Title: Fitted belt for absorbent garment
Inventor: LAVON GARY D
IPC: A61F13/49
Filed: 1990-12-20
Granted: 1994-10-30
Abstract: Disclosed is a disposable absorbent garment (10, 10", 10'") having a belt (12, 12', 12", 12'"). The belt may either be integral with (12", 12'") or detachable (12, 12') from the absorbent portion of the garment. The belt (12, 12") is arcuate so that one laterally extending edge (16, 16") of the belt is longer than the other laterally extending edge (16, 16") of the belt. This arrangement provides a better fitting belt which more discretely conforms to the contours of the wearer and is less noticeable under clothing. Alternatively, the belt (12'") may have a portion which is worn relatively high on the wearer's back, portions which extend diagonally downward to the front of the wearer and a portion which is worn relatively low, below the stomach of the wearer in front. This arrangement provides a belt (12'") which generally does not interfere with the portions of the wearer's body which encounter large ranges of motion during normal movements of the body.

Filed: 1938-01-08
Abstract: 509,017. Presses for separating liquids from solids. NAAMLOOZE VENNOOTSCHAP OLIEFABRIEKEN HET HART EN DE ZWAAN VOORHEEN A. HONIG. Jan. 8, 1938, No. 598. Convention date, Jan. 8, 19:37. [Class 46] In apparatus for operating the cake-moulding press of an oil-pressing installation, part of a slideway is raised periodically to receive a plate carrying a cloth, after which the part is lowered and the plate and cloth are conveyed by a pushing device to the press. In the construction shown, two angle-irons 7 are pivotally connected to levers 8 which are operated, through the medium of a cam 16 so that periodically the angle-irons are raised to receive a plate carrying a cloth. When the angle-irons 7 are lowered, a carriage 48 moves the plate and cloth into position above a pressing-plunger 1. A frame 3 is then placed on the cloth and filled with meal from a hopper 5. Afterwards the hopper is withdrawn and its place taken by a member 6. The plunger 1 is then raised to compress the meal between the cloth and the head 4. Meanwhile, the carriage 48 is returned to normal position. The reciprocating movement of the carriage is caused by projections on two sets of chains which move in opposite directions, the projections of one set engaging one wall of the carriage and the projections of the other set engaging the opposite wall. Specification 405,056 is referred to.

Filed: 1959-01-07
Abstract: 889,860. Potentiometric voljage measurement. CARTON, J. Jan. 7, 1959, No. 658/59. Class 37. An electrical servo system comprises a bidirectional motor controlled by an error signal to reduce the value thereof, and having two separate energizing windings connectible to a voltage source over separate series-connected contacts of two separate change-over devices, one being controlled in synchronism with an alternating voltage superimposed on the error signal and the other being operated through a relay controlled by the resultant of the error signal and the alternating voltage, so that when the error signal is zero the change-over devices are operated in synchronism and neither motor winding is energized. Fig. 2 shows a servo-operated system for measuring a direct voltage 17 derived from e.g. a temperature-responsive thermocouple which is balanceable against the output of a D.C. energized potentiometer 3 superimposed in series upon an A.C. from generator 6 driven by motor 7 and the coil 8 of a galvanometer which on passage of current opens normally closed contact 21 to change over moving contact of a relay 9 from the right to the left contact so that forward winding 12 is energized and reverse winding 13 is de-energized in motor 11 adjusting potentiometer 3 and recording stylus 1. A 180- degree cam 14 driven with generator 6 operates change-over contacts 15 so that for balance between the input and potentiometer voltages, the cam interrupts the motor circuit that is energized at any instant due to the alternate operation and release of contact 21 of the galvanometer in response to the excursions of the generator A.C. Thus the motor is inoperative until unbalance exists between the input and potentiometer voltages and is then allowed to operate only in such sense as to restore balance between such voltages.

Abstract: 721,806. Automatic frequency-control systems. STANDARD TELEPHONES & CABLES, Ltd. Jan. 9, 1953 [Feb. 28, 1952], No. 719/53. Class 38 (4). [Also in Group XL(c)] A travelling-wave amplifier tube, which may be constructed substantially as described in Specification 668,554, [Group XL (c)], is used for mixing the microwave amplified or generated therein with a wave of lower frequency fed to the tube to vary the velocity of the electron stream; and a side frequency selected from the tube output is stabilized in frequency by the use of one or more frequency discriminators whose output controls one or both of the two input frequencies. In the Fig. 1 embodiment, the tube 3 encloses a gun section comprising a cathode 5, focusing electrode 6 and accelerator electrode 7. The input microwave of frequency f1 is fed in from a source 15 through a guide 8, and travels along a helical electrode 9 with end supports 10 to an output guide 11. The second frequency f2 is fed from a source 16, which may be modulated by a signal, through an amplifier 18 and an adjustable network 13 to the cathode 5 and focusing electrode 6, or to other electrodes, for varying the electron velocity. The output guide 11 leads to an aerial 20 and to a frequency discriminator 21 through a filter 19 tuned to select a mean frequency (f1 + f2). Any divergence from this mean frequency provides an error voltage in the lead 22 from the discriminator, and this voltage is applied to a reactance tube 17 associated with the source 16. In a further embodiment, Fig. 4 (not shown), the output from the discriminator 21 is used to adjust the frequency of the microwave source 15. In Fig. 2 (not shown) the travelling-wave amplifier is self-oscillatory, its output being back-coupled to its input through a cavity resonant at the frequency f1 In Fig. 3 (not shown) the micro-wave oscillator 15 is of the klystron or magnetron type, and is stabilized at frequency f1 by a discriminator, and the second source 16 is similarly stabilized at frequency f2 by a second discriminator.
