Abstract: ABSTRACT           A diaphragm pump, particularly for conveying flammable media, has a housing whose interior is divided into a pumping chamber and a second chamber by a deformable diaphragm having a marginal portion which is clamped between two sections of the pump head and being deformable by a cupped member which is biased in one direction by a coil spring and is movable in the other direction by a plunger receiving motion from a motor and being in mere abutment with the bottom wall of the cupped member.  The housing defines a first set of gaps which connect the second chamber with the atmosphere and a second set of gaps which connect the atmosphere with the pumping chamber.  The dimensions and shapes of the gaps are such that they do not permit the propagation of ignition from the respective chamber to the atmosphere.

Abstract: ABSTRACT         Garments covering the arms and upper torso made of a one-piece or multi-piece pattern in which the central axis of the sleeves are naturally positioned forward of the lateral plane of the body (rather than with the conventional fitted position placement in the lateral plane).  The low point of the armhole is advantageously at the side front in the center of the armpit when the arm is raised.  The garment is fitted to accom-modate arms positioned at an angle substantially forward of the lateral plane of the body, preferably ranging between about 18° and about 45°.  Contrary to conventional wisdom, the garments fit a body position which is in the center area of the natural arm movement range relative to the torso and which is naturally unsymmetric between front and back.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention is concerned with apparatus for harvesting mushrooms and the like.  The apparatus comprises cutting means such as a knife which may be moved over a mushroom bed to sever mushrooms in the bed and lifting means for removing the severed mushrooms from the bed and transferring them to collecting means.  The lifting means comprises an air mover.  The air mover is comprised of a cylindrical chamber or bore having an inlet disposed above the cutting means and an outlet communicating with the collecting means.  Compressed air is directed into the chamber through an annular orifice which is so profiled to cause the air stream to flow towards the outlet.  A zone of low pressure is created adjacent the chamber inlet which draws ambient air into the chamber.  The cut mushrooms are lifted into the chamber, are entrained in the stream of air passing through the chamber, and are delivered onto the collecting means which preferably is a conveyor.          In a preferred embodiment, the knife and lifting means are mounted on the end of an elongate conveyor frame which is movable horizontally and vertically about a support column so as to impart maximum manouverability to the cutting knife and lifting means.

Abstract: THE USE OF EUCARYOTIC PROMOTER SEQUENCES IN THE PRODUCTION OF PROTEINACEOUS MATERIALS          ABSTRACT OF THE DISCLOSURE            This invention concerns the use of inducible promoter sequences in the production of elevated amounts of pro-teinaceous materials by transformed eucaryotic cells. Eucaryotic cells which have been cotransformed with DNA which includes a gene coding for a desired proteinaceous material such as insulin, human or bovine growth hormone, or an antibody and an inducible promoter sequence and with DNA coding for a selectable phenotype will, in the pres-ence of an inducing agent for the promoter, produce ele-vated quantities of the desired protein.  This approach can be used in combination with gene amplification tech-niques to produce particularly high amounts of desired proteins.            This invention also provides methods for the therapeutic treatment of genetically defective eucaryotic cells and of persons suffering from genetically-based diseases or ill-nesses such as sickle cell anemia.

Abstract: OMEGA HALOGENATED FATTY ACIDS                 Abstract of the Disclosure A novel process of preparing known and novel pharmaceutically useful omega substituted radioactive isomers of fatty acids from industrially available macrocyclic musk lactones, lactones and dilactones is disclosed.  The process involves saponifying a lactone or dilactone, treating the resulting omega substituted hydroxy fatty acid to render the omega position recep-tive to the substitution of a radioactive isomer of a suitable substituent radical, and substituting a radio-active imaging isomer of a suitable substituent radical in the fatty acid at the omega position.  The process provides an inexpensive and secure source of 16-iodo-hexadecanoic acid and 17-iodo-heptadecanoic acid which are valuable known radioactive imaging compounds.  The novel process also provides a ready and inexpensive access to a large number of novel omega substituted radioactive isomers of fatty acids including novel omega halogenated fatty acid analogs.

Abstract: ABSTRACT         Disclosed is a process employed for loosening agricul-turally used soil, particularly for the in-depth loosening of compacted soil by injecting air into the soil.  To do so, a probe is pulled through the soil continuously in a direction substan-tially parallel to its surface.  While the probe is being conveyed through the soil by a tractor, for example, compressed air is abruptly released at intervals in eruptive bursts so that soil loosening is achieved in a continuous operational flow.

Abstract: ABSTRACT            A continuous passive motion (CPM) device for the hand which selectively provides continuous passive motion to the metacarpophalangeal (MP) and/or interphalangeal (IP) joints of selected fingers (excluding the thumb) of the joints of the hand.  The device consists essentially of two components: a hand drive unit that mounts to a forearm splint, and a microprocessor based controller drawing power from a rechargeable power pack.  The hand drive unit includes a housing having a base portion mounted on the forearm splint for supporting the motor and other control components, and a gear drive train for conveying rotational movement to the joints of the fingers.  The housing in-cludes two arms which extend from the base portion down the sides of the patient's hand.  A gear train is included in each arm.  Movable drive arms are connected to either of two points on the drive train.  The point of connec-tion, which is coaxial with one of two separate gears in each train, causes rotation of the drive arms about an axis which defines metacarpophalangeal (MP) joint motion or interphalangeal (IP) joint motion in the joints of the attached fingers.  The ends of the drive arms are connected to a finger drive rod.  The drive rod is selectively connected to the fingers of the hand utiliz-ing drive blocks which comprise a rectangular slotted plastic block mounted on an adhesive tape.  The drive rod passes through the slot on the block to con-vey the rotational motion of the drive arms to the finger joints, the adhesive band is wrapped around the appropriate portion of the finger which is to under-go continuous passive motion treatment,  For interphalangeal (IP) joint motion, the block is adhesively attached to the distal phalanx.  For metacarpophalangeal (MP) joint motion, the block is attached to the proximal phalanx.  The arms of the housing and the gear train are designed so that the axis of motion of the drive arms lies as close as possible to the axis of the joint to be exer-cised when the CPM device is in place on the hand.

Abstract: ABSTRACT: Differential amplifier.           A first and a second transistor (T1, T2) whose emitters are connected to a common point (4) via first resistors (R1, R2), which common point is connected to the positive power-supply terminal via a current source (I1), form a differential amplifier to which an input signal (Vi) is applied.  In order to increase the slew rate the quiescent current through the first and the second transistor (T1, T2) is made to increase when the input voltage (Vi) increases. This is achieved by means of a third transistor (T3) whose emitter is connected to the common point (4). The base of this transistor (T3) is connected to the tapping of a voltage divider which is arranged between the bases of the first and the second transistor (T1, T2) and which comprises second resistors (R3, R4). When the input voltage increases the transistor (T3) drains a continually decreasing portion of the current from the current source (I1).
