Title: Improvements in sliding panel actuators
IPC: E05F15/60
Filed: 1967-04-13
Abstract: 1,113,008. Actuator for sliding panels. SOCIETE D'ELECTRONIQUE ET D'AUTOMATISME. 13 April, 1967 [20 April, 1966], No. 17024/67. Heading E2M. An actuator device, for assisting a human operator in moving a heavy sliding panel for displacement along a substantially horizontal track, comprises the combination of an elongated multipolar field structure extending over the length of the track and defining a correspondingly extending linear magnetic airgap, a flat elongated armature winding secured to a side of the framework of said panel parallel to the track and located within the airgap, and electric current transducer means carried by the field structure and bearing against the armature winding for the supply of said armature winding with an electric current the polarity of which determines the direction of the magnetic attraction between the armature and the field structure in the direction of the track. By way of example, in Figures 1 and 2 the width of a sliding window panel having panes 5, 6 is indicated by A or B. The lower framework 4 of the panel is secured to a plate 3 which, together with arm 2, forms an elongated stirrup member (e.g. of iron). Beneath plate 3 are secured carriers 7 for rollers 8, said rollers bearing on roller path 9 extending over the distance A+B-C. The roller path 9 is supported from gulley 10, which rests on the wall wherein the window is mounted. Under plate 9 is secured plate 11 of a coercive hard magnetic material in which a series of alternate magnetic polarity poles have been magnetized along the length thereof. The plate 11 consequently constitutes the field member of the actuator; the linear magnetic airgap is defined between the field plate 11 and the facing soft magnetic plate 2; and plates 9 and 11 are the multipolar field structure. Within the linear airgap is arranged an armature winding 1 (illustrated by Figure 3 - not shown) applied over the airgap face of plate 2 and having the same length as the plate. Pairs of brushes 12 are provided to constitute electric current transducer means for the supply of current to the armature. On operating a switch, either manually or automatically, an electric current is applied in the armature such that the magnetic attraction between the winding and the fixed field structure either moves the window to the open position or so reduces the apparent weight of the window that it can be moved with a minimum of effort. The current is reversed for closing the window.

Title: Random stream materials sorter
IPC: B07C5/342
Filed: 1963-05-02
Abstract: 986,177. Fluid-pressure control valve. K. & H. EQUIPMENT Ltd. May 2, 1963 [May 25, 1962], No. 17297/63. Heading F2V. [Also in Divisions G1, G3, H3 and H4] Air from an inlet 88 is prevented from flowing to an outlet 90 by a light valve member 91, made for example of a plastic, which is retained in its lower position by pressure from an auxiliary air inlet 103 which communicates with the upper face of member 91 by way of a passage 105 through a plunger 96 of an electromagnet solenoid 95, a chamber 106 and a passage 107. Energization of the solenoid raises the plunger 96, cuts off the auxiliary air inlet by a valve 97 and opens a valve 98 to allow chamber 106 to communicate with an air exhaust outlet 104 and thereby remove pressure from the upper face of member 91. Air from inlet 88 then tends to flow below member 91 which by virtue of its light weight is moved rapidly to its upper position. The auxiliary air inlet may be at the same or a slightly elevated pressure with respect to inlet 88. The area of member 91 over which the auxiliary air supply operates is made greater than that over which the air from inlet 88 operates and is increased artificially by forming shallow slots 108 across the upper face.

Title: Improvements in automatically operated electromagnetic fan driving clutches for internal combustion engines
IPC: F01P7/08
Filed: 1951-07-23
Abstract: 687,643. Operating clutches. BOSCH GES., R. July 23, 1951 [July 31, 1950], No. 17361/51. Class 80 (ii). [Also in Group XXVII] An electromagnetic clutch 10 energised from a battery 15 and disposed between a cooling fan and a fan driving shaft, is engaged, e.g. by springs 13, in the de-energised condition to drive the fan, and a relay 14 in the circuit of the clutch and open in its de-energised state has an energising winding 17 controlled by a thermally-operated switch 18. Any defect occurring in the switch or the relay winding when the clutch is disengaged causes the relay circuit to open so that the clutch becomes de-energised. During operation if the engine temperature falls below about 80‹ C. the switch closes and the clutch winding 12 is energised to disengage the clutch against the springs 13 so that the fan comes to rest. In a modification, a resistance is inserted in the switch circuit which is open when the engine is cold, the relay being energised through the resistance and maintaining the circuit of the clutch winding closed so that the clutch is disengaged.

