Abstract: 429,599. Towel rollers. ROTTENBURG, H., 5, Adams Road, Cambridge. Nov. 30, 1933, No. 33542. [Class 52 (v)] A heated spring towel-roller comprises a hollow roller A<2> mounted on a fixed shaft A<1>, B supported by brackets C<1>, C<2> and containing a fixed heater K and a spring D, the towel being clipped or clamped at one edge to the roller and wrapped round it so that on unrolling the towel the spring is tensioned and will re-wind the towel when released. The heater K is supplied with electricity or hot water through the brackets C<1>, C<2>. The closed end C<4> of the roller has a ratchet wheel P engaged by a pawl Q to retain the roller when the towel is being used ; this pawl is rocked by a knob T<1> to release the roller for re-winding, the other side of the pawl then contacting with an annular rim U to act as a brake. To limit the rotation of the roller in either direction inwardly projecting pins I, J near the open end of the roller engage longitudinal grooves in a circular member H threaded on a screwed part B of the fixed shaft A<1>. As the roller rotates the member H is moved along the screwed shaft and contacts with either of two fixed stops L<1>, L<2> to limit the rotation. The spring D is anchored between a boss E on the roller and a boss F on a fixed disc G. The towel is secured to the roller by a metal strip attached to the roller by screws at its ends, and clamped down upon the edge of the towel or passed through a hem on the towel. The rotation of the roller may be limited by arranging the spring either to be completely untensioned or to engage the inside of the roller when the towel is fully rolled up.

Abstract: 1,254,640. Protective arrangements. BANDSTAHLKOMBINAT SITZ EISENHUTTENSTADT VEB. 3 July, 1969, No. 33634/69. Heading H2K. [Also in Division G1]  An overload protective arrangement, e.g. for a motor, comprises a KWL meter 1 having a rotatable disc with a speed of rotation dependent on the power drawn by the load, means 2 to derive pulse signals from the disc of a repetition frequency dependent on the speed of rotation and an overload indicator which responds when the pulse frequency exceeds a predetermined value. The disc has markings which are scanned by a pulse scanner 2 comprising a light source and a light responsive diode. The pulses are amplified at 4 and supplied to a trigger circuit 9 the output of which is applied to an AND gate 13 and to a monostable circuit 10 also connected to the AND gate 13. The circuit 10 assumes its unstable state for a fixed period as, say, a first pulse ceases. Should the next pulse arrive while the circuit 10 is still in its unstable state then the AND gate 13 has signals on both its inputs and provides an output signal to a storage circuit 14, 15 and amplifier 16 and a relay 17, 18. A feedback signal for the trigger circuit 9 may be provided by an AND-gate 6, an amplifier 7 and an OR-gate 8. The storage circuit 14, 15 may be reset by a switch 20.

Title: Improvements in or relating to arrangements for indicating electrically the quantityof liquid in a container
IPC: H01R39/38
Filed: 1934-11-24
Abstract: 441,576. Electric signalling systems. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Nov. 24, 1934, No. 33863. Convention date, Nov. 24, 1933. [Class 40 (i)] In a system for indicating electrically the quantity of liquid in a tank, e.g. the petrol tank of an aircraft, the liquid forms the dielectric of a condenser which is so arranged that it includes either the entire quantity of liquid or a part of the liquid surrounding the "gravitational line " of the container. The gravitational line " is defined as the locus of the centres of gravity of elementary containers formed by planes parallel to the bottom of the container. As shown, a perforated and insulated plate 1b forms one plate of a condenser, the other plate of which is formed by the liquid container 1<a>. The plate 1<b> may be arranged horizontally instead of vertically. The condenser is connected in an A.C. bridge circuit formed by a second condenser 2 and resistances 3, 4 and the out-ofbalance current is passed through an amplifier 7 and rectifier 9 to operate a D.C. instrument 10. In order to ascertain the quantity of liquid in the tank the bridge is balanced by the condenser 2 which is calibrated to indicate quantity. The condenser 2 may be operated automatically under the control of the instrument 10 and may be adapted to control distant indicating apparatus which may be operated only when the quantity of liquid falls below a critical value. In a modification that part only of the liquid which surrounds the gravitional line of the container is enclosed between inner and outer condenser plates ; in addition a plurality of condensers connected in parallel may be disposed at different points in the liquid container. In the event that the container is of irregular shape, each condenser is shaped so that it conforms with the "gravitational line " of the space embraced. A calibrating condenser which is completely filled with liquid may be employed so that measurements of liquids of different dielectric constants may be effected. Several containers may be supervised individually and the sum of all the containers also may be measured.
