Title: Improvements in and relating to hand-looms
IPC: D03D29/00
Filed: 1948-11-26
Abstract: 685,525. Hand looms. OTVOS, Z., and VAGO, I. Nov. 26, 1948. No. 30762/48. Class 142 (ii). The shedding and picking mechanisms are actuated from the lay by means of flexible connecting members, the members operating the heald shafts being connected to the lay and those operating the picking mechanism being connected to the loom frame. As shown in Fig. 1 the heald shafts 1 are suspended on hooks 2, which may be lifted by means of lugs 5 provided on each side of a prismatic body 4 rotatably mounted on the end of a lever 6, the other end of the lever being operated by a cable 7 connected to the lay 9. The body 4 and consequently the hooks and shafts are lifted and lowered as the lay 9 reciprocates, a step-by-step rotary motion being imparted to the body 4 by known means, e.g. a ratchet wheel and pawl. The picker 10 is operated by a spring 11 and is drawn back by a nut 15 on a cable 13, which is led over a pulley 12 to the loom frame, the outward movement of the lay serving to pull back the nut and consequently the picker ; a spring 16 attached to the other end of the cable 13 draws the nut forward to clear the picker when the lay moves inward. A spring-biased detent 17 holds the picker in its " cocked " position and is released at the moment of picking by a bar 19 contacting the detent. The bar 19 is slidable in members 26 attached to the frame, the sliding being controlled by a spring 20 and a cable 22 attached to a hook 2, actuated by the member 4 and so arranged that the rod 19 will operate the detent at the required stroke of the lay. Collars 23 limit the movement of the bar. In a second embodiment, Figs. 5 and 6 (not shown) the nut 15 for the picker is replaced. by a striking rod having a spring and cable operating mechanism.

Title: Improvements in and relating to fluid flow measuring instruments
IPC: G01F1/82
Filed: 1952-12-04
Abstract: 717,897. Fluid flowmeters. GENERAL ELECTRIC CO. Dec. 4, 1952 [Dec. 6, 1951], No. 30788/52. Class 97(2) [Also in Group XXXVIII] In a fluid flowmeter, a uniform angular velocity is imparted to the fluid-by means rotating, at a constant speed and the fluid is then caused to strike a member, which is rotatable, against the action of restraining means, by the torque applied by the fluid and is adapted to indicate the mass rate of flow. As shown in Fig. 1, the flowmeter comprises a casing 1 with fluid inlet and outlet 2, 3 and having therein an impeller 4 and turbine 5 each with several peripheral slots 6, 7. The impeller is mounted on a hollow shaft 11 in an end bracket 12 and is continuously rotated through gearing 10 by a constant speed motor 8. Carried by the shaft 11 and an end bracket 14 is a shaft 13 on which the turbine 5 is rotatable, this turbine normally being held stationary by a spring 15. The fluid is caused to flow through the casing as by a pump (not shown). Angular velocity is imparted to the fluid by impeller 4 and the turbine is rotated against the action of spring 15 until the angular momentum is dissipated. The deflection of the turbine and therefore the mass rate of flow is indicated by an index 17 and a scale on the turbine which can be read through a window 16. In another form-the motor for-driving the impeller is housed in the upstream bracket 12 and the turbine shaft carries the permanent magnet rotor of an electrical pick off for actuating a remote indicator, Fig. 3 (not shown). The slots 6. 7 in the impeller and turbine may extend radially. Two such forms of flowmeter are described in one of which the mass rate is indicated by a pointer moving over a scale, (Fig. 6) while in the other a remote indication of the mass rate is provided by electrical means (Fig. 5). In an alternative, the turbine may be continuously driven to a predetermined position, the power measured to preserve this position being indicative of the mass rate of flow.

Title: An improved safety device for excess temperatures
IPC: G08B17/08
Filed: 1952-12-10
Abstract: 728,853. Temperature alarms. THIELMANN, S. Dec. 10, 1952 [Dec. 18, 1951], No. 31265/52. Class 118 (1).  An arrangement for giving an alarm when a predeter. mined temperature is reached comprises a glass capsule having a liquid or solid filling and designed to burst at a predetermined temperature and a spring-loaded plunger held in place by the capsule, so that, when the latter bursts, the plunger moves to release a catch and thereby actuate an alarm. The capsule c rests upon a support b within a casing a and maintains a spring-loaded plunger d in its elevated position so that the upper end of the plunger projects from the casing and so holds an arm g against the action of a spring. When the capsule bursts the plunger d falls and the arm g is thus free to move and operate the alarm. In a modification, Fig. 5, seen from above, the arm g is replaced by two members h acted on by springs in the directions of the arrows and held in place by the tapered end of the plunger d passing through holes in the extremities of the members h. The casing may be made of heat-insulating material, Fig. 6 (not shown), so that the device may be employed in situations where the ternperature is normally higher than that at which the capsule bursts.
Patent GB-343877-A (GB)
Title: Improvements in and relating to the manufacture of phenolformaldehyde condensation products
IPC: C08G8/00
Filed: 1929-10-15
Abstract: Phenol formaldehyde condensation products.-Hardenable phenol - formaldehyde condensation products are made by way of phenol polyalcohols as intermediate products by adding the phenol in portions to a mixture of formaldehyde in excess (i.e. more than two molecules formaldehyde per molecule of phenol) and at least 3 per cent (calculated on the phenol) of caustic soda or ammonia dissolved in water or an equivalent quantity of another base such as dimethylamine or piperidine, and adding readily saponifiable esters, particularly lactic acid esters, to the mass when ready for pouring into moulds.  Neutralization of the alkali, preferably performed when dehydration is almost finished, should not be effected by acids capable of momentarily hardening the resin when added in excess such as hydrochloric or sulphuric acid, but by organic aliphatic, hydroxy or aromatic acids such as acetic, lactic or salicylic acids. Glycerin esters of acids such as lactic, which yield hardenable esters, and preferably glycerin mono-or dilactate, may be added to reduce the turbidity; glycol esters act similarly but not so effectively.  In an example a solution of caustic soda is added to a formaldehyde solution and phenol is run in in portions; distillation is then performed under a vacuum, excess lactic or acetic acid added and finally a lactic acid ester is added.  Specifications 159,461, 191,417 and 267,901, [all in Class 2 (iii), Dyes &c.], are referred to.

Title: Production of pyridines
Inventor: COATES HAROLD
IPC: C07D213/127
Filed: 1965-07-22
Abstract: A process for the production of pyridine or substituted pyridines comprises heating a d -valerolactam at a temperature of from 200 DEG to 800 DEG  C. in the presence of a catalyst system which causes dehydration and dehydrogenation of the lactam to take place in a single stage, the catalyst being so selected that dehydration of the lactam occurs prior to the dehydrogenation with the production of the corresponding pyridine. Amino pyridines are produced by including ammonia in the reaction mixture. Catalysts specified include copper chromite and metals of Group VI and of the platinum group. Many inert and active carriers for the catalyst are specified silica, alumina and aluminium phosphate being preferred.  Preferably hydrogen is admixed with the lactam vapours before passing over the catalyst. Examples are furnished.ALSO:Among catalysts employed in the dehydration and dehydrogenation of d -valerolactams to pyridines is a palladium on aluminium phosphate catalyst (Example 7) prepared by impregnating pelletised aluminium phosphate with a surface area 200 m2/gm with a solution of palladous chloride and ammonium chloride and reducing the product in a stream of hydrogen.
