Title: Locking means for train stops employed on railways and other motor operated apparatus
IPC: B61L7/06
Filed: 1932-03-14
Abstract: 397,573. Track apparatus for stopping trains. BRITISH POWER RAILWAY SIGNAL CO., Ltd., GLENN, S. L., and PIERCE, E. E., Windsor Works, Slough. March 14, 1932, No. 7564. [Class 105.] Apparatus, such as a train stop, having an arm moved from a normal to a reverse position by an electric or other motor driving a pinion which climbs up an arc-shaped rack on the movement of the parts to the reverse position and travels down the rack during the gravity or spring restoration to normal is locked against any external forcible movement of the arm to the reverse position by providing on the pinion a short untoothed portion which lies opposite the lower part of the arc-shaped rack when the parts are at normal and a locking means fixed on the pinion and adapted in the final stage of the return movement to normal to engage with a means in the mechanism casing thereby to prevent upward forcible movement of the pinion ; this looking means is automatically released when the motor is set in motion for the purpose of setting the arm to the reverse position. The Figure shows the relevant parts of a train stop mechanism as described in Specification 286,362, [Class 105, Railway signals &c.], modified in accordance with the present invention. The train stop is moved to reverse, on energization of the motor, by the motordriven pinion 3 climbing up the rack 8 and is returned to normal by the gravity descent of the motor and pinion 3. In the full normal position the pinion 3 presents an untoothed portion 200 to the rack 8 and inserts a cross bar 201 of a stirrup piece 204 beneath a fixed lug 202 so that external forcing of the train stop, which would necessitate the pinion 3 rising, is prevented. On energization of the motor the rotation of the pinion 3 first removes stirrup bar 201 from beneath the lug 202 and thereafter the teeth of the pinion engage the rack 8 to effect the climbing. Any person having authorized access to the interior of the mechanism casing can move the stop manually to the reverse position by a handle 210 on the the stirrup piece 204. The rack 8 is capable of a slight movement and to position it correctly in the full normal condition the stirrup 204 is provided with a second bar 212. An alternative locking means consists of a cheek fixed on the pinion and formed with a cam to engage a corresponding cam on the rack member.

Patent GB-703859-A (GB)
Title: Improvements in and relating to wrapping material for foodstuffs
Filed: 1951-04-04
Abstract: An edible film is reinforced with alginate yarn to form a wrapping material for foodstuffs.  The alginate yarn may be formed into a fabric which is scoured to remove oil and dirt and then passed into a bath of the edible film-forming material and dried. The reinforcement yarn may be of calcium alginate or alginic acid; it may be knitted or woven, or formed into flat sheets which may be cut to the required size and formed into tubes or casings by means of an edible adhesive, preferably of the same composition as the edible film.  The scouring is preferably carried out with an aqueous solution of an anion-active compound, e.g. sodium oleyl p-anisidine sulphonate or a sodium alkyl sulphate.  The edible film may be alginic acid, sodium, calcium or other alginate, a partial glycol ester of alginic acid or its calcium salt, a water-soluble cellulose ether such as sodium carboxymethyl cellulose, gelatine, pectin, albumen or casein.  A non-toxic dyestuff may be incorporated in the reinforcement or the film if desired.  In an example calcium alginate yarn is knitted into a seamless tube of 3 in. circumference and the tube is scoured with aqueous sodium p-anisidine sulphonate.  It is then passed while wet round a roller dipping into a 5 per cent. solution of propylene glycol alginate ester.  After removal of excess solution by nip rollers the tube is passed into 15 per cent. aqueous calcium chloride, washed free from excess calcium chloride in running water and dried, the tube being opened up as it passes into the drying chamber by a ball placed inside it.  The dried tube may be used as a sausage skin.

