Abstract: FREE-FALLING, SELF LOCKING ADJUSTABLE TIP ASSEMBLY             ABSTRACT OF THE DISCLOSURE An improved tip assembly which includes a tongue plate insertable into a buckle is provided for a safety belt apparatus in which a continuous retractable belt length provides both a lap portion and a shoulder portion.  The tip assembly through which the belt passes has a snubber slide engaged with the tongue plate and slidable relative thereto.  When the belt is drawn by the passenger over his body, the belt shifts the snubber slide rearward on the tongue plate to where the belt is firmly gripped between a surface of the tongue plate and a surface of the snubber slide, whereby that portion of the belt which extends across the passenger's lap cannot expand.  When the belt is retracted so that a run of the belt is substantially vertical, the weight of the tip assembly causes its front end to tip downward causing the slide to fall forward along the tongue plate releasing its grip on the belt, whereby the tip assembly freely falls to a lower position along the vertical belt run.  To prevent the belt from miscentering and twisting within the tip assembly, the snubber slide has a pair of parallel tracks to guide the belt through the tip assembly.

Abstract: HEATED LIQUID SYSTEM INTERLOCK            Abstract of the Disclosure A motor drive for a hot melt adhesive pump is main-tained in an inoperative condition until the adhesive has heated sufficiently to permit free operation of the motor.  The adhesive is received in a container supported upon a heater which is activated to heat the container and the adhesive therein. The output of a proportional control for the heater, which is responsive to the container temperature, is monitored.          The output of the proportional control, when the container temperature in near a set point temperature indicative of a desired heated condition for the adhesive, is an intermittent signal.  In one form of the invention, the intermittent signal is electrically integrated to produce an interlock release. pulse permitting operation of the motor.  In a second form of the invention, a thermal relay is-coupled to a source of electrical power through a switching circuit, which permits power to be coupled to the thermal relay during the intermit-tent off times of the heater.  The thermal relay thermally integrates the intermittent power coupled thereto and produces an interlock release signal to permit operation of the motor.

Abstract: HIGH TORQUE EXPANDABLE SOCKET RATCHET WRENCH                       ABSTRACT        A ratchet wrench usable in areas of limited access normally requiring an open-end wrench, but possessing the high torque characteristics of a closed-end socket wrench is dis-closed.  A handle member terminates in an expandable yoke containing a fixed upper half and an expandable lower half for movement from an expanded open position for receiving a socket to a closed position in driving engagement with the socket.  A curved rib is formed transversely on the inner surface of each yoke half.  A split ring-like nut driving socket contains exterior ratchet teeth and a circular bore formed transversely through the socket with a recessed counter bore forming a circular guide channel in the socket concentric with the trans-verse bore.  The socket guide channel is received in rotational engagement with the curved ribs of the yoke halves.  The socket contains a curved head having lands which in combination define a ploygonal wrench opening.  A pawl mechanism mounted on the wrench handle member is resiliently biased into engagement with the ratchet teeth of the socket, thereby allowing it to turn in one direction only, and preventing rotation of the socket in the opposite direction.  The split ring-like nut driving socket permits circumferential engagement of a nut through movement transverse to the socket access and the two-piece expandable yoke permits engagement of the socket by means of movement of the handle member transverse to the socket access.

Abstract: Abstract of the Disclosure A method of and a plant for preheating and, possibly, heat-treating and subsequently dividing rod-shaped material into slugs A plant for preheating and, possibly, heat-treating bars (2) of aluminum or aluminum alloys and subsequently sever-ing the bars (2) into slugs (10) comprises a furnace (4) for the heat treatment and preheating only, if desired, billet hot shears (7), and a quick preheating furnace (16) connected between the hot shears and the furnace. Upon se-lection of the operating mode of heat treatment of the bars (2), the quick preheating furnace serves as cooling apparatus providing for temperature controlled cooling and corresponding renewed heating to a predetermined billet pressing temperature when the admissible temperature is not reached. When the plant operates alone to preheat the ma-terial, the quick preheating furnace serves as preheating furnace the exhaust gases of which serve to preheat the bars (2) in the furnace (4) through an exhaust gas conduit (19). This plant permits particularly economic and flexible operation, i.e. operation which is easily adaptable to batches of different compositions of alloys or conditions of textures, exact temperature control being achieved to the desired billet pressing temperature.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for producing a casting mold with chemi-cally bound moulding material using a pattern is intended to make it possible to forego the use of clay-bound sand, in particular for the mass production of cast members, and to provide a casting mould of adequate gas permeability, which is simple to produce, with a low level of consumption of moulding material, and inexpensive, and which also provides a high level of casting quality with a low degree of environ-mental pollution.  For that purpose, the moulding material which has become pourable or fluid due to the operation of casting a cast member is removed from a first casting mould comprising a single moulding material, whereas the remaining portion of the moulding material is left, and the hollow space formed when the pattern is re-fitted is filled with moulding material.  In addition, the moulding material which has been reduced in strength may be also removed, being for example blown or brushed out.

Abstract: ABSTRACT OF THE DISCLOSURE:    An integrated circuit protection device for use with a voltage regulator used to drive an integrated circuit to prevent damage to the integrated circuit which goes into a "latch up" condition.   The inte-grated circuit protection device comprises a first switching circuit,  connected to the output of the voltage regulator for selectively connecting the out-put of the voltage regulator to ground and a second switching circuit,  connected to the input and the output of the voltage regulator  and  to the first switching circuit, for detecting a "latch up" condi-tion and for selectively activating the first switch-ing circuit upon detection of a "latch up" condition, whereby the first switching circuit connects the out-put of the voltage regulator to ground and resets the integrated circuit to prevent damage thereto.  A pre-determined time after the  "latch up" condition is detected, normal operation is automatically restored. In another embodiment, the first switching circuit is included in an adjustable voltage regulator, but is still controlled by the second switching circuit as described hereinbefore.  In still another embodiment the protection circuit monitors  the input  current drawn by a voltage regulator and cuts the current thereto  when  the  current  exceeds  a  predetermined value caused by the "latch up" condition of the inte-grated circuit.  The output of the voltage regulator drops to zero and clears the integrated circuit.

Each bit of the I and Q bit streams has a duration of 2T, where T is the bit interval or period of a data bit.  Each of the ROMs comprises blocks of memory that contain a plurality of digital words;  The present and immediate past I and Q bits in the shift registers, and a baud clock signal of one-half the data signal rate, are applied to address inputs of the ROMs for selecting associated memory blocks in the 2 ROMs.  A counter then clocks the ROMs for sequentially outputting the contents of the addressed memory blocks to the converters which produce analog voltages that phase modulate a carrier signal for moving a resultant signal vector with a constant envelope during each bit interval.  The contents of the ROMs are selected to provide a substantially constant amplitude vector whose rate of change w of phase satisfies the criteria:       where W and 2W are constant phase velocities that rotate the signal vector a total of 45° and 90°, respectively, in a bit or symbol interval.
