Title: Electric starting systems for internal combustion engines
IPC: F02P19/02
Filed: 1933-07-07
Abstract: 420,388. Starting prime movers. BOHLI, J., 15, Dammstrasse, Solothurn, Switzerland. July 7, 1933, No. 19278. Convention date, July 14, 1932. [Class 38 (iv)] In an electric starting system for internalcombustion engines a push button operated switch o is arranged so that in its first position the starter motor b is energized in series with an auxiliary field winding f through normally closed upper contacts on the main starter contactor, so as to cause reverse rotation of the motor. In the second position of the switch a coil g is energized and moves the starter pinion d into engagement with the engine flywheel a, at the same time closing a switch h which causes energization of the main starter contactor to close the main starter circuit at l and connect the field coil f in parallel with the motor armature so as to assist its series field coil e. When the switch o is released after the engine has started, the starter switch l is first opened by opening of the contact h due to de-energization of the coil g, the pinion is dis-engaged from the flywheel and the coil f is re-connected so as to produce a reverse torque and stop the motor rapidly. Finally all circuits are de-energized. In Diesel engines an additional contact on the push switch controls a relay coil r in the first and second positions of the switch o so as to close a switch q in the circuit of incandescent ignition plugs s. At the same time an indicator lamp t is energized.

Abstract: 625,264. Moulding composite building slabs. SCHWARZ, A. July 1, 1946, No. 19652. Convention date, July 3, 1945. [Classes 22 and 87 (ii)] [Also in Group X] A building block, Fig. 3, having an inner core of gypsum 17, is made by casting a layer of concrete 14 on the bottom 34, Fig. 4, of a mould, inserting a wooden or metal frame 46 into the mould with parts 49 extending into the concrete layer, casting the inner core of gypsum, removing the frame, filling the mould with concrete and levelling the top surface of the concrete. The parts 49 prevent the penetration of the gypsum underneath the frame 46. The gypsum is poured onto a baffle plate 59, Fig. 10f, to prevent disturbance of the still wet concrete and to mark the height of the core required. The moulds are moved along a conveyer consisting of rollers having spaced wheels between which U-shaped supports 35 for the mould are guided. The travel of the moulds on the rollers causes a slight vibration of the moulds. After moulding, the blocks are stacked and cured by passing hot air over them. The mould comprises angle irons 37, 38 (not shown) connected by wing nuts 39 and bolts which engage in spaced holes in the angle irons. Liners 40 may be provided on the walls of the mould for forming grooves in the side and end walls of the blocks. The blocks may be reinforced with wire meshes and rods. The reinforcement may be pre-stressed. One side of the block has reinforced load bearing flanges. To make blocks containing pipes for the passage of heating or cooling fluid, a layer of dry sand, clay or cinders is placed on the first concrete layer, the pipes are pressed into the sand until about half protrudes, then a thin spray of hot paraffin or a sheet of oil paper is placed on the pipes and the sand layer, then a light gypsum layer is added, and the biock finished as before with a gypsum core and concrete sides. The gypsum composition, which is quick-setting, is made by mixing 10 pounds of infusorial earth with 16¢ gallons of water at 60 to 70‹ F., then adding and mixing 45 pounds of semi-hydrated gypsum. The excess water in this mixture, which water evaporates during curing, improves the bond between the gypsum and the concrete.

Title: Pneumatic jar ramming molding machine for foundries
IPC: B22C15/10
Filed: 1927-07-26
Abstract: 293,577. Lewis, W. July 26, 1927. Moulding-machines.-Relates to jam-ram moulding machines having an automatic multipart sliding valve arranged within the jarring plunger and consists in detailed improvements therein. The plunger contains a valve-chamber C connected to air pressure supply at I and to exhaust at 2. A valve D, Fig. 2, having a small free movement relative to the main valve V is adapted to control the exhaust from the jarring cylinder at 2 and from the inside of the valve V at 11. The valve V carries a sleeve S which rests on a shoulder w of the chamber C and supports by a spring K, a body B within which the valve V slides. The valve V has a close sliding fit with the cap B<2> and sleeve S and has packing to make tight fit at V<3> where it engages the body B. When air is admitted at I, the parts being in the position of rest shown in Fig. 2, it passes outside the cap B<2>, by clearances not shown, through holes H, X, and E to apply pressure on both sides of the piston V<2> and through choke-holes 15 to lift the plunger J, sleeve S, and body B, while the valve V is pressed down to close the exhaust openings 2, 11. When the body B is arrested by contact with the piston V<2> the valve seats B<1>, C<1> approach and cut off the air supply to the cylinder I and at this time the sleeve S closes the openings H. The momentum of the plunger J then lifts the valve V away from the valve D thus exhausting the inside of the valve stem and the space above the piston V<2> so that the pressure trapped at Y below this piston lifts it rapidly thus picking up the valve D and exhausting the cylinder. Air entering through the choke-holes E continues the upward movement of the valve V at a reduced rate but faster than the fall of the plunger J until, as it approaches the cap B<2> some of the holes X are covered and the relative upward movement of the valve V is checked thus avoiding impact on the cap B<2> and allowing the downward movement of the plunger J and body B to close the valve D on the seat 2 just before the plunger strikes the plate 10. Finally, the valve V rests on the valve D closing the opening 11 and then the seats B', C<1> open and the operation is repeated. To obtain an ample supply of air at the correct pressure to operate the machine a tank T, Fig. 1 with an outlet valve A and inlet and regulating valves L, R is employed. The valve A is opened and the valve L opened slowly until the plunger J and its load are balanced at this pressure being registered at G and compressing the spring 18, which tends to open the valve 17, by means of a piston 27. The cross-head 19 is then clamped to the guides 20 and the valve L opened fully so that the pressure in the tank rises to give a desired speed to the machine which may then be stopped and started by the valve A.
