Title: Solid or water quantity measurement apparatus using microwaves
IPC: G01N22/00
Filed: 1977-04-13
Abstract: 1521656 Determining solids content of liquid ANRITSUDENKI KABUSHI KIGAISHA 13 April 1977 [26 April 1976] 15261/77 Heading G1N An apparatus for determining the solids or water content of milk comprises a waveguide 13 defining a micro-wave oven 14 fed by a magnetron 11 and terminated in a dummy load 17 and, enclosed within the waveguide a weight detection plate 23 connected with a weighing balance 27. A sample heating plate 15 is supported by the plate and water evaporated from the sample is discharged from the waveguide through apertures 18 by a fan 19, the air being supplied through inlet openings 20. In use a filter paper is first heated by microwave radiation on a plate support 40 and the sample plate 16 with its heated filter paper is transferred to the weight detector plate 23 and a new filter paper and plate 15 is put on the detection plate 23. A button 35 is pressed and the tare weight Wo i.e. that of filter paper and detection plate, is determined as an analog signal, ditigized in A/D converter 28 and stored in a memory 29. One gram of milk is then applied to the filter paper on the detection plate. The measurement button 36 is then pressed and the total weight W 1  of the tare and sample is recorded in the memory. After a delay determined by a delay 37 a timer 38 is actuated to initiate energization of the magnetron and fan for a set period. When the timer has timed out a command circuit 30 signals the memory to store the weight W2 of the tare and dried sample. A calculator 31 calculates percentage water and/or percentage solids from the weight determinations Wo, W 1 , W 2  which ratios are displayed 32 and printed out 33. The water temperature in the dummy load 17 is maintained constant using a thermostatically controlled tank 21 and pump 22. In an alternative embodiment, Fig. 7 (not shown) the locations of the electric field maxima are determined where a standing wave is created by reflections from the dummy load and the plates 15, 16 are disposed at the locations of successive peaks.

Abstract: 562,006. Mining machines. MAVOR & COULSON, Ltd., MAVOR, J. B., and GALLOWAY, W. S. Nov. 10, 1942, Nos. 15864 and 18076. [Class 78 (iv)] [Also in Group XXI] A mining machine for transferring coal from the face to an adjacent conveyer follows in the path of the removed coal so that the conveyer B may be disposed at a minimum distance laterally away from the seam A. Fig. 2 is a plan view of such a loader comprising a sweeping arm F, or a plurality of such arms located one above the other, which is given an oscillating motion by a medial rotating pivot 6 and a link-suspended end pivot. A detachable plate 18 pushes the broken coal on the head G sideways to a shoot H down which it falls on to the conveyer B located beyond the pit-props C. A rotating disc 4 carrying the pivot 6 is mounted on a jib E carried by the motor-enclosing body D of the machine. The jib E is rotatable about an axis 12 on the body, and can be locked in a position on either side of the same so as to permit both right and left hand working. The bracket 5 is attachable to either side of. the jib E to allow of this, and the pusher 18 can also be reversed. Fig. 4 shows in plan' a similar gathering machine combined with a coal cutter. Cutter chains P, Q make horizontal grooves at top and bottom of the seam, and a third chain forms a rear shear cut L parallel to the . coal face. A vertical crank-shaft 11 operates one or more pusher plates 13 in the above-described manner, and another crank-pin on the shaft 11 imparts a wedging and levering motion to a breaker arm T which, by entering the cut L, effects disruptive pressure on the under- and over-cut coal. In this form the conveyer B is located between the seam A and the props C.

Title: Improvements in or relating to comb-type band-pass filters
IPC: H03H9/62
Filed: 1955-06-03
Abstract: 784,689. Electromechanical filters. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. June 3, 1955 [June 3, 1954], No. 16029/55. Class 40 (8). A "comb-type" electromechanical filter comprises magnetostrictive input and output transducers coupled by a bar which resonates in a torsional mode. The filter is designed to transmit a fundamental frequency together with a large number of harmonics so that the transmission characteristic curve has the appearance of a comb. The bar 2, which has magnetostrictive properties, extends between the input (left-hand) end of the filter and the output end which is not shown but is similar in construction to the input. The input transducer comprises a coil 3 provided with a magnetic yoke 9, magnetic polarization of the active part A-B of the bar 2 being provided either by a permanent magnet (not shown) or by a D.C. current in the coil 3. According to the invention the active portion A-B of the bar 2 at both the input and the output ends is twisted beyond the elastic limit of the material through an angle sufficient to ensure that substantial torsional oscillations occur together with the longitudinal oscillations associated with the magnetostrictive effect. Firmly clamped metal jaws 26, 27 of thickness small compared with the acoustic wavelength cause reflection of the torsional waves but allow transmission of the longitudinal waves which are absorbed by a closely-fitting rubber sleeve 7. Stationary torsional waves are generated in the bar 2 which is arranged to resonate in a torsional mode at the frequency of the input applied to the coil 3. The bar 2 may be circular, rectangular or square in section and may be constructed entirely of a magnetostrictive material or may be magnetostrictive only near the input and output coils. The bar is firmly held at either end by clamps 8 at least one of which may be provided with a tensioning device comprising a holding device 16 actuated by a screw 13.

Abstract: 291,459. Siemens & Halske Akt.- Ges. June 2, 1927, [Convention date]. Copying-teleqraphs. -A drum carrying a sensitized p h o t o - graphic sheet for use in picture - telegraph receivers or oscillographs is provided with a light-tight casing to enable it to be positioned in daylight. The drum c carrying the photographic film is fitted with a hollow cone e which takes on to the obliquely truncated conical head b of a shaft a driven, in the case of a copying-telegraph receiver, bv a synchronous motor, to which it can be coupled by a clutch as described in Specification 272,167. A pin f and slot ensure a correct phase relation between the drum and the shaft. The drums c and photographic film are inserted, in a dark-room, into a casing or casket g through the lid l of which passes a bolt p with knurled head o. The bolt p is screwed into a bush p<1> formed on the drum. The casket and drum are then inserted into a fixed outer casing h coaxial with the shaft a, and the shutter k is moved by turning the rotatable lid l of the casket, to which lid the shutter is attached. A light pencil can then reach the photographic film through registering vertical slots i in the casing h and casket g, these slots being uncovered by the removal of the shutter k. The casket g remains stationary but the drum c is released for rotation by unscrewing the bolt o, p, which is then raised clear of the drum by the spring q. When the casket is free of the casing h before being inserted therein, the lid l and shutter k are secured against rotation by engagement of a spring-pressed pin r with a hole in a flange u in the casing. The pin is pushed out of the hole, when the casket is in position, by a fixed pin on the flange w of the casing which engages with the hole, and the lid and shutter can then be turned. When the shutter is in the open position a nose w integral with the lid engages under a catch x, so that the casket cannot be withdrawn till the shutter has been closed. When a record has been taken the lid l cannot be turned back to release the casket until the bolt o, p, has been screwed into the bush p<1>, owing to engagement of a lever y on the lid in the hole j in the flange u of the casket g. This engagement is released by the screwing down of the bolt o, p.
