Abstract: 1,234,077. Razor blade dispensers. WARNER - LAMBERT PHARMACEUTICAL CO. 23 May, 1968 [23 May, 1967], No. 24660/68. Heading B8P. A plastics &c. razor blade dispenser comprises a sleeve A into which a blade carrier B is inserted. The carrier B, Fig. 7, consists of a platform 3 having two enlarged end portions 4, 5 the first of which abuts end edges of the sleeve A and the second of which has spaced apart lugs 7a defining with the top wall of sleeve A a blade exit slot 8 normally closed by a cross-bar 18 connecting two resilient tongues 11a. A guide rib 13 on a resilient tongue 12 enters slots D in a pile of blades and in combination with lugs 14 holds the pile in position. The uppermost blade in the pile is pushed forward by insertion of the thumb through an opening 17 in the sleeve A. Downward deflection of the tongue 12 as the uppermost blade advances permits the latter to slide over the rib 13. As the leading edge of the blade is slid up the surface 19 on the crossbar 18 towards the exit slot 8, the cross-bar is deflected downwardly to permit the blade to pass through the slot. The carrier B latches into the sleeve A and the latter has an opening (23), Fig. 3 (not shown), into a compartment for used blades. The carrier B can be released from the sleeve and reloaded.

Abstract: 1,250,242. Capacitors. WELWYN ELECTRIC Ltd. 26 March, 1970 [27 March, 1969] No. 16180/69. Heading H1M. A capacitor is manufactured by applying a layer of a cermet capable of becoming electrically conductive on firing and containing at least 3% glass to a layer of nickel or a nickel alloy and firing the two layers to render the cermet layer electrically conducting and to form the capacitor dielectric by chemical reaction between the nickel or alloy layer and the cermet, the cermet having a lower melting point than the nickel or alloy layer and the proportion of glass being insufficient for the specific resistivity of the cermet to exceed 10<SP>6</SP> ohm-cm. Such cermets are stated to be well-known and specific cermets are identified by their trade designations. The alloy may contain boron, phosphorus or phosphorus and cobalt. The nickel or alloy may be a sheet or deposited on a substrate, e.g. by electroless plating. The cermet may be applied by screen printing and a further conductive layer may be applied by vapour deposition to make electrical contact to the cermet layer. The nickel or alloy layer may be so thin that the part covered by the cermet reacts completely, the capacitance then being between the edges of the uncovered part and the cermet. In -this arrangement the electrodes may be interdigitated.

Abstract: 1,250,414. Silicon-containing sulphenyl chlorides; polymer derivatives. ESSO RESEARCH & ENG. CO. 31 Jan., 1969 [9 Feb., 1968], No. 5413/69. Headings C3P and C3S.  Silicon-containing sulphenyl chlorides which react with unsaturated polymers to produce moisture-curable polymers have the formula where n is 0 to 12, R 4  is a hydrolysable group, R 5  and R 6  are the same or different C 1-6 alkyl groups or hydrolysable groups and A is: (a) -CR 1 R 2 C(Cl)(R 3 )- where R 1 , R 2  and R 3  are the same or different and are H or C 1-6  alkyl, (c) a divalent C 4-12  cycloalkane or cycloalkene radical substituted by a C1 atom or a carbon atom adjacent to the one attached to the S atom. They are prepared by two methods: (1) reacting a hydrolysable silane containing an unsaturated hydrocarbon radical with SCl 2 ; (2) reacting such a silane with S 2 Cl 2  to produce the bis-sulphur adduct and then halogenating. When the hydrolysable groups in the products are halogen, they may be converted to alkoxy or carboxy groups. The SCl group may also be converted to SOOCR, SOR, SSCN or SNCS.  The compounds are mixed with polymers containing at least 0.5 mol per cent unsaturation in amounts of 0.5 to 50% by wt. of the polymer. A diluent may be used to dissolve the polymer. Reaction is effected in an anhydrous atmosphere. Suitable polymers are isobutylene-isoprene or -piperylene copolymers which may be halogenated, styrene-butadiene copolymers, polybutadienes, polyisoprenes and optionally halogenated terpolymers of ethylene, propylene and a diene. The resulting moisture-curable polymers are preferably stabilized by the addition of a compound of the formula RC(OR<SP>11</SP>) 3  or R<SP>1</SP>RC(OR<SP>11</SP>) 2  where R and R<SP>1</SP> are H or C 1-4  alkyl and R<SP>11</SP> is C 1-4  alkyl, e.g. ethyl orthoformate. They may also be converted to a latex by subjecting the polymer in a hydrocarbon diluent, preferably containing a stabilizer, to a water-alcohol wash, emulsifying, adjusting the pH to 6 to 8, and stripping off the diluent in water while adjusting the pH to 4 to 7.

