Patent DK-85981-A (DK)
Inventor: JOHANSEN K H S
IPC: G01V/
Filed: 1981-02-26
Abstract: In order to scan a region 7-8 for the passage of an object, a parallel light beam 10 is sent out from a transmitter 1, 2 through the region from the side. The beam's reflection will be captured by a receiver with optical systems 3, 6 having focal points f subscript 1, f subscript 2 at the light beam's 10 upper intersection with one boundary 7 of the region and the light beam's 10 lower intersection with the other boundary 8 of the region, respectively. This assures a sensitivity that is evenly distributed throughout the entire region 7-8. At the same time, the sensitivity becomes zero outside of this region. Thus, it will be possible to register any given motionless object with great certainty in the region, and the receiver will not receive perturbation signals outside of this bounded region. <IMAGE>
Patent DK-89486-A (DK)
Inventor: HOFMANN HELMUT
IPC: A01K1/02
Filed: 1986-02-26
Abstract: Farrowing box, by means of which the requirements of the animals (farrowing sows and piglets) before, during and immediately after farrowing (approximately 8 days) are not only met better than hitherto, but are met "completely". The farrowing box is equipped with all technical features, which are specifically adapted to the requirements of the piglets in the first week of life. On the basis of the conventional farrowing box for the entire suckling period a "special farrowing station" has now been developed as a so-called week station for the first 8 days of life and hence the risk phase. At the end of this risk phase the piglets and the sow can be transferred to a usual farrowing box (better termed a pig- rearing box). The farrowing station is thereby free again after 5-10 days and ready for the next highly pregnant farrowing sow. An operation which with 5 weeks' suckling time hitherto might have 10 farrowing boxes in service will be able to replace two farrowing boxes with "farrowing stations" and in so doing fully meet the requirement. The piglets are confined to the warm nest 3 each time the sow 38 stands up, and constantly and automatically receive fresh water or electrolyte solution or milk in the trough. This is automatically cleaned every time before refilling. The entire station washes itself and the farrowing sow fully automatically, and the station is self-disinfecting. <IMAGE>

Title: Improvements relating to electric block interlocking signalling systems for railways
IPC: B61L23/12
Filed: 1924-01-02
Abstract: 221,404. Kershaw, A. G., and Westinghouse Brake & Saxby Signal Co., Ltd. Jan. 2, 1924. Signalling-instruments. - Cancellation of permission for a train to pass and resetting of the signalling instruments and signals to normal position are provided for by the use at each station of two switches operable by the signalman and a switch under the stationmaster's control. The drawing shows one station B on a double track section with an instrument of known type for controlling traffic in both directions using separate line wires 30, 31, for up and down traffic and a third line wire 32 for bell signals and cancellation for both tracks. Line wire 30 includes the electromagnetically-controlled switch 33 at station @ and at station A (not shown) a switch similar to switch 34. Line wire 31 includes at station A a switch similar to switch 33. Otherwise the instruments and signal circuits are unaltered. To cancel a train accepted by station B from station A, the operator at A operates switch 34, and thereby transmits a current from his battery 40, over the bell wire 32, to station B to energize the polarized relay 29. This current is reversed from that used for bell signalling and the relay armature connects the resistance 54 in series with the bell 11. Closure of the station master's switch 35 thus energizes the magnet 55 and the signalman at B is able to operate the switch 33 and energize the releasing magnet 19 to produce the same results as a train passing out of the section over the treadle contacts 8; the line wire 30 is broken down while switches 33, 34. are operated.

Title: A circular loom for the production of closely woven fabrics
IPC: D03D37/00
Filed: 1948-01-02
Abstract: 651,641. Circular looms. SAINT FRERES. Jan. 2, 1948, No. 143. Convention date, Jan. 17, 1947. [Class 142(ii)] Spiked wheels which beat-up the weft in a circular loom rotate at a higher speed than the shuttles. The number of spiked wheels exceeds the number of shuttles. A shuttle 1 travels on a shuttle race 2 and lays a weft thread which is beaten-up by spiked wheels 4. The wheels 4 are mounted on a revolving ring 6, and some wheels rotate by reason of their pressure on the warp threads as the ring 6 revolves, while others are positively rotated. The positively rotated wheels ensure that the warp threads maintain their correct radial positions. The fabric is prevented from slipping back after the beat-up by spikes 7 on the inside of the tube 3. The spikes may be secured to a backing of webbing, leather or india rubber.