Title: Process for the production of non-rigid containers filled with liquids or pastes
IPC: B65D75/48
Filed: 1950-07-12
Abstract: 675,073. Producing filled containers. RADO, L. July 12, 1950, No. 17444/50. Addition to 599,174. Class 94 (i). An improvement in or modification of the process for the production of filled containers of thermoplastic material described in the parent Specification, comprises heat-sealing the longitudinal, registering edges of two strips or a folded strip of thermoplastic material to .form a tube, sealing the end of the tube, filling it with a liquid or elastic material, applying lateral pressure at spaced points along the tube to displace the contents and cause the tube walls to make contact thereat and after each pressing operation generating heat by means of the pressing tools to weld together the contacting walls of the tube. The containers are then separated from the tube by cutting through the welds. As shown, strips 1 and 2 of polyviynl chloride are fed intermittently from supply rolls, and their superposed longitudinal edges welded together by pressing tools 3-3c, to which a high-frequency voltage is applied. After formation of the initial end seal 7, a quantity of liquid or paste exceeding that required for a single container is introduced into the tube through a pipe 11, the tube advanced one step and its walls pressed together to displace the filling by a pair of jaws, 6, 6b to which a high-frequency voltage is subsequentlyapplied to weld the contacting walls. The tools 3-3c and 6, 6b and the filling, mechanism are operated in synchronism with the feed of the strips, the length of the tools 3-3c. being greater than the distance by which the strips are advanced at each step so that the longitudinal welds overlap. The filling of the tube may be assisted by inclining the tube.

Title: Control system for adjusting a first voltage toward equality with a second voltage
IPC: G01S1/02
Filed: 1948-06-29
Abstract: 655,187. Potentiometric voltage measurement. HAZELTINE CORPORATION. June 29, 1948, No. 17447. Convention date, July 11, 1947. [Class 37] [Also in Groups XXXVII and XL (c)] In a device for comparing an unknown unidirectional potential e 2  (which may be developed by a known radar interrogatorresponder 12 as a measure of the range of a transponder carrying aircraft 13), with an adjustable unidirectional potential e 1  derived from a variable potentiometer 17, the potentials are respectively fed to the cathodes of the diode rectifiers 26, 27 through resistors 20, 24 and the anodes are connected to a generator 22 developing a periodically varying voltage (either sinusoid or saw-tooth), whose peakamplitude periodically exceeds e 1  and e 2  and whose frequency is greater than the highest expected variation periodicity of e 2 . The rectifier anodes are also connected through a resistor 31 to the anodes of the gas discharge tubes 29, 30 whose control electrodes are normally biassed to cut off and condenser coupled to the respective rectifier cathodes. The discharge tube cathode circuits energize oppositely rotating D.C. motors which are mechanically intercoupled to rotate the potentiometer slider and a scale pointer indicating the value of e 2  as a measure of the aircraft range. Initially, if e 2  is greater than e 1  the rectifiers and discharge tubes are non-conducting at the beginning of a positive half-cycle of the generator voltage, but when the peak value of the latter exceeds e 1  the rectifier 27 conducts and triggers the discharge tube 30 and pulse energizes the motor 41 for the rest of the positive half-cycle, after which the discharge tube is de-energized. Meanwhile, rectifier 26 becomes conducting when the generator peak voltage exceeds e 2 , but the discharge tube 29 does not trigger, due to the known properties of parallel discharge tubes and the voltage drop across the anode resistor 31. The cycle recurs on each successive positive halfcycle of the generator voltage so long as e 2  is greater than e 1  and the motor 41 rotates in a series of steps to re-adjust the potentiometer until e 2 =e 1 . Then either discharge tube triggers indifferently on positive half-cycles so that the motors are alternately pulse energized to hunt the potentiometer about the position of equality. If e 1  becomes greater than e 2  the rectifier 26 conducts, the discharge tube 29 triggers, and the motor 40 is pulse energized on successive positive half-cycles to re-adjust the potentiometer in the opposite sense until e 1 =e 2 . The device operates similarly when e 2  varies at any periodicity appreciably less than that of the generator voltage.
