Title: Hatches, especially ships' hatches, having associated hatch covers
IPC: B63B19/19
Filed: 1964-05-29
Abstract: 1,010,940. Operating hatch covers; stud and socket fastenings; catch fastenings. BERGENS MEK ANISKE VERKSTEDER A/S. May 29, 1964 [June 15, 1963], No. 22269/64. Headings E2A, E2B and E2M. [Also in Division B7] In a sectional hatch cover (see Division B7) the sections are hinged together at 15 by a hydraulic rotary motor (not shown) such that on initially operating the motor, section 12 will pivot at its edge about stop device 16 while the left-hand edge of section 13 is provided with roller 17 which rolls on coaming 10. This movement continues until roller 17 slides into recess 18 (see solid lines in Fig. 2). The motor is then adjusted so that the sections are pivoted into the closed hatch position, i.e. the right-hand end of section 12 is released from device 16 and rolls to stop device 20 (see dotted lines in Fig. 2) where it is locked in position. The motor is then adjusted to fold the sections together again. This draws roller 17 from recess 18 and pivoting is continued until the sections are folded together (see chain dotted lines in Fig. 2). The right-hand end edge of section 12 carries a bearing pin 19 and a roller 21 (see Fig. 5). Normally roller 21 is located in a recess 22 in the coaming so as to rest on a rail piece 23 which is supported by a member 24 of jack 25. When the end edge is to leave device 16, rail piece 23 is raised flush with portion 26 of the guideway of the coaming. At the side of the recess 22 is located a bracket 27. Pin 19 is received in a slot in said bracket such that on raising of rail piece 23, pin 19 is free to move out of the slot. In order to ensure, that this only occurs when the sections are positioned as shown in full lines in Fig. 2, a half of the pin is cut away (Figs. 3 and 4, not shown). Stop device 20 comprises a vertically mounted bracket plate 31 carrying an angle arm 34 and a locking arm 38. When pin 19 is moved into slot 32, angle arm 34 will be pivoted in a clockwise direction such that branch 35 will lift arm 38 the locking face of which will bear against branch 35 and hold it fast (Fig. 7, not shown). At this instance opening arm 43 on section 12 is disposed on the left of pin 40. However, the bearing pin 44 of the opening arm 43 will be pivoted further upwards and further towards the right. Just before the sections reach their final vertical position, arm 43 passes over an extension of pin 40 and hangs down vertically to the right of pin 40. When the hatch sections are to be lowered again, the arm 43 is pivoted in the anticlockwise direction until it bears against boss 45. Continued movement of section 12 will cause the arm to bear against an extension of pin 40 so that locking arm 38 is pivoted in an anticlockwise direction. This allows angle arm 34 to pivot under gravity in an anti-clockwise direction and thus allow pin 19 to move to the left.

Abstract: 1502679 Monitoring the state of a patient SIEMENS AG 22 May 1975 [26 June 1974] 22380/75 Heading G1A In a device for monitoring the "state" of a patient both the reflected R and transmitted T light from a source 5 (bulb or L.E.D.) are simultaneously monitored by photo diodes or phototransistors 6 and 7, and if their ratio R/T exceeds a predetermined boundary value an (acoustic) alarm is activated.  The light source 5 is modulated by means of an impulse generator and energizing stage 11. Both the reflected light signal R (influenced by the blood capillaries) and the transmitted light signal T (influenced by the pulmar finger artery 4) are amplified. Then they are frequency filtered 12, 13, demodulated 14, 15 and further amplified and frequency filtered 16, 17. The ratio of the signal is then found by a ratio former 18 whose output may be fed directly to a comparator 19. The comparator can be set to a predetermined boundary value of amplitude by an input setting device 35. If a switch 23 is closed and the boundary valve is exceed (or not reached/passed) then an alarm activating output signal passes via a phase shifting delay device 27 to the alarm 21. The device may be adapted as shown to simultaneously monitor the pulse rate f, the rate of charge of the pulse rate df/dt, or the rate of change of the R/T ratio when closing any of a number of switches 24, 25, 26 and opening switch 23. These valves are all compared with respective boundary valves by units 29, 31, 33 whose outputs supply an AND gate as shown.

Title: Improvements in or relating to gyroscopic pendulums for finding the gravitational direction or horizon on vehicles or similarly moved bodies, with an apparatus for compensating the influence of direct or centrifugal accelerations
IPC: G01C19/44
Filed: 1931-08-11
Abstract: 382,343. Gyroscopic apparatus. GES. FUR ELEKTRISCHE APPARATE, 44, Wilhelm von Siemensstrasse, Marienfeide, Berlin. Aug. 11, 1931, No. 22717. Convention date, Aug. 12, 1930. [Class 97 (iii).] A gyroscopic pendulum suspended from two horizontal axes in the longitudinal and transverse directions respectively of a vessel and provided with one or more auxiliary gyroscopes which are arranged to produce a transverse angular momentum vector proportional to the speed of the vessel, has equal moments about both axes so that alterations in the direction and magnitude of the angular moment vector correct the pendulum for centrifugal accelerations and alterations in speed. In the form shown in Fig. 1, a main pendulous gyro K with vertical axis is carried by pins q-q in a ring, supported in bearing blocks b<1>, b<2> by the pins l-l which are arranged parallel to the longitudinal axis of a ship. The auxiliary gyroscope k pivots on pins z-z, parallel to the axis l-l, in a ring r fixed on the casing of the gyro K. The motor m is geared to a sector s fixed to the gyro k and causes the axis of the latter to make such an angle alpha with the vertical that a horizontal component of angular momentum, proportional to the velocity of the ship, lies athwart the apparatus. Fig. 2 shows an arrangement adapted to stabilize about the ship's transverse axis q-q only. The two oppositely running main gyros K<1>, K<2> are mounted in lugs h<1>, h<2> depending from the platform P and are geared together by toothed sectors u<1>, u<2>. The platform P is mounted in transverse pivots a-a in a horizontal ring r<1> and in longitudinal pivots in a vertical ring r<2>. The ring r<1> is supported in standards b<2> by longitudinal pivots and the ring r<2> is mounted by vertical pivots z<2>-z<2> in a vertical ring v<3> pivoting on a transverse axis z<3>-z<3>. The auxiliary gyros k<1>-k<2> are supported on the platform P by lugs t<1>-t<2> and are coupled together by the toothed segment s<1> and toothed wheel s<2>. A motor m engages the wheel s<2> and causes the axes of the auxiliary gyros to tilt transversely through an angle alpha, depending on the speed of the ship so that their reaction to the forced movement just balances the distributing forces on the system due to changes in the ship's speed. A similar apparatus to that shown in Fig. 2, but adapted to stabilize only about the ship's longitudinal axis is described.
