Abstract: 1514261 Weighing apparatus GEORGE SALTER & CO Ltd 12 March 1976 [13 March 1975] 10406/75 Heading G1W Weighing apparatus comprises a load displacement member 2, Fig. 1, which moves in accordance with the load being measured, and weight measurement means operatively controlled by the load displacement member to provide an output indicative of the load, control of the weight measurement means being effected by a movable follower 4 which follows the load displacement member, the movable follower being driven by a drive means 3 and having a sensor element 20, and locking means 12-19 being provided to arrest movement of and maintain in position, the follower upon establishment of abutting contact between the sensor element and the load displacement member. In Fig. 1, the follower is a lever 4 pivoted about a fixed shaft 5 and having a sector gear driving a digital display 6, 11. The sensor element is an escapement wheel 20 having pallets 19 engaging a star wheel 18 which is driven as lever 4 rotates by means of a gear train 13-17 meshing with a gear 12 fixed to fixed shaft. When member 2 is displaced the lever pivots to follow it until wheel 20 touches it and prevention of oscillation of wheel 20 locks the gear train to lock the lever in position. When the load is removed, the lever remains in the locked position until the reset lever 25 is pressed, the shaft of gears 15, 16 being mounted in vertical slots to allow those gears to rise and interrupt the gear train during return movement of the lever to the zero position. In a modification, Fig. 5, the abutment between escapement wheel 20 and member 2 which locks the gear train occurs on a lateral surface of the member 2. In the bathroom scales of 2, the load on platform 102 is applied via levers to plate 2a acting on the measurement spring 1a, plate 2a acting as the load displacement member. Follower lever 4a is pivoted on shaft 5a and is driven to follow plate 2a by a spiral spring 3a. Escapement wheel 20a is coupled to a gear 12a fast with shaft 5a via gears 13a, 14a, 40, 41, 42, 43, 44, 45, 115a, 16a, 17a and star wheel 18a and the digital indicators 6a, 11a are driven by gears 40, 44. In the modified bathroom scales of Figs. 3 and 4, the sensing element comprises a fork member 60 pivotally mounted on lever 4b and having a contact member 75 rigidly attached for contacting the load displacement member 2b. Fork member 60 co-operates with an escapement wheel 70 which directly drives the digital display, and which is driven from fixed gear 12b by gears 13b, 14b, 15b, 16b, 17b, 64, 65. The teeth of escapement wheel 70 and the ends of the fork 60 are inclined to act as a ratchet to permit resetting to zero by means of lever 25b. The follower lever may be driven by a gravity or electric motor instead of a spring.

Title: Impregnation of porous solids such as wood chips with liquids
IPC: D21C1/00
Filed: 1960-03-25
Abstract: Porous materials, such as wood chips, having a moisture content are impregnated with liquids by heating the material with radio frequency heat to cause an increase in the vapour pressure of the moisture in the material and in the pressure of any air in the pores of the material and to expel all or part of the moisture in the latter, and immediately bringing an impregnating solution, at a lower temperature than that of the material, into contact with the surface of the material, the heating of the material being dicontinued before the material is contacted with the solution. The process may be used for the chemical pulping of wood, or the impregnation of wood waste with a solution of an adhesive.  The process of the invention increases the rate and depth of impregnation of porous materials with liquids.

Title: Multi-channel telemetering device
IPC: C03C25/143
Filed: 1950-05-02
Abstract: 668,453. Telemetering systems. DUTILH, J. R. H. May 2, 1950. [May 10, 1949 ; March 25,1950] No. 10757/50. Class 40 (i). [Also in Group XXXVI] A constant current source 8, Fig. 1, e.g. a pentode, is periodically reversed at 9 to feed over a manually operable switch 37 any one of circuits 2, 21, 2<SP>11</SP> each including a resistance 3 to be measured, the resistance 3 being shortcircuited for one direction of current flow, so that the voltages measured at 14 indicate the value of the resistance. As shown in Fig. 1, a relay 4 operates for one direction of current flow to short circuit the resistance 3 ; alternatively, a rectifier 13, Fig. 3, may be used to by-pass the resistance 3 for one direction of current, a further rectifier being connected to compensate for the contact resistance. For one direction of current flow, the voltage across 11, 12 is IR L  + IR R  -IIRx where R L , R R , R x  is the resistance of the leads, the relay (or rectifier) and the unknown resistance ; for the other direction of current flow, the voltage across 11, 12 is -(IR L , + IR R ); if the periods of reversal are equal, the average voltage is proportional to R x  and can be registered by an instrument 14 of suitable time-constant. If the periods of reversal are unequal, the instrument can be adjusted to read zero when the resistance 3 is short-circuited, so that the reading when the resistance is in circuit is related to R x . In another arrangement, the voltage arising when the resistance is shortcircuited, charges a condenser 25, Fig. 5, which, on reversal of the current, is placed in series with the voltmeter 28 which thus registers the difference between the voltages developed when the resistance is in and out of circuit. Specifications 400,289 and 601,541 are referred to.

Abstract: 1365003 Electromagnetically released switches PENTACON DRESDEN KAMERA-UND KINOWERKE VEB 9 March 1972 11035/72 Headings G4D D6Y D6A1 and D6M1 A print pre-selector switch for controlling the number of copies produced by a printing apparatus comprises a toothed counting disc I, having a location device 15, an electromagnetically actuated stepping member 14 for engaging the said teeth to rotate the disc 1 when the teeth are in the region of member 14, a stepping disc 6, and a latch 7 arranged to engage a stop face of the disc so as to allow a switch 12 to remain open, said switch being held closed when the latch is withdrawn to rest against the face of the disc 6, the disc being rotated by a bias spring 5 towards a stop pin 10 on the counting disc. For single print the latch is withdrawn using button 11 causing the disc 6 to abut stop pin 10, Fig. 3. A copy is printed and switch 16 is closed briefly to energize the magnet 13, the member 14 engaging tooth 4 on disc 6, and causing said disc to "step" clockwise and release switch 12 as member 7 relatches. For multiple print, the selector 2 is rotated, so as to rotate the disc 1 anti-clockwise to a set position corresponding to the copies required. The latch 7 is withdrawn to start the print process and disc 6 now rotates to engage stop 9, the tooth 4 being clear of the stepping member 14. After a copy is printed the member 14 engages a counting disc tooth and steps the disc clockwise until, after all but one of the required copies has been produced, it engages the last counting disc tooth. At this time the pin 10 engages the stepping disc and moves it during this step to the position of the activated single print sequence, Fig. 3. The last copy is then produced. The member 18 on the counting disc provides "infinite copying" by being turned to engage and open switch 17, thus rendering the electromagnet inoperative.
