Title: Butterfly-type shim having semi-opened bottom and double sandwich braze joint produced therewith
Inventor: GREENFIELD MARK S
IPC: B23K31/02
Filed: 1987-11-27
Granted: 1991-12-17
Abstract: ABSTRACT OF THE DISCLOSURE            Formation  of  a  double  sandwich  braze  joint between the steel body of a bit and a carbide insert tip disposed  in  a  groove  formed  across  the  body  is facilitated  by  a butterfly-type  shim having  a  semi-opened bottom placed within the groove between surfaces on  the  bit  body  defining  the  groove  and  adjacent surfaces  on  the  insert  tip.  The  shim has  a pair of upstanding spaced side walls and a pair of spaced bottom webs  extending  between  and  interconnecting  the  side walls  so  as  to  dispose  them  between  adjacent  side surfaces of  the bit body groove and insert tip, with lower edges of the shim side walls disposed generally above  the  bottom webs.  The  bottom webs  rest  on  the bottom  surface  of  the bit body groove and,  in turn, elevate the shim side walls so that their lower edges are spaced above the groove bottom surface. The bottom webs also support  the insert  tip  in spaced relation above the  groove bottom surface so as to define a gap which  extends  across  and  above  the  groove  bottom surface,  below the  insert tip bottom surface  and the shim side wall  lower edges,  and between the opposite side surfaces of the bit body groove. The gap will allow relatively unrestricted molten braze alloy flow across the groove bottom surface to facilitate setting up of capillary flow upwardly along adjacent surfaces of the bit body and insert tip on opposite sides of the shim side walls to produce the braze joint.

Title: System and method of navigating the travel of an autonomous vehicle
Inventor: LEMERCIER PIERRE
IPC: G05D1/02
Filed: 1988-02-01
Granted: 1994-02-08
Abstract: ABSTRACT   A navigation system for an autonomous vehicle (1).  It has a lateral row of detectors (2).  The ground has discontinuous buried magnetic markers (3) setting up a localized field which in turn produces an induced current which varies in the detectors (2) in dependence on their position.  The markers, formed by magnets (151-155) of selected polarity and number, form magnetic signatures which contain items of information for the vehicle.  The on-board vehicle computer (1) can deduce its lateral position and the controls to be carried out to accomplish its mission. Possible application:  cleaning robots with fixed or modifiable travel without trajectory recording by the vehicle.            Fig. 5.

Abstract: Case 2992 IMPROVED AIR FLOW MEASURING DEVICE AND METHOD            ABSTRACT OF THE DISCLOSURE         There is disclosed an improved method and apparatus for measuring air flow through a stator duct of a dynamoelectric machine.  The apparatus includes an inlet venturi connectable to the stator duct, a nozzle for producing a pressure drop related to the air flow rate.  The pressure drop is measured by two pressure taps, one located upstream of the nozzle and the other located downstream of the nozzle.  The improvement includes an adjustable fan located downstream of the nozzle for inducing an air flow through the apparatus that compensates for air leakage between the inlet venturi and the stator duct.  The improvement further includes air leakage measuring sensors which compare air flow through the inlet means with an air flow reference in another part of the dynamoelectric machine.  The air leakage measuring sensors register a predetermined pressure differential in air flow through the inlet means and the duct when the fan is adjusted to induce the predetermined compensating air flow through the apparatus.

Title: Pharmaceuticals microencapsulated by vapor deposited polymers and method
Inventor: VERSIC RONALD J
IPC: A61K9/22
Filed: 1989-09-11
Granted: 1995-10-24
Abstract: A microencapsulated pharmaceutical is formed by vapor depositing a polymeric film about an active pharmaceutical agent.  The film thickness of the vapor deposited film is controlled to provide effective controlled release of said pharmaceutical agent subsequent to application.  In a preferred embodiment the pharmaceutical is an orally ingestible pharma-ceutical formed by vapor deposition of a poly-p-xylylene polymer about a core comprising an active pharmaceutical agent.  The pharmaceutical agent exhibits surprising controlled release activity inspite of the extreme inertness of vapor deposited films such as Parylene films.

Abstract: VALVE APPARATUS          ABSTRACT OF THE DISCLOSURE         The valve apparatus has a poppet valve engaging a valve seat to seal an outlet port from an inlet port thereof.   A  piston  is  reciprocable  within  a  piston chamber,  and first and second piston  ports  communicate with opposite sides of the piston.  The piston cooperates with the poppet valve and is biased to an extreme position thereof,  in  opposition  to  force  from  a  fluid  signal applied to the piston through one of the piston ports. The valve configuration can be changed in the field to be either normally-open or normally-closed by re-positioning the  piston  biasing  and  redirecting  fluid  into  the appropriate piston port using an interchangeable piston port distributing structure.   The valve can be solenoid actuated,  manually  operated  or  pilot-pressure  actuated from an adjacent valve,  and the type of valve actuation can also be changed in the field.  Also, a supply manifold member is secured to the inlet port of the valve to supply fluid thereto.  Similar manifold members can be connected together,   and  similar  valves  can  be  connected  to respective manifold members to receive air from the same supply.

Abstract: With the use of a distributor unit (4, 8), which is reciprocable over and along an oblong prepressing vat for cheese production, it has already been proposed that a uniform distribution of the whey/coagulum mixture can be achieved by means of horizontal wing rotors in a transverse distributor container (8), such rotor or rotors being rotated to lift the mixture up to an overflowing edge of the container while isolating the mixture from the turbulent mixture receiving area of the container. However, it is experienced that coagulum lumps may build up on the overflowing edge and thus disturb an even overflow. The invention provides for two interengaging wing rotors (22) mounted at the bottom of the container (8) so as to sluice down the mixture along opposite, correspondingly arched bottom/side portions (21) to a central lowermost outlet slot (20), whereby the risk of lump formations is practically eliminated without compromizing the desired uniform distribution of the coagulum.

Abstract: In order to control subscriber access to selected television programmes in a CATV system, non-standard horizontal synchronizing pulses are generated (13, 15, 17) having a greater amplitude and either a higher or lower pulse repetition rate than the contained horizontal synchronizing pulses. These are selectively added (19 ... 23, 27 ... 33) to those television programmes to be controlled. As a result, the television receiver of a nonpaying subscriber interprets the non-standard pulses as being valid horizontal synchronizing pulses thereby preventing the receiver from synchronizing its line scanning with that of the television programme, rendering the picture produced therefrom unviewable.

Abstract: Acompact low-pressure mercury vapour discharge lamp comprises two or more straight tubes (2, 3) which are interconnected by means of couplings (4), to form a discharge chamber between two electrodes (15). The electrodes are located in the outermost ends (7,8) of the discharge chamber of the lamp, these ends being connected in a gas-tight manner to a lamp base (9) incorporating the requisite contact pins (11, 12) and conductors (16).Located downstream of the electrodes (15) in the direction of the discharge current are tube constrictions (13, 14) which define around the electrodes (15) the spaces in which released ions from the electrode emission material are held concentrated, so as to fall back onto the electrode surface upon a change in current phase.The method for manufacturing the lamp commences with a straight glass tube which is coated internally with luminescent powder. The tube is then heated around annular areas adjacent the tube ends. The constrictions (13, 14) are formed in the tube wall as the tube rotates, whereafter the lamp is manufactured in a manner known per se.
