Abstract: 709,383. Sewing-machines. GRITZNERKAYSER AKT.-GES. April 28, 1952 [April 27, 1951], No. 10677/52. Class 112 Feed by dogs. A feed-bar mechanism providing for variable height of the feeddog to suit the material being worked on (including lowering the dog that it is renreded ineffective) and for a substantially rectilinear feed movement of the dog comprises a swinging-block linkage formed by the feed-bar 8, a crank 10 on the feedadvance rock-shaft, and an arm 13 forming a toggle-mechanism with another arm 14, together with a beam-and-crank mechanism connected to the middle joint 15 of the toggle and arranged to maintain the toggle substantially straight during the feed movement and bent during the return movement of the feed-bar. In the embodiment shown the latter mechanism is constituted by an eccentric 7 on the looptaker shaft 6, which rotates clockwise, and the eccentric rod 23. The toggle link 14 is pivotally mounted at 16 eccentrically on a disc 18 which is carried by a horizontal spindle and is adjustable by a hand-lever 21 connected to an arm 18<1> on this spindle. With the lever 21 in an intermediate position the pivot pin 16 is in its highest position and the feed-dog 4 is correspondingly elevated; the eccentric is in the region of one dead-centre during feed of the work, keeping the toggle and the path of the dog practically straight, and the toggle is broken to lower the dog during the return stroke of the dog. Raising the lever 21 moves the disc 18 clockwise and lowers the pin 16 slightly, also moving it a little to the right; the path of the feed-dog is substantially unaffected in shape, but is slightly lowered in position. Lowering the lever 21 moves the pin 16 downwards to the left, causing the toggle to be broken and bringing the feed-dog below the level of the throat-plate surface so that it does not make contact with the work.

Title: Improvements in or relating to pulsed radar ranging, altimeter and like devices
IPC: G01S7/08
Filed: 1946-04-15
Abstract: 650,447. Radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 15, 1946, No. 11547. Convention date, Sept. 28, 1940. [Class 40 (vii)] A pulse radar system comprises two alternately operative oscillators, each of which, when operative, is used to generate a circular trace on the screen of a cathode-ray tube and to synchronize the transmission of exploring pulses, echo signals being displayed on the cathode-ray tube as radial deflections, so that, due to the persistence of vision, two concentric circular traces are seen simultaneously upon the screen, upon each of which are displayed the echo signals corresponding to the appropriate pulse transmission. In a radio altimeter, the vibrator 1 alternately keys the oscillators 3 and 5 which oscillate at frequencies f and <SP>3</SP>/ 10 f respectively. The output from oscillator 3 is frequency trebled in circuit 13, the output of which is applied together with the output from oscillator 5 to the amplifiers 19 and 21. The anode loads of the amplifiers are the tuned networks 23 and 25 which are so arranged that a concentric pair of circular traces is produced on the screen of the cathode-ray tube 43, one being produced from the oscillation of frequency 3f and one from the oscillation of frequency <SP>3</SP>/ 10 f. Alternate signals of frequency f and <SP>3</SP>/ 10 f are taken to the amplifier 46 and thence to synchronize a pulse generating circuit 55 which modulates the transmitter 57. As shown, signals are transmitted and received with the same aerial though separate aerials may be used. The output of the receiver 59 is applied to a radially deflecting electrode of the cathoderay tube. To protect the receiver during the pulse transmission an automatic-sensitivitycontrol circuit 61 is connected between the transmitter and receiver. Thus two time base traces are produced on the screen of the cathoderay tube, a main time base trace and an expanded trace which provides a fine reading scale. The invention is applicable to a combined altimeter and object locating system, Fig. 3 (not shown). The two alternately operative oscillators render two transmitters alternately operative to transmit exploring pulses at the repetition frequency of the corresponding oscillations, one transmitter transmits signals directed towards the earth for altimeter measurements, and the other transmits signals directed forward for objectlocating purposes. Separate R.F. receiving stages are provided for each transmitter, the I.F. stages being common. As before, the receiver output is used to produce radial deflections of the appropriate one of the two circular time bases.
