Compressed air or gas is admitted through port 22<SP>1</SP> into chamber 24<SP>1</SP> and passes through ports 40<SP>1</SP> into cylinder 10 causing piston 16 to move to the left. Air present in the cylinder 10 to the left of piston 16 is exhausted through ports 40 and 24 until the piston 16 engages valve 34 which is moved to the left against the action of spring 44. When ports 40 are closed by collar 26, the air is compressed between head 12 and piston 16 and bleeds through passage 60, past an adjustment screw 62 into chamber 40 thereby cushioning the piston motion until valve 34 bottoms against head 12. When compressed air is admitted through port 22, a spring-loaded valve 50 is unseated and air passes through passage 46, and groove 58 into cylinder 10 causing piston 16 to move to the right. When valve 34 moves to the right to uncover ports 40, valve 50 is reseated. At the other cylinder end passages 72, 74 and valve 76 function similarly to passage 46 groove 58 and valve 50, and a bleed passage (not shown) is provided in head 14. In a modification ports 40 are replaced by grooves on valve 34.

Filed: 1928-08-03
Abstract: 303,098. Ruth-Aldo Co., Inc., (Assignees of Barthelemy, H. L.). Dec. 28, 1927, [Convention date]. Cellulose carboxylates.-The usual saponification of primary cellulose acetates and mixed acetic esters of cellulose is carried out with the aid of hydrochloric and hydrofluoric acids. In an example there is added to the primary acetylation solution so much aqueous acetic or formic acid as will decompose the remaining acetic anhydride without producing any flocculation in the solution; the latter is then cooled; to the cooled solution there is added a further quantity of aqueous acetic or formic acid containing an amount of hydrochloric and hydrofluoric acids, which is at least chemically equivalent to the amount of sulphuric acid used as catalyst, the quantity of water added being adjusted to be equal to 5-15 per cent of the organic acids present; during this second stage the reaction may be accelerated by slightly raising the temperature. Operating in this manner there are obtained on precipitation partly saponified acetates free from sulphuric acid esters and also lime salts and silica.

Title: Magnetic shift register
Inventor: UNDERHILL MICHAEL JAMES
IPC: G11C19/06
Filed: 1963-06-06
Abstract: 1,039,026. Circuits employing bi-stable magnetic elements. MULLARD Ltd. June 4, 1964 [June 6, 1963], No. 22550/63. Heading H3B. In a shift register comprising a plurality of bi-stable magnetic cores the drive pulses are of alternately opposite polarity so that as information is fed into one core any information stored in that core is simultaneously driven into the next successive core. In the register of Fig. 1 comprising cores 1, 2, drive pulses consisting of fast rising alternately polarized pulses 9, Fig. 2 (not shown), superimposed on an A.C. prime current 10 are supplied to common drive/prime winding 5, the prime current having an amplitude insufficient to switch flux around the main aperture. Fig. 6 (a) to (j) shows a bit sequence of 1100 being driven through two consecutive cores of a shift register, the arrows representing the direction of flux in the cores. Initially the cores are in the " 0 " state, Fig. 6 (a), and after priming a positive drive pulse switches the flux in core 1 to store a " 1 " but has no effect on core 2, Fig. 6 (b). The prime current just prior to the next negative drive pulse reverses the flux round hole 4 in core 2 but does not unblock core 1, Fig. 6 (c), so that the next negative drive pulse switches flux in the output ring of core 1 and transfers a " 1 " to core 2 and at the same time reads a " 1 " into the core 1, Fig. 6 (d). Priming in the positive direction, Fig. 6 (e) has no effect on the direction of the fluxes but the positive drive pulse drives flux out of both cores transferring " 1's " from 1 to 2 and out of 2, there being no flux charge in the input ring of 1, Fig. 6 (f). Priming and driving in the following positive direction clears core 2 to the " 0 " state, Figs. 6 (g), (h), and priming then returns both cores to state shown in Fig. 6(a). The transfluxors may be connected in a ring. In the modification of Figs. 7, 8, transfluxors having two minor apertures may be employed, apertures 27, 28 forming the same function as cores 7, 8 of Fig. 1, acting as threshold devices so that stable flux transfer takes place. Also separate prime 29 and drive 26 windings are employed, the prime pulses starting after the drive pulse. More than one output winding may be employed to feed a plurality of further devices.
