Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to the preparation of spray-dried powders of low bulk density.  Fabric washing powders containing nonionic surfactants as the major or sole detergent-active species have unacceptably high natural bulk densities (about 0.6 g/l).  It has been found that the incorporation of certain alkenyl succinate salts into the crutcher slurry can reduce the bulk density of the resultant spray-dried powder.  There is also a need for absorbents of low bulk density for manufacturing nonionic-surfactant based powders by dry-mixing routes and it has been found that suitable absorbents can be prepared by adding alkenyl succinate to a slurry of the chosen ingredients and spray-drying.

Abstract: ABSTRACT OF THE DISCLOSURE        A shroud is detachably engaged around the neck of a light bulb and is detachably sealed to the bulb at this point so that it is leakproof.  The shroud extends upwardly around the bulb and is spaced therefrom.  Liquid or crystal fragrance, deodorant, insecticide or the like is poured in-to the lower portion of the shroud surrounding the light bulb so that when lit, the heat from the bulb vaporizes the liquid or crystals and the vapor is dispersed from the open upper end of the shroud by convection air currents.  An elastomeric O-ring is in wedging contact between the lower end of the light bulb and the lower end of the shroud imme-diately above the sealing material in order to protect the sealing material from liquids within the shroud.

Abstract: ABSTRACT OF THE DISCLOSURE         A cutter construction for a vegetable peeler that has a cylindrically electrically rotatable body with a longitudinal mounting shaft and a plurality of longitu-dinally extending slots coextensive with and equally spaced around the body and a cutter blade disposed lengthwise from the body outer end to the inner end in each slot.  In this general arrangement an improved slot and blade configuration is provided wherein each blade is disposed in its own slot with its entire cutting edge angled or slanted in the direction of rotation and with a high point in an operable permissible range above the body periphery a maximum of .0303 inches (.75 mm) and a minimum of .008 inches (.20 mm).  A clearance recess is provided below and coextensive with each blade and extending substantially at right angles to the blades in the direction of rotation.  It has a peripheral width from substantially 0 inches to .180 inches (4.5 mm).          Thus, the width of the recess varies inversely with the blade height within the range so that clogging of peelings and cutting of the user's skin is at a minimum.  A preferred specific range is defined and the cylindrical peeler may have a flared end shield in the inner end to guide peelings away from the shaft and the recesses and the peeler may have a spaced knob on the outer end for removing the shaft and cutter without contacting the knife surfaces on the cutter.

Abstract: Abstract of the Disclosure A heat exchanger for heating liquids with other liquids or vapours.  An inner flow tube is carried concentrically within an outer flow tube to define an inner passage and also an annular passage.  A first manifold directs all of the incoming fluid from one fluid source to either the inner or annular passage.  A second manifold directs all of the incoming cooler fluid from the other fluid source to the other passage.  A third manifold at the other end of the outer tube discharges the fluid from it so that it does not mix with the inner tube fluid.          The outer tube is immersed in inner tube fluid to cause heat transfer through the walls of the inner tube and outer tube.

Abstract: ABSTRACT OF DISCLOSURE       A high yield technique for converting round logs of balsa or other species of wood of relatively small diameter into large rectangular panels, the percentage of log volume that is converted being substantially greater than      with prior techniques.  The logs are radially sectioned into sectors having the same apex angle.  Each sector is then longi-tudinally cut at its apex and arc to define a truncated feed-stock piece whose cross-section is that of an isosceles trape-zoid, the feedstock pieces being of variable width depending on the diameters of the logs from which they are derived.  The pieces are fitted together in a complementary manner to create uniform layers which are superposed to form a stack defining a dry block assembly.  The end pieces in each layer are con-stituted by feedstock piece halves to present a vertical block edge.  All feedstock pieces in the dry block assembly are then wet-coated with a curable adhesive.  The wet assembly is placed in a press and subjected to compression in orthogonal direc-tions until the adhesive is cured and the pieces interlaminated to provide an integrated stock block.  The stock block is then removed from the press and divided into panels of the desired thickness and grain direction.

Abstract: ABSTRACT     A manual electric cigar lighter for automobiles and the like, comprising holder device presenting an outward-ly facing socket, and a unique ignitor plug receivable in the socket.  Disposed at the inner end of the plug is a heat-ing element which is electrically connected in circuit with a heat-responsive switch that is also carried by the plug.  The socket in addition to its grounding circuit has a "hot" contact which is engageable with a cooperable contact on the plug to close the circuit through the heating element.  The plug comprises a manually operable part by which the heat-responsive switch can be closed, thereby to complete the heating circuit through the element.  A bimetallic member is also carried by the plus, engageable with one of the switch parts and always normally lying in a closed-circuit position when cold.  Following initial actuation of the manually oper-able part, the member receives radiant heat from the heating element, and snaps to a circuit-opening position to thereby interrupt the lighter circuit and de-energize the element after useful incandescence has been reached.  Central portions of the bimetallic member are free and not attached anywhere to any parts of the plug, but instead are merely disposed in close proximity to one of the switch parts, such that the member can quickly effect opening of the switch without need for mechanical securement of its central portions.  The ad-vantage of the present construction over many-of the devices of the prior art is that there are eliminated problems pre-viously associated with the usual fastenings made to the bi-metallic member, such as securing a contact to the member, etc.  An especially simple arrangement wherein a spring is employed to secure the member in its operative position, re-sults in improved reliability of operation, and reduced manu-facturing cost.
