Title: Bi-modal dc motor control for a motor driven anti-lock brake system
Inventor: RICKER DENNIS J
IPC: H02P7/00
Filed: 1990-08-01
Granted: 1995-02-07
Abstract: BI-MODAL DC MOTOR CONTROL FOR A MOTOR DRIVEN ANTI-LOCK BRAKE SYSTEM            Abstract of the Disclosure Differential performance characteristics are achieved in a motor-driven anti-lock braking system with a DC motor having a first brush which is employed for both forward and reverse motor rotation, a second brush which is employed in connection with the first brush when forward motor rotation is desired, and a third brush which is employed in connection with the first brush when reverse motor rotation is desired. The second and third brushes are displaced along the circumference of the motor commutator such that the first and second brushes encompass more turns of the rotor winding than the first and third brushes.  As a result, more of the winding turns are active in the forward direction, and the motor torque is maximized for developing the required brake pressure. On the other hand, fewer of the winding turns are active in the reverse direction, and the motor speed is maximized to relatively quickly retract the armature within the valve bore to relieve the brake pressure.

Title: Method of rehabilitating manholes by custom lining/relining
Inventor: STRONG WILLIAM A
IPC: E03F3/06
Filed: 1990-12-13
Granted: 1996-09-24
Abstract: A method for lining or relining a sewer manhole, apparatus comprising an improved leak resistant manhole, and a cementitious mixture for lining/relining manholes. A homogeneous, monolithic, cementitious liner is spray applied in place within a concrete or brick-and- mortar manhole infrastructure without forms, webbing, or re-bar.  A manhole to be serviced is first located and spray cleaned with water. Loose concrete and mortar fragments of the original structure are forcibly removed.   A cementitious mixture is spray-applied to the interior surfaces of the manhole to create a continuous, monolithic interior liner.  This lining is configured substantially identically to the internal shape and geometry of the manhole.  When the liner sets after installation, a substantially impervious water and chemical resistant barrier prevents manhole ingress/egress by ground water. The preferred cementitious mixture is a lightweight, high silicate, fiber-reinforced blend, which, when mixed with 20% to 40% water by weight and properly spray applied, will produce a monolithic liner having hitherto undiscovered geometric and structural strength characteristics, including improved water impermeability and chemically resistant properties. The disclosed structure and process contribute positively to the promotion of improved sewer system integrity.

Abstract: Des familles d'antagonistes-agonistes et de stupéfiants opiacés sont préparées à partir de la norhydrocodéinone.  Dans une concrétisation préférée de l'invention, la norhydrocodéinone est chauffée au reflux avec le diméthylcétal sulfosalicylique et des dérivés éther du delta-6-énol, puis est convertie entièrement en éther par l'addition de tétrahydrofurane anhydre en même temps que l'élimination de l'éther ainsi produit.  Ensuite, on fait réagir l'éther avec de l'acide méthanesulfonique et du N-bromoacétamide pour obtenir le bromhydrate du dérivé 7-bromodiméthylcétal. On peut obtenir, à partir de ce dérivé, divers produits dont le nouvel intermédiaire plus poussé 14-hydroxynorcodéinone.  La présente invention permet d'obtenir des dérivés à partir d'un produit de départ qui, contrairement aux produits de départ des procédés antérieurs, est disponible sous forme naturelle (-) ou synthétique (+). Ainsi, la méthode décrite dans la présente invention est la seule connue qui permette de synthétiser les formes (+) des divers dérivés et intermédiaires, comme la (+)-7-bromo-diméthylcétal-nordihydrocodéinone.

Abstract: In a temperature regulator for soldering and unsoldering equipment having a heating device fed by a controllable electric source of heating current, the heating output of which is transmitted to a spot to be soldered by a heating output transmission device, a signal that is proportional to the temperature of the heating device is generated and compared in a comparator of a control circuit to a set value.  The control circuit derives from the output signal of the comparator a control signal for controlling the source of heating current. In addition, a temperature sensor (5) is arranged in the area adjacent to the spot to be soldered of the heating output transmission device (3), the output signal of which is compared in another comparator (23) of another control circuit (23,27,28) to another set value (7). The second control circuit supplies another control signal for controlling the source (11) of heating current. The control signals from the first control circuit (13,17,18) are supplied to the first input and the control signal from the second control circuit (23,27,28) are supplied to the second input of an AND logical element (20), the output signal which only switches on the controllable source (11) of heating current when both control circuits simultaneously supply output signals for temperatures lying below the respective set values.
