Title: An assembly for transferring stress from a structural member to a poured concrete mass
Inventor: WILLIAMS CHESTER IRVING
IPC: E04C5/16
Filed: 1969-07-10
Abstract: 1281202 Clamps C I WILLIAMS 10 July 1969 [16 April 1969] 34914/69 Heading E2B An assembly for transferring stress from a structural member to a poured concrete mass, includes a reinforcing rod for said concrete mass, said rod having a regular pattern of ridges, an angle bracket engageable with said structural member and having a first flange of its two flanges engaged with a side of said rod, a "U"-bolt received over said reinforcing rod between certain of said ridges and extending through said first flange, and securing means engaged with said "U"-bolt on the opposite side of said flange from said rod to generate clamping action between said rod and flange. As shown in Fig. 1, the structural member is a bulkhead 10 to which the second flange 12 of the angle bracket 13 is secured. The securing means is a sheet metal wedge 21 engaging reduced thickness portions 24 25 of the U bolt, the U bolt engaging the rod between a pair of the ridges. The reduced thickness portions of the U bolt are aligned on a slanted relationship conforming to the slope of a portion 22 of the wedge so that driving the wedge with a hammer causes tightening of the U bolt on the rod. In a second assembly, Fig. 5 two angle brackets 35, 36 are used arranged back to back and each is secured to the reinforcing rod 28 by a U bolt 32 or 33, nuts 48, 51 or 49, 50 forming the securing means and tapered washers 44-47, the two flanges 37 and 38 of the angle brackets which are back to back being traversed by a threaded section 39 of the structural member which is in the form of a rod 29, which is attached to the flanges by nuts 40, 41; the assembly is intended to transfer stresses between the rod 28 and the rod 29 which is made of high tensile material the tapering washers incline the U bolts to resist movement of the rod 29 to the right. In a third assembly Fig. 7, two reinforcing rods 52, 53 one of which constitutes the structural member are coupled together end to end by the angle bracket 57 and four U bolts 62 each secured by two nuts which engage two tapering washers; the washers are disposed such that the U bolts are inclined so that they resist compressive forces between the rods 52, 53.

Patent GB-913845-A (GB)
Title: Improved electric switch
IPC: H01H1/20
Filed: 1960-10-21
Abstract: 913,845. Retractive switches. ARROW ELECTRIC SWITCHES Ltd. Oct. 21, 1960 [Oct. 22, 1959], No. 36132/60. Class 38 (5). A push-button switch suitable for controlling an electromagnetic contactor and which contains a pilot light to indicate that the contactor is energized has provision for testing the pilot light by manipulation of the button. The light (not shown) is housed in a translucent button 34 and depression of this button against a spring 39 causes the annular skirt 30 to depress an offset pin 24 slidable in a boss 22 carried on a plate 20 secured to the threaded mounting member 14 by screws. A basepart 10 carrying fixed contacts A, B, D and E is bolted to plate 20 and has a channel 10g in which two rectangular blocks 40 and 44, rigidly connected by a non-circular rod 42, are slidable. A spring 46 urges block 40 against the end of pin 24. A bridging contact 50 is carried on rod 42 and is normally urged against fixed contacts A and B by a spring 48. When button 34, and hence pin 24, is depressed, block 40 engages an off-centre lug 53 on bridge 50 which is thus tilted and separates from contact A before leaving contact B. Continued movement of the button 34 then causes the bridge 50 to engage and pivot on contact D such that its other end engages contact E. This bridging of contacts D and E may be used to energize a contactor. An auxiliary leafspring contact 51 is attached to bridge 50, as shown, such that the initial tilting of bridge 50 causes contact 51 to engage contact D before bridge 50 separates from contact B. Contacts B and D are in the circuit of a small transformer housed in the base 10 (Fig. 4, not shown), and this feeds the pilot light, which therefore lights upon slight depression of pin 24. In order to test the pilot light by causing contact 51 to connect contacts B and D without risking unintentional depression of the button 34 sufficient to energize the contactor, a cam surface 36 is provided on the annulus 30 such that rotation of button 34 through approximately 90 degrees causes the cam 36 to depress pin 24 just enough for contact 51 to engage contact D without contact B being disengaged. An arcuate rib 38 depends from member 30 so as to overlie boss 22 when the button is rotated and thus prevents depression of the button while in the rotated condition. Rib 38 also serves to prevent rotation of the button after depression, since its end surface then abuts the side of boss 22. Spring 39 is anchored at one end to plate 20 and at the other end to member 30, thus also providing rotary retraction of button 34.

Title: Improvements in variable selectivity radio receivers
IPC: H03G5/26
Filed: 1937-12-30
Abstract: 491,693. Wireless receiving circuits. HAZELTINE CORPORATION. Dec. 30, 1937, No. 36168. Convention date, Jan. 21. [Class 40 (v)] The selectivity of a radio receiver is automatically varied in accordance with signal strength by utilizing A.V.C. potentials applied to at least one stage, in conjunction with a limiter to limit the maximum band width of that stage to a value corresponding to the modulation band width of the received signal. The I.F. stage of a superheterodyne receiver comprises a forward amplifier 31 and a triode 37 having a sharp cut-off characteristic and forming part of a reverse feed-back path coupled at 38, 40 to the output and input circuits 27, 26 respectively of amplifier 31. The gain of the preselector 1, frequency changer 3 and I.F. amplifier 31 is controlled by the A.V.C. diode 14 over lead 8, while the biassing resistances 32, 33 which are common to the two valves 31, 37 are such that the reverse feed back valve is biassed to cut-off at inputs at or below the sensitivity limit of the receiver. The A.V.C. voltage thus directly varies the slope of valve 31 which in turn varies that of 37, the selectivity varying in accordance with change of product of the mutual conductances of the two valves. The characteristics of the valves must vary at different rates with variations in A.V.C. bias, and with this system the bandwidth passed increases with applied bias to a maximum and then again falls. To prevent this, an auxiliary control circuit is provided, comprising lead 44 from the junction of resistances 10, 45, a diode limiter 46, the lower part of the voltage divider 47 and through the earth connection and the resistance 33 to the cathode of the A.V.C. diode 14. The limiter 46 is in shunt with the resistance 33 and lower part of divider 47 in series, the voltage across the two latter being opposed to that developed across the A.V.C. resistance 16. Up to a certain value of A.V.C. bias determined by the slider on divider 47, the limiter is inoperative, this bias corresponding to maximum bandwidth. Thereafter, further increase in bias energizes the diode 46 which prevents further change and the ensuing droop in the bandwidth-bias characteristic is eliminated. Specification 426,803 is referred to.

Means for lubricating a fluid valve 10 comprises a pump 14 operated by the valve actuator, e.g. spindle 12 and worm 11 engaging a worm gear on rotary plug valve 10, for supplying the lubricant, the lubricant pump pressure being proportional to the resistance to movement of the valve. On turning worm 11, valve 10 is actuated, but if the resistance is too great, spindle 12 moves to left or right along the worm gear on the fixed valve, sliding, e.g. to the right through the left hand piston 13 and displacing the right hand piston 13 so that lubricant is fed to valve 10 through pipe 19 and check valve 21. Valve 25 connected to the valve 10 cuts off lubricant when the plug reaches the limit of its movement.

The reservoir and pipes are filled at 28 via a pressure equalizing valve 29. Manual lubrication may be effected at 26.
