Title: Improvements in methods of moulding constructional plates from strips of fibrous material and a binder
IPC: B28B1/52
Filed: 1948-12-23
Abstract: 684,153. Moulding building plates, boards &c. EVENSEN, S. W. Dec. 23,1948, No. 33179/48. Class 87 (ii).  A board made of long, thin, fibrous material, e.g. wood wool, and a binder, e.g. cement, is formed by pressing the large side surfaces of the board, then applying pressure to the side edges of the board without further reduction in the thickness of the board. The material may be pressed between plates 1, 2, the plates secured in position, and then pressed again by side members a, b. The members a, b may have grooves and tongues for forming tongues and grooves in the board. More material may be filled into the centre of the mould than around the edges, by means of a central filling frame provided with a packing piston (see Fig. 2, not shown). In a modification the moulds may be arranged vertically the material being introduced from the top through a side edge. Wood meal or cuttings may be added to the material.

Abstract: 342,351. Automatic exchange systems. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, WILLIAMS, A. H., 28, South Bank Road, Edge Lane, and SCARLETT, F. A. S., 34, Fieldway, Garden Suburb, Wavertree, all in Liverpool: Nov. 1, 1929, No. 33307. [Class 40 (iv).] Group selectors are enabled to hunt over successive levels with the aid of a vertical wiper and a release magnet for the rotary movement only. The invention is described with reference to a switch having two sets of wipers. Series relay C on pulling up energizes the shunt-field relay G which locks up, and on falling back at the end of the digit energizes the rotary magnet and relay Q which locks up over the vertical wiper VW and reverses the connections of the line relay to prevent further digits from being sent by the register-controller. At the end of its stroke, R at springs r releases G which in turn releases R. If both trunks are busy G pulls up again and a further step is made. If the entire level is busy, the change over of 11th step springs s short circuit HA, HB (the test wipers now engaging a common contact) and operates the rotary release magnet RZ which locks up. When the wipers reach the rotary home position, rotary off-normal springs re-operate C (over rz<3>) in series with V. The wipers are lifted, the vertical magnet releasing RZ and then falling back. C holds up long enough to energize G which interacts with the rotary magnet as before. The vertical terminal of the last level in each group is dead and if the switch reaches the end of this level unsuccessfully Q is released and busy tone and flash wire 13 is connected up. When an idle line is found, HA or HB switches through. If both wipers find an idle line HA cuts off HB at the light armature ha<1>.

Abstract: 1512637 Vitreous fertilizer STANDARD TELEPHONES & CABLES Ltd 29 July 1975 [30 July 1974] 33573/74 Headings C1M and C1B A particulate fertilizer comprises a vitreous matrix including P 2 O 5  as a glass-forming oxide and modifying oxides selected from alkali metal and alkaline earth metal oxides and including at least one of K 2 O, CaO and MgO, the matrix incorporating nitrogen as calcium cyanamide, and the matrix being soluble in water so that, on immersion in water, the constituents are slowly released into solution. The glass may consist of, in mole per cent, K 2 O 10-35,CaO+MgO 18-50 and P 2 O 5  37-55. The calcium cyanamide may be added as powder to molten glass at, e.g., about 800‹C. in N 2 . The calcium cyanamide particles may initially be coated with a metaphosphate glass of lower softening point than the matrix glass. The fertilizer may be heated to below the glass softening point and exposed to boric oxide vapour to form a boron phosphate surface layer (e.g. 0À1-1Á in thickness), so that the fertilizer, when immersed in water, has an induction period before the nutrient release period, in which induction period little or no nutrient is released. Optional ingredients of the fertilizer include fungicides and trace nutrient elements (so that deficiency diseases in livestock are treated by fertilizing the animal's fodder). The fertilizer may be used, instead of applying it to soil, to treat water used in hydroponic plant growth.

Title: Improvements in driving gear for winding apparatus
IPC: B66D1/48
Filed: 1936-12-08
Abstract: 486,599. Winches. CLARKE, CHAPMAN, & CO., Ltd., WOODESON, W. A., and MIDGLEY, W. Dec. 8, 1936, No. 33678. [Classes 78 (ii) and 78 (v)] A winding-drum 4 is freely mounted on a driving sleeve 2 turning about a stationary shaft 1, or otherwise journalled. Keyed to the sleeve 2 are a driving pinion 3 and a panelcarrying cage 15. One end of the drum 4 has a flange 5 turned over to enclose a spring casing 6, and the other end has fixed to it, a ratchet wheel 13 engageable by the pawls 14 of the cage 15. A spiral spring 7 is attached at its inner end to the sleeve 2, and at its outer end to the casing 6. The flange 5 has a friction grip on the casing 6, effected by a plurality of pads 29 carried by the flange 5 and pressed by spring washers 10 on to the casing surface, adjustable nuts 11 giving the required pressure. A number of bell-crank levers 16, one for each pawl 14, are carried by the cage 15 and are rockable by a sliding thrust collar 17 to lift the pawls 14 out of engagement with the wheel 13 or to allow them to fall back thereon. The device allows of the cable being unwound to hook on to a load, the rotating drum tensioning the spring 7 when the pawls 14 are raised clear of the wheel 13. Should the cable be drawn off so far that the spring 7 becomes wound tight, the pads 29 allow of slipping round of the drum when the cable is further extended. On attachment of the load the pawls 14 are allowed to fall, and power is applied to the pinion 3, thus imparting a direct winding-on drive to the drum. Should the load be brought by external means toward the drum at a faster rate than the wind is taking place, as when the load is a floating object and is lifted by a wave, the spring 7 uncoils and turns the drum rapidly to keep the cable tight, the pawls 14 snapping over the ratchet teeth during this process.

