Title: Improvements in or relating to Superstructures on the Open Decks of Power-driven Ships.
Inventor: MACK ROBERT FREDERICK
IPC: B63G13/02
Filed: 1917-05-17
Abstract: 111,633. Mack, R. F. May 17, 1917. Resistance to propulsion, reducing; smoke, discharging; invisible, rerdering. - The superstructures on the open decks of power-driven ships are arranged so as to render the ships less visible to the enemy and to reduce wind resistance to a minimum. The masts are made up of light steel telescopic parts 1, 2, 3, operated rapidly by hydraulic pistons 7 connected by rods 6 to the top of each mast. The smoke is discharged through casings 12, 13 extending horizontally above the deck so as to form a smoke screen. The deck housings 10 are made low and V-shaped towards the bow to reduce aerial resistance.

IPC: F04B49/08
Filed: 1957-03-04
Abstract: 841,286. Reciprocating pumps. POPE, J. A., and ROLLS-ROYCE Ltd. March 3, 1958 [March 4, 1957], No. 7179/57. Class 102(1). A reciprocating pump comprises a plunger 30, reciprocated by an eccentric 14 in a cylinder 20, which delivers after the plunger has closed the inlet ports 24. The cylinder 20 is slidable in the pump body 17 and bears against a member 28 adjustably mounted in the body 17 such that axial movement of the member 28 causes axial movement of the cylinder and hence the position during the stroke at which the plunger closes the inlet ports 24. The cylinder may bear against the member 28 either due to the pressure in the cylinder or by a lock nut 29 screwed to the outlet 23 which is attached to the cylinder. Stops 34 are provided to limit the movement of the cylinder in one direction. Two pumps may be mounted on opposite sides of a driving shaft carrying two eccentrics. Specification 840,506 is referred to.

Title: Apparatus for representing electrically the value of a function of a variable
IPC: G06G7/26
Filed: 1941-06-13
Abstract: 621,835. Electrical calculating-apparatus. CONTRAVES AKT.-GES. June 13, 1941, No. 7531. Convention date, June 15, 1940. [Class 106 (i)] [Also in Group XXXVIII] Apparatus for determining the value of a function of a variable, using for the purpose coarse and fine stages is characterised by a common drive for the two stages, and the insertion between the two stages of a control device which, simultaneously with the continuous drive of the fine stage, adjusts the coarse stage step-by-step, in such a manner that the equivalent value in the fine stage is automatically cancelled. As shown in Fig. 2, the value x of which a function is to be obtained is entered into a network by turning a wheel 6 which rotates brushes 9, 9a over a series of contacts 8 connected to circular resistances. The wheel 6 also drives shafts 15, 19 to move a slide 33 through a screw 34 and to rotate eccentrics 27 to reciprocate a casing 20 in which two sets of spring-pressed pawls 21 act on a disc 30 connected by a rod 29 to a link 31 pivoted to a rod 39 acted on by springs 40, 41 connected to the slide 33. The rod 39 also carries a bar 46 moving brushes 47, 48 over contacts 49, 50 connected to resistances in a coarse-adjustment stage. When the wheel 6 is turned until the brushes 9 or 9a reach the regions u<SP>1</SP> or u <SP>2</SP>, the casing 20 moves sufficiently for the disc 30 to be released by one pawl and engaged with the next, under the pull or push of the slide 33, whereupon the rod 39 is restored to a central position and the brushes 47, 48 are moved quickly, upwards or downwards, to the adjacent contacts 49, 50 to compensate for the change of the fine adjustment. The contacts 50 are connected alternately to the brushes 9, 9a, the operative circuit being shown in heavy lines. The circuit in Fig. 2 is used for evaluating an expression y=A (n.xg+m.xf), the circuits 3, 4 entering the first and second parts, respectively. The circuit is fed by a decoupling 6-pole network 1 and the value y is taken from an additive 6-pole network 2. In the case of a function involving multiplicative as well as additive connections, Fig. 3, the fine adjustments of the 4-pole networks 3, 4 may be effected directly by a wheel 1 while the compensating coarse adjustment of the networks 5, 6 may be effected simultaneously through a device 2 of the kind already described. Specification 520,228 is referred to.
