Title: Method of storage and transportation of perishable articles
IPC: A23B7/148
Filed: 1924-05-06
Abstract: 240,507. Thompson, J. M. May 6, 1924. Ventilating ships; forced ventilation; ventilating-pipes, arrangements and adaptations of.-Relates to a method of storing and transporting vegetable produce, more particularly in ships' holds, whereby damage to the produce from fungal and other diseases is prevented, and consists in controlling the flow of a slow and uniform downward current of air through the body of the produce so as to prevent undue accumulation of carbon dioxide, deposit of liquid water, and undue rise of temperature, but without excessive drying of the produce, and also to ensure such a percentage of carbon dioxide remaining as to maintain a state of reduced respiration in which further ripening is arrested. The apparatus is shown as fitted in a ship. Air is admitted through the pipe 1 and passes through collecting chambers 2, 3 to perforated distribution pipes 4 at the top of the hold. After passing through the produce, the air is led away through perforated pipes 6, arranged beneath a perforated false floor 5 and communicating by a common main 7 with a third collecting chamber 8, fan 9, and outlet pipe 10. Manometers 11 and valves 12 are provided in the main 7. The entering air may be dried and slightly heated, if desired. Examples are given of values for the rate of flow of the air, average temperature, humidity and maximum carbon dioxide content in the hold for ripe and unripe oranges, and other fruit and vegetables. If oranges are highly infected, the fungi is destroyed by raising the carbon dioxide content for a short period to 20 per cent or over, or 0.01 per cent of carbon tetrachloride may be introduced. Specifications 20203/93, [Class 116, Shop &c. accessories], and 12920/03, [Class 49, Food &c.], are referred to.

Title: Improvements in and relating to change speed gearing
IPC: F16H61/02
Filed: 1948-04-26
Abstract: 646,094. Facilitating speed-change. WEBSTER & BENNETT, Ltd., and BENNETT, D. W. April 26, 1948, No. 11365. [Class 80(ii)] A pneumatic, hydraulic or electric inching device, for imparting a slow oscillatory movement to the main input shaft c of a sliding - gear or clutch change-speed gear during a manual or power shift. whilst the main clutch is disengaged, to facilitate gear engagement, is controlled by the sliding gear members b, Fig. 3, so that the device functions only when one or more are not in correct mesh. In the hydraulic control shown the input shaft c is slowly oscillated by a reciprocating piston o, Fig. 4, having rack-and-pinion engagement m, with a disc h which is frictionally or positively clutched to the input shaft c by pressure applied to the right face of a piston g, Fig. 3, in opposition to pressure acting constantly on its stepped left face. Movement of any one or more of the sliding-gears b, Fig. 3, from its engaged position closes a corresponding one of a group of valves t arranged in series in a pipe-line w, thus cutting off pressure-supply from an inletx through the line w to the lower face of a piston-valve 5, Fig. 2 which then moves downwards u n d e r load of a spring or, as shown, of pressure act in g constantly through an inlet 7 or the upper face of a push-piece 26 of lesser diameter. This downward valve movement cuts off a pressure inlet 8 and  exhausts at 32 the line 9 of the main hydraulically-actuated clutch (not shown), which then disengages. At the same time the valve 5 shuts off an exhaust-port 27 from, and pressurizes, from the inlet 7 through a passage 28, a line 11 leading to the right face of the inching-clutch piston g, Fig. 3, which then engages. Movement of the valve 5, Fig. 2, also opens the pressure-inlet passage 28 to a passage 29 opening to a reversing-valve 6, which initially feeds pressure through a line 17 to the left inlet r, Fig. 4, of the inching-piston o, which then makes a stroke to the right, inching the input shaft c, at the completion of which it operates a change-over valve 22 which changes the feed-connection of a pressure-inlet 23 from a line 19 leading to the upper face of the reversing-valve 6, Fig. 2, to a line 20 leading to its lower face, whereby the reversing-valve 6 moves up to exhaust the line 19 and pressurize the line 20 leading to the right inlet s of the inching-piston o. The latter then makes a return stroke to the left, operating the change-over valve 22, to continue the reciprocating sequence until completion of mesh of the desired gear causes the valves t again to open the pressure-line w, which returns to the piston-valve 5, Fig. 2, to its upper portion exhausting the inching- piston and inching-clutch lines 29, 11, and again feeding the main-clutch line 9 to resume drive in the new ratio. According to the Provisional Specification the rackpiston o may turn the shaft through a oneway clutch to impart stepwise angular movement thereto in one direction only.

Abstract: 1,260,991. Pneumatic dashpots. " COQ " N.V. 12 March, 1970 [14 March, 1969], No. 11916/70. Heading F2S. [Also in Divisions F1 and H1] The movement of a member such as a rod 3 operating an electric switch (not shown) is damped by attaching to it a piston 11 which, at least at the end of a predetermined range of movement of the member, enters a cylinder 9 from which gas is expelled through a non-return valve 19 which is biased by a gas cushion 36. In the case of electric circuit breaker operation, the whole assembly may be in an atmosphere of SF 6  to prevent arcing of the switch contacts, and the SF 6  also serves as the damping medium. In Fig. 1, an operating piston 2 in a cylinder 1 is acted on by gas from a source 30 under the control of valves 28, 29 to move from one end to the other of the cylinder. The operating piston carries two damping pistons 10, 11 which, in combination with respective cylinders 8, 9 effectively act as end stops for the operating piston. Each of these end stops constitutes a pneumatic damper in which a respective non- return valve 18 or 19 opens to allow gas to escape whenever the cylinder pressure exceeds a predetermined value. The value of this predetermined pressure depends on the pressure of the gas cushion and the latter should therefore be adjustable to allow for different operating pressure values. As shown it is self-adjusting, since the gas cushion and the main cylinder both receive pressure from the same source 30, so that the operating pressure and the biasing pressure are maintained in an appropriate relationship. Figs. 2 and 3 (not shown) depict modifications of Fig. 1 in which the floating piston 33 bounding the gas cushion is replaced by a diaphragm or bellows. In Fig. 1, but not in Figs. 2 and 3, the biasing force due to gas pressure is augmented by the bias of a spring 17.
