Abstract: ABSTRACT OF THE DISCLOSURE             Burner control apparatus includes control devices for actu-ating an ignition control means, and a timing circuit for providing an ig-niton timing sequence of four precise intervals.  The timing circuit is ac-tuated in response to a request for burner operation and the control devices are energized in sequence and combination in response to the actuated timing circuit.  Time sequential pilot flame and main flame stabilization inter-vals are provided.  If a signal from the flame sensor is received before the end of the overlapping flame stabilization timing intervals, the control de-vice is energized and if flame detection signal is lost a lockout circuit is energized.

Abstract: Abstract of the Disclosure The proposed apparatus for treating a cellulosic material with a gaseous agent comprises a vessel with means for introdu-cing the pulp and the gaseous agent there~into and withdrawing them there~from. The vessel is further provided with a false bottom arranged at an angle of 1 to 40° to the horizontal and inclined towards the pulp outlet. The chamber formed by the false bottom and the vessel bottom is divided by transverse walls into a plurality of isolated compartments, each being co-nected with a respective means for introducing the gaseous agent. Above each compartment, there is located a level pickup constituting a part of a means for controlling the level of the pulp layer. Each pickup is operatively associated, via a corresponding gas flow meter, with a corresponding means for introducing the gaseous agent.     The proposed apparatus permits cellulosic material of any consistency to be treated with the gaseous agent, ensures maximum contact therebetween by using the energy of the gaseous agent to transfer the pulp being treated in the vessel.

Abstract: Abstract of the Disclosure Disclosure is made of novel temperature sensing devices such as temperature indicating and recording devices. The devices of the invention differ from prior art devices in that they employ new and improved temperature indicating com-positions.  The temperature indicating compositions of the invention comprise an optically active, inert compound in Admixture with nematic type liquid crystal compounds.  The optically active, inert compounds lend a visible point of reference to the compositions when the liquid crystals pass through their liquid transition points.  The proportion of optically active, inert compounds added to the nematic liquid crystals is that proportion which will impart chirality or twist to the compositions of the invention and is dependent upon the twisting power of the optically active ingredient. The compositions of the invention are unique in that they possess very sharp liquid transition points, i.e.; clearing points over a very narrow temperature range.  This is an ideal characteristic for compositions to be employed as accurate sensors of specific temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE         A dry-break coupler attaches to an adapter for loading fluid into the bottom of a tank.  The coupler and the adapter can be connected or separated without the loss of fluid, while both fittings are subjected to internal fluid pressure.  The coupler is of the type used on a gasoline tank truck loading arm, and the adapter is in accordance with the standards of the American Petroleum Institute.  The coupler has a tubular body that defines a central flow passage and a movable valve closure element that opens and closes the coupler flow passage.  This valve closure element also actuates a central valve of an adjacent adapter.  An adapter latch is mounted upon a first rotatable shaft that is pivotally mounted on the coupler tubular body.  A second rotatable shaft that operates the valve closure element is mounted within the tubular body.  Portions of both the first and second rotatable shafts extend in substantially parallel rela-tionship.  Mounted on the shafts is a mechanism intercon-necting the shafts for both pivoting the adapter latch into locking engagement with the adapter before the valve closure element opens the flow passage and holding the adapter latch in a locked position while the flow passage is open.  A single handle operates both the first and the second rotatable shafts.                             -1a-

Abstract: "METHOD OF CONTROLLING FOAMING OF CABINET INSULATION"   ABSTRACT OF THE DISCLOSURE         A method of controlling the foaming of foamed-in-place insulation in a cabinet structure having an inner liner and an outer shell with the liner having an outer surface and the shell having an inner surface in outwardly spaced confront-ing relationship to the outer surface of the liner at a front opening of the cabinet.  A flexible sheet is secured to either the outer surface of the liner or the inner surface of the shell at the front opening and has a preselected stiffness so as to cause the sheet to project away from the surface to which it is secured whereby the foaming of the insulation may carry the projected portion to the front opening of the insulation space.  A backup member may be disposed across the opening so as to limit the outward deflection of the strip by the foam whereby the strip defines the outer boundary of the foamed insulation across the opening.  A portion of the opening may be defined by an inturned flange and the sealing strip may further be urged against the flange by the foaming insulation.  The strip may be transparent to permit observation of the insulation formation at the opening.

Abstract: ABSTRACT       Relatively high molecular weight, fiber-forming, crystalline copolymers of lactide and glycolide are prepared in a two-stage polymerization process.  In the first stage there is prepared a random copolymer of a major proportion of an opti-cally active lactide with a minor proportion of glycolide or d,l-lactide.  In the second stage, a major amount of glycolide and a minor amount of lactide monomers are admixed with the co-polymer of the first stage and the polymerization resumed until there is obtained a high molecular weight addition copolymer of lactide and glycolide containing from about 50 to 75 wt percent of units derived from glycolide.  The polymer is fiber-forming and useful in the preparation of absorbable surgical sutures.

Abstract: ABSTRACT OF THE DISCLOSURE           A bicycle having front and rear wheel caliper brakes connected by cables to a plate member rockably mounted on a support rearwardly of the crankshaft; there being a latch arm engaged to said plate and having a cam follower portion for engaging a cam formed on the edge of a disc cam keyed on said crankshaft for mutual interengagement upon back pedaling action whereby said latch arm is translated rearwardly with consequent rocking of said plate member to apply a rearward pulling upon said cables for braking of the bicycle.  A drive sprocket is carried upon the opposed end of said crankshaft for limited relative movement with respect thereto, there being an arcuate aperture in said drive sprocket receiving a pin from the adjacent pedal crank, which pin is relatively movable within said aperture so that after braking action said crankshaft may be rotated a predetermined distance prior to engagement of the finger with the forward end of the aperture for consequent concurrent rotation, said predetermined distance being adequate for disengaging said latch arm for brake releasing action.  The brake release aspect of this invention may also be used with bicycles having front free wheel systems wherein an arrangement of intermeshing teeth are provided on the drive sprocket and a sleeve to allow for requisite relative movement.

Abstract: ABSTRACT     A wire stitcher for binding sheets into sets in which cut lengths of wire are formed into staples about an anvil 104 by a former 105 and the formed staples are driven by a driver 106. The wire W is gripped against the anvil 104 by the driver 106 during forming and the staple is supported with the aid of the anvil 104 during driving.  The driver 106 has a two-stage action in which a first stage motion operates to grip the wire W against the anvil 104 during forming, the driver motion being arrested during forming, and a second stage motion acts following forming to effect driving.  The movement  of  driver  106 and former  105  is  effected by a continuous travel of an input lever.  (Figure 5).
