Title: Improvements in and connected with automatic car couplings for railway and like vehicles
IPC: B61G3/04
Filed: 1928-05-22
Abstract: 317,543. Stone & Co., Ltd., J., (Richards, TW. F.). May 22, 1928. Couplings, automatic. - In an automatic, knuckle coupling for railway &c. vehicles of the kind in which a locking block e, Fig. 1, is adapted in an intermediate or lock-set position to take a seating on a ledge b<1> on the coupler-head and to be removed therefrom by the tail of the knuckle c during the opening movement of the latter, the lock e is connected by a toggle linkage to a transverse shaft m, Fig. 11, so that operation of the coupling may be effected from the side of the vehicle. In the toggle linkage employed one link g is preferably connected as shown to the lock e and the other link h to a spindle j having an eye j', Fig. 5, engaged by the inner end of the shaft m. In the lowermost or locking position, Fig. 1, of the lock e the link h rests on a shoulder l on the coupler-head, and a leg or extension e<1> of the lock e rests on a step h<1> on the link h. Elevation of the lock e above the lock-set position is arranged in known manner to actuate a knucklethrowing lever o, Fig. 5, which co-operates with the toggle g, h to give a substantially uniform mechanical advantage throughout the range of the opening movement of the knuckle. In order to facilitate coupling with an opposing vehicle the shank b, Fig. 11, of the coupler-head is preferably pivoted at u to the draw-bar t, and the shaft m is adapted to slide transversely in addition to rotating in a bracket n on the vehicle. The shaft is disposed at a slight inclination to the transverse axis of the vehicle and the end or handle portion w<1> is normally arranged out of the vertical whereby the weight of the handle portion tends to rotate the shaft m and, by urging the block e towards its lowermost position, prevents rising of the latter and consequent accidental uncoupling.

Title: Method for producing thermo-electric modules having a high energy density and thermo-electirc modules produced according to that method
IPC: H01L35/34
Filed: 1973-03-29
Abstract: 1369403 Peltier units COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 29 March 1973 [30 March 1972] 15142/73 Heading H1K A sheet of alternately arranged P- and N-type thermoelectric elements 3-8 held together by epoxy resin 16 is produced with the requisite thinness by slicing a larger block. Because of the small lateral spacing of the elements, the bridges 9 and their application are special to avoid the risk of short-circuiting adjacent units by solder spread during bonding. All the bridges shown are short sections of cylindrical rod (with their ends cut to show ellipsoidal faces); the direct area of contact between a bridge and its limbs is therefore small and, after the application of molten solder to the limbs, bedding the bridges in the still molten solder does not result in appreciable solder spread. The Peltier unit described is mounted at the junction of the two heat pipes 1 and 2 to effect heat transfer between them. If the wicks (not shown) of the heat pipes are non-conductive they may rest on the bridges which may be provided with channels to receive the wicks and give better liquid transfer. Several rectangular arrays may be mounted side by side in a single heat transfer wall.

Abstract: 621,473. Automatic control systems for aircraft. SMITH & SONS (ENGLAND), Ltd., S., and MEREDITH, F. W. June 15, 1945, Nos. 15334/45 and 17663/46. [Class 38 (iv)] In an automatic control system a condition is controlled in correspondence with both a measured quantity and its rate of change to a value proportional to the difference between the transient integral of the condition and the measured quantity. As shown, Fig. 1, control of an aircraft elevators is effected to cause the aircraft to be brought smoothly into a radio beam. The difference between the rate-ofpitch-signal generated by the pitch gyroscope 8 and the rate-of-elevated-displacement signal produced by generator 22 is applied to the high gain amplifier 21, which operates the motor 19. The latter drives the elevators 9 through gearing 18, and also drives the generator 22. In addition, the output signal of pitch gyro 8, which has the frequency of the aircraft supply, is fed to circuit 1 where it is demodulated and a transient integral of the signal is produced. Circuit 2 produces a D.C. voltage proportional to the vertical distance of the aircraft from the beam and the difference between the outputs from circuits 1, 2 is supplied to circuit 3 where it is re-modulated and introduced into the input of the amplifier 21 in series with the signals from gyroscope 8 and generator 22, to stabilize the aircraft and cause it to subside on to the beam in pitch. The pitch pendulum 10 is short-circuited to prevent departure from level flight. Similarly, the aircraft may be controlled in yaw and roll. To effect damping of the short period motion of the aircraft, the pitch gyroscope signal is applied to a thermionic circuit, Fig. 5 (not shown), the subject of Specification 654,048. Specification 611,037, [Group XXXV], is referred to.

Filed: 1926-06-21
Abstract: 253,943. Huguet d'Amour, P. G. June 20, 1925, [Convention date]. Diarphragms.-A diaphragm for sound recording or reproducing apparatus is formed by securing a piece of fabric &c., preferably at its centre, by a threaded rod D, cap E or nut F to a board A, the fabric then being stretched and its edges secured to a frame C supported on posts B on the board A. A diaphragm approximating to the shape shown in dotted lines is thus obtained. After stretching the fabric is coated on one or both sides with varnish &c. The diaphragm may then be detached and employed either by itself or with its edges mounted upon a suitable support, the actuating means being connected to its centre. Instead of dismounting the diaphragm, the frame C may be employed as the supporting means, in which case the posts B are replaced by boards forming a box or case, and the edges of the diaphragm are covered with a framing.