Abstract: 1516442 Dispensing liquids by osmosis and gas pressure ALZA CORP 13 Aug 1976 [11 Sept 1975] 33834/76 Heading A5B [Also in Divisions B1 and Fl] A dispenser e.g. a buccal tablet 10, for dispensing an active agent composition 15 to a fluid-containing environment, comprises a wall 12 defining a compartment 13 which contains a mixture of the agent composition 15 and a gas-generating composition 16 which is activated by contact with the fluid. The wall 12 has a passage 14 for dispensing the agent and is made of a material that maintains its integrity during dispensing but is permeable to the fluid and impermeable to the agent 15 and gas-generating composition 16. At least one of the compositions 15, 16; or a further compound added to the mixture, is soluble in the fluid and, when in solution, creates an osmotic pressure gradient across the wall so that fluid is drawn into the compartment 13 to cause gas generation and therefore enhanced displacement of the agent from the dispenser 10. The mixture also may contain a surfactant to assist wetting and a foaming agent to aid dispensing. The dispenser may take the form of a parallelelepiped having two passages 14 (Figs. 2A, B, not shown) or a cartridge having a tapered passage 14 (Fig. 3, not shown), the latter type being suitable for dispensing a medicinal agent 15 into a body opening. Generally, however, the active agent 15 may be any composition that is dispensed to produce a useful result. The gasgenerating composition 16 is typically an effervescent couple such as an acid-base mixture, and several suitable chemicals are listed. Various suitable materials for all the components of the dispenser are described, as are processes for making the dispenser. Six examples are detailed. Typically, the ingredients may be mixed and compressed into a tablet which is then coated with the material to form the wall 12, the passage 14 being made by mechanical drilling.

Abstract: 913,813. Testing loud-speakers. MARCONI INSTRUMENTS Ltd. Aug. 27, 1959 [Oct. 29, 1958], No. 34600/58. Class 40 (4). [Also in Group XXXVI] Apparatus measuring frequency, harmonic, and intermodulation distortion due to non- linearity of the transfer characteristic of a transducer or transmission circuit comprises two oscillators at least one of which is frequency variable and whose outputs are mixed to a difference frequency applied to the input of the test apparatus, and means for mixing the apparatus output with signals from one oscillator, to a summation frequency applied to an amplitude measuring instrument through a narrow band-pass filter. In Fig. 1, the outputs f 1 , f 2  of fixed and variable oscillators O 1 , O 2  (f 1 #f 2 ) are mixed at M 1 , and the difference (f 1 -f 2 ) supplied over lowpass filter LF 1  to loud-speaker LS associated with microphone MM whose output is mixed with f 2  at M 2  and the sum (f 1  -f 2 )+f 2 =f 1  pass through narrow band filter BF1 to measuring instrument RM as measure of output level at fundamental frequency f 1 . In Fig. 2, the frequencies f 1  f 2  are subdivided by factor n at D 1 , D 2  before application to mixer M 1  so that the test frequency is (# 1  - # 2 )/n and the output of M 2  is zero until a harmonic of order n is generated in the system, when a component at frequency f 1  deflects RM to indicate the harmonic amplitude. In Fig. 3, signals # 2  and # 3  (= # 1 + ##) from O 2  and O 3  are mixed to a difference signal (f 1  - - f 2 ) + #f selected by low-pass filter LF2 and applied to loud-speaker LS together with (# 1  -# 2 ) from O 1  and O 2 . The microphone output contains signals (# 1 -# 2 ) and (# 1 -# 2 )+ ## with their harmonics and also even and odd order intermodulation products n #f, (f 1  -f 2 )-n ##. The even order products are directly selected and measured on RM by selecting an appropriate one of band-pass filters BF1, BF2, BF3, &c., by switches S1 S2. The odd order product is measured by increasing all oscillator frequencies by n #f so that the energization frequencies to the loud-speaker remain (# 1 -# 2 ) and (# 1 -# 2 )+ #f, and switch S1 connects the microphone output to be mixed additively with (# 2  + n ## ) from O 2  while the resultant f 1 =(f 1 -f 2 )-n #f+f 2 + n #f is extracted by BF1 for measurement on RM.
