Title: Improvements in Grenades.
Inventor: PARKES SAMUEL ROWLAND
IPC: F42B12/20
Filed: 1916-03-10
Abstract: 124,527. Parkes, S. R. March 10, 1916. Projectile fuses. - Relates to grenades provided with a spring striker wntrolled by an external lever, and consists in adding thereto a catch device for holding the spring striker after the lever has been released and until impact takes place. In the form shown in Fig. 2, the striker B, which has a neck b<1> retained by a lever D in the usual way, is made with a second neck b" embraced by two half rings d' surrounded by a cap d<2> held in place by the lever. When the grenade is thrown, the lever is thrust off in the usual way, and on impact, the cap d<2> is dislodged, releasing the rings d<1> and allowing the striker to fire the grenade. In a modification, the half rings d<1> are replaced by hinged arms and the cap d<2> by a bridge-piece over the free ends of the arms, a blade spring being secured underneath the lever D.

Title: Improvements in and relating to the manufacture of dextrose
IPC: C13K1/10
Filed: 1935-02-04
Abstract: In the method of crystallizing starch converted dextrose solution described in U.S.A. Specifications 1,722,761 and 1,976,361, in which the crystallization is carried out in a vacuum pan in three stages comprising a concentrating stage, a graining stage and a building up stage wherein the crystalline dextrose is deposited around the already formed nuclear crystals, the liquor is diluted during the third stage so as gradually to lower the boiling point by the addition of further original solution at a rate greater than that at which water is being evaporated from the solution.  Water may be added instead of the original solution, the crystallizing supersaturation being maintained in either case. Vacuum pans operating with either constant or variable vacuum may be used. British Specifications 227,140 and 232,160, [both in Class 32], also are referred to.

Title: Analogue to digital converter
IPC: H03M1/40
Filed: 1976-01-29
Abstract: 1531532 A-D converters HEWLETT-PACKARD CO 29 Jan 1976 [10 Feb 1975] 03591/76 Heading H3H A recirculating a#d converter comprises a delay 700 outputting to a means 400 providing at least the inverse and a selected function of its input, and a comparator 20 giving a digital output as in each bit cycle the original signal, multiplied by means 400 is represented. In operation V o  is fed to means 400, inversely fed back from transformer secondary 402 and presented to comparator 20, thus compensating for any D.C. offset, dependent on its sign fed back through 404 or 405 and represented to the comparator after negative feedback. The gain of the cascade and the comparator reference may be varied to compensate for thermal drift and the comparator may be clocked, to a position O, during each off duty half-cycle so it. produces an equal number of up/down decisions. In an embodiment using the means of Fig. 9 V o  is passed via coil 406 m times to build up a voltage to be converted of A<SP>m</SP>V o , where A is the transformation ratio. If Vx # O this embodiment may be used to find the difference between V o  and Vx. If Vx = V o  then the converter can build up a signal to a level to be converted and if m=2<SP>P</SP> where P = 0, 1, 2 . . . then the converter may be used as a floating point coder.

Pipe 19, advancing upon a pallet from the left along roller conveyer 18, is gripped by pipe clamps 20 and is rotated about shaft 51 till it assumes the inverted position shown, when it continues to the right upon pallet 40. Pipe clamps 20 are carried by turret assembly 17 (see later) which slides up column 16, its position thereon being adjusted by handle 27 working metering screw 26 engaging a thread in said turret assembly. The rotation of the turret assembly 17 is effected by driven shaft 24 (see later), the drive from motor 22 passing through shaft 138 and clutch 23 to said shaft 24. Clutch 23 comprises part 137 fixed to shaft 138, part 139 being fixed to bracket 136, and part 140 slidably keyed to shaft 24 and operated from air cylinder 141 by a linkage pivoting at 143 so that said part 140 either clutches shaft 24 to shaft 138 to drive the former or "clutches" shaft 24 to bracket 136 so as to brake said shaft 24. Fig. 4. Pipe clamps 20. The pipe clamps 20 are arranged in pairs on the ends of and this separates arms 83 of a pipe clamp 'which is secured by block 54 and screws 57 to shaft 51 which latter is rotated from driven shaft 24 through worm 49 and worm wheel 50, the whole of this turret assembly 17 being clamped to column 16 through clamping ring 44 secured by screws 47.

