Title: Improvements relating to the feed mechanism of slicing machines
IPC: B26D7/06
Filed: 1923-06-21
Abstract: 222,183. Thomas, H. June 21, 1923. Cutting slices in succession. - In slicing- machines having a feed-table moved forward step-by-step by a feed screw and segmental nut which is adapted to be moved rectilinearly into and out of engagement with the feed screw by means operated from the front of the feed table, as in Specification 11559/13, these means are wholly carried by and underneath the feed table in such a manner that the table can be readily removed without dismounting the feed-operating mechanism. The sliding movement of the feed table is effected as a continuation of the same manual movement which disengages the segmental nut from the feed screw. A handle 23, Fig. 6, is provided on a disc 22 screwed at 25 to the feed table and capable of limited rotation determined by a set screw 28 engaging a slot 27. A V-groove 26 in the disc may be engaged by a ball 21 provided in a recess 20 in the feed table and engages one end of a rod 18, the other end of which is attached by a link 16 to a pivoted wiper 14 capable of raising the segmental nut 1, Fig. 3, from engagement wi.th its screw 6. The nut is integral with a spring-pressed member 2 sliding in a casing 3, forming part of a bracket which is secured to the back of the feed table.

Patent GB-1018083-A (GB)
Title: Improvements in or relating to electrical timing devices
Inventor: ILLINGWORTH LEWIS
IPC: G08G1/08
Filed: 1961-05-04
Abstract: 1,018,083. Road-traffic signals. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. April 3, 1962 [May 4, 1961], No. 16146/61. Heading G4Q. [Also in Division H3] In a Miller integrator timing circuit for use in a road-traffic signalling system, the capacitive feedback path between the collector and base of a first transistor comprises the base-emitter path of a second transistor connected to function as an emitter follower. In the circuit of Fig. 2, Miller feedback from the collector of transistor TX2 to its base through emitterfollower TX1 is initiated by changeover of contacts X1, X2, capacitor C then charging negatively until the potential at the base of transistor TX3 goes positive with respect to earth, transistor TX3 then conducting and releasing differentially-energized relay Y. Capacitor C is normally discharged through resistor R4; a timing cycle is started by the change-over of contacts X1, X2 whereupon charging current for the capacitor C through resistor R1 causes transistors TX1, TX2 to be switched on, the fall of potential at the collector of transistor TX2 switching transistor TX3 off. C charges negatively until transistor TX3 conducts whereupon further charging ceases since the collector of transistor TX2 is then clamped at earth potential by transistor TX3. Transistors TX1, TX2 are consequently switched off and C remains charged to a fixed value until contacts X1, X2 are released whereupon it is discharged through resistor R4. By virtue of the further stage TX1, the charging rate for the capacitor C, even for long delays of the order of 10 seconds, can be made substantially independent of leakage current fluctuations in the transistor TX2. In a modified circuit, Fig. 3, the delay introduced may be made dependent upon the rate at which vehicles pass. In this circuit, the capacitor C is not discharged at the beginning of the timing interval but is charged to a voltage having a value between those established by the tapping points on potentiometers RC, RD. At the end of a timing interval when contacts X1, X2 are released the capacitor C is discharged through diode DA to the potential determined by potentiometer RD. Thereafter each arrival of a vehicle at a traffic signal showing " Red " causes momentarily operation of a contact X, thus partially discharging capacitor CA, the charge on which capacitor subsequently discharges through resistor RB. The state of charge of capacitor C thus depends upon the number of actuations of contact Z; however, it is prevented by conduction through diode DB from discharging below a level determined by the setting of potentiometer RC. Hence upon a subsequent actuation of contacts X1, X2 the time taken for capacitor C to charge to a voltage causing transistor TX3 to be switched on depends upon the number of previous actuations of contact Z.

