Title: Equipment for measuring lengths or angles
IPC: G01D5/38
Filed: 1961-11-29
Abstract: 948, 680. Electric selective signalling systems. M. HENSOLDT & SOHNE OPTISCHE WERKE A. G. Nov. 29, 1961 [ Dec. 3, 1960; March 7, 1961; Sept. 30, 1961], No. 42590/61. Heading G4H. An incrementary displacement measuring system comprises a first displaceable scale carrying a plurality of spaced groups of uniform graduations and a second fixed uniformly graduated scale of sufficient length to bridge the gap between two groups of graduations on the displaceable scale whereby as the displaceable scale is moved past the fixed scale a corresponding train of electric pulses is produced by the two scales in conjunction with a suitable sensing device. Two main embodiments are described, photo-electric - using either detraction gratings or arrays of cylindrical lenses - and magnetic. In a first embodiment Fig. 1 a scale 3, shown in detail in Fig. 2, is moved past a fixed scale 7, and the arrangement is such that as the scale 2 moves the images of the groups of markings 4 migrate across the fixed scale 7, a new group of markings 4 moving on to the scale scale 7 just before the previous group moves off. A second embodiment Figs. 11, 12 is analogous to the first but uses magnetic sensing. In both embodiments 90-degree phase-shifted sensing is used to provide an indication of direction as well as extent of displacement. In a further photo-electric embodiment Fig. 14 both the displaceable scale 306 and the fixed scale 313 are formed of cylindrical lenses.

In the compression moulding of wedge or truncated wedge shapes, wherein non-fluent mixtures of granular material with tar and/or paraffin, e.g. tar dolomite refractory furnace linings, are compressed in a cavity defined between vertical opposed inclined face plungers within the parallel vertical sides of a die, the mould is filled in a vertical distribution corresponding to the shape of the inclined plunger faces by depositing the mixture thereinto from a filling member having the same size and shape as, and axially aligned with, the required distribution but having its opposed walls which are inclined to each other extending in a vertical plane. In a preferred arrangement a pair of adjacent cavities 9, 9<SP>1</SP> are simultaneously filled from a pair of filling members 8, 8<SP>1</SP> which are mounted in wheeled carriages 7, 7<SP>1</SP> for displacement along rails between a mould filling position and a position whereat they are filled from hoppers 4, 4<SP>1</SP> via a storage vessel 1 and a balance 2 and weighing vessels 3, 31. The members 8, 81 are open ended, with material being released therefrom into the cavities 9, 9<SP>1</SP> by downwardly opening flaps of the carriages 7, 7<SP>1</SP>. To facilitate the filling of different sized cavities 9, 9<SP>1</SP> the members 8, 8<SP>1</SP> are replaceably mounted in the carriages 8, 8<SP>1</SP>, and outlet frames 5, 5<SP>1</SP> of the hoppers 4, 4<SP>1</SP> are vertically adjustable. The material deposited from the hoppers 4, 4<SP>1</SP> is initially banked within the members 8, 8<SP>1</SP>, due to the inclined side walls thereof, but is distributed to an even height by the edges of the frames 5, 5<SP>1</SP> when the members 8, 8<SP>1</SP> are displaced with respect thereto. In the alternative Fig. 5 embodiment, the filling members 13, 14, which are aligned with their wider ends adjacent, are filled from a single hopper 15 which performs the function of evenly distributing the filling height when reciprocated by an hydraulic or pneumatic cylinder 17, between an initial filling and a final position over member 13, and a filling position over member 14.

Patent GB-437228-A (GB)
Abstract: 437,228. Two-stroke engines. ROBINSON, W., 154, Trafford Road, Eccles, Lancashire. Nov. 21, 1934, No. 33454. [Class 7 (ii)] When the engine fires, an annular chamber V between the cylinder wall and the larger portion of a two-diameter piston is opened to the atmosphere by a valve P to draw in air as the piston descends. The valve P closes the chamber V before the skirt of the piston reaches a byepass S normally closed by a valve R which opens as the piston reaches its lowest position to allow air compressed in the crank case J to pass to the chamber V. Just prior to reaching the end of its stroke, the piston uncovers ports D to admit from the crank case J through a pipe H scavenging air to drive the burnt gases past the exhaust valve N. As the piston rises, the valve P opens the passage E, from the chamber V, to the combustion space past a carburetter F and inlet valve G, the remaining part of the scavenging air and the charge from the chamber V being compressed in the usual way. The charge supplied is adjusted by using a variable cam to operate the valve P. The valve G may be locked in the closed position by a roller G<1> connected to the valve P which may be of either the piston or rotary type.

[Also in Division E2] Coat hangers are mounted on rails 1 by rollers 3 and a swivel joint 5 and comprise a carrier yoke 2 and a securing yoke 8, the latter being slidable vertically on a pair of bars 6 and carrying a lock 7 which requires insertion of a coin before its key 9 can be removed. A customer first hangs his coat on the yoke 2 and then pulls down the yoke 8 from its upper position in which it has been held by balls 40 in notches 38. A coin inserted in a channel 22 falls into a passageway 23 which is formed in a slide 21 and has one wall defined by a leaf spring 24 and, when the key is removed, a bolt 25 fitted on the slide and entered in a hole 28 in the key draws the slide with the key. As the key is withdrawn, a wedge-shaped lifter 29 enters the coin passageway and so presses the coin as to tilt the spring 24 clear of the front face of a stop 31 for engagement with an inclined face 32. Should no coin be inserted, withdrawal of the key is blocked because the spring 24 is not moved clear of the stop 31. The spring also actuates a lever 33 for operating a counter. Initial movement of the key frees a bell-crank lever 14 and allows a spring 13 to move a lock slide 10 into engagement with teeth 6a on one of the bars 6 so that the yoke 8 is locked in position. Upon the later re-introduction of the key, a sloping surface at the front end pushes aside the bolt 25 and formations 19 allows the key to move past a tumbler roller 18 and engage the lever 14 so that the slide 10 is disengaged from the teeth 6a and the yoke 8 can be raised. Coins released from the passageway 23 fall through a funnel 41 into a box 42.
