Title: Improvements in and relating to fasteners for anchoring boarding to a wall
Inventor: KOENIGSHOF GERALD ALAN
IPC: E04F13/08
Filed: 1964-03-16
Abstract: 1,038,000. Spiked strips. TIMBER ENGINEERING CO. March 16, 1964, No. 10965/64. Heading F2H. [Also in Division E1] For mounting boarding 14, Fig. 7, on boards 4, e.g. of plywood (possibly covered with sealing paper and fixed to vertical studding 3), flat strip or wire or, as shown in Figs. 4, 5 and 7, channel strip 5, bearing teeth 11 (with points 12) and lugs 6 each presenting a lip 8, is secured as by nails 13 to the studding 3, Fig. 7. A board 14 is mounted by applying its featheredge under a horizontal line of lugs 6 of adjacent strips 5 and pushing or tapping with a soft hammer its lower edge on to the points 12 to overlap lower lugs 6. The teeth 11 and lugs 6 may be made from wire and may be barbed or coated with adhesive for greater holding. The U-member which forms a pair of teeth 11 may have a wide base 10, Fig. 5. In Figs. 10, 12 (not shown), the lip 19 is formed as part of the toothed member 18, with squarer-ended teeth 20 and welded, soldered or stuck to the top of a ridge 14 formed in a flat strip 5<SP>1</SP>. In Figs. 8, 9 (not shown), the tops of the ridges 14 are inclined to the strip plane so that a simple tab forming the lip and secured on each top is also inclined, at an angle approximating to that of the outer surface of mounted boarding. In this case, a separate simple U-member with teeth but without a wide base 10 is secured on the ridge top on top of the tab with its curved teeth in a direction generally perpendicular to the boarding face.

Title: Agglomeration process for pulp from sugar factories and a resulting product intended for cattle feeding
IPC: A23K1/14
Filed: 1928-04-13
Abstract: 320,883. Soc. Anon. des Sucreries Ternynck, and Ternynck, L. April 13, 1928. Feeding in definite proportions.- Relates to apparatus for mixing in measured quantities pulp from sugar factories and molasses. Pulp from a hopper 2 falls into a skip 1, until the skip is overbalanced by the weight of the pulp, which falls into a mixing vessel 7 having rotary blades 9. When the skip 1 tilts, the hopper 2 is closed and a catch 5 released, allowing a skip 3 for molasses to move into loading position. When the skip 1 empties, it is moved back to loading position by a counter-balance 1<a>, and causes the hopper 2 and molasses outlet 4 to open. The tilting of the skip 3 closes the outlet 4, and moves a catch 6 into a position allowing the skip 1 to tilt when filled. Reference has been directed by the Comptroller to Specification 4919/07, [Class 5, Agricultural appliances, Farmyard &c.].

Title: Improvements in machines for projecting pictures, more particularly for use with sound reproducing apparatus
IPC: G03B31/02
Filed: 1922-04-19
Abstract: 200,242. Bohn, G. April 19, 1922. Lantern. slides. - Apparatus for projecting still pictures, especially intended for use with sound-reproducing machines, is provided with means for controlling the movement of a slide carrying a series of pictures in such a manner that the individual pictures of a series are shown for different predetermined periods of time, such means comprising a series of stop members which are independently withdrawn m succession, after predetermined time intervals, from engagement with the slide. The lantern slide, Fig. 11, is in the form of a strip carrying a number of picture sections 137, and is fed vertically downwards through a slot by gravity. The side-pieces 133 of the slide are formed with slots 163 arranged in four lines registering with four reciprocating plungers, one or other of which enters the corresponding slot and holds the slide against movement. The plungers normally tend to engage the slide and are withdrawn in succession at regular intervals of time; when the one which is holding the slide is withdrawn, the slide drops a space and is held by another plunger which is not necessarily the next one to be withdrawn. By suitable arrangement of the slots, the period of time for which a picture is shown can be varied from one interval to three intervals. The slide instead of being formed with slots may be formed with notches 171, Fig. 12, of different depths, or may be provided with projections.

Abstract: 642,622. Switch contacts. CRABTREE & CO., Ltd., J. A., BESAG, E., and WINTLE, T. D. G. April 24, 1948, No. 11332. [Class 38(v)] Each contact b of a 3-phase motor starter is composed of sheet copper about 0.018 inch thick thereby providing light weight and avoiding bounce when the silver buttons c engage fixed contacts, Fig. 3 (not shown). Flanges e give the contact rigidity and guide it in a recess a<SP>1</SP> in the movable insulating carrier a. Each contact is resiliently mounted by stems f inserted horizontally through slots i in the carrier, a spring g being thereby compressed between the tail of each stem and the carrier The stems are then rotated through 90 degrees, permitted by holes concentric with the slots i, and inserted through slots k in the contact b. Holes in the contact, concentric with the slots k, permit turning of the stems back to the horizontal and the enlarged stem heads f thus secure the contacts and are prevented from subsequent rotation by horizontal bulges b' formed in the contact. In Fig. 6 (not shown), the ends of the contact are also bent over, the ends serving as abutments for a blade spring taking the place of springs g. Alternatively, the contact may be strengthened by a longitudinal dishing formed centrally thereon.

Abstract: 235,164. Selas Akt.-Ges. June 4, 1924, [Convention date]. Mixing fluids in flow.-Relates to safety devices for gas and air mixing plants of the kind which employs a control flame so arranged that the supply of gas is cut off through thermally operated devices when undesirable changes occur in the composition of the mixture., and comprises the addition of thermally operated means for giving an alarm if the plant is started up when the control flame is not alight. When the circuit of an alarm 12 is supplied from the same mains as the motor which drives the plant, the alarm is rendered inoperative when the main switch 8 is opened; but where the plant is driven non-electrically, the alarm circuit may be rendered operative or inoperative by a switch connected with the starting lever of the engine. When the alarm circuit is in the operative state it is normally kept open by the spring contact 6 standing away from the fixed contact 7, but on extinction of the flame 1 the bimetallic strips 2 unbend and force the contact 6 to the left so as to close the alarm circuit.