Title: Electrical means for reproducing motion
IPC: G08C19/48
Filed: 1944-01-04
Abstract: 580,647. Electric control systems. BENDIX AVIATION CORPORATION. Jan. 4, 1944, No. 154. Convention date, July 11, 1942. [Class 40 (i)] A mechanism for transmitting motion comprises a transmitter haying a single winding energized with alternating current and a plurality of output, windings, the voltages induced in the output windings being combined with an alternating reference voltage, rectified and applied to the windings of a direct current receiver so as to set a permanent magnet rotor to a position corresponding to the direction of the field produced by the input winding of the transmitter. In Fig. 1, voltages induced in coils 7, 8 and 9 are varied with the angular position of coil 6 and these are separately combined with the alternating supply voltage and applied through full-wave rectifiers 21, 22 and 23 to stator coils 11, 12, 13 on the receiver, the rotor 14 controlling an indicator 16. In Fig. 2, the transmitter is of the type described in U.S.A. Specification 2,269,602, having an exciting winding 32 fed with alternating current and three output windings 36, 37, 38 wound on a core 31 of highly permeable magnetic material and a permanent magnet rotor 40. The voltages generated in the output windings are mostly second harmonics of the frequency of the exciting current. The output windings are Y-connected and each one, e.g. 36, is connected to one side of a pair of rectifiers 52, 53, the alternating source being connected through a frequency doubler to the other side of the rectifiers as shown so that the sum of the reference voltage and the output voltage is applied from one rectifier 53 to one stator coil 44 of the receiver and the difference between the reference voltage and the output voltage is applied from the other rectifier 52 to another coil 43 on the same core, so that the resultant voltage equals twice the output voltage. To transmit the indications of a magnetic compass, the rotor 40 may be replaced by the compass needle. Similarly, the rotor may be dispensed with and the stator placed in the magnetic field of the earth when the transmitter is to be used as an earth inductor. In a modification, Fig. 3 (not shown), employing the same type of transmitter, the output windings are not Y- connected and each is connected to a rectifier through one winding of a transformer, in the primary of which the reference voltage is applied. Since the rectified voltages have no phase sense, a D.C. voltage equal and opposite to the D.C. component of the reference voltage is applied to the stator windings of the receiver in order to create a proper magnetic field.

Filed: 1941-01-06
Abstract: 541,323. Photographic shutters. KODAK, Ltd. Jan. 6, 1941, No. 214. Convention date, Jan. 5, 1940. [Class 98 (i)] A photographic shutter comprises a single blade eccentrically pivoted on a pivoted cover plate which, when moved to uncover the exposure aperture, tensions a hairpin spring connected to the blade and to a fixed stud so located near the path of travel of the shutter pivot that when the latter passes it the spring is released and moves the blade relatively to the cover plate to make the exposure. As shown, the shutter comprises a cover plate 14 pivoted on a stud 4 carried by a bracket 5 and operated by a trigger 3 rigidly secured to it. The shutter blade 20 with the exposure opening 21 is pivoted on a stud 23 carried by the cover plate 14, and is acted on by a hairpin spring 24 the ends of which are attached to a fixed pin 9 carried by the bracket 5 and to a lug 22 on the blade. When the trigger 3 is depressed against the action of a spring 16 the cover plate 14 is moved counterclockwise until an opening 25 in it is opposite the exposure opening 15. During this movement, the pivot 23 is carried past the fixed pin 9, the spring 24 being thus first tensioned and then allowed to rotate the blade 20 anticlockwise to make the exposure. On release of the trigger, the cover plate moves first to cover the opening 15 before the blade is returned by the hair spring. For time exposures, a lever 31 is rocked by pulling out a bar 26 to which it is pivotally connected, a lug on the lever then engaging a lug 35 on the blade and arresting the blade in the open position.

Abstract: 970,047. Boundary layer control. T. HELMBOLD. Jan. 5, 1961 [Nov. 19, 1960 (2)], No. 474/61. Heading F2R. [Also in Division F1] A device for stabilizing a standing vortex comprises a guiding body formed with a concave surface adapted to lie close to the periphery of the vortex and at least one duct or passage leading from an inlet on the concave surface to an outlet which is downstream of the inlet and is in a region where during operation the pressure is lower than at the concave surface. Fig. 5 shows a diffuser provided with concave members 1, 1a and with slot-forming rings 14, 14a which may be of adjustable position. As shown in Fig. 4a, the flow through the diffuser generates a toroidal free vortex at, each concave member 1, la, the vortex allowing the use of a large diffuser enlargement angle without breakaway of flow from the diffuser walls. The annular slot 2 formed between each concave member 1, 1a and the corresponding ring 14, 14a connects the concave surface of the member 1, 1a with a region of lower pressure, whereby air is drawn through the slot 2 from the vortex and returned to the periphery of the vortex at the region of lower pressure. This stabilizes the position of the vortex. Each vortex may be divided into shorter vortices by means of discs disposed substantially radial to the diffuser axis and corresponding in shape and size to the cross-section of the vortex. The discs may be rotatable about their axes. Each slot 2 may extend over a part only of the circumference of the diffuser. The members 1, 1a may be separate from the body of the diffuser and mounted inside it instead of being formed by the body as shown.
