Filed: 1930-05-16
Abstract: 352,634. Hay sweeps &c. HOSKEN, TREVITHICK, POLKINHORN, & CO., Ltd., Princes House, and ROSEWARNE, J. N., Tremont, both in Truro, Cornwall. May 16, 1930, No. 15114. [Class 6 (iii).] A hay sweep or like device is fitted with means enabling the point of application of the draught to the implement to be varied so that the implement may be used with or without leverage tending to hold the points of the collecting members to the ground or with a variable amount of such leverage. Teeth 2 are fixed to the main beam 1 of the implement which is provided with handles 3 having struts 5. When tripped the implement rolls over the curved parts of the handles 3 and is assisted back to normal position by the engagement of sprags 6 with the ground. The draught attachment is made to vertical members 7 arranged at the ends of the main beam 1 and provided with holes to take the draught-hooks, such holes being provided at the top ends of the members for use when leverage is wanted and at the bottom in line with the beam, when leverage is not required. In a modification each member 7 may be made in two pieces the one, provided with the opening for the draughthook, adjustable upon the other so that the leverage may be varied. In a further modification the machine may be altered from working with leverage to working without leverage during its normal use. The draught-hook 24 passes through a hole 9 in the member 7 which is pivoted to the beam 1 and is held in vertical position by a spring-pressed hook 17 engaging over a stop 18. A cord 20, that may be pulled by the attendant, actuates a tripping lever 19 and so releases the hock 15 permitting the member 7 to take up the " no-leverage " position. The draught-hook 24 has a long rigid shank 8 formed with an eye 25 to which the draught-chain 22 is attached, as shown in Fig. 2. Shoes, which may be pivoted and provided with bolts for adjusting their depth, are fitted at the rear ends of some of the teeth 2.

A bus-bar arrangement comprises a span 11, in which at one end the bus-bar is held rigidly with its longitudinal axis horizontal by insulator 10a and at the other end the bus-bar is supported freely at the top of insulator 10b by a flexible joint 12 at a height above the fixed end, preferably at least two fifths of the sag which would occur if both ends were free. With this arrangement there is no horizontal load and substantially no bending moment to the bus-bar at the supports. On a horizontal site this difference in height should correspond to not more than 31/5 times the normal sag which would be produced if both supports were at the same height and freely supported and preferably should be equal thereto, in order that the maximum bending moment acting on the bar as the supports is reduced. On a sloping site, Fig. 3, similar arrangements are employed, but where it is not possible to ensure that an' insulator 30c is lower than its neighbour 30b, the bus-bar 33 of the next span is increased to include a joint 35 which is flexible during assembly but is clamped to become rigid when construction is complete.

Abstract: 783,213. Waveguides. SPERRY CORPORATION. June 1, 1955, No. 15767/55. Class 40 (8). [Also in Group XL (c)] In a waveguide transmission system one collinear arm 28 of a magic T-junction 20 is short-circuited at its end and the other collinear arm is open ended but closed intermittently by the blades 36 of a rotary shutter wheel, so that a wave transmitted from the shunt arm 30 to the series arm 32 is intermittently interrupted due to the alternate match and mismatch. Two magic T's may be connected as shown to a radio-frequency source connected to an E-plane input waveguide 38 so that the open-ended collinear arms 26 are respectively opened and closed alternately by different blades of the rotary wheel and so that the energy reflected at the T-junction 29 which has both collinear arms 26, 28 short-circuited is in exact phase with the energy supplied along the other shunt waveguide 30 from the input guide 38. The openended arms 26 may be closed by a diaphragm 40 having a resonant slot 42 to decrease the changeover time from opento short-circuit. Moreover, to further shorten the changeover time, each collinear arm 26, 28 may include a passive network comprising a window 43 with inductive iris and a tuning probe 46 between the windows 43 and ends of the arms 26, 28. Finally, to provide more nearly infinite impedance at the ends of the arms 26 when the slots 42 are open, the arms 26 may be extended by shorted stubs 48 just over a quarter wavelength long, to allow for the passive network, the wheel 36 entering between flanges 52, 54 on the arm 26 and stub preventing escape of energy, this also being assisted by an annular quarter-wave choke 56 in the stub flange.
