Title: Infinitely variable cone pulley transmission
IPC: F16H63/06
Filed: 1971-04-23
Abstract: 1325634 Expanding wheel gear REIMERS GETRIEBE AG 23 April 1971 [24 April 1970] 10999/71 Heading F2D In an expanding pulley belt or chain gear in which one (e.g. the output or input) pulley is spring-loaded whilst the other (input or output) 2, 3, is loaded hydraulically, with automatic and manual control, an hydraulic piston and cylinder assembly 5, 6 is carried by the pulley shaft 1; the hydraulic pump 15 is concentric with the shaft and directly driven thereby through a toothed coupling 12, and a control valve 22 is carried in the pump housing 11, attached to the transmission housing 8, so that the entire hydraulic assembly forms a unit with the pulley and no external conduits or pump drive are required. The movable pulley flange 2 is loaded towards the axially fixed flange 3 by an initial loading spring 7 and by hydraulic pressure supplied to the cylinder space 41 through bores in the shaft 1 and pump shaft 9 from an end chamber 18, fed directly by the pump 15, pressure being controlled by variably exhausting the chamber 18 through a port 25 of the control valve 22, co-operating with an exhaust groove 26, leading, through a passage 28, including a fixed restrictor (40, Fig. 5, not shown), to a reservoir in the transmission housing from which the pump receives its supply through an inlet passage 15. In operation, movement of the pulley flange 2, e.g. to the right, under torque change, through a central rod 29 and lever 31, shifts the control valve 22 left, against a return spring 32, increasing the exhaust communication 25, 26, which reduces pressure in the chambers 18, 41, permitting the pulley flange 2 to be moved left by belt tension to restore balance between the expanding force of the belt and the clamping pressure. The fulcrum 34 of the lever 31 is eccentrically adjustable by a manual lever 35, for manual ratio control. A spring-loaded pressure relief valve 38 (Fig. 5, not shown) is provided for the pressure space 18, and in Fig. 6, not shown, is combined with a coned control valve (42).

Boiling-pans and the like.-A tubular heating-apparatus for use with vacuum and like pans comprises a series of tubes 4 connected to two headers 5, 5<1> in the bottom of the pan or vessel 1, the heating-fluid being caused to circulate to and fro between the headers by the tubes both on the right and left hand sides bv means of partitions 7 arranged in the headers. The tubes 4 are preferably segmental in shape, the inner ones extending through a semicircle, and the outer ones through a quarter of a circle, being connected to the headers at one end and to an intermediate divided socket-fitting 9 at the other end. The headers are formed in halves bolted together, and are supported in the pan at one point by the connexion between the inlet header 5 and the inside of the pan, and at other points by means of pivoted suspension links 10 which allow for expansion of the tubes. In the construction shown, the heating-fluid is admitted to the header 5 through an inlet 6 and passes by means of the four uppermost tubes on each side to the header 5<1>, thence by the next four lower tubes back to the inlet header, and so on, finally passing to the outlet 8. Drainage apertures 12 are formed in the partitions 7 so as to conduct condensed waterto the outlet 8.

Class 40(7) In a moving target indicating pulse radar system echo radio frequencies F and F+F D , where F is the transmitted frequency and F D  is the Doppler beat frequency from a moving target, are translated by mixing means which include an input from the transmitter oscillator into frequencies Fi and Fi+FD (where Fi is a fixed frequency) which are multiplied to give frequencies mFi and m (Fi+FD) and from these there is subtracted a locally-generated frequency (m-1) Fi to obtain frequencies Fi and m F D , and means separate out the latter frequency for moving target indication. In the first embodiment the transmitted frequency F obtains from a single oscillator and the receiver first local oscillator is a stable oscillator of frequency Fi, Fig. 1 (not shown). In a modification the transmitted frequency is compounded using a stable oscillator of frequency Fi, Fig. 2 (not shown). The frequency Fi is rejected by a discriminator consisting of a length of hollow rectangular waveguide shunted by a coaxial cable and the final output at frequency Fi+mF D  is detected and intensity modulates a cathode-ray tube beam. r applications of the Doppler beat frequency enhancement may be used to give a final frequency of Fi+(m)r.F<SP>D</SP> Reference has been directed by the Comptroller to Specification 605,454.

[Also in Division H4] In a system in which speed control signals are transmitted to a railway vehicle each control word is formed of binary digits which frequency-shift-key a carrier frequency. The phase angle of the carrier at the beginning of a bit is 180 degrees relative to that at the end of the preceding bit. Receiver, Fig. 2.-The received signals consist of a series of 6-bit words each selected from a comma-free code and representing a required speed. One such word is shown in Fig. 1 C as received. After filtering and limiting the signals pass to filters 14, 16 which select the respective shift frequencies, their outputs being as D, E. These signals are detected at 18, 20 and the resultant signals F, G feed a clock signal recovery circuit 24, 26, 28, in which circuit 24 produces signal H, and feed a difference amplifier 22 whose output passes to shift register 30. The register feeds a decoding unit which controls the vehicle's speed. In a second embodiment, Fig. 4 (not shown), the signals received from the track circuit pass via filter and limiter circuits which select the strongest signal of a number of frequency-shifted carriers, the weaker signals being assumed to relate to other track circuits. The register's parallel output feeds a group of gates, the coding of the received signal being such that for any one repeatedly received 6-bit word only one gate will respond, its output having a 1: 5 M: S ratio. The gates' outputs are filtered and passed to a speed control unit (not described) and to an OR gate which operates an emergency stop relay if there are simultaneous outputs from more than one filter.
