Title: Anti-skid brake control system
IPC: B60T8/66
Filed: 1974-01-24
Abstract: 1460851 Antiskid braking systems EATON CORP 24 Jan 1974 [26 Jan 1973] 03412/74 Heading F2F An antiskid braking system for a vehicle having at least first and second spaced apart independently rotatable wheels comprises brake control means responsive to a skid signal for relieving braking pressure on the wheels, means for providing first and second wheel speed signals, a logic circuit for providing a skid signal to the brake control means when the acceleration rate of the faster wheel exceeds a predetermined positive acceleration and means for inhibiting the logic circuit from providing the said signal when the positive acceleration rate of the faster wheel attains a level representative of a second predetermined acceleration greater and more positive than that of said first predetermined acceleration. Sensors WS-1, WS-2 supply alternating signals to circuits SC-1, SC-2 each including a frequency to voltage converter and wheel speed signals are supplied to a summing amplifier SA and a high wheel speed selector HS. An accelerationdeceleration logic circuit A.D. provides a signal representing rate of velocity change to a comparator A.C. where it is compared with a reference signal. If the acceleration is greater than the reference signal a skid signal is provided but if it reaches the upper level of 5g a circuit AI inhibits comparator A.C. from providing a skid signal. If the average wheel speed signal decreases sufficiently fast its magnitude becomes less than the decaying reference signal and a skid signal will be provided but a circuit DFD delays it before application through an OR gate to the valve driver circuit VD, this time delay permitting the faster wheel to be braked for a longer time to have greater braking effect on the vehicle. The valve driver circuit is disabled if there is a low output voltage from the power regulator or if the OR gate provides an output signal greater than one second in the absence of a skid signal from circuit AC. A signal from the gate in excess of six seconds causes a fuse F to blow and loss of valve solenoid continuity or operation of the solenoid in the absence of a skid signal will also cause the fuse to blow, an indicator circuit IC also being provided.

Title: Improvements in pulsators for milking machines
IPC: A01J5/12
Filed: 1935-02-08
Abstract: 433,677. Cow-milkers. AKTIEBOLAGET SEPARATOR, 8, Fleminggatan, Stockholm. Feb. 8, 1935, No. 4092. Convention date, Feb. 9, 1934. [Class 84] In a pulsator for milking-machines, the alternate supply of two different pressures for operating the teat cups is regulated by the combination of a slide valve with a disc valve. As shown, a pulsator for operating four teat cups in. sets of two comprises an oscillating spindle 19 carrying disc valves 1, 2 co-operating with seatings 5, 6 and slide valves 3, 4, each slide valve with its disc valve operating two teat cups. The disc valves 1, 2 relate the nipples 13, 14<1>, each connected to one pair of teat cups, alternatively to a chamber 25 communicating with a vacuum pipe 26 through pulsation chambers 9, 10, while the slide valves 3, 4 relate them alternatively to the atmosphere. through recesses 7, 8 and channels 14, 16, 15, 17, and a filter 18. Chambers 9, 10 communicate with chambers 11, 12 containing bellows 20, 21 mounted on spindle 19. Each bellows consists of a cast bowl 38, e.g. of hard rubber, over the mouth of which is stretched a flexible rubber hood 39, the two bellows being connected by a channel 22 in spindle 19. The alternations of pressure in chambers 11, 12 cause alternative inflation and deflation of the bellows which in the inflated position are acted upon by springs 23, 24 causing rapid reversal of spindle 19 and the valves. The valve system is locked in position when not in operation by a plunger 28 engaging a collar 27 on spindle 19, the plunger being attached to a piston 29 which is pressed into engaged position by a spring 301 but is withdrawn when the pipe 26 is connected to vacuum. The open area of the slide valves 3, 4 is arranged to give a greater resistance to the air streaming into the teat cups than is met by the air passing out to the vacuum pipe, giving a slower change from vacuum to atmospheric pressure than in the reverse step. In a modification, a single valve disc is employed which admits atmospheric pressure alternatively to two pulsation chambers which are alternatively related to vacuum by a pair of slide valves,

Title: Improvements in machines for constructing brick walls and the like
IPC: E04G21/22
Filed: 1962-02-02
Abstract: 971,653. Brick-laying machines. DEMAREST MACHINES Inc. Feb. 2, 1962 [Feb. 20, 1961], No. 4159/62. Heading E1V. A power-operated machine is used for laying a course of a one or two skin brick wall by a method comprising the steps of sequentially delivering bricks in the path of a brick pusher to a level immediately above the level of the course to be laid, transferring each brick horizontally into position directly above the course, pushing the brick downwards and laterally shifting it a fixed distance rearward toward the previous brick. The machine is advanced along the wall at a speed that can be varied independently of the speed of operation of the other steps to thereby vary the horizontal spacing between the bricks. The machine is movable by a motor along the line of a wall on rails 26 and has a platform 46 raisable to the correct height for the course being laid in which position it can be clamped by screws 284. Bricks 34 from a shoot 32, which may have a friction-reducing covering of nylon or like plastic material, are transferred by feeder cam 36 to an elevator 38 from which at the correct height they are pushed by a pusher 60 into a brick positioning box 42 or 44. The pusher 60 is operated by a cam 65 and its stroke is adjusted to feed the boxes 42, 44 alternately, by a eccentric 259 which engages slots 256a, 256b of a selector fork 256 alternately with handles 252, 254 by the action of teeth 292 of the cam 65 on a pinion of the eccentric 259. This mechanism can be rendered inoperative when a single skin wall is being built. A tamper 74 operated from a cam 70 forces a brick 34a, Fig. 12, to open the spring-held sides 400, 402 of a positioning box and forces the brick on to a layer of mortar 410 laid by a shoot 420. An hydraulic or air-operated shover 430 controlled by a timing cam then pushes the brick towards the previously laid brick 34b thus it is said forcing the mortar into the vertical space between the bricks.
