Title: A method of and apparatus for treating whale carcasses to prevent decay
IPC: A01K79/00
Filed: 1938-10-26
Abstract: 520,887. Preserving whales. SAEBJORNSEN, S. Oct. 26, 1938, No. 30932. [Class 49] [Also in Group XIII] To prevent decay of whale carcases the blood is withdrawn and the flesh cooled as soon as convenient after the capture of the whale, the cooling being effected either by pumping cold fluid, e.g., cold sea water or air through the body, or by the use of cooling tubes inserted into the body. The blood, drawn off through a pipe 18 by a suction pump 19, is collected in a tank 20 on the whaler and may subsequently be used for making blood meal, fodder, glue &c. The cooling, when liquid is used, is done in such a way that the liquid does not mix with the blood ; thus, pumping of sea water into the breast and abdominal cavity is carried out after the removal of the blood. The intestine and stomach are flushed out and the contents emptied through a thick tube 28. At the shore station, water with added salt or other preserving agent may be pumped into the carcase. The cooling tubes used consist of inner and outer concentric tubes; cold liquid, introduced into the inner tube, passes along it to escape into the outer tube and the liquid then flows back along the outer tube to an outlet adjacent to the inlet to the inner tube.

Title: Limit control for an alternating current motor
Inventor: MANNERS FRANK ALAN
IPC: B66C13/23
Filed: 1969-06-19
Abstract: 1,206,259. Automatic speech control. SQUARED. CO. June 19, 1969, No.30999/69. Heading G3R. [Also in Division H2] In a crane control system, movement of slider 38 in the clockwise direction from it central position, provides a reference voltage to turn on lowering control unit LX and common control unit CX as well as energizing relay 22. The impedance of static switches 1L, 2L, C, is reduced whereby induction motor 10 exerts a torque in the lowering direction. Feedback voltage from tachometer generator 35 opposes the reference voltage and tends to increase the impedance of the static switches. Under overhauling load conditions the net signal reverses whereby control unit LX is turned off and control unit HX becomes effective. The static switches 1H, 2H, are then turned off and the motor provides a counter-torque to stabilize the lowering speed. Upon return of the slider 38 to the central positon, a brake 28 is set and the motor exerts a hoisting torque for quick stoppage. When a limit switch 18 is untripped, full line voltage is impressed transformer winding 24p so that brake 28 is released. This is because transformer windings 21p, 21s have the same number of turns and have low impedance when interconnected through contacts 18b. When the motor enters the limit zone while operating normally in the hoisting direction, contacts 18a, 18b, open to de-energize the motor and set the brake. The load is lowered out of the limit zone by adjusting slider 38 to turn on switches 1L, 2L, and C. The winding 24p, is now connected across conductors L1, L2, through contact 18c, and switch 1L. Upon the switch 1L reaching a low impedance, the brake 28 releases and the load is lowered, after which the limit switch is reset to establish normal operation. If the motor is plugged when entering the upper limit zone, the brake is not set, but the motor then exerts lowering torque so that the load is brought to a standstill and lowered out of the zone. An additional safety feature prevents overspeeding, when lowering out of a limit zone, if the limit switch 18 fails to reset. The feedback voltage  from the tachometer generator increases the impedance of switches 1L, 2L, C, so reducing the energization of winding 28w and resetting the brake. The motor is then alternately accelerated and stopped for safe lowering of the load, even if the master switch is held in a lowering position.

Convention date, Oct. 25, 1928. [Class 106 (iv).] Comprises an apparatus for photographically recording sound in which a sound-induced electric current is passed through a linear opaque conductor, causing it to vibrate in a magnetic field across the path of a narrow beam of light which is inclined to the conductor at an acute angle, the angle being adjustable in accordance with the invention. As shown, the legs 17 of an electromagnet are provided with aligned longitudinal bores. A converging lens in the bore of one of these legs 17 projects a reduced image of a source of light 1 on to the central plane 3 of the light gap between the pole pieces 20. In the plane 3, the strip conductor 4 vibrates and a converging lens 6 in the bore of the second leg 17 projects an image of the partly obscured light source 1 on to the sensitized filmband 7. The conductor 4 is mounted, as shown in Fig. 7 (a section on line VII-VII of Fig. 6) and in Fig. 8, (a section taken at right-angles to Fig. 7) in a sliding frame of non-magnetic material consisting of two parallel side parts 21 connected at one end by two transverse members 22, one end of the conductor 4 being secured between the transverse members 22. The other end of the conductor 4 is secured to a pin 23 extending into a sleeve 24 and a spring 30 imparts to the conductor 4 the required tension which may be adjusted by a second spring 27 acted upon by a stud 28 on a nut 29 screwed on the sleeve 24. On the wedge-shaped pole-pieces 20 a casing 31 of non-magnetic material is fitted and provided with an opening to receive and guide the side part 21 of the sliding frame. The casing 31 together with the pole-pieces may be rotated around the axis of the legs 17 to permit adjustment of the angle between the vibrating conductor and the image of the source of light.

Abstract: 261,556. Mitchell, A., and Smith, J. W. Dec. 10, 1925. Stays for windows pivotally mounted about the lower edge comprise an attachment plate P which is secured to the side frame and carries the stay arm P<1> and a pivoted stop P<2> therefor, and a guide member A secured to the window, the plate A having means such as a pin A<2> which, as the window closes, disengages the stop from the end of the stay to cause the stay-arm to hang vertically alongside the window frame. The lower edge of the stay is notched at P<3> for engagement with the edge P<5> of a recess in the member A to secure the window in an adjusted position. The stay-arm is held at an angle to the window frame by the pivoted stop-piece P<2>, as shown in Fig. 5, and the stay is lifted by hand to secure a fresh engagement of one of its notches with the member A. When the window is moved to its closed position, the pin A<2> pushes aside the stop member and allows the stay to fall into its vertical position. The pivoted member B is adapted to engage over the stay to secure it when the window is in the open or closed position. A hinged beading may be provided to close the gap between the window and its frame.