Title: Automatic means for rendering a machine inoperative
Inventor: BULGIN DOUGLAS
IPC: F16P3/14
Filed: 1950-06-30
Abstract: 700,751. Detecting presence of objects ; magnetic tests. DUNLOP RUBBER CO., Ltd. June 21, 1951 [June 30, 1950], No. 16345/50. Class 37 [Also in Group XXIV] In a safety device for rubber mixing mills and other machines the machine is switched off when an operator or tool is in a dangerous position by magnetic detector means, adjacent the dangerous parts, which are influenced by permanent magnets attached to the operator's limbs (e.g. by a ring or glove) or by the field surrounding magnetized tools. The detectors 6 are arranged in pairs 3a (or alternatively in threes) with their axes mutually perpendicular and each comprises a cylinder of paramagnetic material having a ring winding 9 energized by an oscillator 10 and a detecting winding 7 around the cylinder so that in the absence of an external field substantially no e.m.f. is induced in the winding 7. But since the permeability of the material is varying (at twice the energizing current frequency), upon introduction of an external field an alternating e.m.f. is induced in the winding 7 which increases as the source approaches and at a pre-detertnined value is sufficient, after amplification, to operate a relay 12 to stop the machine. The amplifiers 4, 5 may be electronic or magnetic. The invention may be applied to a lathe to prevent starting while a magnetized chuck handle is in position, or to a machine where two relatively movable elements must not come within a predetermined distance of each other. According to the Provisional Specification, the amplifiers operate two relays, one of which applies a brake while the other disconnects the power. There is also described a magnetic amplifier consisting of an iron ring having an input winding, an output winding and a power-supplying winding.

A lock comprises a casing 10, 11, 12, 14 and 15, a bolt 18 slidable in the. casing and one or more tumblers 41 within the casing serving as abutments in the path of the bolt to prevent movement of the boll to the unlocked position, the tumbler or tumblers being movable out of the path by the operation of a key,; the lock being characterised in that the tumblers are guided for movement transverse to that of the bolt, the bolt having .a projection 27 which slides along a slot 46 in each tumbler when the slots are aligned i.e. in the unlocked position, the tumblers and bolt being arranged so that in the locked position of the bolt the tumblers are positioned behind the projection and the rear end wall 12 is positioned immediately behind the tumblers to hold the bolt in the locked position. The movement of the bolt is guided by a lug 20 on the bolt sliding in a slot 19 in the back plate 10 and studs 21, 22 on the back plate sliding in slots 23, 24. The bolt is thinner behind the head 17 and has a rearwardly extending rectangular projection 27 of the same thickness as the head with a projecting ear 28 at one end. A roller follower 30 rides on a cam 29 to operate a micro-switch 31 when the bolt is extended and retracted. A turntable 36 with a key-hole 37 is mounted for rotation on the back-plate 10 and projecting from the turntable is a boss 38 which normally engages a groove 39 in a spring 40 but when the turntable is rotated the boss 38 engages a notch 35 in the bolt to slide it along. In the embodiment described there are five tumblers 41 with slots 42, 43 for sliding movement along studs 21, 22 and urged towards the turntable by springs 44. There is a notch 47 in the uppermost tumbler which engages the ear 28 when the bolt is retracted. A depression 60 is provided in the two lower tumblers to jam, the key when in the locked position the key is again turned in the locking direction.

Abstract: 254,742. I.G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister. Lucius, & Br³ning). July 2, 1925, [Convention date]. Isodibenzanthrone dyes are obtained by treating with alkaline condensing agents the aminohalogenbenzanthrones obtainable from nitrated Bz1-halogenbenzanthrones. The nitrated Bzlhalogenbenzanthrones are probably the 6-nitro- Bz1-halogen compounds since they yield nitroanthraquinone-1-carboxylic acids upon oxidation. according to examples, amino-Bz1-chlor, or amino-Bz1-brom-benzanthrone is treated with alcoholic caustic alkali; the product dyes cotton in reddish-grey to black tints, which assume a green hue on chlorinating; it therefore differs from nitrated violanthrone or isoviolanthrone (see Specification 23052/10).

