Title: Boue de silice aqueuse a teneur elevee en solides
Inventor: CRAWFORD ROGER A
IPC: C01B33/141
Filed: 1989-09-21
Granted: 1995-10-18
Abstract: L'invention concerne des boues aqueuses de silice hydratée précipitée amorphe à teneur élevée en solides, lesdites boues présentant une viscosité relativement faible. La boue contient typiquement environ 40 à environ 60 % en poids de silice précipitée hydratée de structure élevée. La viscosité de la boue à teneur élevée en solides est inférieure à environ 100 centipoises. L'invention concerne aussi des procédés de production de la boue de silice aqueuse à teneur élevée en solides. Dans un mode de réalisation, on liquéfie un gâteau humide de silice amorphe précipitée hydratée et on charge le gâteau humide liquéfié dans un broyeur d'intensité élevée dans lequel la silice est broyée à l'état humide jusqu'à ce que sa granulométrie d'agglomérat moyenne soit comprise entre environ 0,3 et environ 3 microns. Dans un autre mode de réalisation, on transforme en boue de la silice précipitée amorphe sèche finement divisée dans un broyeur de suspension jusqu'à obtention du niveau de solides désiré, puis on charge cette boue dans un broyeur de haute intensité dans lequel on la broie à l'état humide jusqu'à ce que l'on atteigne la plage granulométrique d'agglomérat précitée. On peut transporter en vrac la boue à teneur élevée en solides ainsi obtenue avec seulement une agitation faible afin d'empêcher le tassement. On peut aussi ajouter un dispersant à la boue avant le broyage afin de retarder le tassement de la silice.

Abstract: An exterior rearview mirror is described, having a foot which can be attached to the vehicle and on which a housing bearing a mirror housing is attached so as to swivel about the axis of a tubular piece, and having a catch device which has a first catch element on a foot part and a second catch element on a housing part directly adjacent to the foot part, the engagement of the catch elements which can be released counter to spring force defining a position of use of the housing relative to the mirror foot. So that an exterior rearview mirror of the type mentioned at the beginning having a catch device can be provided, in which mirror the frictional resistance of one of the catch elements on the corresponding face in which the second catch element is constructed is as low as possible during the folding away movement of the housing without the secure retention of the housing in the position of use being impaired, it is provided that one of the two catch elements (30) be loaded by a radially displaceable transmission element (42) which, towards a connecting link (34) close to the tubular piece on a peripheral section (36) corresponding to the catch element (30), has a different distance from the axis (20) than on a connecting link section which is adjacent to the peripheral section in the circumferential direction. Alternatively, a wall section on which one of the two catch elements is constructed can be set back on both sides of the catch element relative to a corresponding face on which the other catch element is constructed.

Title: Ski brakes for interlocking skis
IPC: A63C7/10
Filed: 1990-02-20
Granted: 1993-06-09
Abstract: Ski brakes (1, 2) useful in interlocking skis of a pair together comprising two shaped members (7, 8) having actuator (11, 12) and braking arm (13, 14) portions separated by an intermediate portion (9, 10). The members are rotatably mounted in a base plate (5, 6), the free ends of the actuator arm portions being axially aligned and connected by a coil spring (17), while the braking arms are provided with shoulders (18, 19) adapted to engage longitudinal edges (20, 21) of the skis. To accomplish interlocking, the running surfaces of skis provided with the brakes are brought together in a face-to-face relationship, causing the braking arms (13, 14) on one of the skis (3, 4) to overlie the braking arms on the other ski. This results in bringing the shoulders of the brake of the latter ski into engagement with longitudinal edges of the former ski, thereby locking the skis together.

Abstract: A process for removing volatile contaminants, in particular low-boiling and/or steam-volatile organic compounds from soils and comparable materials, especially those of which large proportions are in a bound/clayey form, by extraction and purification of the extracted gas contaminated with the materials to be removed is to be made more effective and economical. For this purpose, the material to be purified is introduced into a closed chamber in which a quasi-inert gas is introduced into the interior of this material and extracted again from the closed chamber after flowing through the material, purified and re-introduced to this chamber in circulation until the desired degree of purity of the material to be processed is reached. As the closed chamber, a transportable steel container can be used as one version, in which the contaminated soil material is aerated in removable grid boxes. In further versions, the treatment of the material is carried out continuously in gas-flooded screw conveyors or belt filters. <IMAGE>

Abstract: The main/standby filament switch is controlled by a main filament monitor. The latter is constructed as an optocoupler (U1) which is coupled on the input side, e.g. in the form of a transformer (T2), to the main filament circuit. The switching transistor of the optocoupler is at a DC voltage and, when it is set, short-circuits a light-emitting diode, which is at a supply voltage, or separates its supply circuit. This light-emitting diode is the transmitting diode of an electro-optically controllable AC switch (U2), whose receiving diodes are connected via the standby filament (NF) of the lamp (L) to the supplying current supply device (T1). When current is flowing through the light-emitting diode, the AC switch switches through an AC switch (TR) arranged in the circuit of the standby filament. The main/standby filament switch has exclusively electronic switches for carrying out the switching processes required. <IMAGE>

Abstract: An apparatus 10 controls the enable response time of a laser diode 12 during the reception of a data signal. The laser diode 12 is powered by the combined outputs from a pulse and bias current supply 14, 16. The pulse current supply 14 is connected to an external controller (not shown), which provides serial pulses of data. The pulse current supply 14 converts the serial pulses of data to a series of current pulses that drive the laser diode 12 between high and low optical output intensity. The bias current supply 16 provides a DC offset to the pulse output of the pulse current supply 14. Further, the apparatus 10 controls the level of the DC offset to maintain the minimum optical output intensity of the laser diode 12 at a preselected desired level. The apparatus 10 constitutes a closed-loop, bias-current-supply controller 20, which employs a feedback path for monitoring the optical output intensity of the laser diode 12 and controlling the optical output intensity to a preselected value. To accomplish stable operation but permit rapid response to an enable signal, the closed-loop, bias-current-supply controller 20 has a first preselected response characteristic for a first preselected period of time in response to receiving the enable signal and a second preselected response characteristic thereafter.

Abstract: The present invention provides surgical gowns and other garments possessing the advantages of raglan sleeve construction in terms of comfort and freedom of movement, with improved manufacturing efficiency. The garment (100) of the present invention provides a raglan sleeve divided into an upper portion (20) and lower portion (30) joined approximately in the area of the bicep. Waste is greatly reduced by creating a shoulder portion from material removed to form the arm openings in the body portion of the garment. The shoulder portion (20) is attached to the body portion of the garment to form a raglan shoulder portion which extends to about the bicep of the wearer. A sheet of material is cut in a trapezoidal pattern to form a plurality of lower sleeve portions, each of which is attached to a shoulder portion. Gowns made in accordance with the present invention exhibit the flow and shoulder lines of a raglan sleeve construction while making efficient use of the fabric from which the gown is constructed.
