Title: Improvements in milking devices
IPC: A01J5/08
Filed: 1963-02-06
Abstract: 978,384. Milking machines; teat cups. U.S. INDUSTRIES Inc. Feb. 6, 1963 [Feb. 21, 1962], No. 4882/63. Heading AIM. A teat cup shaped and proportioned to engage the teat of a cow in the immediate region of the sphincter muscle, comprises a cup 26 with connection 30 to a milk supply line and connection 32 to vacuum, and a resilient sleeve 33 shaped to provide an annular chamber 37 within cup 26 and an inner wall 38 to receive the teat. Passages 46 interconnect the chamber 37 and wall 38. Vacuum applied at 32 causes sleeve 33 to grip the teat and also to expand radially whereby the sphincter muscle is dilated allowing milk to flow from the teat. In a modification the sleeve 33 is shaped to provide a series of pockets in annular formation instead of a continuous wall 38. In the embodiment shown in Fig. 6, a number of suction elements 50 made e.g. of stainless steel and each having a dished central area 51 and peripheral flange 52 are connected by a wire 57 extending through tubular guides 56a. In use wire 57 is adjusted manually so that the elements 50 grip the teat firmly and suction is applied through vacuum lines 54, 55, opening of the teat canal being effected by sliding the wire 57 through the guides to expand the suction elements.

Title: Directive antenna system
IPC: H01Q19/13
Filed: 1949-02-25
Abstract: 663,924. Aerials. RADIO CORPORATION OF AMERICA. Feb. 25, 1949 [Feb. 27, 1948], No. 5201/49. Drawings to Specification. Class 40 (vii). A directive antenna system of the type including a radiator device in such position in front of a reflector that it partially intercepts the energy reflected therefrom, comprises means for radiating auxiliary energy from the radiator device in substantially the same direction as that from the reflector, to compensate for this shadow effect. The embodiment of Fig. 1 (not shown), comprises a " pill-box " reflector having energy fed thereto by a perpendicular wave-guide with a right angle bend near the open end and a narrow horizontal slit in the wall on the side away from the opening. The size of the slit is such that the amplitude of auxiliary radiation is equal to that of the masked radiation, and the phase is corrected by providing a dielectric body to cover the slit. Fig. 4 (not shown), illustrates the invention applied to a coaxial feeder where the central conductor projects into the reflector at its focus and is backed by a small semi-cylindrical reflector. In this case a slit is made in the small reflector and is again covered by a dielectric body to introduce the required phase delay. The invention is also applicable to the so-called " rear-feed " where a wave-guide extends through a reflector along the directive axis and has a cap at its open end to reflect energy back to the main reflector. In this case a small opening is made in the cap to radiate the same power as is intercepted by the device, Fig. 5 (not shown), and phasing is carried out either by a covering of dielectric as before or by designing the opening to act as a wave-guide near its cut-off frequency, thereby introducing a phase advance. A procedure for determination of optimum slit size and dielectric thickness is described in which the aerial system is used for reception on a secondary lobe and adjustments are made to give minimum response.
