Abstract: 307,206. Mitchell, J., and Meboe, Ltd. Pistons; packing.-In a piston for a horizontal engine in which the packing-ring c, Fig. 1, is formed with flanges h engaging grooves j in the piston, inward movement of the packing is prevented at the lower part, to; take the weight of the piston. For this purpose either the ring c is formed with eccentric inner and outer peripheries or the grooves j have eccentric walls. The flanges h may be replaced by projections engaging recesses in the piston. Rotation of the packing is prevented by a stop on the piston engaging a recess in the packing-ring. In a modification flanges h, Fig. 11, on the piston engage grooves in the packing-ring c. Two packing- rings c<1>, c<2>, Fig. 6, may be separated by a solid ring s, the flange h on the packing-rings engaging flanges on the ring s and on solid rings s<1>, s<2>, or on the piston. Rotation may be prevented by engaging stops and recesses. The piston may comprise parts a, b, Fig. 1, engaging by flanges forming bayonet joints. The engaging surfaces may be inclined in order to draw the piston parts together. Alternatively the bayonet joints may comprise dovetail flanges engaging recesses, Fig. 12. Specification 250,296 is referred to.

IPC: F16C33/46
Filed: 1963-12-12
Abstract: 1,057,628. Making retainers for roller bearings; punching. TORRINGTON CO. Dec. 12, 1963 [Dec. 19, 1962], No. 6928/66. Divided out of 1,057,627. Headings B3A and B3W. A method of forming a bearing retainer having shaped windows therein for receiving and retaining rollers or needles comprises forming each said window in two distinct punching operations in a generally cylindrical retainer body, the one punching operation in the formation of each of the windows being effected simultaneously with the other punching operation in the formation of another of said windows. The sides 24 and 25, Fig. 9 (not shown), of the windows are formed of centre sections 26 and 28 and end sections 27 and 29. In the side 24 which is formed by the centre section 26 and end sections 27, the plane of the centre-section is disposed at an angle to a radial plane passing generally through the wall 24 and the plane of the end sections 27 is disposed at an equal angle on the opposite side of the radial plane. The planes of the sections 26 and 27 intersect in the thickness of the retainer body 18, Figs. 11 and 12 (not shown). The side 25 is similarly formed of a centre section 28 and end sections 29. Fig. 1 shows a punch 32 which has two cutting edges 37 and 38, each of which partially forms the window. In a first operation, Figs. 3 and 5 (not shown), the punch forms a partly finished window 30 in which the end sections 27 and the centre section 28 are completely machined, and the centre section 33 and the end sections 34 require further machining. A similarly partly finished window 31, symmetrical with the window 30 is formed by the cutting edge 38 of the punch. The retainer is then indexed round an amount equal to the pitch of the windows and the second punching operation is performed. The cutting edge 37 forms a further partly finished window similar to the window 30 and the cutting edge 38 finishmachines the centre section 33 and the end sections 34 of the first-formed window 30. Step-by-step rotation of the retainer continues until all the windows are formed and finished.

Filed: 1928-03-09
Abstract: 319,193. Armstrong, J. J. V., (Telefunken Ges. f³r Drahtlose Telegraphie). March 9, 1928. Automatic exchange systems.-Substations 7 on an automatic exchange 6 and the subscribers of a high-frequency system working on a common wave-length and calling each other selectively by means of number dials are interconnected through transfer apparatus 3 which converts high-frequency impulses into direct current impulses and vice versa. When a high-frequency subscriber calls the exchange 6, the rectified current from receiver E controls relay 27 which repeats impulses to the magnet 28 of a selector 30. The arm 30 is thus set to contact x operating relay 31 which completes a direct-current loop over conductors 8, 9. The impulses of succeeding digits are then repeated over this loop to control the exchange 6 in the usual manner. Earth impulsing instead of loop impulsing may be employed. When the subscriber 7 calls a high-frequency subscriber, contacts 23 complete a loop over conductors 10, 11 to operate relay 21 which starts up the transmitter S, and further impulses are repeated by relay 21 as interruptions in the emitted wave. In a modification, a single pair of conductors is used for connection in both directions, the switch-over at the transfer-apparatus being controlled by relay 31 whilst at the exchange 6 the conductors normally lead to a line relay controlling a line-switch but are switched over in the case of a call to the high-frequency system by a relay operated over the test wiper of the seizing connector. Reference has been directed by the Comptroller to Specification 267,151.
