Title: Cleansing and rinsing agents containing sodium tripolyphosphate and process for making them
IPC: C11D3/06
Filed: 1966-05-27
Abstract: Pulverent cleansing and rinsing agents containing sodium tripolyphosphate and components customarily used in these agents are prepared by dry-blending the individual components, the sodium tripolyphosphate used containing 0.5 to 22.7% by weight water at the time of blending.  The sodium tripolyphosphate preferably contains at least part of said water content as water of crystallization.  When the sodium tripolyphosphate has a phase-I content of between 5 and 100%, it should preferably contain 0.5 to 8% water and when it has a phase-II content higher than 95% it should preferably contain 5-15% water.  Sodium tripolyphosphate of the desired water content can be prepared from sodium tripolyphosphate containing less than 0.5% water by mixing it with water, e.g. in a fluidized bed, by exposing it to steam or by mixing with a proportion of sodium tripolyphosphate hexahydrate.ALSO:Sodium tripolyphosphate having a water content of 0.5 to 22.7% by weight, including water of crystallization, is prepared from sodium tripolyphosphate having a water content of less than 0.5% by mixing it with water, for example in a fluidized bed, by exposing it to steam, or by adding a proportion of sodium tripolyphosphate hexahydrate.  Sodium tripolyphosphate having the aforesaid water content dissolves freely in water without caking.

Title: Improvements in systems for signalling and eliminating faulty electric circuits
IPC: H02H3/04
Filed: 1947-08-28
Abstract: 633,399. Protective cut-out arrangements. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. Aug. 28, 1947, No. 23822. Convention date, Nov. 13, 1945. [Class 38 (v)] A system for locating and disconnecting faulty load circuits, e.g. those of the motors of a train, each having a circuit-breaker 4, 4<SP>1</SP>, &c., and in series with a common main circuitbreaker 5, comprises for each motor-coach, overload relays 10, 10<SP>1</SP>, and interlocking and signalling relays 11, 11<SP>1</SP> normally held inactive, as shown, by coils 22, 22<SP>1</SP> energized over pushbutton 6. On an overload, in, e.g., the circuit having the breaker 4, the corresponding overload coil 20 is energized to operate relay 10 which opens the circuit 23 of the main circuitbreaker 5 and energizes a maintaining coil 19. The resetting button 8 is pressed to energize a coil 13 which opens contacts in series with the coil 19, thereby de-energizing relay 10 and reclosing circuit 23. If the fault persists, the relay 10 operates again and is again locked down by coil 19. The push-button 6 is now momentarily depressed to de-energize the coil 22 and the relay 11 is operated by the coil 21 which is in series with holding coil 19. Operation of relay 11 opens the circuit of circuitbreaker 4, which thus opens, and closes over its lower contacts, the circuits of general and local pilot lamps 9, 12, respectively, the relay 11 being mechanically hooked in its new position. The resetting button 8 is again depressed and the breaker 15 is reclosed as before, the breaker 4 however remaining open. If necessary the faulty circuit is immediately repaired and the relay 11 is manually unhooked.

Title: Inseam joint forming machine
IPC: A43D9/00
Filed: 1939-08-18
Abstract: 533,785. Pounding-up lasted shoes. RAMSEY, A. R. J. (Walker. T. Dickerson Co.). Aug. 18. 1939, No. 23856. [Class 17 (i)] A pounding-up machine has a chisel point intended for conforming the upper margin to the insole rib and feather. The inseam stitches are thus positioned nearer the rib and are not cut when the sole is trimmed adjacent to the heel breast. A pneumatic hammer of ordinary form has a valve control member 12 actuated by a lever 17 connected to a treadle. The hammer piston strikes the shank 13 of a tool having a right-angled edge and guided at 22. The shoe is held by the operator so that the tool beds the upper margin, counter and lining well into the angle between the insole rib and feather. In a modification, a twin machine operates on the two sides of the shoe simultaneously, the shoe being supported on a last-pin adjustable vertically to cause the tools to approach or recede from each other.

Title: Improvements in and relating to radio receiving systems
IPC: H01Q11/02
Filed: 1920-08-16
Abstract: 175,315. British Thomson - Houston Co., Ltd., (General Electric Co.). Aug. 16, 1920. Directive signalling; aerials; atmospherics and undesired signals, eliminating or limiting. -Directional reception and marked selectivity with the exclusion of atmospherics are obtained with a long horizontal antenna in which the current wave due to the desired signal is made to travel along the antenna with the same velocity as the signal wave in space travels along its length. The antenna may be a loop, or a single wire earthed at both ends. Reflection is prevented by inserting in one or both of the ground connections an ohmic resistance equal to the surge impedance of the whole antenna. The velocity of the current wave is controlled by adding shunt or series condensers and inductances along the length of the antenna, as for instance 7, 8, 11, 12, Fig. 5. Signals are received on the set 4 from the end 2. The resistance 5 may be replaced by a second set which will receive from the end 3. Modified antennae are described consisting of a single multi-turn loop, a series of multi-turn loops, or a number of such loops inductively coupled. An alternative method of adjusting the current wave velocity is shown, Fig. 11, where links of artificial line 9, 10 are introduced at intervals to slow up the current wave and bring it into phase with the ether wave. The various adjustments give different wave velocities for different frequencies. Fig. 3 shows three curves indicating the current strength at various points along the antenna, with three different velocities of current propagation. The upper curve shows the relation when the current wave and the ether wave travel with the same velocity, and the curves H, C are for cases in which the current wave is slowed down. In the latter case nodes G, E are formed owing to interference. At the point E signals represented by the curve H will be heard while those represented by C will be inaudible. The arrangement shown in Fig. 5 acts as a transmission line for the desired frequency the added inductances and capacities acting as a high and low filter to absorb other frequencies. In antennµ of this kind, highly damped waves such as statics produce a slowly-travelling current wave and therefore a large number of points where their effect its zero. When using these antennae for stations not in line with them, the velocity of the current wave is made = C/cos # where C is the velocity of light and # the angle made by the direction of the station with the antenna. Fig. 13 shows the receivers 4 at a distance from the antenna. The transmission line is balanced and crossed at intervals so as not to act as an antenna for the upper receiver 4. As shown, it will act as an antenna, for the lower receiver 4. The transformer 14 equalizes the impedance of the antenna and transmission line. In another arrangement, the transformer 14, 15 and the lower receiver 4 are omitted, one wire of the transmission line being connected to the antenna and the other to the ground resistance 5 at the end 3.
