Title: Improvements in the Manufacture of Silica Bricks, Tiles and other Articles.
Inventor: SANKEY CHARLES HERBERT
IPC: C04B35/14
Filed: 1918-11-25
Abstract: 122,388. Sankey, C. H., and Foster, J. E. Nov. 25, 1918. Refractory substances containing silica.-Separ. ate portions of siliceous material, consisting chiefly of silica, one in relatively coarse powder and the other in a very finely divided condition, are mixed wet with animal or vegetable fibre, or both, to form a composition for moulding. Both materials may be flint, chert stone, silica rock, quartz, sand or stone rich in silica, calcined and the coarser is ground to pass through any sieve of mesh from 16 Î 16 to 100 Î 100 per sq. in. The fine material may or may not be calcined and will pass through a sieve of 250 Î 250 per sq. in. The fibre may be straw, chaff, peat, wool, hair or the like. The mixture of the two siliceous materials and fibre is mixed with water until the fibre is finely subdivided, moulded, and the articles dried and fixed at a temperature, above 1500‹ C.

Abstract: 353,213. Charging aircraft engines. MASCHINENFABRIK AUGSBURG-NœRNBERG AKT.-GES., 7, Stadtbachstrasse, Augsburg, Germany. June 27, 1930, No. 19633. Convention date, July 29, 1929. [Class 7 (ii).] For charging a twostroke-cycle aircraft engine there is provided in addition to the normal pump which supplies air below certain altitudes, a supplementary blower which at higher altitudes augments the output of the pump and is driven through a change-speed gear. As shown, a normal pump or blower 24 is driven through toothed gearing 25 and supplies to an engine 21 the necessary scavenging air at low altitudes and ground level, a second blower 26 being brought into operation at higher altitudes. The blower 26 is driven from the blower 25 through change-speed gearing 27. An air admission pipe 28 containing a non-return valve 29 is common to the two blowers, the blower 26 discharging through the pipe into the blower 24. The Specification as open to inspection under Sect. 91 (3) (a) also describes a two-stroke engine 31, Fig. 3 (Cancelled), driving a blower 34, to which air under pressure is supplied by a second blower 36. The blower 36 is driven by an exhaust gas turbine 40 and when not in use a valve in a pipe 43 allows the exhaust gases to escape into the atmosphere. At starting, an auxiliary propeller 45 mav actuate the blower 36 ; it is cut out when the engine attains the requisite speed. In a modification only one blower is used and this is driven by change-speed gear from the engine shaft. This subject-matter does not appear in the Specification as accepted.

Title: Timing or counting systems

Filed: 1973-04-26
Abstract: 1432247 Predetermined counting AMERICAN MFG CO Inc 26 April 1973 [28 April 1972] 19980/73 Heading G4D [Also in Division H3] A predetermined counter, for instance driven by clock pulses to form an interval timer, comprises a plurality of binary counting stages 35- 38; a plurality of binary coded decimal selector switches D and a plurality of comparators 52 arranged to determine when the binary count is equivalent to the decimal value set up of the switches. As shown a timer includes a power supply A; a generator B which during the charging period of the power supply produces a pulse to reset all stages of the counter to zero; a clock generator C connected to a 50 or 60 Hz supply line and employing a frequency doubling bridge rectifier CR2 to provide 100 or 120 Hz pulses at terminal 19; a set of switches D and a single MOS integrated circuit 30. When a switch SW1 is clocked the generator B conditions the inputs of a read only memory 50 to provide a reset pulse at output f to the counting stages. At the end of reset pulse from B the ROM 50 opens a gate 48 to release clock pulses to the counter; a Schmitt trigger 39 sharpens the clock pulses and gates 45-47, according to whether a terminal 18 is plugged to the positive or negative supply line, determine the phase of the pulses counted. Depending upon which a terminal 17 is plugged to a first stage may divide by 1 or 60 so the timer counts either seconds or minutes. Depending upon which a terminal 26 is plugged to, a second stage 35 divides by 10 or by 12 so as to allow for 50 or 60 Hz supplies. When it divides by 12 a decoder 34 decodes the 12 states into 10 states at the input to compartors 52. The comparators 52 are amplifiers which provide a low resistance to earth for the contacts 55 until they are marked by the outputs of the decoder 34 or dividers 36-38. So a line 60 is initially at earth potential and remains thus until the inputs to all the comparators 52 corresponding to closed contacts 55 are marked. At that point input a to ROM 50 changes and the latter provides an output at g to energize a relay RL2, signalling the end of the tuning period. If terminal 23 is alternatively connected to the positive supply line (earth) the relay will be energized at the start and released when the predetermined count is reached.

Convention date, July 10, 1933. [Class 83 (i)] Castings, extracting.-After casting a pipe in a centrifugal inclined mould 3 during its downward movement, the cast pipe is extracted from the stationary mould. The mould is then cleaned and a socket core fitted so that when moved up it is ready for the next cast. The pipe may be extracted by a clamp 34 carried by a truck C<2> having a short free movement, limited by stops 20, 23, on a truck C<1> which is reciprocated by a rope 15 and wheel 19 driven by an electric motor controlled by switches 71<a>, 71<b>. Starting from the position shown in Fig. 2, but with the extracted pipe 5 removed, the switch 71<b> is closed by hand to move the truck C<1> upwardly to the left to introduce the clamp into the socket end of a pipe in the mould, a stop 22 on the truck C<1> acting on an arm 67 to withdraw a stop 68 and an arm 24 reversing a series of two-way valves 62 controlling fluid pressure supply to cylinders 58 which thus lower a series of roller supports 56. The truck C<1> is arrested by the stop 72 on the rope 15 opening the switch 71<b> and then engaging a positive stop 73. The clamp 34 is then expanded by moving a handle 41, Fig. 7, in the direction of the arrow this acting through rods 39, 37 to move a wedge 36 to the right. Switch 71a is then closed and the truck C<1> moves down to the right and, when stops 20, 20<1> engage, the truck C<2> is moved also to extract the pipe, the arm 24, Fig. 2, reversing the valves 62 and thus raising the rollers 56 to support the pipe. The truck C<1> is arrested by its arm 17 opening a switch 71<a> and a stop 74 on the rope engaging the stop 73. Before the truck C<1> actually ceases to move a stop 28 engages a spring pressed arm 27 which has a projection 26 to engage a roller 48 on the lever system for operating the chuck and thus collapses the jaws 34 as shown in Fig. 7. At the same time the projection 22 engages the arm 67 and thus moves the stop 68 into the path of the pipe 5. The truck C<2> is then free to run down to the right and is arrested by the stop 23. If the pipe 5 sticks or breaks in the mould it is extracted by a hook 75, Fig. 13, having a handle 76 which can be engaged by hooks 21 on the carriage C<1>. In a modification, the clamp is attached to a chain 84, Fig. 16, which passes over a wheel 82, on a piston rod 81, and is fixed at 85 so that when fluid is admitted to a cylinder 79 the pipe 5 is pulled out of the mould on to supports 87.