Title: Improvements in or relating to fire or heat detecting devices
IPC: H01H35/24
Filed: 1945-06-30
Abstract: 600,486. Thermal switches ; switch contacts. FARMER, R. B. June 30, 1945, No. 16687. [Class 38 (v)] In a device for actuating a fire alarm or extinguisher, two chambers are interconnected by a restricted aperture, one of the chambers being joined to a vaporizing-liquid filled detector, such that a rapid increase in temperature adjacent the detector causes actuation of a pressure-sensitive device, and thus operation of the alarm, whereas a gradual increase in temperature allows the liquid to seep through the aperture and equalize the pressure on both sides of the pressure-sensitive device. In Fig. 1, the detector element, which may be a copper tube with a <1>/16 inch bore, is joined to a ferrule 37 so that a rapid increase in temperature causes a rapid expansion of the liquid in a chamber 31. As the passage of the liquid to a chamber 32 is throttled by an aperture 30, a diaphragm 8 moves a pin 13 and closes contacts 18, 22 in the alarm circuit, the contact 22 being adjustable by a screw 23. With a gradual increase in temperature, the liquid seeps through the aperture 30 into the chamber 32, whereupon a diaphragm 9, which is weaker than the diaphragm 8, moves down on to a stop 12 so as to equalize the pressure in the chambers 31, 32. The system is filled with liquid through a hole 33 closed by a plug 35. In Fig. 3, rapid expansion of the liquid in a chamber 45A having a diaphragm 48A, causes a spring-plunger 52A to move a spring-controlled arm 58A, and close contacts 61A, 62A, whereas with a gradual expansion the liquid also acts through an aperture 67A on a diaphragm 46A, so that an arm 57A moves with an arm 58A. In order that the system may again function after a fire, when some of the liquid may have permanently changed into a gaseous form, an aircell 71 is provided, and comprises inlet and outlet valves 72, 73 which relieve any excess pressure in the chamber 44A. The aperture may include or be byepassed by a non-return valve to effect a more rapid return of the liquid to the chamber 45A. In Fig. 4, a housing 74 is divided into two interconnected chambers 79, 80 by a diaphragm 78, movement of which is limited by wire frames 90, 91. The operation of the device, which includes an air-cell 89, may be tested by a heating-element 95. In Fig. 5 (not shown), rapid expansion of the liquid in a cylinder moves a piston against a spring to close a pair of contacts, but on gradual expansion the liquid seeps past the piston. According to the Provisional Specification, the liquid may be an ethylene glycolwater mixture.

Filed: 1928-06-11
Abstract: 292,084. Tecalemit, Ltd., (Assignees of Soc. Anon. des Etablissements TÚcalemit)- June 9, 1927, [Convention date]. Actuating by Liquid pressure; single-acting bucket pumps. -In a lubricating system for motor-vehicles and the like, supplied by a pump, a distributing device comprises concentric pistons 4, 5, Fig. 1, of different strokes, mounted in a casing 1, the piston 4 comprising a cupleather mounted on a shouldered tube 6 which is normally pressed upwards by a spring 7, while the piston 5, which is arranged within the tube 6, is formed with a valve 10 at its upper end which normally closes an inlet orifice 11 communicating with the supply 14 and is provided with a collar 5<1> adapted, to rest on a flanged reinforcing sleeve 3 arranged within the cup-leather 4. The piston 5 below the collar 5<1> is of less diameter than the bore of the tube 6 and is terminated by an enlarged part formed with helical threads 5<2> fitting in the tube 6. A transverse channel 5<3> at the base of the piston 5 ensures that the space below the piston 4 is always in communication with a discharge passage 9. Alternatively, the threads 5<2> may be formed in the tube 6. Lubricant supplied through the pipe 14 depresses the pistons 4, 5 until the piston 5 abuts against the base 8, while the piston 4 continues its downward movement until the tube 6 abuts against the base 8, lubricant contained below the piston 4 being thus ejected through the passage 9. When the pump pressure is relieved, the piston 4 is moved upwards by the spring 7, lubricant passing from the space above the piston to the space below through the helical channel formed by the threads 5<2>. When the piston 4 nears the upper end of its stroke, it engages the collar 5<1>, thus raising the piston 5 and closing the valve 10.
