Abstract: ABSTRACT OF THE DISCLOSURE         A method is disclosed for forming a thermosetting resin pipe having a balanced compressive strength between the axial direction and the direction normal to the pipe axis.  The method includes the steps of molding and thermo-setting a thermosetting resin in a smooth zone in the front section of an extrusion screw provided in the cylinder of an extrusion molding machine.  Thermosetting is effected to such an extent that the resin after being extruded from the cylinder is capable of retaining its own shape.  The resin, optionally containing a fibrous filler, is randomly oriented.  An apparatus for producing such a thermosetting resin, and a thermosetting resin having a balanced compressive strength are also disclosed.

Abstract: ABSTRACT       Bleach Composition It would be desirable to improve upon the washing or disinfection capability of hydrogen peroxide-generating compositions at ambient to low operating conditions.  The instant invention provides bleach compositions in which an activator is adsorbed into sodium perborate monohydrate, often in an amount of 20-40% w/w thereof.  The invention permits liquid and consequently often low molecular weight activators to be readily employed in solid formulations.          Preferred activators are selected from enol esters or gem-diesters, including vinyl benzoate, ethylidene benzoate acetate and divinyl adipate.  The invention can also render N-acyl activators such as TAED more storage-stable.

Abstract: "ABSTRACT OF THE DISCLOSURE"           The invention is directed to the fumigation of soils, enclosed spaces, agricultural products and other commodities, etc., using compositions which decompose to form carbon disulfide and certain other biocidal materials.  Such fumigation can be used to control bacteria, fungi, insects, nematodes, rodents, and weeds.         Fumigant compositions are described herein as "thiocarbonates," including, without limitation, salts of trithiocarbonic acid and tetrathiocarbonic acid, and composi-tions having empirical formulae intermediate to these acid salts (such as MCS3.7, wherein M is a divalent metal ion).         The compositions are generally water soluble and can be prepared, stored, and used in aqueous solutions.  Thiocar-bonate solutions of the invention are stable during prolonged periods of storage in a closed container, exhibit a low vapor pressure, and are not flammable. For soil fumigation, thiocarbonates can be mixed with fertilizers to provide a multi-functional application.

Abstract: ABSTRACT     A system of transmitting  an information individually and secretly is disclosed.  The informa-tion to be transmitted is converted, on the transmisssion side, in accordance with a predetermined algorithm designated by two keys and then transmitted to a receiv-ing side. The receiving side is supplied with at least two keys from the transmitting side for reproducing a transmitted information by using the two keys.  One of the keys is frequently changed so that the algorithm is also changed frequently.  Accordingly, even if non-contracted receiver gets hardware for converting the information it cannot receive the transmitted information.

Abstract: AUTO-START AND MAGNETIC SHUT DOWN BATTERY     CHARGING AND SURVEILLANCE CIRCUITS     ABSTRACT OF THE DISCLOSURE     Battery   charging  and  surveillance  circuits  are provided  which  may  have either  shunt  regulation  or series regulation of the control coil.  Automatic  start up  of the charging sequence is initiated when a battery is  connected  to the output terminals  by  providing  a latch circuit which is powered  from a capacitor charged from  the high ripple voltage at the open output,  which capacitor  voltage  collapses  and  causes  a   one-shot circuit  to close,  which closes a control power cut-off device  in  series  with  the  control   coil,   thereby initiating a battery charging sequence. When the battery is  to be disconnected,  either a push button switch may be  momentarily closed or a latch operates to  open  the cut-off  device,  thus causing the output voltage of the battery  charging  circuit  to fall below  that  of  the battery  -- the  power diodes in  the  circuit  preclude back-charge  from the battery -- so that the battery may then  be  disconnected without any  substantial  current flow  and  therefore without any arcing  at  the  output terminals.  No  electro-mechanical AC power interruptors are required.

Abstract: ABSTRACT.            Charge-coupled transversal filter.    The invention relates to a charged-coupled transversal filter of the parallel-in series-out (PISO) type having a buried channel of the one type and zones diffused into the channel of the other type, which constitute the clock electrodes. The inputs also comprise a zone of the one conductivity type which is provided in the associated zone of the second conductivity type. The weighting factors are formed by means of the sizes of these zones, which constitute the emitters of bipolar tran-sistors, whose bases are constituted by the clock electrodes and whose collector is constituted by the channel. The signal to be filtered is introduced by first converting the signal into a current and by then distributing the latter over the various emitters. Stages having positive and negative weighting factors can be readily combined to form a CCD.          Fig.2.

Abstract: A device is described for securement of a bicycle pannier to a normally generally quadrangular supporting frame. The system utilizes two hooks at each side and near the top of the rear wall of the pannier and a single hook at the bottom and centrally of the rear wall of the pannier. Instead of the usual spring resiliency, the invention utilizes a system of flexible but non-resilient straps so arranged that the securement of the hooks to the frame is effected by manipulating the flexible but non-resilient strap at the front wall of the pannier. The strap system is so arranged that only a fraction of the force at which the hooks grasp the supporting frame is required when tightening the strap at the front. The advance in the art is in a firmer securement of the pannier to the frame, in reduced production costs and in an increased convenience of use.
