Title: An improved machine for removing footwear from lasts
IPC: C01C1/242
Filed: 1933-08-05
Abstract: 403,050. Boot-making machines. SCHON ET CIE AKT.-GES., Pirmasens, Germany. Aug. 5, 1933, No. 22104. Convention date, Dec. 30, 1932. [Class 17 (i).] Shoes, removing from lasts.-In a machine for removing shoes from lasts, hydraulic means is employed for both pressing the shoe on the last against a shoeremoving tool, and for removing the shoe. A gearwheel pump 3 delivers oil from the bottom of a casing 1 to a pressure pipe 6 communicating with a control valve 25 actuated by a treadle 32 and with a piston 13. This piston actuates an arm 20 carrying the last pin 21 adjacent to a rubber roll 10 which may be fluted or otherwise shaped to correspond to the heel end of the shoe. The roll is mounted on a piston 8 in a cylinder opening into the cylinder of the piston 13. The latter piston is provided with a coaxial sleeve 17 serving as a seat for a spring pressed ball valve 15 beyond which is a passage 13c opening into an annular recess 13b. At the other end of the piston is an annular recess 13a normally connecting the uppermost cylinder with an oil return passage 7c. The valve 25 has an annular recess 25a normally connecting the pressure pipe 6 with the return passage 7c this recess having an extension leading to an excess pressure relief valve comprising a bored seating 26, ball valve 27 and spring plunger 28. In operation, a lasted shoe is positioned on the last pin. The treadle is depressed moving the valve 25 which closes the oil return passage and causes the oil to press the shoe against the rubber roll. The valve 15 then yields, and oil flowing past it raises the piston 8 with the result that the heel end of the shoe is moved upwardly. Should the treadle be inadvertently kept depressed, a return pipe 37 limits the ascent of the piston 8. Release of the treadle allows all parts to return to starting position.

Title: Radio beacon
IPC: G01S1/02
Filed: 1944-11-10
Abstract: 586,814. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. Nov. 10, 1944, No. 22161. Convention date, Nov. 15, 1943. [Class 40 (v)] . In a radio beacon, a carrier-frequency radiation pattern 60 having minimum (not zero) radiation in a given direction is combined with a. sideband radiation pattern 70 arranged with its maximum radiation in the same direction, the sideband maximum being smaller than the carrier minimum, and 'the two patterns being periodically switched (to 61, 71). When the signals are used in conjunction with a receiver having A.V.C., a very sharp course indication can be obtained with a two-antenna beacon array. As the carrier need never be 100 per cent modulated, voice signals may be used to modulate the carrier if desired, providing the voice signal modulation does not increase the total modulation to more than 100 per cent in any direction. Fig. 2 shows a beacon using only two antennas 36, 37 to which carrier signals from source 30 and sideband signals from a balanced modulator 40 are fed via balanced bridges 34, 35. Keyed switches 32, 41 introduce into the shorter feeders an extra length of line giving a phase shift equal to twice the difference of the antenna phasing, thus reversing the radiation pattern. The phase shifter 39 is provided to adjust the phase of the-suppressed carrier of the'sideband radiation to be substantially the same as that of the carrier radiation on the course line, in order to reduce distortion at the receiver. Arrangements using separate antenna arrays for carrier and sideband radiation, Fig. 1 (not shown), and a 5-antenna array, Fig. 5 (not shown) are also described.