Title: Pulsator
IPC: A01J5/10
Filed: 1974-02-21
Abstract: 1432092 Pulsator ALFA LAVAL AB 21 Feb 1974 [21 Feb 1973] 8030/74 Heading AIM A pulsator for use in a two-chamber teat cup milking system provides different vacuum time atmosphere time ratios with vacuum change: relatively high vacuum is applied to the liners and pulsation chambers under normal milking and lower vacuum applied at both places when flow is reduced. A magnet float switch is actuated by milk flow and itself effects switching of a circuit to produce the higher or lower vacuum. The pulsator comprises a spindle 37 which imparts a reciprocating movement to two slides 38, 39 only one of which at a time lies against a slide plane into which open a vacuum channel 42 and two pulsation channels 26, 27 arranged on either side of the vacuum channel 42. In the upper part of a connection chamber is a spring 45 which presses slide 39 against the slide plane and lifts slide 38 upwards, when low vacuum prevails in the liners and pulsation chambers. When high vacuum prevails the spring 45 is overcome and slide 38 is pressed against the slide plane. Thus when the spindle 37 reciprocates the channels 26 and 27 alternately receive vacuum each being alternately connected by the connection chamber, while the other is effectively open to the atmosphere. The size and position of the cavities in the slides may be varied to alter the vacuum/atmosphere time ratio. Other embodiments have two or more different ratios (Fig. 7). A single slider 38a with two sets of cavities 69-71 and 72, 73 (Fig. 8) moves at right angles to the plane of Fig. 7 over a plate 41a having an opening 42a leading to the vacuum channel and openings to channels 26, 27. A sheet 61 lies on the plate 41a and is adjustable by means of membrane 62 in housing 63 which is connected to the teat cup lines and hence the prevailing vacuum so that membrane 62 moves when the pressure changes. Sheet 61 has holes 68 punched therein which transversely correspond with the holes in the plate 41a. The variation in size of these holes alters the vacuum/atmosphere time ratio. A milking vacuum stabiliser is provided in the system to ensure that equal vacuo are applied to the two chambers of the teat cups.

Filed: 1974-02-22
Abstract: 1466961 Arbors E D HOUGEN 22 Feb 1974 [26 Feb 1973] 8065/74 Heading B3C [Also in Division B5] An arbor for an annular hole cutter comprises a shank 32 having a rear end adapted to be secured to a rotary driving member 40 and a forward end adapted to support a cup-shaped annular cutter 14 having cutter teeth 58 for cutting a circular groove through a workpiece 12 which simultaneously forms a round slug within side walls of the cutter 14, said shank 32 having a central axial bore 34, a pilot member 42 axially slidable in said bore 34, a spring 70 biased sleeve 60 for holding said pilot member 42 axially outwardly beyond the front end of the shank, said shank having a slot 64 which receives a pin 66 fixed diametrically across the sleeve 60 to limit the axial movement of the sleeve on the shank; the pin acting, e.g. through a plunger 68 to hold said pilot member in its forward and outward position, the sleeve 60 having a flange 62 whereby, after a hole cutting operation and with a slug retained in the cutter 14, the flange serves as an abutment for driving the sleeve forwardly on the shank to cause the pilot member to eject the slug. The arbor may be part of a drilling fixture (Fig. 1, not shown) which has a guide bush 24 for the sleeve 60 and a yoke 28 which acts in conjunction with the flange 62 to eject the slug. The end of the pilot member 42 may be formed to pierce a sheet metal workpiece or drill a pilot hole therein before the cutter 14 engages the workpiece (Figs. 7-10, not shown). the piercing or cutting part may be tapered to continually wedge the pilot member into the slug to firmly retain it. When drilling conduit or frame members the slug may be positively retained on the pilot member by a ball and spring detent (Fig. 10, not shown) or by other detent means. For drilling thick workpieces 130 (Fig. 11), the pilot member 124 has a drilling tip 126 and a shoulder 128 adjacent thereto which engages the workpiece surface after only a shallow pilot hole is drilled. As the arbor and cutter are moved towards the workpiece the pilot member initially engages the workpiece under the bias of spring 70 which is insufficient to cause drilling. The pilot member is retracted by the arbor feed until a spring detent 138 engages a shoulder 134 which produces a greater feed force to cause drilling of the pilot hole. When the shoulder 128 engages the workpiece a higher feed force is generated to overcome the spring detent 138 and shoulder 134 so that the pilot member is then retracted against the spring 70 and without further drilling of the pilot hole.
