Abstract: A package comprises a cover closing an article housing formed in a baseplate. A contiguous compartment closed by a plate contains a spring assembly comprising two arc members joined at their ends and bearing on abutment members. A profiled rod inserted through a complementarily profiled opening pushes on thrust member against the abutment of the ends of the spring assembly on the abutment members so as to bring about, by symmetrical reaction, retraction of the bar supporting the bolt members. However, if a fly-weight has not previously been retracted by a magnetic field a projection engages in a groove in the fly-weight to lock the lock. The consecutive action of the magnetic field and the pressure on thrust member are applied by a key device retained at the checkout of the self-service store. The invention has one particular application in the merchandizing of prerecorded magnetic tape cassettes.

Abstract: ABSTRACT OF THE DISCLOSURE The invention is a method for making sheeted wood pulp which may later be readily milled or shredded to form an absorbent fluff product. An unrefined wet chemical wood pulp furnish is treated with gaseous ammonia under moderate pressure. Preferred conditions are about 20-40% consistency at pressures of at least 350 kPa for 20-60 minutes. The bulk of the ammonia is then flashed off and the remainder removed by washing. Agitation during the treatment step is desirable. The product is then sheeted without refining. Treated sheets have low power requirements during shredding. Absorbency of the resulting fluff is not adversely affected as it is with normal cationic debonding agents.

Abstract: ABSTRACT:           In a digital demodulation circuit for a chromi-nance signal of a colour television signal comprising a first digital oscillator (35) for producing reference signals and a phase control loop (29, 17, 19, 49, 43) therefor, there is added in the phase control loop a sig-nal combination (at 56) which is obtained from a phase control loop (67, 63, 59) of a second digital oscillator (77).  This second digital oscillator derives the sampl-ing frequency for sampling the chrominance signal from a signal source (83) of a constant frequency and couples this sampling frequency to the horizontal deflection frequency.  By the said addition in the phase control loop of the first oscillator, variations in the horizon-tal deflection frequency cannot lead to the undesired phenomenon of the first digital oscillator being pulled to a side-band frequency of the colour subcarrier wave.

Abstract: A B S T R A C T     A packer for isolating sections of boreholes, to facilitate multilevel groundwater monitoring in a single borehole, is disclosed. The packer includes a water-expandable substance installed in sleeve-like fashion around a casing in the borehole, and covered by an expandable membrane. Holes are provided in the casing behind the water-expandable substance, so that when the casing is filled with water, water flows to the substance, the substance expands, and the membrane is pressed against the borehole wall, thereby effecting a seal to isolate the desired section. The use of a number of packers within a borehole, either singly or in pairs, is contemplated. Instead of being installed directly around the casing, the packers may be conveniently installed around lengths of pipe which are subsequently spliced in with lengths of the casing pipe. The preferred water-expandable substance is a sealant proprietary to the Dow Chemical Company and sold by them under their trade mark DOWELL, but bentonite clay or other suitable water-expandable substances are also contemplated.

Abstract: ABSTRACT          A device for introducing dosed or proportioned quantities of pulverized solid materials into a carrier gas stream is presented.  The device comprises a housing which defines a flow chamber in the axial direction for the flow of pressurized fluid or carrier gas.  The housing also has a side aperture there through.  The side aperture is connected to a container holding pulverized materials.  Coaxial inner and outer sleeves, at least one of which is capable of rotation, are located within the housing.  The outer sleeve communicates with the aperture while the inner sleeve has an axial bore which provides a passage for the carrier gas.  Upon rotation of a sleeve, slots provided on each sleeve will align and overlap with each other and with the aperture to define a variable sized passage between the container and axial bore whereby the pulverized material is delivered there through to the carrier gas stream.  A third sleeve which is coaxial with the inner and outer sleeves and rotatable about its longitudinal axis is located between the housing and the outer sleeve.  This third sleeve has a radial aperture corresponding to the side aperture of the housing.  The third sleeve acts as a valve between the dosing device and a distribution tank.

Abstract: ABSTRACT OF THE DISCLOSURE     According to the present invention an electrical conductor assembly is possible, which is less expensive to produce and ship while improving in the quality thereof.  This is achieved by using synthetic foam fillers between electrical conductors which are of reduced weight and achieve their resiliency through the closed gas cells.  In some applications, the synthetic foam is reinforced with a polymeric yarn to increase the tensile strength needed in the manufacture of large diameter conductor assemblies.  The foam fillers readily conform to the shape of the interstices between electrical conductors when compressed by an exterior type member.          Therefore, it is possible to use a single foam filler to replace the many strands of polypropylene fibres or twine fibres formerly used, and the foam filler will readily deform to the required shape to essentially completely fill the interstice between conductors.  Superior resistance to water contamination is achieved as the closed cells of the foam eliminate "wicking" of water within the filler which is a problem with stranded fillers.

Abstract: Abstract of the Disclosure A multiple alert pager has: a radio receiver for receiving a carrier wave modulated with at least a paging signal and demodulating the carrier wave; a decoder for comparing a demodulated carrier wave with a self alert code and generating an alert signal when a coincidence between the demodulated carrier wave and the self alert code is found; a plurality of alert means for paging a user in response to the alert signal; and a reset switch for stopping the alert signal, wherein the decoder switches among the plurality of alert means upon a first operation of the reset switch.     Specification Title of the Invention Multiple Alert Pager Background of the Invention The present invention relates to a pager and, more particularly, to a multiple alert pager for selectively generating alert signals by a plurality of alert means such as an audio alert means for generating an audible alert tone at a loudspeaker, a visual alert means for generating a visual alert signal to turn on an LED, and a vibration alert means for generating a vibration alert signal to drive a motor, and so on.        In conventional pagers of this type, when a user is paged or called, he must set a switch at a desired position to determine whether audio and visual alert means are simultaneously operated or one of the audio and visual alert means is operated. In this multiple alert pager, the switch must have the number of contacts which corresponds to the number of combinations of the alert means, resulting in an increase in size of receiver. Summary of the Invention It is a principal object of the present invention to provide a pager having a plurality of alert modes without an increased number of contacts.        It is another object of the present invention to provide a compact multiple alert pager with good

Abstract: ABSTRACT     MANCHESTER DECODER    A decoder for Manchester encoded data signals in which the encoded  data  signals  are  applied  to  a  first  circuit  which produces  a  primary  pulse  at  each  voltage  transition  of  the applied  signals.    The  primary  pulse  enables  a  delay  line oscillator which after a predetermined period of delay produces a decode clock signal of a given frequency.   The inverted primary pulse, the decode clock signal, and a constant voltage data input signal are applied to a decoder  shift register.   The primary pulse and selected outputs  of  the  decoder  shift  register  are applied to a logic circuit which produces a receive clock signal having   desired   low-to-high   voltage   transitions   occurring substantially in the center of each half-bit cell of a Manchester bit cell.   The receive clock signal can be applied to a receive data shift register to which the encoded data signals are also applied so that the binary value of  each half-bit  cell  of  a Manchester bit cell can be stored in the data shift register.