Abstract: 1,252,839. Regulating switches. E. SCHEUBECK. 5 Sept., 1969 [14 Sept., 1968], No. 43993/69. Heading H1N. To reduce the lateral dimensions of a tap changer having a change-over switch for reversing the polarity of the tapped regulating winding with respect to the main transformer winding (thereby doubling the regulation obtainable with a given number of taps) and wherein the fixed contacts of the tap selector are secured on vertical insulating bars in a cylindrical arrangement, the three fixed contacts of the change-over switch are also mounted on vertical insulating bars arranged in the same cylindrical path. Fixed selector contacts, such as 5, 6, of the three phases U, V, W, are arranged on vertical bars 21 to lie on circular paths with even-numbered contacts 2 to 12 co-operating with wipers 24 and odd-numbered contacts with wipers 23. A drive wheel 41 alternately steps Geneva wheels 42 and 43 coupled to wipers 23 and 24 respectively. The spacing of the end contacts (such as 2 and 12) from the mid-value contact K (which is connected to the main winding) is greater than the mutual spacing between the tap contacts to allow for the greater voltage difference, and the wheels 42 and 43 have funnel-shaped slots (44, Fig. 7, not shown) providing the smaller steps and straight slots (45) providing the two larger steps. In the larger spaces between bars 21 supporting contacts K and contacts such as 2 and 12, further bars 28 are fitted and carry outwardly-projecting change-over contacts + and - connected by leads 37 to the ends of the regulating winding. Insulating bars 32 carry arcuate bridges 30 and are pivoted concentrically with selector column 27 by means of arms 34, 35. A dog 46 on Geneva wheel 43 engages in and moves a slotted arm 49 on completion of a revolution of wheel 43, and a dog 49 on arm 34 couples this movement to the bridges 30 which are thus moved (as the wipers 24 engage the contacts K) to interconnect contacts K with the + contacts instead of the - contacts, or vice versa, whereby on completion of a tapping sequence the relative polarity of the regulating winding is reversed.

Abstract: 1,256,816. Electric selective signalling. BECKMAN INSTRUMENTS Inc. 3 March, 1970 [1 April, 1969], No. 10059/70. Heading G4H. [Also in Division H2] An overspeed detection system for a rotating device such as a centrifuge comprises counters 20, 21 for counting the number of pulses produced by the revolutions of the device in a given time interval and a circuit for determining whether this number is greater than or equal to the sum of a pulse count representing a desired speed of the device and an additional pulse count representing an allowable overspeed. The time interval of one tenth of a second is established by a pulse generator 16 which supplies reset pulses R to the counters 20, 21 and to flip-flops 24, 27, 30. A photo-detector supplies pulses representative of the speed of the centrifuge to the counter 20, one pulse per second corresponding to ten r.p.m. of the centrifuge. The output of the counter 21 increases by one for every ten pulses received and is fed to a decoder 22, the outputs of which represent 11,000 to 20,000 r.p.m. An arm 36 of a speed selector switch 37 is initially set at the terminal corresponding to the desired speed, for example 11,000 r.p.m. In one tenth of a second 110 pulses will be counted, a NOR gate 25 being primed at its input A when the count reaches 100 due to the output signal from terminal '0' of the decoder 22 and being opened when the count reaches 110 due to the output signal from terminal '1' of the decoder. A NOR gate- 31 is therefore primed at its input B so that if the speed of the centrifuge now increases such that the count reaches 114, the '4' output from the counter 20 will open the gate 31 and cause a latch circuit 32 to activate a time delay 34 thereby initiating a five-second timing period. If the overspeed condition persists for more than five seconds a circuit 35 is activated and the centrifuge power is removed. If during the five seconds period the speed of the centrifuge falls, an unlatch circuit 33 resets the latch circuit 32 to disable the delay 34 and allow the centrifuge to continue to operate.

A method of producing, after the appearance of a release signal at an arbitrary time, a single pulse corresponding in time with a single field of a television signal, comprises generating a pulse 6, from the release signal, having a duration slightly longer than the picture period, suppressing alternate ones of the field pulses 1 so as to form a series 3 of synchronizing pulses, generating a second rectangular pulse 11 upon coincidence of a synchronizing pulse with the first rectangular pulse and releasing the required single pulse 16 by the trailing edge of a pulse 13 which occurs during coincidence of the second rectangular pulse 11 and the next synchronizing pulse 3. As shown in Fig. 1, alternate ones of the field pulses 1 are suppressed in a frequency divider 2 and the resulting pulses 3 fed to an AND gate 7 together with the first pulse 6 generated in a monostable multivibrator 5 on receipt of a release signal 4. The remainder of the circuit includes negators 9, 14, monostable multivibrators 10, 15 and AND circuit 12. NOR logic may alternatively be employed.

