Title: Improvements in guards for dough brakes and like machines
IPC: A21C3/02
Filed: 1924-01-29
Abstract: 225,729. Grant, T. Jan. 29, 1924. Interconnecting guard with starting-gear.-In guard mechanism for machines having reversible rollers, a single guard, shiftable to either side of the rollers according to the direction of feed, is provided with means to prevent starting of the machine unless the guard has been fully moved into its appropriate protective position, whence it cannot be moved while the machine is running. As applied to a dough break of the kind described in Specification 101,994, rods C<3>, with or without wire netting or expanded metal, are mounted between end frames, each comprising a curved bar C' and inclined lateral bars C<4>, which extend from a plate C having a slot C<1> for the journal A<2> of the lower roller A<1>. A slotted plate C<5> retains the frame in position. Members B<3>, B<4> on the interconnected reversing-levers B', B<2> are shaped to co-operate with arcuate surfaces D', D<2> on the plate C, so that when the guard is in mid-position neither lever can be moved to start the machine, while, after the guard has been moved to the protective position on one side of the machine, as shown, the levers can be moved in the appropriate direction only, a member B<3> or B<4> then engaging under a shoulder D<3> or D<4> on the plate C to lock the guard. The guard, instead of being pivoted, may slide in guides at the end remote from the locking-gear, or at both ends. Where there is insufficient clearance between the rollers and the machine frame, the oscillating plate C may be situated elsewhere, as between the belt-shifting rods, and be linked to the guard.

Abstract: 701,984. Radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 3, 1952 [Jan. 31, 1951], No. 2470/51. Class 40 (7) A secondary radar system comprises a transmitter 1 radiating at least two C.W. frequencies (F1 and F2) a receiver, 3 and 4, associated therewith which is supplied with the transmitted frequencies each multiplied by a predetermined factor K by unit 2, a co-operating target having means 5, 6 and 7 for receiving the two radiated signals multiplying them in frequency by the same factor K, and re-radiating the multiplied frequencies, and at said receiver 3 and 4 means for mixing the directly applied multiplied frequencies with those received from the target to produce two doppler frequencies which after separation and amplification are phase-compared to give an indication of target range at 10. The frequencies received from the target are KF (1 Œ 2v/c) and KF2 (1 Œ 2v/c) where V is the radial velocity of the target and C the speed of light which give doppler frequencies on mixing respectively with KF1 and KF2 and KF1 2v/c and KF2 2v/c. The frequencies F1 and F2 must be chosen so that a phase difference of 360 degrees between these waves will be given at the extreme required range of the system if ambiguity is to be avoided. Alternatively use may be made of three or more original frequencies. The doppler frequencies obtained may be used in the usual way to determine the radial velocity of the target and means may be provided to cut out the frequency multipliers at the measuring station if it is desired to use the system as a primary radar for the detection of non- co-operating targets. The transmitter and receiver may be associated with non-directive aerials although if required for directional determination, directional transmitting and/or receiving aerials may be employed.

Abstract: 872,825. Locating conductive bodies. BREUKINK N.V., B. & G. Jan. 26, 1959 [Feb. 5, 1958], No. 2789/59. Class 37. A traffic detector for automatic or semiautomatic traffic signals comprises electrical conductors embedded in the road surface and connected with an oscillator so as to produce an electric field which extends above the road surface so that the passage of a vehicle disturbs the field to generate a signal for controlling the traffic signal. In the Figure shown a conventional oscillator 1, for example using an electron tube with a Hartley circuit, is associated with a conductor 3 which acts as a capacity and carries a proportion of the energy of the circuit in the form of electrostatic energy. The conductor is insulated with a coating 6 and embedded in the road surface 5 or in a block of insulating material itself embedded in the road surface. A further conductor 4 with insulating coating 7 is associated with a detector circuit 2 which may be of conventional design. The passage of a vehicle or of a pedestrian causes a disturbance of the electric field between conductor 3 and 4 so that a signal is produced at terminals 12, 13 which is connected with a control, not shown, of a traffic light. The modulation of the output from the oscillator caused by the passage of traffic may be reduced by the use of a filter in the detector circuit which has a limiting effect on the amplitude of the oscillations.

In a control arrangement for a steam turbine 3 driving a generator 4 the action of a device 1, responsive to the speed of the turbine rotor, which positions a steam inlet valve 7 is modified by adjustment of a linkage arrangement 8 in dependence on movement of a link by a device 2, responsive to the load on the generator, and movement of a balancing link by a device 5 responsive to the pressure in an intermediate steam superheater line. For an increase in load the tendency for rotor speed to fall and the consequent opening of the valve 7 by the device 1 is anticipated and enhanced by the device 2. When after a lag, due to the storage of steam in the superheater, the pressure sensed by the device 5 increases the valve to partially re-closed to the steady state position. In a modification, Fig. 2, (not shown), for use with a turbine having a pair of intermediate superheaters a linked arrangement of a pair of devices 5 is employed.
