Title: Improvements in internal combustion engines with compression ignition
IPC: F02B3/06
Filed: 1938-04-13
Abstract: 505,713. Oil engines. KAMMER, G. S. April 13, 1938, No. 11419. [Class 7 (iii)] In a compression ignition engine having a combustion chamber separated from the cylinder space by closure valve elements or members, the valve members or elements are so moved as quickly to reduce the transfer cross-sectional area between the combustion chamber and the cylinder to zero or other minimum value shortly before the end of the compression stroke, and after the working piston has passed its inner dead centre gradually to increase the area to its maximum in such a manner that the cylinder pressure at any instant does not exceed a predetermined value, the maximum area. being retained until shortly before the end of the compression stroke. The transfer of combustion products from a separate combustion chamber 3 through a passage 10 to the working cylinder is controlled by a slide valve 5 actuated by a cam 13 which rapidly closes or almost. closes the valve near the end of the compression stroke, giving a minimum opening at the dead centre position, and then opens the passage gradually during the working stroke. The passage may be kept closed or almost closed during most of the compression stroke and then be opened suddenly, ready for the abovementioned closure, to produce turbulence in the chamber. To avoid excessive temperatures, the valve stem 17 may have a copper or silver insert and the insert may extend into the valve itself. In modifications, the slide valve 5 is replaced by an oscillating valve having a transverse port of constant cross-section or by a continuously rotating valve having a peripheral passage of varying width Corresponding to the form of the cam 13. In other forms, the combustion chamber 3 constitutes the valve and may have several spaced ports 8<1> ... 8<4>, Fig. 15, co-operating with corresponding ports 9<1> ... 9<4> formed in the valve casing and leading into an annular passage 30 which communicates with the passage 10 to the working cylinder. As shown in Fig. 17, the chamber 3 is formed with double walls to accommodate a cooling medium and the cooling insert 21 extends into the double walls, the chamber being rotated continuously to permit an opening 32 in or at the top of its walls to control the port 9 of the passage to the cylinder. When the combustion chamber is in the working piston, the passage is controlled by a piston moving parallel to the axis of the working piston and formed with a tapered end entering the passage or else by an oscillating valve 5, Fig. 21, having ports 12 co-operating with ports 8 in a stationary cylinder which obturates the passage.

[Also in Division F2] A guide for rods in a ring-peeling machine comprises three sets of balls 3, Fig. 1, supported in elongated cages (2), Fig. 2 (not shown), disposed at an angular spacing of 120 degrees in a worm-wheel 8, the latter having cam surfaces (9) for radially adjusting the cages, and a worm (10) meshing with the wheel, which is axially displaceable against springs (13). The cages are provided with end covers 6, and a pressure jaw 7, the covers and jaws being faced with hard metal. The cages are set to receive a rod of given cross-section by turning the worm wheel 8 by worm (10), so that cams (9) engage jaws 7. Any deviation in the crosssection of the rod causes the cages to move radially, which is possible due to the worm (10) moving axially.

Title: Antenna systems for radio receivers
IPC: H01Q1/46
Filed: 1948-04-28
Abstract: 656,853. Aerials. PHILCO CORPORATION. April 28, 1948, No. 11664. Convention date, May 1, 1947. [Class 40 (vii)] In a radio receiver which uses the mains lead as the aerial, the mains lead is arranged to present a low impedance to the receiver chassis to radio-frequency signals at its receiver end, and the radio-frequency input of the receiver is coupled to the lead at a point physically displaced from the low impedance point. As shown, the mains lead 21 passes through an aperture in the metallic chassis 4 and is coupled to the primary of the power-pack transformer. Condensers 15 and 16 are connected between opposite ends of the primary and earth to reduce the pick-up of spurious radio frequency energy through the power-supply circuits and also to provide the low impedance referred to above. The radio -frequency-amplifier stage of the receiver is coupled by lead 24 and condensers 22 and 23 to the separate conductors of the mains lead which function in parallel as a single aerial. The lead 24 is coupled to the lead 21 at a point between a quarter and an eighth wavelength at the operating frequency from the lowimpedance point. The greatest radio-frequency voltage is obtained at distances of a quarterwavelength, but it is found that optimum results are achieved when the impedance from the tapping point to the chassis matches the receiver input impedance. The condensers 22 and 23 may be chosen either so as to have negligible impedance or so as to resonate with the receiver input circuit. One of the condensers 22, 23 may be omitted if desired. Similarly one of the condensers 15, 16 may be omitted, or, if there is sufficient distributed capacity, both may be omitted. Fig. 2 shows an arrangement for coupling lead 24 to the mains lead 21, a metallic sleeve being fitted over the lead 21 and soldered or otherwise secured to the lead 24. In an alternative arrangement, Fig. 3 (not shown), the mains lead includes a third conductor to which the lead 24 is conductively connected at a point between an eighth and a quarter wavelength from the low-impedance point in the receiver. The third conductor may be conductively connected to the chassis of the receiver adjacent the aperture through which the mains lead passes. Specification 340,389 is referred to.