Abstract: 1,259,141. Programmed control of machine tools. HUGHES AIRCRAFT CO. May 23, 1969 [June 10, 1968], No.26557/69. Heading G3N. A milling machine is controlled along three axes in accordance with data derived from a programming device providing pulses in the form of words in binary coded decimal which are converted to conventional binary words. A unit 16 stores the input data pulses until a signal transfers the content to an axis motion interpolator such transfer signal being supplied by the tape in the form a binary word. A generator 20 provides a feedrate signal to the interpolator, each of the interpolated words being applied to an axis command counter. The latter is coupled to a phase detector providing data to a servo driver associated with a motor which drives the machine tool along an appropriate axis. The programming device produces feedrate and distance-to-go signal, the interpolator comprising a first integrator 141 receiving the feedrate signals and a second integrator 72 receiving the distance-to-go signals and controlled by the first integrator, for controlling the servo device. A circuit responsive to the feedrate signals is coupled to both integrators for increasing the frequency of one while decreasing that of the other. This circuit comprises the register 16, a counter 58 driven at a constant pulse rate, and means for comparing the outputs of these units for controlling the frequency of the integrator 141. A scaling register 64 responds to the register 16 and its output is compared with that of the counter 58 for controlling the output of the integrator 72. The integrators 141, 72, each include an integrand register 42, 74, receiving either the feedrate or distance-to-go signals, an accumulator register 48, 84 and an adder 46, 82, for adding the contents of the integrand register to the accumulator register. The generator 20 is coupled to the adder 46 for controlling the rate at which the registers 42, 48, are combined, a switching circuit coupling the integrator 141 to the adder 82 for controlling the rate at which the contents of the registers 74, 84, are combined. A register 78 receives the distance-to-go signal, a stop signal being generated when the output of the integrator 72 bears a predetermined relationship to the distance-to-go signal.

A process for the continuous and selective catalytic partial hydrogenation of unsaturated organic compounds which in the liquid state are mixed with a catalyst and successively recirculated in a plurality of stages, comprises, during each recirculation 18, Fig. 1, the step of generating in the reaction mixture by an injector 5, great shear forces of short duration to partially or completely eliminate the hydrogenation of the compounds to saturation, and the step of supplying the reaction mixture in the injector with adjustable amounts of hydrogen, the velocity of recirculation and the temperature of each stage being separately adjustable. The hydrogen is sucked into injector 5 from chamber 12, which chamber is controllably supplied by recirculation conduit 21. Fresh hydrogen is controllably fed into the reactor 1 from conduit 15. The process may be applied to the partial hydrogenation of straight chain fatty acids e.g. fish oil, to obtain margarine fats.

After a given angle of rotation of star wheel 4, a stop 22 restraining the rotor 16 is released so that the rotor 16 is rapidly rotated by the spring 18 and a projection 32 thereof catches up with an angularly adjustable synchronizing lever 30 on the shaft 14 to drive the shaft 14 and hence the star wheel 4 during the final few degrees of the limited angular movement initiated by tappet 2, 3. The star wheel 4 thus actuates cam follower contact springs 10, 11 and the rotor 16 actuates a cam follower contact spring 28 so that the respective contact sets are synchronously actuated in the final few degrees of the movement. The movement of the rotor 16 is arrested by the stop 22 co-operating with a projection of the rotor. As shown, the rotor 16 has a series of projections in a recess which are arranged alternately nearer and farther from its axis. The stop 22 is reciprocated in response to rotation of shaft 14 by the co-operation of rotary discs 25, 26 carried by a plate 23 carrying the stop 22 with a cam 24 carried by the shaft 14. The spring. 18 instead of being wound up through gears 12, 13 by star wheel 4 may be wound up by the clock mechanism (not shown).

FS4 operating in the thickness shear mode, each structure consisting of a piezoelectric wafer 14, 48, 50 or 52 and each wafer forming two resonators by means of two pairs of electrodes. Thus, wafer 14 has electrode pairs 10, 12 and 18, 20 forming resonators 16, 22. The two resonators of each -structure FS1 ... FS4 are "control coupled" by means of the respective piezoelectric wafer and each structure is so dimensioned that the two resonators are more loosely coupled than the maximum "controlled coupling condition". "Control coupling" means that the two resonators affect one another by only a small controlled degree and the loosely coupled condition ensures that F A -F B  is less than the maximum Fa A -F A  or Fa B -F B , where F A , F B  are the resonant frequencies of the two resonators and Fa A , Fa B  are their antiresonant frequencies. Similarly, the resonators of the adjacent structures FS1 ... FS4 are loosely coupled by a degree less than the maximum controlled coupling condition by means of a capacitor. Thus, resonators 22, 54 of structures FS1, FS2 are coupled by a capacitor C1, the structures FS2 ... FS4 being similarly coupled by capacitors C2, C3. According to another embodiment (Fig. 18, not shown), four coupled monolithic crystal structures have, respectively, five, three, two and three resonators. In another embodiment (Fig. 19, not shown) the coupling capacitors are replaced by inductors. The Specification gives an analysis of the circuit and also a synthesis.