Title: Process for the production of polyolefines containing expanding agents
IPC: C08J9/10
Filed: 1965-01-29
Abstract: Polyolefines containing expanding agents are prepared by mixing finely divided polyolefine powder having up to 85% by weight of a grain size of less than 150 microns, with from 0.1 to 5.0% by weight of a solid powdered expanding agent until sintering takes place, the decomposition temperature of the expanding agent not being lower than the sintering temperature. Suitable polyolefines are polymers or copolymers of ethylene, propylene or butene-1. The mixing may be effected in a mixer capable of being heated. Certain distributions of the particle sizes of the polyolefine powder are particularly favourable.  The amount of expanding agent used is preferably from 0.3 to 1.5% by weight. The grain size of the expanding agent should not exceed 50 microns.  Suitable expanding agents are azodicarbonamides, diphenyl oxide-4,41 -disulphohydrazide and inorganic expanding agents, e.g. a mixture of sodium bicarbonate and boric acid.  The mixer may contain a high speed stirring means and one or more stationary or oppositely moving scrapers.

Title: Extracts from vegetable material
Inventor: MITCHELL WILLIAM
IPC: A61K8/58
Filed: 1953-02-12
Abstract: A process for preparing an extract from raw or partly prepared chlorophyll-containing vegetable matter, e.g. grass, alfalfa or nettles, comprises saponification of the so-called "oil-soluble chlorophyll", solvent extraction of the saponified products to remove unsaponifiable matter, acid treatment of the residue to liberate the chlorophyllins and fatty acids and then removal of the chlorophyllins by treatment with a solvent in which they are insoluble.  In an example dried grass meal is extracted with 85 per cent v/v acetone, to give an "oil soluble chlorophyll" (after separation of associated water-soluble matter) which is saponified with 15 per cent of its weight of sodium hydroxide (as an aqueous solution containing 10 grams of sodium hydroxide per 100 mls.) whereafter the mixture is cooled, diluted with water and the unsaponifiable matter extracted with hexane, the chlorophyllins, fatty acids, and associated substances being then liberated by addition of mineral acid, the mixture being then treated with light petroleum in which the chlorophyllins are insoluble and the light petroleum-soluble acidic matter being then distilled in vacuo from the associated impurities and is obtained as a pale-yellow to brown solid, or semi-solid crystalline mass from which sodium or other salts are prepared by the usual methods.  Lozenges, chewing gum, dentifrices, oral and therapeutic preparations, surgical and hygenic dressings are prepared embodying the salts of the extract.

Title: Loudspeaking telephone equipment
IPC: H04M1/60
Filed: 1947-02-13
Abstract: 629,014. Substation circuits. BROWN, W. G. Feb. 13, 1947, No. 4177. [Class 40 (iv)] In a loudspeaking substation variation in line impedance due to speech impinging on the distant subscriber's microphone is detected by a supersonic oscillator whose output is applied to the loudspeaker. High- and low-pass filters may then be suitably positioned in the circuit to prevent acoustic reaction. On an outgoing call, key K1 is thrown to complete the exchange loop and the number is dialled in the normal way, dialling and ringing tones being fed via retard coil R to the loudspeaker amplifier V2. When the called subscriber replies reduction of the line impedance causes supersonic oscillations from V3 to energize relay S sufficiently to open its early contacts 1, 2 whereupon S pulls up fully to the exchange battery, switching in the transmitter and connecting the input transformer T4 into the cathode circuit of V3. Subsequent modulation of the supersonic oscillations is thus passed to the loudspeaker amplifier V2, the high and lowpass filters HP and LP preventing feed-back from transmitter to loudspeaker. On incoming calls S pulls up immediately K1 is thrown, since the distant telephone is already connected to line. Key K2 is provided for connecting up a hand microtelephone and key K3 may replace relay S, the key being thrown when the called subscriber is heard.
