Abstract: ABSTRACT     A container body made of thermoplastic materials, after being filled with a hot liquid, is then sealed by a flat closure disc adhesively contacting a peripheral lip formed around the top of the body.  The bottom of the container body is formed with annular grooves to define a diaphragm which flexes inwardly with the closure disc upon cooling of the hot filled liquid to substantially dissipate the high internal vacuum which is formed on the container head space.  The bottom of the container body has a reinforced pedestal base formed with stacking ledges to facilitate nesting of empty bodies for shipment and storage.

Abstract: Abstract of the Disclosure An automatic adaptive equalizer operative on a test pattern including a carrier-only period, clock-only period and a single test impulse.  The equalizer employs a transversal filter under control of a microprocessor.  Samples of in-phase and quadrature phase components of the received impulse response are cross correlated and autocorrelated to form elements of a complex matrix equation describing the optimum equalizer tap settings.  The microprocessor performs a special iterative operation utilizing elements of this equation to rapidly and exactly calculate the optimum initial settings for the tap constants.  The clock-only portion of the test pattern is analyzed to accurately set a sampling clock to properly sample the received impulse so that the matrix formation can be carried out during the duration of the received impulse.  Initial equalization can be achieved in a time on the order of 30 milliseconds at a data rate of 9600 bits per second.

Abstract: STABLE SUSPENSION OF POWDER IN ALCOHOLIC MEDIA     Abstract A novel fast drying stable pituitous powder suspension in an alcoholic/aqueous medium having a high alcohol content and a low water content, containing hydroxyethyl cellulose as the essential suspending agent, said alcohol content exceeding the upper solubility of hydroxyethyl cellulose in said alcohol and the water content being sufficient to prevent precipitation of said suspending agent and at least 5% by weight; having util-ity in the preparation of viscous liquid, semi-solid or solid suspension products such as creams or sticks, more specifically, roll-ons or stick deodorants and medicated lotions which may also be pump activated.  The alcohol utilized herein is monohydric such as ethanol, methyl or isopropyl alcohol.  However, a poly-hydric alcohol such as propylene glycol, glycerine and/or poly-propylene glycols may be partially substituted for the monohydric alcohol.  Sodium or potassium bicarbonate suspensions have been found to be less irritating to the body and dry faster than bicarbonate solutions because the bicarbonate is delivered as a powder to be activated by body moisture.

Abstract: A B S T R A C T            The cooling of a continuously cast ingot of metal as it em-erges from the mold is carried out by applying coolant dir-ectly to the ingot surface. In order to reduce the amount of curvature at the foot of the ingot due to too rapid cool-ing, a substance which releases a gas as a product of de-composition on striking the hot ingot surface is added to the coolant at least during the initial phase of casting. This gas forms an insulating film on the ingot surface thus re-ducing the rate of heat extraction. Particularly suitable for this purpose are substances which produce carbon dioxide or nitrogen as decomposition product.

Abstract: ABSTRACT OF DISCLOSURE     A toy vehicle has a gear box containing a clock spring which is wound by pushing the vehicle backward.  A two part toggle-linkage system connects the gear box to the frame.  When the clock spring is wound, the resulting spring bias urges the toggle-linkage system to one over center position which locks the gear box in order to preserve the energy stored in the wound spring.  When the toggle-linkage system is pressed near its center, it moves over center to another position, which unlocks the gear box and releases the energy stored in the wound spring in order to propel the vehicle.  When the vehicle is next moved backward, the toggle-linkage returns to the locked position which once again locks the gear box.

Abstract: ABSTRACT A digital computer includes a syntax examination and correction system which operates as follows.  When a programming statement is keyed in and displayed on the computer monitor in simple black on white format the structure of the statement is examined in accordance with a  predetermined set of syntax rules.  Each character within the statement is then given a pre-determined color indicia if it falls within the syntax rules but remains black if it is not in accord with the rules.  If there are any non-colored characters these are ignored and the remaining characters are examined to determine whether an acceptable program statement is defined.  If it is, an altered program statement consisting only of the colored characters is entered but, if not, the colored characters are all changed to a single shading such as grey indicating that the statement cannot be interpreted correctly.  The system assists novices in programming.

Abstract: Abstract:                 IGNITION TIMING CONTROL SYSTEM     An ignition timing control system for an internal combustion engine (18) varies the timing of a magneto (14) in accordance with a pre-programmed ignition advance schedule.  An optical pick-up (22) senses the passage of slots (26) in a disc (24) which is rotated at the speed of a distributor (16) and pro-duces constant angular width reference pulses corres-ponding to fixed ignition timing in the engine's cylinders (13).  A magnetic pick-up (36) detects incremental rotation of the engine's crankshaft (33) and produces timing control signals proportional to engine speed.  The timing control signals and reference pulses are converted to a multi-bit data word which is used to synthesize an analog control function representing variable ignition timing using a pre-programmed digital to analog converter (58).  A speed controlled switch (70) gates ignition trigger signals corresponding to the fixed timing of the reference-pulses when engine speed is below a pre-selected value but gates ignition trigger signals cor-responding to the variable ignition timing of the pre-programmed ignition advance schedule when engine speed exceeds the pre-selected value.
