Title: Improvements relating to slicing machines
IPC: B26D7/06
Filed: 1929-12-03
Abstract: 343,626. Slicing-machines. F I TZ - PATRICK, H. D., 94, Hope Street, Glasgow. -(Naamlooze Vennootschap Maatschappij tot Veraardiging van Snij machines Volgens van Berkel's Patent en van Andere Werktuigen; 33, Boezemsingel, Rotterdam, Holland.) Dec. 3, 1929, No. 36935. [Class 28 (ii).] In a slicing-machine of the kind having a feed table guided at one side by " narrow guide mechanism," the movable guide element carries a brake-member which engages the stationary guide element to prevent irregularities in the feed movement due to wear of the feed nut. As shown the invention is applied to a machine as described in Specification 294,418, [Class 28 (ii), Kitchen and like appliances &c.]. The feed-nut segments are carried on pivoted arms having rollers 9 which engage in cam grooves 10 in the sliding member 11, 12, so that when the member 11, 12 is moved to the right, Fig. 1, by means of the pin 14 engaging the handle 13, the segments are engaged with the feed screw, and vice versa. The narrow guide comprises a saddle 5 straddling a stationary bar 4, the saddle being connected at 6 to the feed-table and is detachably secured thereto by a latch having a handle 7. The brake consists of a pad 16 shaped to fit the bar 4 and having a steel or like wear plate 20 against which the cam 17 presses. The cam is a rotary member having a flat 17a and a lever arm 19 which is acted upon by a compression spring 21. When the member 11, 12 is slid to the left to release the feed nut segments, the projection 22 on the member engages the arm 19 and moves it against the spring action, thus bringing the flat 17a against the plate 20 and releasing the brake. The feed table is then free for hand adjustment. When the member 11, 12 is moved to the right to re-engage the segments, the projection 22 releases the arm 19 and the spring brings the brake into action. The projection 22 may be formed on the lever 13 instead of on the member 11, 12, and an eccentric may be used instead of the flatted cam 17. Specification 294,419, [Class 28 (ii), Kitchen and like appliances &c.], also is referred to.

Abstract: 796,517. Linear dimension gauges. CENSOR PATENTUND VERSUCHS-ANSTALT. Dec. 28, 1955 [Dec. 31, 1954], No. 37057/55. Class 106 (2). [Also in Group XXXVII] The contacts 13 ... 15 of the gauging head of a tolerance measuring instrument are connected across bridge circuits each of which becomes balanced when the appropriate contacts close, so that almost immediately the current through the contacts ceases and they may be reopened without arcing (see Group XXXVII). In Fig. 3, the contacts 13, 14 indicating the upper limit are connected through earth across a bridge circuit supplied by a transformer 27 and having as its four limbs impedances 21, 22, cathode resistor 18 and a thyratron 17 in series with the upper limitindicating lamp 20. Similarly, the bridge circuit for the contacts 13, 15 comprises the impedances 21, 22, a cathode resistor 24 and a thyratron 23 in series with the lower limitindicating lamp 26. Initially with the contacts open the thyratrons are non-conducting and the lamps are not lit. Should the contacts 13, 14 or 13, 15 close, then the potential across the impedance 22 is applied to the control grid of the appropriate thyratron 17 or 23 which strikes on the positive half cycles of the supply and lights the associated indicator lamp 20 or 26. As the supply is A.C. the thyratron ceases to fire when the contacts reopen. Fig. 4 (not shown), illustrates a modified arrangement in which lamps indicate undersize, correct size and over size.

[Also in Division H4] An intruder detection system includes two beams of radiation propagated in opposite directions along a boundary to be protected, each end of the boundary being provided with a detector 3, 4 and a comparator 7 for comparing the relative times at which interruption of the beam is detected. As shown in Fig. 1, two light beams are transmitted coaxially by transmitters 1, 2 and the difference in received times of an interruption denotes the position of the intruder along the boundary. The comparator 7 is positioned symmetrically with respect to the detectors to equalize time delays. In a second embodiment Fig. 2 (not shown) only one transmitter is used, the other being replaced by a reflector. The comparator is also situated adjacent one detector, and a delay equalizer is inserted into the connection between this detector and the comparator. In a further embodiment Fig. 3 (not shown) two closely spaced beams are used instead of coaxial ones. Other forms of radiation such as infra-red, ultra violet, microwave, or sonic waves may be used. The signal may be pulsed or continuous.

Abstract: 372,064. Fluid-actuated valves. HELLYER, R. H., 35, Red Lion Square, London. April 8, 1931, No. 10382. [Class 135.] Valves controlled by pilot or relay valves.-A flushing valve of the kind having a piston actuated main valve controlled by a manually actuated auxiliary valve has a dashpot device arranged between the auxiliary valve and its actuating member so that the auxiliary valve can close after a predetermined interval irrespective of the position of the manual actuating mechanism. The main valve 10 is normally held against a seat surrounding, the outlet 7 by inlet pressure admitted through a bleed hole 8 to act on a piston 1, and is opened by venting the pressure in the space above the piston through an auxiliary valve 4. The valve 4 is carried by a cylinder 4a working over a piston 12 and itself fitted with a piston 18 working in a cylinder 13 detachably secured to the casing. When the operating plunger is moved against the action of a spring 5 it acts through a bellcrank lever 19 and cap 12b to depress a spindle 12a secured to the piston 12. This piston acts on a body of water, previously admitted through passages 13b, 15 and non-return valve 16, to depress the cylinder and open the auxiliary valve. On release of the operating plunger the piston and cylinder 4a return to their normal positions under the action of a spring 11. If the plunger is held depressed water escapes irom the cylinder 4a through a bleed hole 17 and allows the cylinder to move over the piston 12 to close the valve 4.

