the upper part of the accumulator 3 below the water level and returns at the bottom, while the other (the loading circuit) starts from a point near the bottom of the accumulator 3 and returns above the highest water level to condense, in a contact condenser, steam from a supply line 2 which discharges in this region of the accumulator. According to the invention an automatically controlled valve 4 in the steam supply line 2 and another 16 in the loading circuit are adapted to keep constant the steam pressure and upper layer water temperature in the accumulator. Steam is supplied from a boiler 1 fed from a reservoir 8 into which surplus water from the loading circuit is discharged under the control of a valve 9 influenced by a float in the accumulator 3. The valve 16 in the loading circuit allows more water to flow to the top of the accumulator 3 when the pressure in the steam supply line 2 increases (e.g.. when the steam demand of other plant 5 in the boiler circuit decrease) and therefore the valve 4 in the supply line 2, responding to the pressure decrease in the accumulator, allows through more steam to maintain the pressure and temperature in the accumulator 3. A drop in the pressure in line 2 tends to close valve 16 and if big enough may cut off the water circulation to the top of accumulator until pressure builds up again. A cold water supply line 18 connects to the bottom of the accumulator and an automatic or hand valve 15 controls a byepass in the hot water consumer circuit. Thermo-couples 17 are distributed at various levels in the water in the accumulator and connected in series to give an average water temperature reading. Instead of being controlled by pressure the valves 4, 16 may be temperature responsive. In a modification (not shown) the steam supply valve 4 is controlled by the pressure in the supply line 2 and the valve 16 by the pressure in the accumulator 3.