Abstract: 892,919. Transistor amplifying circuits. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 31, 1960 [Feb. 8, 1960], No. 37325/60. Class 40(6). [Also in Group XXXVI] In a bandpass amplifier signals are fed via resistor 11, Fig. 1, into a low-pass filter 13 followed by an amplifier 15 and resistor 17 which applies negative feedback over both amplifier and filter. The effect is to convert the arrangement into a high-pass filter, the output of which is fed via resistor 18 to a further low-pass filter 20 and amplifier 22. The two low-pass filters may comprise structures possessing distributed series resistance and shunt capacitance; in an embodiment each filter comprises a layer 34, Fig. 2, of N-type semiconductor material adjacent a layer 36 of P-type material, forming distributed series resistance. The distributed capacitance comprises a depletion layer 40 formed by reversebiasing the element over resistor 60 and lead 38. The filters are integral with the corresponding amplifiers, each N-type layer being extended to form the base element of a PNP transistor 28, 33, 30. The frequency and bandwidth of the arrangement may be varied by variation of the reverse biases on the two filter elements. In a further embodiment, Fig. 3, a monolithic structure is built up from a single piece of semiconductor material embodying the two transistors, two filter areas 25<SP>1</SP>, 26<SP>1</SP> and resistors 1.7<SP>1</SP>, 11<SP>1</SP> and 18<SP>1</SP>.

Title: Control arrangement for vehcile headlamps
IPC: B60Q1/05
Filed: 1973-08-10
Abstract: 1471652 Control of vehicle headlamps by DC motors LUCAS ELECTRICAL Ltd 18 July 1974 [10 Aug 1973] 37914/73 Headings H2H and H2J The headlamps (not shown) of a vehicle are moved between an extended operative position and a retracted inoperative position when contacts 17, 18 of switch units 10, 11 are operated to continuously energize or de-energize the main beam or dipped filaments 20, 22 and cause energization of motors 13, 14 driving the lamps, the unit 11 having a further contact 24 (ganged to contact 18) operable to briefly energize the filaments 20 and cause normal extension of the headlamps, retraction being delayed, when the contact 24 de-energizes the filaments 20, due to the time taken by a heat sensitive switch to restore to its normal condition, which switch is controlled by the contact 24 and controls the motor supply circuits. In Fig. 1 operation of contact 17 to its lower positions continuously energizes the filaments 20 or 22 according to the position of switch 18 and energizes the coil 33 of a relay 12 whose contact 34 changes over to connect a supply T to motors 13, 14 through contact 36, diodes 47, 50 and the contacts 45, 51 and 48, 52 of respective changeover switches 13a, 14a. At or towards the end of the motor (lamp) movement, the contacts 51, 52 are changed over by the motors to switch them off and engage contacts 39, 51 and 42, 52. The latter pairs of contacts complete energizing circuits for the motors to retract the lamps when contact 17 is restored to its upper position, coil 33 is de-energized- and contact 34 changes over to engage contact 35 and connect supply T to diodes 41, 44 and the aforementioned contact pairs. Subsequent motor movement again changes over the contacts 51, 52. Depression of contact 24 to energize filaments 20 also energizes a heat extensible strip 15 through members 26, 27, 28, 18 and 22 (which are not illuminated) and energizes the relay coil 33 to extend the headlamps in the aforedescribed manner. Normally-closed contacts 16 are opened by energization of the strip 15 and reclose with a time delay when the contact 24 is opened to allow the strip 15 to cool, the lamps thus remaining extended until contacts 16 close to complete the motor supply circuits. Further operations of the contact 24 are thus possible before the lamps are retracted. Malfunction of the switch 15, 16 to cause contacts 16 to be permanently closed or open will respectively produce immediate retraction of the lamps or prevent retraction after extension. The modification shown in Fig. 2 uses a heat sensitive switch 115, 116 whose contacts are normally open and control the coils 133a, 133b of relays 112a, 112b controlling the motors 113, 114 through changeover switches 113a, 114a. Closure of contact 124 energizes the relay coils from supply S through members 126, 153 to extend the headlamps and also energizes strip 115 to close contacts 116. When contact 124 is opened, contacts 116 remain closed for a predetermined time to energize the relay coils from a supply R and so prevent immediate retraction of the lamps.

Abstract: 1,274,457. Sulphur; separating sulphur values from gas streams. RALPH M. PARSONS CO. 1 Aug., 1969 [23 Aug., 1968], No. 38668/69. Heading C1A. Sulphur is removed from a gas containing H 2 S by a process comprising the steps of contacting the gas with an alumina supported oxide of a metal containing 10 to 40% by weight of the metal oxide to form a sulphide of the metal, oxidizing the sulphide to regenerate it to the oxide and to separate the sulphur values from the metal, and cyclically repeating the steps of contacting and oxidizing. The preferred oxide is supported ferric oxide. The supported oxide may be in a fluidized or moving bed which is continuously recycled between a contacting and regenerating zone; The process of the invention may be used to purify the tails gases from a process in which a gas containing sulphur compounds is treated to produce sulphur, e.g. the Claus kiln reaction, any unreacted SO 2  being recycled. The tail gas may beat a temperature of 150‹ to 400‹ C. The process of the invention may also be used to separate sulphur values from gas streams obtained by subjecting carbonaceous materials to partial oxidation and the water gas shift reaction. Plant comprising conventional absorption/regeneration pairs of contacting towers, adapted to perform the process of the present invention insofar as they contain the specified alumina supported oxide are also claimed.
